FairEmail-support

Har du et spørgsmål, så tjek venligst de ofte stillede spørgsmål nedenfor først. Nederst kan du se, hvordan du stiller yderligere spørgsmål, anmoder om funktioner samt indrapporterer fejl.

Indeks

Godkendelse af konti

I de fleste tilfælde vil hurtig opsætningen automatisk kunne identificere den rigtige opsætning.

Mislykkes hurtig opsætningen skal du manuelt opsætte en konto (for at modtage e-mail) samt identitet (for at sende e-mail). Til dette behøver du IMAP- og SMTP-serveradresserne og portnumrene, om enten SSL/TLS eller STARTTLS skal anvendes og dit brugernavn (for det meste, men ikke altid, din e-mailadresse) samt adgangskode.

En søgning på IMAP samt navnet på tjenesteleverandøren er ofte tilstrækkeligt til at finde den rette dokumentation.

I visse tilfælde vil du skulle aktivere ekstern adgang til din konto og/eller benytte en speciel (app-)adgangskode, eksempelvis når tofaktorgodkendelse er aktiveret.

Til godkendelse:

Se hér for almindeligt forekommende fejlmeddelelser og løsninger.

Kendte problemer

  • En fejl i Android 5.1 og 6 medfører, at apps sommetider viser et ukorrekt tidsformat. Skiftning af Android-indstillingen Benyt 24-timers format kan midlertidigt løse problemet. En løsning blev tilføjet.
  • En fejl i Google Drive medfører, at filer eksporteret til Google Drive kan være tomme. Google har løst problemet.
  • En fejl i AndroidX medfører, at FairEmail undertiden går ned ifm. lange tryk eller strygebevægelser. Google har løst problemet.
  • En fejl i Android medfører af og til et nedbrud med en "... Undtagelse under behandling af realtids databasedata ... Kunne ikke læse række...". En løsning blev tilføjet.
  • En fejl i Android medfører, at FairEmail går ned med en "*... Fejlbehæftet notifikation sendt ... * "på visse enheder en gang efter opdatering af FairEmail og tryk på en notifikation.
  • En fejl i Android medfører af og til et nedbrud med "*... ActivityRecord ikke fundet for ... * "efter opdatering af FairEmail. Geninstallering af (kilde) kan løse problemet.
  • En fejl i Android medfører af og til et nedbrud med "... InputChannel ikke initialiseret ... på visse enheder.
  • En fejl i LineageOS medfører af og til et nedbrud med en "... java.lang.ArrayIndexOutOfBoundsException: lenght=...; index=... ...
  • En fejl i Nova Launcher på Android 5.x får FairEmail til at gå ned med en java.lang.StackOverflowError fejl, når Nova Launcher har adgang til tilgængelighedstjenesten.
  • Mappevælgeren viser undertiden ingen mapper af endnu ukendte årsager. Dette lader til at være rettet.
  • En fejl i AndroidX gør det svært at gribe fat i hurtig-rulningsobjektet. En løsning blev tilføjet.
  • Kryptering med YubiKey resulterer i en uendelig løkke. Dette synes forårsaget at en fejl i OpenKeychain.
  • Rulning ned til en internt linket position i originalbeskeder fungerer ikke. Dette kan ikke rettes, da originalbeskedvisningen udgør en del af selve rulningsvisningen.
  • En forhåndsvisning af en beskedtekst vises ikke (altid) på Samsung-ure, da setLocalOnly-parameteren synes at blive ignoreret. Beskedforhåndsvisningstekster fremgår korrekt på Pebble 2-, Fitbit Charge 3- og Mi band 3-wearables. Se også denne FAQ.
  • En fejl i Android medfører af og til et nedbrud med "... Ugyldig forskydning... Gyldigt område er ... når tekst er valgt og der trykkes uden for den valgte tekst. Denne fejl er rettet i Android 6.0.1.
  • Interne (anker-) links vil ikke fungere, da de oprindelige beskeder vises i et indlejret WebView i en rullevisning (samtalelisten). Dette er en Android-begrænsning, der ikke kan rettes eller omgås.
  • Sprogdetektering fungerer ikke længere på Pixel-enheder med/ opgraderet til Android 11

Planlagte funktioner

  • Synkronisere efter behov (manuelt)
  • Semiautomatisk kryptering
  • Kopiere besked
  • Farvede stjerner
  • Notifikationsindstillinger pr. mappe
  • Vælg lokale billeder til underskrifter (ingen af dem tilføjes, da dette kræver billedfilhåndtering, og da billedersom standard alligevel ikke vises i de fleste e-mail klienter)
  • Vis beskeder matchet af en regel
  • ~~ManageSieve ~ ~ (der er ingen vedligeholdte Java-biblioteker med en passende licens og uden afhængigheder, og desuden har FairEmail sine egne filterregler)
  • Søg efter beskeder med/uden vedhæftelser (dette kan ikke tilføjes, da IMAP ikke understøtter søgning efter vedhæftninger)
  • Søg efter en mappe (filtrering af en hierarkisk mappeliste er problematisk)
  • Søgeforslag
  • Autokrypteringsopsætningsmeddelelse (afsnit 4.4) (det kan ikke anbefales at lade en e-mail klient håndtere følsomme krypteringsnøgler til en usædvanlig brugsinstans, når OpenKeychain også kan eksportere nøgler)
  • Generiske fællesmapper
  • Nye pr. konto beskednotifikationstidsplaner (implementeret ved tilføjelse af en tidsbetingelse til regler, så beskeder kan slumres i udvalgte perioder)
  • Kopiering af konti og identiteter
  • Knibezoom (ikke muligt på pålidelig vis i en rulleliste, i stedet kan den fulde beskedvisning zoomes)
  • Mere kompakt mappevisning
  • Opret lister og tabeller (dette kræver et tekstredigeringsværktøj til righoldig tekst, se denne FAQ)
  • Tekststørrelsesknibezoom
  • Vis GIF'er
  • Temaer (et lysegråt og mørkt tema er tilføjet, da disse serud til at være dem, de fleste ønsker)
  • Enhver dag-tidsbetingelse (enhver dag passer ikke rigtig ind i fra/til dato/tid betingelsen)
  • Send som vedhæftning
  • Widget til udvalgt konto
  • Påmindelse om at vedhæfte filer
  • Vælg domæner at vise billeder til (dette vil være for kompliceret at bruge)
  • Fælles stjernemarkerede beskedervisning (der er allerde en særlig søgestreng herfor)
  • Notifikation for flytningshandling
  • S/MIME-understøttelse
  • Søg efter indstillinger

Alt på denne liste er i tilfældig orden og bliver muligvis tilføjet i den nærmeste fremtid.

Hyppigt anmodede funktioner

Designet er baseret på mange debatter, og er du interesseret, kan du også debatere det i dette forum. Designmålet er minimalisme (ingen unødvendige menuer, knapper mv.) og ikke-distraherende (ingen smarte farver, animationer mv.). Alle viste ting skal på en eller anden måde være nyttige og skal placeres omhyggeligt for nem brug. Skrifttyper/-størrelser, farver mv. skal være materielt design, når det er muligt.

Ofte stillede spørgsmål

Jeg har et andet spørgsmål.

(1) Hvilke tilladelser kræves, og hvorfor?

Flg. Android-tilladelser kræves:

  • fuld netværksadgang (INTERNET): For at sende/modtage e-mails
  • se netværksforbindelser (ACCESS_NETWORK_STATE): For at monitere Internetkonnektivitetsændringer
  • kør ved opstart (RECEIVE_BOOT_COMPLETED): For at starte monitering ved enhedsstart
  • forgrundstjeneste (FOREGROUND_SERVICE): For at køre en forgrundstjeneste på Android 9 Pie og senere, se også næste spørgsmål
  • forhindre enhed i at sove (WAKE_LOCK): For at holde enheden vågen, mens beskeder synkroniseres
  • in-app fakturering (BILLING): For at tillade køb direkte i appen
  • Valgfri: læse dine kontakter (READ_CONTACTS): For at autofuldføre adresser samt vise fotos
  • Valgfri: læse indholdet af dit SD-kort (READ_EXTERNAL_STORAGE): For at acceptere filer fra andre, forældede apps, se også denne FAQ
  • Valgfri: benyt fingeraftrykshardware (USE_FINGERPRINT) og benyt biometrisk hardware (USE_BIOMETRIC): For at benytte biometrisk godkendelse
  • Valgfri: find konti på enheden (GET_ACCOUNTS): For at vælge en konto ifm. Gmails hurtig-opsætning
  • Android 5.1 Lollipop og ældre: Benyt konti på enheden (USE_CREDENTIALS): For at vælge en konto ifm. Gmails hurtig-opsætning (senere Android-version benytter ikke denne forespørgsel)
  • Android 5.1 Lollipop og ældre: Læse profil (READ_PROFILE): For at læse dit navn ifm. Gmails hurtig-opsætning (senere Android-version benytter ikke denne forespørgsel)

Valgfrie tilladelser understøttes kun på Android 6 Marshmallow og nyere. Tidligere Android-versioner anmoder om at tildele de valgfri tilladelser ved installation af FairEmail.

Flg. tilladelser kræves for at vise antallet af ulæste beskeder som en badge (se også denne FAQ):

  • com.sec.android.provider.badge.permission.READ
  • com.sec.android.provider.badge.permission.WRITE
  • com.htc.launcher.permission.READ_SETTINGS
  • com.htc.launcher.permission.UPDATE_SHORTCUT
  • com.sonyericsson.home.permission.BROADCAST_BADGE
  • com.sonymobile.home.permission.PROVIDER_INSERT_BADGE
  • com.anddoes.launcher.permission.UPDATE_COUNT
  • com.majeur.launcher.permission.UPDATE_BADGE
  • com.huawei.android.launcher.permission.CHANGE_BADGE
  • com.huawei.android.launcher.permission.READ_SETTINGS
  • com.huawei.android.launcher.permission.WRITE_SETTINGS
  • android.permission.READ_APP_BADGE
  • com.oppo.launcher.permission.READ_SETTINGS
  • com.oppo.launcher.permission.WRITE_SETTINGS
  • me.everything.badger.permission.BADGE_COUNT_READ
  • me.everything.badger.permission.BADGE_COUNT_WRITE

FairEmail fører en liste over adresser, hvorfra og -til du modtager og sender beskeder, og denne liste benytter til kontaktforslag, når der ikke er tildelt kontakttilladelse i FairEmail. Dette betyder, at du kan benytte FairEmail uden Android-kontaktleverandøren (Kontakter). Bemærk, at du stadig kan vælge kontakter uden at tildele FairEmail kontakter-tilladelser, kontaktforslag alene fungerer dog ikke uden kontakter-tilladelser.


(2) Hvorfor vises en permanent notifikation?

En lavprioritets, permanent statusbjælkenotifikation med antallet af konti, som monitoreres, samt antallet af afventede operationer (se næste spørgsmål) vises for at forhindre Android i at afslutte den tjeneste, der håndterer den løbende modtagelse af e-mail. Dette var allerede nødvendigt, men med introduktionen af døsningstilstanden i Android 6 Marshmallow er dette mere end nogensinde nødvendigt. Døsningstilstanden stopper alle apps nogen tid efter, at skærmen slukkes, undtagen for apps, som har startet en forgrundstjeneste, der kræver visning af en statusbjælkenotifikation.

De fleste, hvis ikke alle, øvrige e-mail apps viser ingen notifikation med den "bivirkning", at nye notifikationer ofte ikke (eller for sent) rapporteres, samt at notifikationer ikke sendes (eller sendes for sent).

Android viser ikoner for højprioritets statusnotifikationer først og skjuler FairEmails notifikationsikon, hvis der ikke er plads til at vise yderligere ikoner. I praksis betyder dette, at statusbjælkenotifikationer ikke optager plads på statusbjælken, medmindre der er ledig plads.

Statusnjælkenotifikationen kan deaktiveres via FairEmails notifikationsindstillinger:

  • Android 8 Oreo og senere: Tryk på Modtagekanal-knappen og deaktivér kanalen via Android-indstillingerne (dette deaktiverer ikke notifikationer for nye besked)
  • Android 7 Nougat og tidligere: Aktivér Benyt baggrundstjenester til synkronisering af beskeder, men husk at læse bemærkningen under indstillingen

For at fjerne notifikationen kan du kan skifte til periodisk beskedsynkronisering i modtagelsesindstillingerne, dog vil dette muligvis forbruger mere strøm. Se hér for flere detailjer vedr. batteriforbrug.

Android 8 Oreo viser muæigvis også en statusbjælkenotifikation med teksten Apps kører i baggrunden. Tjek hér vedr., hvordan du kan deaktivere denne notifikation.

Anvendelse af Firebase Cloud Messaging (FCM) er foreslået i stedet for en Android-tjeneste med en statusbjælkenotifikation, men dette vil enten kræve e-mail udbydere, som sender FCM-meddelelser, eller en central server, hvor alle meddelelser samles mhp. afsendlse af FCM-meddelelser. Førstnævnte vil ikke komme til at ske, og sidstnævnte ville have betydelige datafortrolighedskonsekvenser.

Er du kommet hertil via et klik på notifikationen, så vil næste klik åbne den fælles indbakke.


(3) Hvad er operationer, og hvorfor afventer de?

Lavprioritets statusbjælkenotifikationen viser antallet af afventende operationer, som kan være:

  • tilføj: Føj besked til fjernmappe
  • flyt: Flyt besked til en anden fjernmappe
  • kopiér: Kopiér besked til en anden fjernmappe
  • hent: Hent ændret (pushed) besked
  • slet: Slet besked i fjernmappe
  • set: Markér beskeder som læste/ulæste i fjernmappe
  • besvaret: Markér beskeder som besvaret i fjernmappe
  • stjernemarker: Tilføj/fjern stjerne i fjernmappe
  • nøgleord: Tilføj/fjern IMAP-markering i fjernmappe
  • etiket: Sæt/nulstil Gmail-etiket i fjernmappe
  • overskrifter: Download beskedoverskrifter
  • råformat: Download beskeder i råformat
  • brødtekst: Download beskedindholdstekst
  • vedhæftning: Download vedhæftning
  • synk: Synk lokal- og fjernbeskeder
  • abonnér: Abonnér på fjernmappe
  • udrens: Slet alle beskeder fra fjernmappen
  • send: Send besked
  • findes: Tjek om besked findes
  • regel: Eksekvér regel på brødtekst

Operationer behandles kun, såfremt en forbindelse til e-mailserveren findes, eller under manuel synkronisering. Se også denne FAQ.


(4) Hvordan kan jeg benytte et ugyldigt sikkerhedscertifikat/tom adgangskode/simpel tekstforbindelse?

... Ikke-betroet ... ikke i certifikatet ...
... Ugyldigt sikkerhedscertifikat (kan ikke bekræfte identet på server)...

Du bør forsøge at løse dette ved at kontakte din udbyder eller ved at få et gyldigt sikkerhedscertifikat, da ugyldige sikkerhedscertifikater er usikre og tillader mand-i-midten-angreb. Er penge en hindring, kan du få gratis sikkerhedscertifikater fra Let's Encrypt.

Alternativt kan du acceptere fingeraftryk på ugyldige servercertifikater som dette:

  1. Sørg for at benytt en betroet Internetforbindelse (ingen offentlige Wi-Fi netværk mv.)
  2. Gå til opsætningsskærmen via navigeringsmenuen (stryg fra venstre side indad)
  3. Tryk i trin 1 og 2 på Håndtér og tryk på den defekte konto og identitet
  4. Tjek/gem kontoen og identiteten
  5. Markér afkrydsningsfeltet under fejlmeddelelsen og gem igen

Dette vil "fastgøre" servercertifikatet for at forhindre man-in-the-middle angreb.

Bemærk, at ældre Android-versioner muligvis ikke genkender nyere certificeringsmyndigheder såsom Let’s Encrypt, hvorfor forbindelser kan blive betragtet som usikre, tjek også hér.

Trust anchor til certificeringssti ikke fundet

... java.security.cert.CertPathValidatorException: Trust anchor til certificeringssti ikke fundet... betyder, at Androids standard trust manager ikke var i stand til at bekræfte servercertifikatkæden.

Du bør enten rette serveropsætningen eller acceptere fingeraftrykket vist nedenfor fejlmeddelelsen.

Bemærk, at dette problem kan skyldes af, at serveren ikke sender alle mellemliggende certifikater også.

Ingen adgangskode

Dit brugernavn er formentlig let at gætte, så dette er usikkert.

Simpel tekst-forbindelse

Dit brugernavn, adgangskode samt alle beskeder sendes og modtages ukrypteret, hvilket er meget usikkert, da et man-im-the-middle angreb nemt udføres på en ukrypteret forbindelse.

Vil du fortsat bruge et ugyldigt sikkerhedscertifikat, ingen adgangskode eller en simpel tekst-forbindelse, så skal usikre forbindelser aktiveres i konto- og/eller identitetsindstillingerne. STARTTLS bør vælges til simpel tekst-forbindelser. Aktiverer du usikre forbindelser, bør du kun oprette forbindelse via private, betroede netværk og aldrig via offentligt tilbudte netværk i lufthavne, hoteller mv.


(5) Hvordan tilpasses beskedvisningen?

Via trepriksmenuen kan du aktivere/deaktivere eller vælge:

  • tekststørrelse: Til tre forskellige skriftstørrelser
  • kompakt visning: Til flere kondenserede beskedelementer og en mindre beskedtekst skrifttype

I visningsafsnittet i indstillingerne kan man aktivere/deaktivere f.eks.:

  • Fælles indbakke: For at deaktivere den fælles indbakke og i stedet vise de valgte mapper fra den fælles indbakke
  • Tabelform: Til at vise en lineær liste i stedet for kort
  • Gruppér efter dato: Vis datooverskrift over beskeder med den samme dato
  • Konversationstråd: Til at deaktivere konversationstråd og i stedet vise beskeder individuelt
  • Konversationshandlingsbjælke: Til at deaktivere navigeringsbjælken nederst
  • Fremhæv farve: Til valg af afsenderfarve for ulæste beskeder
  • Vis kontaktfotos: Til at skjule kontaktfotos
  • Vis navne og e-mailadresser: Til at navne/navne og e-mailadresser
  • Vis emne uden kursiv: Til at vise beskedemnet som alm. tekst
  • Vis stjerner: Til at skjule stjerner (favoritter)
  • Vis beskedforhåndsvisning: Til at vise 1-4 linjers beskedtekst
  • Vis som standard adresseoplysninger: Vis som standard udvidet adresseafsnit
  • Vis automatisk opridelig besked for kendte kontakter: Tjek denne FAQ ang. at få vist originale beskeder automatisk for kontakter på din enhed
  • Vis automatisk billeder for kendte kontakter: Tjek denne FAQ for at få vist billeder automatisk for kontakter på din enhed

Bemærk, at kun downloadede beskedtekster kan forhåndsvises. Større beskedtekster downloades som standard ikke på afregnede (primært mobile) netværk. Dette kan ændres i forbindelsesindstillingerne.

Nogle har bedt om:

  • at få emnet vist med fed tekst, men fed benyttes allerede til fremhævelse af ulæste beskeder
  • at få stjernen flyttet til venstre, men det er meget lettere at betjene stjernen på højre side

(6) Hvordan logges ind på Gmail/G Suite?

Bruges Play Butik- eller GitHub-versionen af FairEmail, kan hurtigopsætningsguiden bruges for nem opsætning af en Gmail-konto og identitet. Gmail-hurtigopsætningsguiden er utilgængelig for tredjeparts-builds såsom F-Droid ditto, da Google kun har godkendte brugen af OAuth for officielle builds.

Ønsker man ikke at benytte en Gmail-konto på enheden, kan man enten aktivere adgang for "mindre sikre apps" og benytte sin kontoadgangskode (ikke anbefalet) eller aktivere tofaktorgodkendelse og benytte en app-specifik adgangskode. For brug af en adgangskode skal der opsættes en konto og identitet via opsætningstrin 1 og 2 i stedet for via hurtigopsætningsguiden.

Tjek denne FAQ ang., hvorfor kun konti på enheden kan benyttes.

Bemærk, at en app-specifik adgangskode kræves, når tofaktorgodkendelse er aktiveret.


App-specifik adgangskode

Tjek hér, hvordan en app-specifik adgangskode genereres.


Aktivér "Mindre sikre apps"

Vigtigt: Brug af denne metode anbefales ikke, da den er mindre pålidelig.

Vigtigt: Brugernavn/adgangskode godkendte G Suite-konti vil i nærmeste fremtid ophøre med at fungere.

Tjek hér, hvordan "Mindre sikre apps"aktiveres eller gå direkte til Indstillinger.

Benyttes flere Gmail-konti, så sørg for at ændre indstillingen "Mindre sikre apps" på de korrekte konti.

Bemærk, at man er nødt til at forlade "Mindre sikre apps"-indstillingsskærmen vha. Tilbage-pilen, for at effektuere indstillingen.

Benyttes denne metode, bør en stærk adgangskode anvendes til Gmail-kontoen (generelt altid er en god idé). Bemærk, at brug af standard IMAP-protokollen ikke i sig selv er mindre sikker.

Når "Mindre sikre apps" ikke er aktiveret, ses fejlen Godkendelse mislykkedes - ugyldige akkreditiver for konti (IMAP) og Brugernavn og adgangskode ikke accepteret for identiteter (SMTP).


Generelt

Muligvis ses advarslen "Log ind via din webbrowser". Dette sker, når Google anser det netværk, hvormed der forbindes til Internet (hvilket kan være et VPN), som ikke-sikkert. Dette kan forhindres vha. Gmails hurtig opsætningsguide eller en app-specifik adgangskode.

Tjek hér for Googles instruktioner, og hér for fejlfinding.


(7) Hvorfor vises sendte beskeder ikke (direkte) i Sendt-mappen?

Sendte beskeder flyttes normalt fra udbakken til Sendt-mappen, så snart udbyderen føjer sendte beskeder til Sendt-mappen. Dette kræver, at en Sendt-mappe vælges i kontoindstillingerne, og at Sendt-mappen ligeledes opsættes til synkronisering.

Visse udbydere holder ikke styr på sendte beskeder, eller den anvendte SMTP-server er muligvis ikke relateret til udbyderen. I så tilfælde tilføjer FairEmail automatisk sendte beskeder til Sendt-mappen under synkronisering af denne, hvilket vil ske, efter at en besked er afsendt. Bemærk, at dette vil forøge Internettrafikken.

Sker dette ikke, holder din udbyder muligvis ikke styr på sendte beskeder, eller der anvendes muligvis en ikke-udbyderrelateret SMTP-server. I så tilfælde kan man aktivere den avancerede identitetsindstilling Gem sendte beskeder for at lade FairEmail føje sendte beskeder til Sendt-mappen umiddelbart efter beskedafsendelsen. Bemærk, at aktivering af denne indstilling kan resultere i dubletbeskeder, hvis udbyderen også føjer sendte beskeder til Sendt-mappen. Bemærk også, at aktivering af indstillingen vil resultere i forøget datatrafik, især når der sendes beskeder med store vedhæftninger.

Hvis afsendte beskeder i udbakken ikke findes i Sendt-mappen ved en fuld synkronisering, flytes disse også fra udbakken til Sendt-mappen. En fuld synkronisering sker, når der genforbindes til serveren, eller ved periodisk eller manuel synkronisering. Der ønskes sandsynligvis i stedet at aktivere den avancerede indstilling Gem sendte beskeder for hurtigere at flytte beskeder til Sendt-mappen.


(8) Kan en Microsoft Exchange-konto benyttes?

En Microsoft Exchange-konto kan benyttes, såfremt den er tilgængelig via IMAP (er normalt tilfældet). Tjek hér for yderligere information.

Tjek hér for Microsoft-dokumentation vedr. opsætning af e-mail klient. Der er også et afsnit om almindelige forbindelsesfejl og løsninger.

Visse ældre Exchange-serverversioner har en fejl, der forårsager tomme beskeder og ødelagte vedhæftninger. Tjek denne FAQ for en løsning.

Tjek denne FAQ vedr. ActiveSync-understøttelse.

Tjek denne FAQ vedr. OAuth-understøttelse.


(9) Hvad er identiteter/hvordan tilføjes et alias?

Identiteter repræsenteres af e-mailadresser, du sender fra via en e-mailserver (SMTP).

Visse udbydere tillader brug af flere aliaser. Disse kan opsættes ved at indstille e-mailadressefeltet fra en ekstra identitet som aliasadressen og indstille brugernavnefeltet til hoved e-mailadresse.

Bemærk, at en identitet kan kopieres vha. et langt tryk på den.

Alternativt kan Tillad redigering af afsenderadresse aktiveres under Avancerede indstillinger for en eksisterende identitet for at redigere brugernavnet ved beskedoprettelsen, såfremt udbyderen tillader dette.

FairEmail opdaterer automatisk adgangskoder til relaterede identiteter, når adgangskoden til den tilknyttede konto/relateret identitet opdateres.

Tjek denne FAQ om redigering af brugernavnet til e-mailadresser.


(10) Hvad betyder 'UIDPLUS ikke understøttet'?

Fejlmeddelelsen *UIDPLUS ikke understøttet * betyder, at e-mailudbyderen ikke tilbyder IMAP UIDPLUS-udvidelsen. Denne IMAP-udvidelse kræves for at implementere tovejssynkronisering, der ikke er en valgfri funktion. Så medmindre udbyderen kan aktivere denne udvidelse, kan FairEmail ikke benytte med denne.


(11) Hvorfor er POP uunderstøttet?

Udover at enhver anstændig e-mail udbyder i dag understøtter IMAP, vil brug af POP resultere i unødvendig ekstra strømforbrug samt forsinkede notifikationer om nye beskeder. Desuden er POP uegnet til tovejssynkronisering, og oftere end ikke, læses og skrives der i dag beskeder på forskellige enheder.

Grundlæggende understøtter POP kun download og sletning af beskeder fra indbakken. Dvs., at almindelige operationer, såsom indstilling af besekedattributter (læst, stjernemarkeret, besvaret mv.), tilføjelse (sikkerhedskopiering) og flytning af beskeder ikke er mulige.

Tjek også, hvad Google skriver om det.

F.eks. kan Gmail importere beskeder fra en anden POP-konto, hvilket kan anvendes som en løsning, når en udbyder ikke understøtter IMAP.

tl;dr; overvej at skifte til IMAP.


(12) Hvordan fungerer kryptering/dekryptering?

Kommunikation med e-mailservere sker altid krypteret, medmindre dette eksplicit deaktiveres. Dette spørgsmål omhandler valgfri end-to-end kryptering med PGP eller S/MIME. Afsender og modtager bør først aftale dette og udveksle signerede beskeder for at overføre deres offentlige nøgler for at kunne sende krypterede beskeder.

Generelt

Tjek hér, hvordan kryptering vha. offentlige/private nøgler fungerer.

Kryptering kort fortalt:

  • Udgående beskeder krypteres vha. modtagerens offentlige nøgle
  • Indgående beskeder dekrypteres vha. modtagerens private nøgle

Signering kort fortalt:

  • Udgående beskeder signeres med afsenderens private nøgle
  • Indgående beskeder bekræftes vha. afsenderens offentlige nøgle

For at signere/kryptere en besked, vælg den passende metode i Send-dialogen. Er der tidliger valgt Vis ikke igen, kan Send-dialogen altid åbnes igen vha. trepunktsmenuen.

For at bekræfte en signatur eller dekryptere en modtaget besked, så åbn beskeden og tryk på gestus- eller hængelåsikonet umiddelbart under beskedhandlingsbjælken.

Første gang en signeret/krypteret besked sendes, anmodes der muligvis om en signeringsnøgle. Mhp. efterfølgende brug gemmer FairEmail automatisk den valgte signeringsnøgle i den anvendte identitet. Er der behov for at nulstille signeringsnøglen, så gem identiteten eller brug et langt tryk på identiteten på identitetslisten og vælg Nulstil signeringsnøgle. Den valgte signeringsnøgle er synlig på identitetslisten. Skal en nøgle kunne vælges fra gang til gang, kan flere identiteter oprettes for den samme konto med den samme e-mailadresse.

I fortrolighedsindstillingerne kan man vælge standardkrypteringsmetoden (PGP eller S/MIME), aktivere Signér som standard, Kryptér som standard samt Dekryptér automatisk beskeder. Vær dog opmærksom på, at automatisk dekryptering ikke er mulig, hvis brugerinteraktion kræves, såsom valg af en nøgle eller læsning af et sikkerhedstoken.

Beskedtekster/vedhæftninger, som skal krypteres, samt dekrypterede beskedtekster/vedhæftninger lagres kun lokalt og overføres aldrig til fjernservere. Vil man fortryde dekryptering, kan menupunktet Gensynk fra trepunktsmenuen på beskedhandlingsbjælken benyttes.

PGP

OpenKeychain skal først installeres og opsættes. FairEmail er aftestet med OpenKeychain version 5.4. Senere versioner er sansynligvis kompatible, men tidligere versioner er muligvis ikke.

Vigtigt: OpenKeychain-appen er kendt for at gå ned (upåagtet), når den kaldende app (FairEmail) endnu ikke er godkendt og er ved at få en eksisterende offentlig nøgle. Dette kan løse dette ved at prøve at sende en signeret/krypteret besked til en afsender med en ukendt offentlig nøgle.

Vigtigt: Kan OpenKeychain-appen ikke (længere) finde en nøgle, skal en tidligere valgt nøgle muligvis nulstilles. Dette kan gøres via et langt tryk på en identitet i identitetsoversigten (Opsætning, trin 2, Håndtér).

**Vigtigt **: For at lade apps såsom FairEmail pålideligt oprette forbindelse til OpenKeychain-tjenesten for at kryptere/dekryptere beskeder, kan deaktivering af batterioptimering for OpenKeychain-appen være nødvendigt.

Vigtigt: OpenKeychain-appen har angiveligt behov for kontakttilladelse for at fungere korrekt.

Vigtigt: På visse Android-versioner/-enheder er det nødvendigt at aktivere *Vis popups i baggrundstilstand * i de udvidede tilladelser til Android-app indstillingerne i OpenKeychain-appen. Uden denne tilladelse, gemmes udkastet, men OpenKeychain-popup'en til bekræftelse/valg vises muligvis ikke.

FairEmail vil sende Autocrypt-headeren til brug for andre e-mailklienter, men kun for signerede og krypterede beskeder, da for mange e-mailservere har problemer med denne ofte lange header. Bemærk, den mest sikre måde til start af en krypteret e-mailudveksling er ved først at sende signerede beskeder. Efter signaturbekræftelse eller beskeddekryptering sendes modtagne Autocrypt-headers til OpenKeychain-appen til opbevaring.

Al nøglehåndtering uddelegeres af sikkerhedsårsager til OpenKeychain-appen. FairEmail gemmer dermed ikke PGP-nøgler.

Inline-krypteret PGP i modtagne beskeder understøttes, men ikke inline PGP-signaturer/inline PGP i udgående beskeder. Tjek hér vedr. årsag.

Kun signerede/krypterede beskeder er ikke nogen god idé. Tjek her vedr. årsagen:

Kun signarede beskeder understøttes, men ikke kun krypterede ditto.

Almindelige fejl:

  • Ingen nøgle: Ingen PGP-nøgle tilgængelig for en af de angivne e-mailadresser
  • Manglende krypteringsnøgle: Der er sandsynligvis valgt en nøgle i FairEmail, der ikke længere forefindes i OpenKeychain-appen. Nulstilling af nøglen (se ovenfor) løser sandsynligvis dette problem.

S/MIME

Den/de offentlige modtagernøgle(r) kræves ved beskedkryptering. Den private nøgle kræves ved beskedsignering.

Private nøgler opbevares af Android og kan herfra importeres via avancerede sikkerhedsindstillinger. En genvejsknap til dette findes under fortrolighedsindstillingerne. Android anmoder om opsætning af PIN-kode, mønster eller adgangskode, hvis dette ikke allerede er gjort. Benyttes en Nokia-enhed med Android 9, så læs først dette.

Bemærk, at certifikater kan indeholde flere nøgler til flere formål, f.eks. til godkendelse, kryptering og signering. Android importerer kun den første nøgle, så for at importere alle nøgler, skal certifikatet først opdeles. Dette er ikke en almindeligt forekommende handling, så det anbefales at bede certifikatleverandøren om support.

Bemærk, at selvom S/MIME-signering med andre algoritmer end RSA understøttes, gælder dette måske ikke for andre e-mailklienter. S/MIME-kryptering er kun mulig med symmetriske algoritmer, hvilket i praksis betyder RSA-brug.

Standardkrypteringsmetoden er PGP, dog huskes den ssenest anvendte krypteringsmetode til næste gang for den valgte identitet. Det kan være nødvendigt igen at aktivere Send-valgmulighederne i trepriksmenuen for at kunne vælge krypteringsmetode.

For at tillade forskellige private nøgler til den samme e-mailadresse giver FairEmail altid mulighed for valg af en nøgle ved flere identiteter til den samme e-mailadresse for den samme konto.

Offentlige nøgler opbevares af FairEmail og kan importeres ifm. første bekræftelse af en signatur eller via fortrolighedsindstillingerne (PEM- eller DER-format).

FairEmail foretager bekræftelse af både signaturen samt den komplette certifikatkæde.

Almindelige fejl:

  • Intet certifikat fundet, der matcher targetContraints: Dette betyder sandsynligvis, at en gammel version af FairEmail benyttes
  • kunne ikke finde en gyldig certificeringssti til det anmodede mål: Dette betyder grundlæggende, at der ikke blev fundet en eller flere mellem- eller rodcertifikater
  • Privat nøgle matcher ikke nogle krypteringsnøgler: Den valgte nøgle kan ikke anvendes til beskeddekrypteringen, da den sandsynligvis ikke er den korrekte nøgle
  • Ingen privat nøgle: Intet certifikat er valgt eller intet certifikat var tilgængeligt i Android-nøglelageret

Er certifikatkæden forkert, kan man få vist alle certifikaterne ved tryk på den lille infoknap. Efter certifikatoplysninger vises udstederen eller "selfSign". Et certifikat er selvsigneret, når både emne og udsteder er identiske. Certifikater fra en certifikatmyndighed (CA) er markeret med "keyCertSign". Certifikater i Android-nøglelageret, er markeret med "Android".

En gyldig kæde ser således ud:

Dit certifikat > nul eller flere mellemliggende certifikater > CA (root) certifikat markeret med "Android"

Bemærk, at en certifikatkæde altid er ugyldig, hvis intet ankercertifikat findes i Android-nøglelageret, hvilket er fundamentalt for S/MIME-certifikatbekræftelse.

Tjek hér, hvordan certifikater kan importeres til Android-nøglelageret.

Brug af udløbne nøgler, inline-krypterede/signerede beskeder samt hardwaresikkerhedstokens er uunderstøttet.

Kigges der efter et gratis (test) S/MIME-certifikat, så tjek hér for muligheder. Husk føtst at læse dette ved anmodning om et S/MIME Actalis-certifikat. Kigges der efter et billigt S/MIME-certifikat, havde udvikleren en god oplevelse med Certum.

Sådan udpakkes en offentlig nøgle fra et S/MIME-certifikat:

openssl pkcs12 -in filenavn.pfx/p12 -clcerts -nokeys -out cert.pem

S/MIME-signaturer mv. kan afkodes hér.

S/MIME-signering/-kryptering er en Pro-funktion, mens alle øvrige PGP- og S/MIME-operationer er gratis i brug.


(13) Hvordan fungerer søgning på en enhed/server?

Beskedsøgning kan foretages efter Afsender (fra), Modtager (til, kopi, bcc), Emne, nøgleord eller beskedtekst via forstørrelsesglasset i en mappes handlingsbjælke. Søgning kan også ske fra enhver app ved at vælge *Søg efter e-mail * i popup-menuen kopiér/indsæt.

Søgning i den fælles indbakke udføres i alle mapper på alle konti, søgning i mappelisten udføres kun for den tilknyttede konto og søgning i en mappe udføres kun i dén mappe.

Beskedsøging sker indledningsvis på enheden. For at fortsætte søgningen på serveren, brug handlingsknappen nederst med ikonet Søg igen. Man kan vælge, i hvilken mappe søgningen skal fortsættes.

IMAP-protokollen understøtter kun søgning i én mappe ad gangen. Serversøgning er ressourcekrævende og derfor uden mulighed for valg af flere mapper.

Søgning i lokale beskeder er versal/minuskel ufølsom på deltekst. Lokale beskedtekster gennemsøges kun, såfremt selve beskedteksterne allerede er downloadet. Serversøgning kan være både versal/minuskel følsom eller ufølsom og kan, afhængigt af udbyderen, være på deltekst eller hele ord.

Visse servere kan ikke håndtere søgning i beskedtekster ifm. et stort beskedantal. For sådanne tilfælde findes en mulighed for at deaktivere søgning i beskedtekster.

Det er muligt at bruge Gmail-søgeoperatører vha. søgekommandopræfikset raw:. Er kun én Gmail-konto opsat, kan en raw søgning startes direkte på serveren ved at søge i den fælles indbakke. Er flere Gmail-konti opsat, skal man først gå til mappelisten eller arkivmappen (alle beskeder) for den Gmail-konto, der skal gennemsøges. Tjek hér ang. de mulige søgeoperatører. F.eks.:

raw:larger:10M

Gennemsøgning af et stort beskedantal på enheden sker ikke særligt hurtigt grundet to begrænsninger:

  • sqlite, Androids databasemotor har en poststørrelsesbegrænsning, der forhindrer, at beskedtekster gemmes i databasen
  • Android-apps får kun begrænset hukommelse at arbejde med, selv hvis enheden har masser af hukommelse til rådighed

Dette betyder, at søgning efter en beskedtekst i adskillige filer kræver, at disse filer åbnes/tjekkes én for én, hvilket er en relativt ressourcekrævende proces.

Under Diverse indstillinger kan Byg søgeindeks aktiveres for markant at øge søgehastigheden på enheden (øger dog samtidigt også både strøm- og lagerpladsforbrug). Søgeindekset er baseret på ord, så deltekstsøgning er ikke muligt. Søgning vha. søgeindekset er som standard OG (AND), så søgning efter f.eks. æble appelsin vil søge efter både æble OG appelsin. Ord adskilt med kommaer resulterer i en ELLER (OR) søgning, så f.eks. æble, appelsin vil søge efter enten æble ELLER appelsin. Begge kan kombineres, så søgning efter f.eks. æble, appelsin banan vil søge efter æble ELLER (appelsin OG banan). Brug af søgeindekset er en Pro-funktion.

Fra version 1.1315 er det muligt at benytte søgeudtryk såsom dette:

æble +banan-kirsebær?nødder

Dette vil resultere i en søgning som denne:

("æble" OG "banana" OG IKKE "kirsebær") ELLER "nødder"

Søgeudtryk kan benyttes til søgning på enheden via søgeindekset samt til søgning på e-mailserveren, men af ydelsesårsager ikke til søgning på enheden uden søgeindeks.

Søgning på enheden er en gratis funktion vha. søgeindekset, mens serversøgning er en Pro-funktion.


(14) Hvordan opsættes en Outlook-/Live-/Hotmail-konto?

En Outlook-/Live-/Hotmail-konto kan opsættes via hurtigopsætningsguiden ved at vælg Outlook.

Brug af tofaktorgodkendelse ifm. en Outlook-, Live- eller Hotmail-konto kræver oprettelse af en app-adgangskode. Tjek informationen hér.

Tjek Microsofts vejledning hér.

Tjek denne FAQ for opsætnig af en Office365-konto.


(15) Hvorfor genindlæses beskedteksten konstant?

Beskedhovede og -tekst hentes separat fra serveren. Beskedteksten i større beskeder forudindlæses ikke på takserede forbindelser, men hentes efter behov, når en besked udfoldes. Konstant genindlæsning af beskedteksten vil fortsætte, hvis der ikke er forbindelse til kontoen. Tjek også næste spørgsmål, eller hvorvidt andre operationer, såsom beskedsynkronisering, afvikles.

Man kan tjekke konto- og mappelisten for kontoen og mappetilstanden (se forklaringen om betydningen af ikonerne) og operationslisten, tilgængelig via hovednavigeringsmenuen, for afventende operationer (tjek denne FAQ for betydningen af operationerne).

Har FairEmail stoppet synk grundet forudgående konnektivitetsproblemer, så tjek denne FAQ. Synkronisering kan også gennemtvinges via trepriksmenuen.

I modtagelsesindstillingerne kan man indstille maksimalstørrelsen for automatisk besked-download på takserede forbindelser.

Mobilforbindelser er oftest takserede, hvilket også gælder visse Wi-Fi hotspots.


(16) Hvorfor synkroniseres beskeder ikke?

Mulige årsager til beskedsynkroniseringsfejl (sendte eller modtagne):

  • Konto eller mappe(r) er ikke opsat til at synkronisere
  • Der er indstillet for få synkroniseringsdage
  • Ingen tilgængelig Internetforbindelse
  • E-mailserveren er midlertidigt utilgængelig
  • Android har stoppet synkroniseringstjenesten

Tjek derfor dine konto- og mappeindstillinger, samt at konti/mapper er forbundet (tjek forklaringen i navigeringsmenuen om ikonernes betydning).

Er der evt. fejlmeddelelser, så tjek denne FAQ.

På enheder med en masse hukommelsehungrende apps, vil Android muligvis stoppe synk-tjenesten grundet ressourcemangel.

Visse Android-versioner stopper apps og tjenester for aggressivt. Tjek dette dedikerede websted samt dette Android-problem for yderligere information.

Deaktivering af batterioptimering (opsætningstrin 4) reducerer chancen for, at Android stopper synk-tjenesten.

Ved gentagne forbindelsesfejl pauser FairEmail synk i stadigt længere intervaller for ikke at dræne enhedens batteri. Dette beskrives i denne FAQ.


(17) Hvorfor fungerer manuel synk ikke?

Er menuen Synkronisér nu nedtonet, er der ingen forbindelse til kontoen.

Tjek foregående spørgsmål for yderligere info.


(18) Hvorfor ses beskedforhåndsvisning ikke altid?

Beskedforhåndsvisningen kan ikke vises, hvis beskedteksten endnu ikke er downloadet. Tjek også denne FAQ.


(19) Hvorfor er Pro-funktionerne så dyre?

Det rette spørgsmål er, "hvorfor er der så mange skatter og afgifter?":

  • Moms: 25 % (afhængigt af land)
  • Google-gebyr: 30 %
  • Inkomstskat: 50 %
  • Paypal-gebyr: 5-10 % afhængigt af land/beløb

Så dét, der er tilbage til udvikleren, er blot en brøkdel af købsprisen.

Bemærk, at det kun er nødvendigt at købe visse bekvemmeligheds og avancerede funktioner, hvilket betyder, at FairEmail grundlæggende kan bruges gratis.

Bemærk også, at de fleste gratis apps ikke ser ud til at være bæredygtige i længden, hvorimod FairEmail vedligeholdes og understøttes korrekt, samt at gratis apps kan have faldgruber, såsom læk af fortrolige oplysninger.

Der er arbejdet på FairEmail næsten dagligt i flere end to år, så prisen synes er mere end rimelig. Af samme årsag vil der heller ikke være rabatter.


(20) Kan man få refusion?

Hvis en købt Pro-funktion ikke fungerer som tilsigtet, og dette ikke skyldes et problem i de gratis funktioner, og problemet ikke kan løses rettidigt, så kan man få refusion. I alle øvrigee tilfælde gives ikke refusion. Under ingen omstændigheder er der refusionsmulighed for noget problem relateret til de gratis funktioner, da disse intet har kostet, og da de kan evalueres uden funktionsbegrænsninger. Jeg tager som sælger ansvar for at levere dét, der er blevet lovet, og jeg forventer, at du tager ansvar for at informere dig om, hvad du reelt køber.

(21) Hvordan aktiverer man notifikationslyset?

Før Android 8 Oreo: Der findes en avanceret indstilling i opsætningen til dette.

Android 8 Oreo og senere: Tjek hér, hvordan notifikationskanaler opsættes. Man kan vis knappen Standard kanal i appens notifikationsindstillinger gå til direkte til de relaterede Android-notifikationskanalindstillinger.

Bemærk, at apps ikke længere kan ændre notifikationsindstillinger, herunder indstillinger for notifikationslys, på Android 8 Oreo og senere.

Det er undertiden nødvendigt at deaktivere indstillingen Vis beskedforhåndsvisning i notifikationer eller at aktivere indstillingerne Vis kun notifikationer med en forhåndsvisningstekst for at omgå fejl i Android. Dette gælder muligvis også notifikationslyde samt -vibrationer.

Indstilling af lysfarve før Android 8 understøttes ikke og er ikke muligt på Android 8 og senere.


(22) Hvad betyder konto-/mappefejl ...?

For lettere at diagnosticere problemer, skjuler FairEmail ikke fejl (hvilket tilsvarende apps ofte gør).

FairEmail forsøger automatisk at genoprette forbindelse efter en udsættelse. Denne udsættelse (pause) fordobles efter hvert mislykket forsøg for at forhindre batteridræning samt at blive låst ude permanent.

Der er generelle såvel som specifikke fejl for Gmail-konti (se nedenfor).

Generelle fejl

Fejlen ... Godkendelse mislykkedes ... eller ... GODKENDELSE mislykkedes ... skyldes sandsynligvis forkert brugernavn/adgangskode. Visse udbydere forventer som brugernavn blot brugernavn og andre den fulde e-mail brugernavn@eksempel.dk. Benyttes kopiér/indsæt til angivelse af brugernavn/adgangskode, kan der muligvis medtages ikke-synlige tegn, hvilket også kan forårsage denne fejl. Visse adgangskodehåndteringer er også kendt for at gøre dette forkert. Brugernavnet kan være minuskel/versal sensitivt, så prøv med kun minuskler. Adgangskoden er oftest minuskel/versal sensitiv. Visse udbydere kræver brug af en app-adgangskode i stedet for kontoadgangskoden, så tjek din udbyders dokumentation. Der er nogle gange nødvendigt først at aktivere ekstern adgang (IMAP/SMTP) på udbyderens websted. Andre mulige årsager kan være, at kontoen er blokeret, eller at indlogning er administrativt begrænset på en eller anden måde, f.eks. ved kun at tillade indlogning fra bestemte netværk/IP-adresser.

Fejlen *... For mange fejlede godkendelsesforsøg ... *betyder sandsynligvis, at du bruger en Yahoo-kontoadgangskode i stedet for en app ditto. Tjek denne FAQ vedr. opsætning af en Yahoo-konto.

Meddelelsen ... + OK ... betyder sandsynligvis, at en POP3-port (normalt portnr. 995) anvendes til en IMAP-konto (normalt ellers portnr. 993).

Fejlene ... ugyldig hilsen ..., ... kræver gyldig adresse ... og ... Parameter til HELO overholder ikke RFC-syntaks ... kan sandsynligvis løses ved at ændre den avancerede identitetsindstilling Anvend lokal IP-adresse i stedet for værtsnavn.

Fejlen ... Kunne ikke oprette forbindelse til vært... betyder, at e-mailserverer ikke svarede inden for en rimelig tid (20 sekunder som standard). Dette indikerer i reglen Internetforbindelsesproblemer, muligvis forårsaget af en VPN- eller firewall-app. Ved virkelig langsomme e-milservere kan man forsøge at øge timeout for forbindelsen i FairEmails forbindelsesindstillinger.

Fejlen ... Forbindelse afvist ... betyder, at e-mailserveren, eller noget mellem denne og appen såsom en firewall, aktivt afviste forbindelsen.

Fejlen ... Netværk kan ikke nås ... betyder, at e-mailserveren ikke kunne nås via den aktuelle Internetforbindelse, f.eks. fordi Internettrafik er begrænset til lokal trafik alene.

Fejlen ... Vært er uopløst ..., "... Kan ikke opløse vært... eller ... Ingen adresse tilknyttet værtsnavn ... betyder, at adressen på e-mailserveren ikke kunne opløses til en IP-adresse. Dette kan skyldes et VPN, adblocking eller en utilgængelig/ikke korrekt fungerende (lokal) DNS-server.

Fejlen ... Software forårsagede forbindelsesafbrydelse ... betyder, at e-mailserveren, eller noget mellem FairEmail og denne, aktivt afsluttede en eksisterende forbindelse. Dette kan f. eks. ske, når tilslutningen mistes pludseligt. Et typisk eksempel er aktivering af Flytilstand.

Fejlene ... BYE, logger ud ..., *... Forbindelse nulstillet af peer ... * betyder, at e-mailserveren aktivt afsluttede en eksisterende forbindelse.

Fejlen ... Forbindelse lukket af peer ... kan skyldes en ikke-opdateret Exchange-server. Tjek hér for yderligere oplysninger.

Fejlene ... Læsefejl ..., ... Skrivefejl ..., ... Læsning fik timeout ..., ... Broken pipe ... betyder, at e-mailserveren ikke længere svarer eller en dårlig Internetforbindelse.

Fejlen ... Forbindelse droppet af server? ... betyder, at e-mailserveren uventet afsluttede forbindelsen. Dette sker af og til ved for mange forbindelser på for kort tid, eller ved brug af en forkert adgangskode for mange gange. I så tilfælde bør man sikre sig, at adgangskoden er korrekt, deaktivere modtagelse i modtagelsesindstillingerne i omkring 30 minutter og forsøge igen. Hvis nødvendigt, tjek denne FAQ om, hvordan forbindelsesantallet kan reduceres.

Fejlen ... Uventet afslutning af zlib-inputstrøm ... betyder, at ikke alle data blev modtaget, muligvis grundet en dårlig/afbrudt forbindelse.

Fejlen ... forbindelsesfejl ... kan indikere For mange samtidige forbindelser.

Advarslen ... Uunderstøttet kodning ... betyder, at beskedtegnsættet er ukendt eller uunderstøttet. FairEmail benytter generelt ISO-8859-1 (Latin1), hvilket som oftest resulterer i korrekt beskedvisning.

Tjek hér vedr. fejlene ... Ikke-betroet ... ikke i certifikat ..., * ... Ugyldigt sikkerhedscertifikat (Kan ikke bekræfte server) ...* eller ... Betroet anker til certificeringssti ikke fundet ...

Tjek hér vedr. fejlen *... Syntaktisk ugyldigt HELO-argument(er) ... *.

Tjek hér vedr. fejlen ... Handshake mislykkedes ....

Tjek hér ang. fejlbetydninger, såsom EHOSTUNREACH og ETIMEDOUT.

Mulige årsager:

  • Firewall eller router blokerer forbindelser til serveren
  • Værtsnavnet eller portnummeret er ugyldigt
  • Der er problemer med denne Internetforbindelse
  • Der er problemer med at opløse domænenavne (Yandex: Prøv at deaktivere privat DNS i Android-indstillingerne)
  • E-mailserveren nægeter at acceptere (eksterne) forbindelser
  • E-mai-serveren nægter at acceptere en besked, fordi den f.eks. er for stor eller indeholder uacceptable links
  • Der er for mange forbindelser til serveren, se også næste spørgsmål

Grundet spam, blokerer mange offentlige Wi-Fi netværk udgående e-mail. Dette kan af og til omgås ved brug af en alternativ SMTP-port. Tjek leverandørdokumentationen ang. brugbare portnumre.

Benyttes et VPN, kan VPN-udbyderen muligvis blokere forbindelsen ved for aggressive forsøg på spamblokering. Bemærk, at Google Fi også benytter et VPN.

Afsendelsesfejl

SMTP-servere kan af forskellige årsager afvise beskeder. For store beskeder og aktivering af en e-mailservers spamfilter er de hyppigste årsager.

  • Gmails størrelsesbegrænsning for vedhæftninger udgør 25 MB
  • Outlooks og Office 365' størrelsesbegrænsning for vedhæftninger udgør 20 MB
  • Yahoos størrelsesbegrænsning for vedhæftninger udgør 25 MB
  • For 554 5.7.1 Tjeneste utilgængelig; Klient vært xxx.xxx.xxx.xxx blokeret, tjek venligst hér
  • 501 Syntaksfejl - linje for lang er ofte forårsaget af brug af en lang Autocrypt-header
  • 503 5.5.0 Modtager allerede angivet betyder typisk, at en adresse bruges som både TO- og CC-adresse
  • 554 5.7.1 ... ikke tilladt at videresende betyder, at e-mailserveren ikke genkender brugernavnet/e-mailadressen. Dobbelttjek værtsnavn og brugernavn/e-mailadresse i identitetsindstillingerne.
  • 550 Spam besked afvist, da IP er listet af ... betyder, at e-mailserveren har afvist at afsende en besked fra den aktuelle (offentlige) netværksadresse, fordi den tidligere har være misbrugt til spamafsendelse. Prøv at aktivere flytilstand i 10 minutter for at få tildelt en ny netværksadresse.
  • 571 5.7.1 Besked indeholder spam eller virus eller afsender er blokeret ... betyder, at e-mailserveren betragtede en udgående besked som spam. Dette betyder sandsynligvis, at e-mailserverens spamfiltre er for strikse. Kontakt e-mailudbyderen for support vedr. dette.

Ønskes Gmail SMTP-serveren brugt mhp. at omgå et for strikst, udgående spamfilter eller til at forbedre beskedleveringen:

  • Bekræft din e-mailadresse hér (en computerbrowser skal bruges til dette)
  • Ændr identitetsindstillingerne på denne måde (opsætning, trin 2, tryk på Håndtéer, tryk på identitet):

  Username: brugers Gmail-adresse
  Password: en app-adgangskode
  Host: smtp.gmail.com
  Port: 465
  Encryption: SSL/TLS
  Reply to address: brugers e-mailaddresse (avanceret identititetsindstillinger)


Gmail fejl

Godkendelsen af Gmail-kontiopsætninger vha. hurtigguiden skal periodisk opfriskes via Android-kontohåndteringen. Dette kræver kontakt-/konto-tilladelser samt Internetforbindelse.

Fejlen ... Godkendelse mislykkedes... Konto ikke fundet ... betyder, at en tidligere godkendt Gmail-konto er blevet fjernet fra enheden.

Fejlene ... Godkendelse mislykkedes... Ingen token ... betyder, at Android-kontohåndteringen ikke kunne opfriske en Gmail-kontos godkendelse.

Fejlen ... Ugyldige akkreditiverer ... netværksfejl ... betyder, at Android-kontohåndteringen ikke kunne opfriske e Gmail-kontos godkendelse grundet Internetforbindelsesproblemer

Fejlen ... Godkendelse mislykkedes... Ugyldige akkreditiver ... kan være forårsaget af et kontoadgangskodskift eller ophævelse af nødvendige konto-/kontakttilladelser. Er kontoadgangskoden skiftet, så godkend ugen Google-kontoen i Android-kontoindstillingerne. Ved ophævede tilladelser kan hurtigopsætningsguiden til Gmail startes for at gentildele nødvendige tilladelser (kontoen behøves ikke opsat igen).

Fejlen ... ServiceDisabled ... kan skyldes indrullering i Avanceret Beskyttelsesprogram: "For at læse e-mail, skal Gmail benyttes. Google-kontoen kan ikke bruges med apps og tjenester, som kræver adgang til følsomme data som e-mails", tjek mere info hér.

Hvis i tvivl, så anmod om support.


(23) Hvorfor ses advarslen ... ?

Generelt

Avarsler er adviseringsmeddelelser sendt af e-mailservere.

For mange samtidige forbindelser eller Maksimalt antal forbindelser overskred

Denne advarsel sendes ved for mange samtidige mappeforbindelser til den samme e-mail-konto.

Mulige årsager:

  • Flere e-mailklienter er forbundet til den samme konto
  • Samme e-mailklient er forbundet flere gange til den samme konto
  • Tidligere forbindelser blev brat afsluttet, f.eks. ved en pludselig mistet Internetforbindelse

Vent først lidt for at se, om problemet løser sig selv, ellers:

  • Skift enten til periodisk tjek for beskeder i modtagelsesindstillingerne, hvilket resulterer i, at mapper åbnes én ad gangen
  • Eller indstil nogle mapper til polling i stedet for at synkronisation (langt tryk på mappen i mappelisten, redigér egenskaber)

En nem måde at opsætte periodisk tjek for beskeder for alle mapper undtagen indbakken er at bruge Anvend for alle ... i trepriksmenuen på mappelisten, og at markere de to nederste, avancerede afkrydsningsfelter.

Det maksimale antal samtidige mappeforbindelser til Gmail udgør 15, så der kan synkes maks. 15 mapper samtidigt på samtlige dine enheder. Derfor er Gmail-brugermapper som standard opsat til polling fremfor løbende synk. Om nødvendigt eller ønsket, kan dette ændres vha. langt tryk på en mappe i mappelisten og så vælge Redigér egenskaber. Tjek oplysningerne hér.

Ved brug af en Dovecot-server, bør indstillingen mail_max_userip_connections muligvis ændres.

Bemærk, at det vil tage e-mailserveren et stykke tid at opdage tabte forbindelser, hvilket betyder, at kun halvdelen af mappeforbindelserne reelt er tilgængelige. For Gmail vil det kun være 7 forbindelser.


(24) Hvad betyder gennemse beskeder på serveren?

Gennemse beskeder på serveren henter beskeder fra e-mailserveren i realtid, når slutningen af listen over synkede beskeder nås, også når mappen er indstillet til ikke at synke. Denne funktion kan deaktiveres under Avancerede kontoindstillinger.


(25) Hvorfor kan der ikke vælges/åbnes/gemmes et billede, vedhæftning eller fil?

Er et menupunkt til at vælge/åbne/gemme en fil deaktiveret (nedtonet), eller meddelelsen Lageradgangs-framework ikke tilgængelig ses, så er Android-standardkomponenten lLageradgangs-framework antageligvis ikke til stede. Dette kan skyldes, at den ikke er indeholdt i en tilpasset (og debloated) ROM.

Da FairEmail ikke anmoder ikke om lagerpladstilladelser, kræves denne framework for valg af filer og mapper. Ingen app, undtagen måske filhåndteringer målrettet Android 4.4 KitKat eller senere, bør anmode om lagerpladstilladelser, da dette giver adgang til alle filer.

The storage access framework is provided by the package com.android.documentsui, which is visible as Files app on some Android versions (notable OxygenOS).

You can enable the storage access framework (again) with this adb command:

pm install -k --user 0 com.android.documentsui

Alternatively, you might be able to enable the Files app again using the Android app settings.


(26) Can I help to translate FairEmail in my own language?

Yes, you can translate the texts of FairEmail in your own language on Crowdin. Registration is free.

If you would like your name or alias to be included in the list of contributors in About the app, please contact me.


(27) How can I distinguish between embedded and external images?

External image:

External image

Embedded image:

Embedded image

Broken image:

Broken image

Note that downloading external images from a remote server can be used to record you did see a message, which you likely don't want if the message is spam or malicious.


(28) How can I manage status bar notifications?

In the setup you'll find a button Manage notifications to directly navigate to the Android notifications settings for FairEmail.

On Android 8.0 Oreo and later you can manage the properties of the individual notification channels, for example to set a specific notification sound or to show notifications on the lock screen.

FairEmail has the following notification channels:

(29) How can I get new message notifications for other folders?

Just long press a folder, select Edit properties, and enable either Show in unified inbox or Notify new messages (available on Android 7 Nougat and later only) and tap Save.


(30) How can I use the provided quick settings?

There are quick settings (settings tiles) available to:

  • globalt aktivere/deaktivere synkronisering
  • vise antallet af nye beskeder og markere dem som set (ikke læst)

Quick settings require Android 7.0 Nougat or later. The usage of settings tiles is explained here.


(31) How can I use the provided shortcuts?

Genveje er tilgængelige for:

  • at skrive en ny besked til en favoritkontakt
  • at opsætte konti, identiteter mv.

Genveje kræver Android 7.1 Nougat+. Brug af genveje forklares hér.


(32) Hvordan tjekkes, om læsning af e-mails virkelig er sikkert?

Dette kan gøres med E-mail Fortrolighedstester.


(33) Hvorfor fungerer redigerede afsenderadresser ikke?

For at forhindre spam, accepterer de fleste udbydere kun bekræftede adresser ifm. afsendelse.

F.eks. ændrer Google beskedhoveder som dette for ikke-bekræftede adresser:

Fra: Nogen <somebody@example.org>
X-Google-Originale-Fra: Nogen <somebody+extra@example.org>

Dette betyder, at den redigerede afsenderadresse automatisk erstattes af en bekræftet adresse inden bekedafsendelsen.

Bemærk, at dette er uafhængigt af at modtage beskeder.


(34) Hvordan matches identiteter?

Identiteter matches efter konto. For indgående beskeder tjekkes adresserne for til, cc, bcc, fra og (X-)leveret/konvolut/originale-til (i nævnte rækkefølge), og for udgående beskeder (kladder, udbakke og sendt) tjekkes kun fra-adresserne. Matchende adresser har forrang ift. delvist matchende, undtagen leveret til-adresser.

Den matchede adresse vises som via i adresseafsnittet for modtagne beskeder (mellem beskedhovedet og -teksten).

Bemærk, at identiteter skal aktiveres for at tillade matchning, samt at identiteter på andre konti ikke tages i betragtning.

Matchning udføres kun én gang ved beskedmodtagelsen, så ændring af opsætningen ændrer ikke eksisterende beskeder. Lokale beskeder kan dog ryddes vha. langt tryk på en mappe i mappelisten og gensynke beskederne.

Det er muligt at opsætte en regex i identitetsindstillingerne til at matche en e-mailadresses brugernavn (delen før @-tegnet).

Bemærk, at domænenavnet (tekst/tegn efter @) altid skal være identisk med identitetens domænenavn.

Ønskes en fang-alle e-mailadresser match, er denne regex for det meste OK:

.*

Vil man matche e-mailadresserne til specielle formål, abc@eksemepel.dk og xyx@eksemepel.dk samt også gerne have en fallback e-mailadresse, hoved@eksemepel.dk, kan noget ala dette gøres:

  • Identity: abc@eksempel.dk; regex: (?i)abc
  • Identity: xyz@eksempel.dk; regex: (?i)xyz
  • Identity: hoved@eskempel.dk; regex: ^(?i)((?!abc|xyz).)*$

Matchede identiteter kan benyttes til beskedfarvekodning. Identitetsfarven har forrang over kontofarven. Brug af identitetsfarver er en Pro-funktion.


(35) Hvorfor skal man være forsigtig med at få vist billeder, vedhæftninger, originalbeskeder og åbne links?

Visning af fjernlagrede billeder (tjek også denne FAQ) samt åbning af links fortæller muligvis ikke kun afsenderen, at beskeden er set, men kan også lække modtagerens IP-adresse. Tjek også dette spørgsmål: Hvorfor et e-mail link er farligere end et websøgningslink?.

Åbning af vedhæftninger eller visning af en original besked kan muligvis indlæse eksternt indhold og eksekvere scripts, som f.eks. kan lække fortrolige data samt udgøre en generel sikkerhedsrisiko.

Bemærk, at dine kontakter, uden deres vidende, kan sende ondsindede beskeder, hvis de er blevet inficeret med malware.

FairEmail genformaterer beskeder, hvilket ændre deres udseende ift. originalen, men også afslører phishing-links.

Bemærk, at genformaterede beskeder ofte er mere læsbare end originalerne, da margerne er fjernet, og skrifttypefarver og -størrelser er standardiserede.

Gmail-appen viser som standard billeder ved at downloade disse via en Google-proxyserver. Da billederne downloades fra kildeserveren i realtid, er dette endnu mindre sikkert, da Google, uden nogen større gavn, også er involveret.

Som standard kan billeder og originale beskeder vises for betroede afsendere fra gang til gang ved at markere Spørg ikke igen om ....

Tjek hér, hvis standarden for Åbn med apps ønskes nulstillet.


(36) Hvordan krypteres indstillingsfiler?

Kort svar: AES 256 bit

Langt svar:

  • 256 bit-nøglen genereres med PBKDF2WithHmacSHA1 vha. en 128 bit sikker, tilfældigt salt og 65.536 iterationer
  • Cipher'en er AES/CBC/PKCS5Padding

(37) Hvordan lagres adgangskoder?

Alle understøttede Android-versioner krypterer alle brugerdata, så alle data, inkl. brugernavne, adgangskoder, beskeder mv., lagres krypteret.

Er enheden sikret med PIN-kode, mønster eller adgangskode, kan konto- og identitetsadgangskoder gøres. synlige. Er dette er et problem, da enheden deles med andre, så overvej at anvende brugerprofiler.


(39) Hvordan kan FairEmails batteriforbrug reduceres?

Som standard viser nyere Android-versioner app-brug som en procentdel på Android-batteriindstillingssiden. Forvirrende nok er app-brug ikke det samme som batteriforbrug og er ikke engang direkte relateret til batteriforbrug! App-brugen (mens i brug) vil være meget høj, da FairEmail bruger en forgrundstjeneste, der af Android betragtes som konstant app-brug. Dette betyder dog ikke, at FairEmail konstant forbruger strøm. Det reelle stømforbrug kan ses ved at gå til denne skærm:

Android-indstillinger, Batteri, trepriksmenu Batteriforbrug, trepriksmenu Vis fuld enhedsbrug

Som en tommelfingerregel skal strømforbruget være under eller i hvert fald ikke meget højere end for Mobilnetværks-standby. If this isn't the case, please turn on Auto optimize in the receive settings. If this doesn't help, please ask for support.

It is inevitable that synchronizing messages will use battery power because it requires network access and accessing the messages database.

If you are comparing the battery usage of FairEmail with another email client, please make sure the other email client is setup similarly. For example comparing always sync (push messages) and (infrequent) periodic checking for new messages is not a fair comparison.

Reconnecting to an email server will use extra battery power, so an unstable internet connection will result in extra battery usage. Also, some email servers prematurely terminate idle connections, while the standard says that an idle connection should be kept open for 29 minutes. In these cases you might want to synchronize periodically, for example each hour, instead of continuously. Note that polling frequently (more than every 30-60 minutes) will likely use more battery power than synchronizing always because connecting to the server and comparing the local and remote messages are expensive operations.

On some devices it is necessary to disable battery optimizations (setup step 4) to keep connections to email servers open. In fact, leaving battery optimizations enabled can result in extra battery usage for all devices, even though this sounds contradictory!

Most of the battery usage, not considering viewing messages, is due to synchronization (receiving and sending) of messages. So, to reduce the battery usage, set the number of days to synchronize message for to a lower value, especially if there are a lot of recent messages in a folder. Long press a folder name in the folders list and select Edit properties to access this setting.

If you have at least once a day internet connectivity, it is sufficient to synchronize messages just for one day.

Note that you can set the number of days to keep messages for to a higher number than to synchronize messages for. You could for example initially synchronize messages for a large number of days and after this has been completed reduce the number of days to synchronize messages for, but leave the number of days to keep messages for. After decreasing the number of days to keep messages for, you might want to run the cleanup in the miscellaneous settings to remove old files.

In the receive settings you can enable to always synchronize starred messages, which will allow you to keep older messages around while synchronizing messages for a limited number of days.

Disabling the folder option Automatically download message texts and attachments will result in less network traffic and thus less battery usage. You could disable this option for example for the sent folder and the archive.

Synchronizing messages at night is mostly not useful, so you can save on battery usage by not synchronizing at night. In the settings you can select a schedule for message synchronization (this is a pro feature).

FairEmail will by default synchronize the folder list on each connection. Since folders are mostly not created, renamed and deleted very often, you can save some network and battery usage by disabling this in the receive settings.

FairEmail will by default check if old messages were deleted from the server on each connection. If you don't mind that old messages that were delete from the server are still visible in FairEmail, you can save some network and battery usage by disabling this in the receive settings.

Some providers don't follow the IMAP standard and don't keep connections open long enough, forcing FairEmail to reconnect often, causing extra battery usage. You can inspect the Log via the main navigation menu to check if there are frequent reconnects (connection closed/reset, read/write error/timeout, etc). You can workaround this by lowering the keep-alive interval in the advanced account settings to for example 9 or 15 minutes. Note that battery optimizations need to be disabled in setup step 4 to reliably keep connections alive.

Some providers send every two minutes something like 'Still here' resulting in network traffic and your device to wake up and causing unnecessary extra battery usage. You can inspect the Log via the main navigation menu to check if your provider is doing this. If your provider is using Dovecot as IMAP server, you could ask your provider to change the imap_idle_notify_interval setting to a higher value or better yet, to disable this. If your provider is not able or willing to change/disable this, you should consider to switch to periodically instead of continuous synchronization. You can change this in the receive settings.

If you got the message This provider does not support push messages while configuring an account, consider switching to a modern provider which supports push messages (IMAP IDLE) to reduce battery usage.

If your device has an AMOLED screen, you can save battery usage while viewing messages by switching to the black theme.

If auto optimize in the receive settings is enabled, an account will automatically be switched to periodically checking for new messages when the email server:

  • Sender et 'Stadig her' inden for 3 minutter
  • E-mailserveren understøtter ikke push-beskeder
  • Keep-alive intervallet er kortere end 12 minutes

In addition, the trash and spam folders will be automatically set to checking for new messages after three successive too many simultaneous connections errors.


(40) How can I reduce the data usage of FairEmail?

You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.

It is inevitable that data will be used to synchronize messages.

If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).

To reduce data usage, you could change these advanced receive settings:

  • Tjek, om gamle beskeder er fjernet fra serveren
  • Synkronisér (delte) mappelister: Deaktivér

By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.


(41) How can I fix the error 'Handshake failed' ?

There are several possible causes, so please read to the end of this answer.

The error 'Handshake failed ... WRONG_VERSION_NUMBER ...' might mean that you are trying to connect to an IMAP or SMTP server without an encrypted connection, typically using port 143 (IMAP) and port 25 (SMTP), or that a wrong protocol (SSL/TLS or STARTTLS) is being used.

Most providers provide encrypted connections using different ports, typically port 993 (IMAP) and port 465/587 (SMTP).

If your provider doesn't support encrypted connections, you should ask to make this possible. If this isn't an option, you could enable Allow insecure connections both in the advanced settings AND the account/identity settings.

See also this FAQ.

Fejlen 'Handshake mislykkedes ... SSLV3_ALERT_ILLEGAL_PARAMETER ...' is either caused by a bug in the SSL protocol implementation or by a too short DH key on the email server and can unfortunately not be fixed by FairEmail.

Fejlen 'Handshake mislykkedes ... HANDSHAKE_FAILURE_ON_CLIENT_HELLO ...' might be caused by the provider still using RC4, which isn't supported since Android 7 anymore.

The error 'Handshake failed ... UNSUPPORTED_PROTOCOL or TLSV1_ALERT_PROTOCOL_VERSION ...' might be caused by enabling hardening connections in the connection settings or by Android not supporting older protocols anymore, like SSLv3.

Android 8 Oreo and later do not support SSLv3 anymore. There is no way to workaround lacking RC4 and SSLv3 support because it has completely been removed from Android (which should say something).

You can use this website or this website to check for SSL/TLS problems of email servers.


(42) Can you add a new provider to the list of providers?

If the provider is used by more than a few people, yes, with pleasure.

The following information is needed:

<provider
    name="Gmail"
    link="https://support.google.com/mail/answer/7126229" // link to the instructions of the provider
    type="com.google"> // dette kræves ikke
    <imap
        host="imap.gmail.com"
        port="993"
        starttls="false" />
    <smtp
        host="smtp.gmail.com"
        port="465"
        starttls="false" />
</provider>

The EFF writes: "Additionally, even if you configure STARTTLS perfectly and use a valid certificate, there’s still no guarantee your communication will be encrypted."

So, pure SSL connections are safer than using STARTTLS and therefore preferred.

Please make sure receiving and sending messages works properly before contacting me to add a provider.

See below about how to contact me.


(43) Can you show the original ... ?

Show original, shows the original message as the sender has sent it, including original fonts, colors, margins, etc. FairEmail does and will not alter this in any way, except for requesting TEXT_AUTOSIZING, which will attempt to make small text more readable.


(44) Can you show contact photos / identicons in the sent folder?

Contact photos and identicons are always shown for the sender because this is necessary for conversation threads. Getting contact photos for both the sender and receiver is not really an option because getting contact photo is an expensive operation.


(45) How can I fix 'This key is not available. To use it, you must import it as one of your own!' ?

You'll get the message This key is not available. To use it, you must import it as one of your own! when trying to decrypt a message with a public key. To fix this you'll need to import the private key.


(46) Why does the message list keep refreshing?

If you see a 'spinner' at the top of the message list, the folder is still being synchronized with the remote server. You can see the progress of the synchronization in the folder list. See the legend about what the icons and numbers mean.

The speed of your device and internet connection and the number of days to synchronize messages for determine how long synchronization will take. Note that you shouldn't set the number of days to synchronize messages for to more than one day in most cases, see also this FAQ.


(47) How do I solve the error 'No primary account or no drafts folder' ?

You'll get the error message No primary account or no drafts folder when trying to compose a message while there is no account set to be the primary account or when there is no drafts folder selected for the primary account. This can happen for example when you start FairEmail to compose a message from another app. FairEmail needs to know where to store the draft, so you'll need to select one account to be the primary account and/or you'll need to select a drafts folder for the primary account.

This can also happen when you try to reply to a message or to forward a message from an account with no drafts folder while there is no primary account or when the primary account does not have a drafts folder.

Please see this FAQ for some more information.


(48) How do I solve the error 'No primary account or no archive folder' ?

You'll get the error message No primary account or no archive folder when searching for messages from another app. FairEmail needs to know where to search, so you'll need to select one account to be the primary account and/or you'll need to select a archive folder for the primary account.


(49) How do I fix 'An outdated app sent a file path instead of a file stream' ?

You likely selected or sent an attachment or image with an outdated file manager or an outdated app which assumes all apps still have storage permissions. For security and privacy reasons modern apps like FairEmail have no full access to all files anymore. This can result into the error message An outdated app sent a file path instead of a file stream if a file name instead of a file stream is being shared with FairEmail because FairEmail cannot randomly open files.

You can fix this by switching to an up-to-date file manager or an app designed for recent Android versions. Alternatively, you can grant FairEmail read access to the storage space on your device in the Android app settings. Note that this workaround won't work on Android Q anymore.

See also question 25 and what Google writes about it.


(50) Can you add an option to synchronize all messages?

You can synchronize more or even all messages by long pressing a folder (inbox) in the folder list of an account (tap on the account name in the navigation menu) and selecting Synchronize more in the popup menu.


(51) How are folders sorted?

Folders are first sorted on account order (by default on account name) and within an account with special, system folders on top, followed by folders set to synchronize. Within each category the folders are sorted on (display) name. You can set the display name by long pressing a folder in the folder list and selecting Edit properties.

The navigation (hamburger) menu item Order folders in the setup can be used to manually order the folders.


(52) Why does it take some time to reconnect to an account?

There is no reliable way to know if an account connection was terminated gracefully or forcefully. Trying to reconnect to an account while the account connection was terminated forcefully too often can result in problems like too many simultaneous connections or even the account being blocked. To prevent such problems, FairEmail waits 90 seconds until trying to reconnect again.

You can long press Settings in the navigation menu to reconnect immediately.


(53) Can you stick the message action bar to the top/bottom?

The message action bar works on a single message and the bottom action bar works on all the messages in the conversation. Since there is often more than one message in a conversation, this is not possible. Moreover, there are quite some message specific actions, like forwarding.

Moving the message action bar to the bottom of the message is visually not appealing because there is already a conversation action bar at the bottom of the screen.

Note that there are not many, if any, email apps that display a conversation as a list of expandable messages. This has a lot of advantages, but the also causes the need for message specific actions.


(54) How do I use a namespace prefix?

A namespace prefix is used to automatically remove the prefix providers sometimes add to folder names.

For example the Gmail spam folder is called:

[Gmail]/Spam

By setting the namespace prefix to [Gmail] FairEmail will automatically remove [Gmail]/ from all folder names.


(55) How can I mark all messages as read / move or delete all messages?

You can use multiple select for this. Long press the first message, don't lift your finger and slide down to the last message. Then use the three dot action button to execute the desired action.


(56) Can you add support for JMAP?

There are almost no providers offering the JMAP protocol, so it is not worth a lot of effort to add support for this to FairEmail.


(57) Can I use HTML in signatures?

Yes, you can use HTML. In the signature editor you can switch to HTML mode via the three-dots menu.

Note that if you switch back to the text editor that not all HTML might be rendered as-is because the Android text editor is not able to render all HTML. Similarly, if you use the text editor, the HTML might be altered in unexpected ways.

If you want to use preformatted text, like ASCII art, you should wrap the text in a pre element, like this:

<pre>
  |\_/|
 / @ @ \
( > º < )
 `>>x<<´
 /  O  \
 </pre>

(58) What does an open/closed email icon mean?

The email icon in the folder list can be open (outlined) or closed (solid):

External image

Message bodies and attachments are not downloaded by default.

External image

Message bodies and attachments are downloaded by default.


(59) Can original messages be opened in the browser?

For security reasons the files with the original message texts are not accessible to other apps, so this is not possible. In theory the Storage Access Framework could be used to share these files, but even Google's Chrome cannot handle this.


(60) Did you know ... ?

  • Vidste du, at stjernemarkerede beskeder kan synkroniseres/beholdes for altid? (dette kan aktiveres i modtagelsesindstillingerne)
  • Vidste du, at du et langt tryk på ikonet 'Skriv besked' tager dig til Udkast-mappen?
  • Vidste du, at der er en avanceret mulighed for at markere beskeder som læst, når de flyttes? (arkivering og kassering er også i flytning)
  • Vidste du, at du kan vælge tekst (eller en e-mailadresse) i en app i de seneste Android-versioner og lade FairEmail søge efter den?

  • Vidste du, at man med et lang tryk på fuldskærmsikonet kan få vist originalbeskedteksten?

(61) Why are some messages shown dimmed?

Messages shown dimmed (grayed) are locally moved messages for which the move is not confirmed by the server yet. This can happen when there is no connection to the server or the account (yet). These messages will be synchronized after a connection to the server and the account has been made or, if this never happens, will be deleted if they are too old to be synchronized.

You might need to manually synchronize the folder, for example by pulling down.

You can view these messages, but you cannot move these messages again until the previous move has been confirmed.

Pending operations are shown in the operations view accessible from the main navigation menu.


(62) Which authentication methods are supported?

The following authentication methods are supported and used in this order:

  • LOGIN
  • PLAIN
  • CRAM-MD5
  • XOAUTH2 (Gmail, Yandex)
  • NTLM (ikke-testet)

SASL authentication methods, besides CRAM-MD5, are not supported because JavaMail for Android does not support SASL authentication.

If your provider requires an unsupported authentication method, you'll likely get the error message authentication failed.

Server Name Indication is supported by all supported Android versions.


(63) How are images resized for displaying on screens?

Large inline or attached PNG and JPEG images will automatically be resized for displaying on screens. This is because email messages are limited in size, depending on the provider mostly between 10 and 50 MB. Images will by default be resized to a maximum width and height of about 1440 pixels and saved with a compression ratio of 90 %. Images are scaled down using whole number factors to reduce memory usage and to retain image quality. Automatically resizing of inline and/or attached images and the maximum target image size can be configured in the send settings.

If you want to resize images on a case-by-case basis, you can use Send Reduced or a similar app.


(64) Can you add custom actions for swipe left/right?

The most natural thing to do when swiping a list entry left or right is to remove the entry from the list. The most natural action in the context of an email app is moving the message out of the folder to another folder. You can select the folder to move to in the account settings.

Other actions, like marking messages read and snoozing messages are available via multiple selection. You can long press a message to start multiple selection. See also this question.

Swiping left or right to mark a message read or unread is unnatural because the message first goes away and later comes back in a different shape. Note that there is an advanced option to mark messages automatically read on moving, which is in most cases a perfect replacement for the sequence mark read and move to some folder. You can also mark messages read from new message notifications.

If you want to read a message later, you can hide it until a specific time by using the snooze menu.


(65) Why are some attachments shown dimmed?

Inline (image) attachments are shown dimmed. Inline attachments are supposed to be downloaded and shown automatically, but since FairEmail doesn't always download attachments automatically, see also this FAQ, FairEmail shows all attachment types. To distinguish inline and regular attachments, inline attachments are shown dimmed.


(66) Is FairEmail available in the Google Play Family Library?

The price of the few pro features is too low, lower than the price of most similar apps, and there are too many fees and taxes, to justify making FairEmail available in the Google Play Family Library. Note that Google promotes the Family libray, but lets developers pay for it.


(67) How can I snooze conversations?

Multiple select one of more conversations (long press to start multiple selecting), tap the three dot button and select Snooze .... Alternatively, in the expanded message view use Snooze ... in the message three-dots 'more' menu or the timelapse action in the bottom action bar. Select the time the conversation(s) should snooze and confirm by tapping OK. The conversations will be hidden for the selected time and shown again afterwards. You will receive a new message notification as reminder.

It is also possible to snooze messages with a rule.

You can show snoozed messages by unchecking Filter out > Hidden in the three dot overflow menu.

You can tap on the small snooze icon to see until when a conversation is snoozed.

By selecting a zero snooze duration you can cancel snoozing.


(68) Why can Adobe Acrobat reader not open PDF attachments / Microsoft apps not open attached documents?

Adobe Acrobat reader and Microsoft apps still expects full access to all stored files, while apps should use the Storage Access Framework since Android KitKat (2013) to have access to actively shared files only. This is for privacy and security reasons.

You can workaround this by saving the attachment and opening it from the Adobe Acrobat reader / Microsoft app, but you are advised to install an up-to-date and preferably open source PDF reader / document viewer, for example one listed here.


(69) Can you add auto scroll up on new message?

The message list is automatically scrolled up when navigating from a new message notification or after a manual refresh. Always automatically scrolling up on arrival of new messages would interfere with your own scrolling, but if you like you can enable this in the settings.


(70) When will messages be auto expanded?

When navigation to a conversation one message will be expanded if:

  • Der er kun én besked i konversationen
  • Der kun er én ulæst besked i konversationen

There is one exception: the message was not downloaded yet and the message is too large to download automatically on a metered (mobile) connection. You can set or disable the maximum message size on the 'connection' settings tab.

Duplicate (archived) messages, trashed messages and draft messages are not counted.

Messages will automatically be marked read on expanding, unless this was disabled in the individual account settings.


(71) How do I use filter rules?

You can edit filter rules by long pressing a folder in the folder list of an account (tap the account name in the navigation/side menu).

New rules will be applied to new messages received in the folder, not to existing messages. You can check the rule and apply the rule to existing messages or, alternatively, long press the rule in the rule list and select Execute now.

You'll need to give a rule a name and you'll need to define the order in which a rule should be executed relative to other rules.

You can disable a rule and you can stop processing other rules after a rule has been executed.

The following rule conditions are available:

  • Afsender indeholder
  • Modtager indeholder
  • Emne indeholder
  • Har vedhæftninger
  • Header indeholder
  • Dag/tidspunkt mellem

All the conditions of a rule need to be true for the rule action to be executed. All conditions are optional, but there needs to be at least one condition, to prevent matching all messages. If you want to match all senders or all recipients, you can just use the @ character as condition because all email addresses will contain this character.

Note that email addresses are formatted like this:

"Somebody" <somebody@example.org>

You can use multiple rules, possibly with a stop processing, for an or or a not condition.

Matching is not case sensitive, unless you use regular expressions. Please see here for the documentation of Java regular expressions. You can test a regex here.

Note that a regular expression supports an or operator, so if you want to match multiple senders, you can do this:

.*alice@example\.org.*|.*bob@example\.org.*|.*carol@example\.org.*

Note that dot all mode is enabled to be able to match unfolded headers.

You can select one of these actions to apply to matching messages:

  • Ingen handling (nyttigt for ikke)
  • Markér som læst
  • Markér som ulæst
  • Skjul
  • Undertryk notifikationer
  • Slumre
  • Tilføj stjerne
  • Angiv vigtighed (lokal prioritet)
  • Tilføj stikord
  • Flyt
  • Kopiér (Gmail: Etiket)
  • Besvar/videresend (med skabelon)
  • Tekst-til-tale (afsender og emne)
  • Automatisering (Tasker mv.)

Rules are applied directly after the message header has been fetched, but before the message text has been downloaded, so it is not possible to apply conditions to the message text. Note that large message texts are downloaded on demand on a metered connection to save on data usage.

If you want to forward a message, consider to use the move action instead. This will be more reliable than forwarding as well because forwarded messages might be considered as spam.

Since message headers are not downloaded and stored by default to save on battery and data usage and to save storage space it is not possible to preview which messages would match a header rule condition.

Some common header conditions (regex):

  • .*Auto-Submitted:.* RFC3834
  • .*Content Type: multipart/report.* RFC3462

In the three-dots more message menu there is an item to create a rule for a received message with the most common conditions filled in.

The POP3 protocol does not support setting keywords and moving or copying messages.

Using rules is a pro feature.


(72) What are primary accounts/identities?

The primary account is used when the account is ambiguous, for example when starting a new draft from the unified inbox.

Similarly, the primary identity of an account is used when the identity is ambiguous.

There can be just one primary account and there can be just one primary identity per account.


(73) Is moving messages across accounts safe/efficient?

Moving messages across accounts is safe because the raw, original messages will be downloaded and moved and because the source messages will be deleted only after the target messages have been added

Batch moving messages across accounts is efficient if both the source folder and target folder are set to synchronize, else FairEmail needs to connect to the folder(s) for each message.


(74) Why do I see duplicate messages?

Some providers, notably Gmail, list all messages in all folders, except trashed messages, in the archive (all messages) folder too. FairEmail shows all these messages in a non obtrusive way to indicate that these messages are in fact the same message.

Gmail allows one message to have multiple labels, which are presented to FairEmail as folders. This means that messages with multiple labels will be shown multiple times as well.


(75) Can you make an iOS, Windows, Linux, etc version?

A lot of knowledge and experience is required to successfully develop an app for a specific platform, which is why I develop apps for Android only.


(76) What does 'Clear local messages' do?

The folder menu Clear local messages removes messages from the device which are present on the server too. It does not delete messages from the server. This can be useful after changing the folder settings to not download the message content (text and attachments), for example to save space.


(77) Why are messages sometimes shown with a small delay?

Depending on the speed of your device (processor speed and maybe even more memory speed) messages might be displayed with a small delay. FairEmail is designed to dynamically handle a large number of messages without running out of memory. This means that messages needs to be read from a database and that this database needs to be watched for changes, both of which might cause small delays.

Some convenience features, like grouping messages to display conversation threads and determining the previous/next message, take a little extra time. Note that there is no the next message because in the meantime a new message might have been arrived.

When comparing the speed of FairEmail with similar apps this should be part of the comparison. It is easy to write a similar, faster app which just displays a lineair list of messages while possible using too much memory, but it is not so easy to properly manage resource usage and to offer more advanced features like conversation threading.

FairEmail is based on the state-of-the-art Android architecture components, so there is little room for performance improvements.


(78) How do I use schedules?

In the receive settings you can enable scheduling and set a time period and the days of the week when messages should be received. Note that an end time equal to or earlier than the start time is considered to be 24 hours later.

Automation, see below, can be used for more advanced schedules, like for example multiple synchronization periods per day or different synchronization periods for different days.

It is possible to install FairEmail in multiple user profiles, for example a personal and a work profile, and to configure FairEmail differently in each profile, which is another possibility to have different synchronization schedules and to synchronize a different set of accounts.

It is also possible to create filter rules with a time condition and to snooze messages until the end time of the time condition. This way it is possible to snooze business related messages until the start of the business hours. This also means that the messages will be on your device for when there is (temporarily) no internet connection.

Note that recent Android versions allow overriding DND (Do Not Disturb) per notification channel and per app, which could be used to (not) silence specific (business) notifications. Please see here for more information.

For more complex schemes you could set one or more accounts to manual synchronization and send this command to FairEmail to check for new messages:

(adb shell) am startservice -a eu.faircode.email.POLL

For a specific account:

(adb shell) am startservice -a eu.faircode.email.POLL --es account Gmail

You can also automate turning receiving messages on and off by sending these commands to FairEmail:

(adb shell) am startservice -a eu.faircode.email.ENABLE
(adb shell) am startservice -a eu.faircode.email.DISABLE

To enable/disable a specific account:

(adb shell) am startservice -a eu.faircode.email.ENABLE --es account Gmail
(adb shell) am startservice -a eu.faircode.email.DISABLE --es account Gmail

Note that disabling an account will hide the account and all associated folders and messages.

You can automatically send commands with for example Tasker:

Ny opgave: En genkendelig
Handlingskategori: Div./Send-
hensigtshandling: eu.faircode.email.ENABLE
Mål: Tjeneste

To enable/disable an account with the name Gmail:

Ekstra: konto:Gmail

Account names are case sensitive.

Scheduling is a pro feature.


(79) How do I use synchronize on demand (manual)?

Normally, FairEmail maintains a connection to the configured email servers whenever possible to receive messages in real-time. If you don't want this, for example to be not disturbed or to save on battery usage, just disable receiving in the receive settings. This will stop the background service which takes care of automatic synchronization and will remove the associated status bar notification.

You can also enable Synchronize manually in the advanced account settings if you want to manually synchronize specific accounts only.

You can use pull-down-to-refresh in a message list or use the folder menu Synchronize now to manually synchronize messages.

If you want to synchronize some or all folders of an account manually, just disable synchronization for the folders (but not of the account).

You'll likely want to disabled browse on server too.


(80) How do I fix the error 'Unable to load BODYSTRUCTURE' ?

The error message Unable to load BODYSTRUCTURE is caused by bugs in the email server, see here for more details.

FairEmail already tries to workaround these bugs, but if this fail you'll need to ask for support from your provider.


(81) Can you make the background of the original message dark in the dark theme?

The original message is shown as the sender has sent it, including all colors. Changing the background color would not only make the original view not original anymore, it can also result in unreadable messages.


(82) What is a tracking image?

Please see here about what a tracking image exactly is. In short tracking images keep track if you opened a message.

FairEmail will in most cases automatically recognize tracking images and replace them by this icon:

External image

Automatic recognition of tracking images can be disabled in the privacy settings.


(84) What are local contacts for?

Local contact information is based on names and addresses found in incoming and outgoing messages.

The main use of the local contacts storage is to offer auto completion when no contacts permission has been granted to FairEmail.

Another use is to generate shortcuts on recent Android versions to quickly send a message to frequently contacted people. This is also why the number of times contacted and the last time contacted is being recorded and why you can make a contact a favorite or exclude it from favorites by long pressing it.

The list of contacts is sorted on number of times contacted and the last time contacted.

By default only names and addresses to whom you send messages to will be recorded. You can change this in the send settings.


(85) Why is an identity not available?

An identity is available for sending a new message or replying or forwarding an existing message only if:

  • identiteten er opsat til synkronisering (afsendte beskeder)
  • den tilknyttede konto er opsat til synkronisering (modtagne beskeder)
  • den tilknyttede konto har en udkastmappe

FairEmail will try to select the best identity based on the to address of the message replied to / being forwarded.


(86) What are 'extra privacy features'?

The advanced option extra privacy features enables:

  • Opslag af ejeren af IP-adressen for et link
  • Detektering og fjernelse af sporingsbilleder

(87) What does 'invalid credentials' mean?

The error message invalid credentials means either that the user name and/or password is incorrect, for example because the password was changed or expired, or that the account authorization has expired.

If the password is incorrect/expired, you will have to update the password in the account and/or identity settings.

If the account authorization has expired, you will have to select the account again. You will likely need to save the associated identity again as well.


(88) How can I use a Yahoo, AOL or Sky account?

The preferred way to set up a Yahoo account is by using the quick setup wizard, which will use OAuth instead of a password and is therefore safer (and easier as well).

To authorize a Yahoo, AOL, or Sky account you will need to create an app password. For instructions, please see here:

Please see this FAQ about OAuth support.

Note that Yahoo, AOL, and Sky do not support standard push messages. The Yahoo email app uses a proprietary, undocumented protocol for push messages.

Push messages require IMAP IDLE and the Yahoo email server does not report IDLE as capability:

Y1-EVNE
* MULIGHED FOR IMAP4rev1 ID FLYT NAVNEOMRÅDE XYMHIGHESTMODSEQ UIDPLUS LITERAL+ CHILDREN X-MSG-EXT AFMARKÉR OBJEKTID
Y1 OK MULIGHED fuldført

(89) How can I send plain text only messages?

By default FairEmail sends each message both as plain text and as HTML formatted text because almost every receiver expects formatted messages these days. If you want/need to send plain text messages only, you can enable this in the advanced identity options. You might want to create a new identity for this if you want/need to select sending plain text messages on a case-by-case basis.


(90) Why are some texts linked while not being a link?

FairEmail will automatically link not linked web links (http and https) and not linked email addresses (mailto) for your convenience. However, texts and links are not easily distinguished, especially not with lots of top level domains being words. This is why texts with dots are sometimes incorrectly recognized as links, which is better than not recognizing some links.

Links for the tel, geo, rtsp and xmpp protocols will be recognized too, but links for less usual or less safe protocols like telnet and ftp will not be recognized. The regex to recognize links is already very complex and adding more protocols will make it only slower and possibly cause errors.

Note that original messages are shown exactly as they are, which means also that links are not automatically added.


(91) Can you add periodical synchronization to save battery power?

Synchronizing messages is an expensive proces because the local and remote messages need to be compared, so periodically synchronizing messages will not result in saving battery power, more likely the contrary.

See this FAQ about optimizing battery usage.


(92) Can you add spam filtering, verification of the DKIM signature and SPF authorization?

Spam filtering, verification of the DKIM signature and SPF authorization is a task of email servers, not of an email client. Servers generally have more memory and computing power, so they are much better suited to this task than battery-powered devices. Also, you'll want spam filtered for all your email clients, possibly including web email, not just one email client. Moreover, email servers have access to information, like the IP address, etc of the connecting server, which an email client has no access to.

Spam filtering based on message headers might have been feasible, but unfortunately this technique is patented by Microsoft.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see this FAQ for more information about this.

Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with filter rules too. Blocking the sender will create a filter rule to automatically move future messages of the same sender into the spam folder.

Note that the POP3 protocol gives access to the inbox only. So, it is won't be possible to report spam for POP3 accounts.

Note that you should not delete spam messages, also not from the spam folder, because the email server uses the messages in the spam folder to "learn" what spam messages are.

If you receive a lot of spam messages in your inbox, the best you can do is to contact the email provider to ask if spam filtering can be improved.

Also, FairEmail can show a small red warning flag when DKIM, SPF or DMARC authentication failed on the receiving server. You can enable/disable authentication verification in the display settings.

FairEmail can show a warning flag too if the domain name of the (reply) email address of the sender does not define an MX record pointing to an email server. This can be enabled in the receive settings. Be aware that this will slow down synchronization of messages significantly.

If legitimate messages are failing authentication, you should notify the sender because this will result in a high risk of messages ending up in the spam folder. Moreover, without proper authentication there is a risk the sender will be impersonated. The sender might use this tool to check authentication and other things.


(93) Can you allow installation/data storage on external storage media (sdcard)?

FairEmail uses services and alarms, provides widgets and listens for the boot completed event to be started on device start, so it is not possible to store the app on external storage media, like an sdcard. See also here.

Messages, attachments, etc stored on external storage media, like an sdcard, can be accessed by other apps and is therefore not safe. See here for the details.

When needed you can save (raw) messages via the three-dots menu just above the message text and save attachments by tapping on the floppy icon.

If you need to save on storage space, you can limit the number of days messages are being synchronized and kept for. You can change these settings by long pressing a folder in the folder list and selecting Edit properties.


(94) What does the red/orange stripe at the end of the header mean?

The red/orange stripe at the left side of the header means that the DKIM, SPF or DMARC authentication failed. See also this FAQ.


(95) Why are not all apps shown when selecting an attachment or image?

For privacy and security reasons FairEmail does not have permissions to directly access files, instead the Storage Access Framework, available and recommended since Android 4.4 KitKat (released in 2013), is used to select files.

If an app is listed depends on if the app implements a document provider. If the app is not listed, you might need to ask the developer of the app to add support for the Storage Access Framework.

Android Q will make it harder and maybe even impossible to directly access files, see here and here for more details.


(96) Where can I find the IMAP and SMTP settings?

The IMAP settings are part of the (custom) account settings and the SMTP settings are part of the identity settings.


(97) What is 'cleanup' ?

About each four hours FairEmail runs a cleanup job that:

  • Removes old message texts
  • Removes old attachment files
  • Removes old image files
  • Removes old local contacts
  • Removes old log entries

Note that the cleanup job will only run when the synchronize service is active.


(98) Why can I still pick contacts after revoking contacts permissions?

After revoking contacts permissions Android does not allow FairEmail access to your contacts anymore. However, picking contacts is delegated to and done by Android and not by FairEmail, so this will still be possible without contacts permissions.


(99) Can you add a rich text or markdown editor?

FairEmail provides common text formatting (bold, italic, underline, text size and color) via a toolbar that appears after selecting some text.

A Rich text or Markdown editor would not be used by many people on a small mobile device and, more important, Android doesn't support a rich text editor and most rich text editor open source projects are abandoned. See here for some more details about this.


(100) How can I synchronize Gmail categories?

You can synchronize Gmail categories by creating filters to label categorized messages:

  • Create a new filter via Gmail > Settings (wheel) > Filters and Blocked Addresses > Create a new filter
  • Enter a category search (see below) in the Has the words field and click Create filter
  • Check Apply the label and select a label and click Create filter

Possible categories:

category:social
category:updates
category:forums
category:promotions

Unfortunately, this is not possible for snoozed messages folder.

You can use Force sync in the three-dots menu of the unified inbox to let FairEmail synchronize the folder list again and you can long press the folders to enable synchronization.


(101) What does the blue/orange dot at the bottom of the conversations mean?

The dot shows the relative position of the conversation in the message list. The dot will be show orange when the conversation is the first or last in the message list, else it will be blue. The dot is meant as an aid when swiping left/right to go to the previous/next conversation.

The dot is disabled by default and can be enabled with the display settings Show relative conversation position with a dot.


(102) How can I enable auto rotation of images?

Images will automatically be rotated when automatic resizing of images is enabled in the settings (enabled by default). However, automatic rotating depends on the Exif information to be present and to be correct, which is not always the case. Particularly not when taking a photo with a camara app from FairEmail.

Note that only JPEG and PNG images can contain Exif information.


(104) What do I need to know about error reporting?

  • Error reports will help improve FairEmail
  • Error reporting is optional and opt-in
  • Error reporting can be enabled/disabled in the settings, section miscellaneous
  • Error reports will automatically be sent anonymously to Bugsnag
  • Bugsnag for Android is open source
  • See here about what data will be sent in case of errors
  • See here for the privacy policy of Bugsnag
  • Error reports will be sent to sessions.bugsnag.com:443 and notify.bugsnag.com:443

(105) How does the roam-like-at-home option work?

FairEmail will check if the country code of the SIM card and the country code of the network are in the EU roam-like-at-home countries and assumes no roaming if the country codes are equal and the advanced roam-like-at-home option is enabled.

So, you don't have to disable this option if you don't have an EU SIM or are not connected to an EU network.


(106) Which launchers can show a badge count with the number of unread messages?

Please see here for a list of launchers which can show the number of unread messages.

Note that the notification setting Show launcher icon with number of new messages needs to be enabled (default enabled).

Only new unread messages in folders set to show new message notifications will be counted, so messages marked unread again and messages in folders set to not show new message notification will not be counted.

Depending on what you want, the notification settings Let the number of new messages match the number of notifications needs to be enabled or disabled.

This feature depends on support of your launcher. FairEmail merely 'broadcasts' the number of unread messages using the ShortcutBadger library. If it doesn't work, this cannot be fixed by changes in FairEmail.

Some launchers display '1' for the monitoring notification, despite FairEmail explicitly requesting not to show a badge for this notification. This could be caused by a bug in the launcher app or in your Android version. Please double check if the notification dot is disabled for the receive (service) notification channel. You can go to the right notification channel settings via the notification settings of FairEmail. This might not be obvious, but you can tap on the channel name for more settings.

Note that Tesla Unread is not supported anymore.

FairEmail does send a new message count intent as well:

eu.faircode.email.NEW_MESSAGE_COUNT

The number of new, unread messages will be in an integer "count" parameter.


(107) How do I use colored stars?

You can set a colored star via the more message menu, via multiple selection (started by long pressing a message), by long pressing a star in a conversation or automatically by using rules.

You need to know that colored stars are not supported by the IMAP protocol and can therefore not be synchronized to an email server. This means that colored stars will not be visible in other email clients and will be lost on downloading messages again. However, the stars (without color) will be synchronized and will be visible in other email clients, when supported.

Some email clients use IMAP keywords for colors. However, not all servers support IMAP keywords and besides that there are no standard keywords for colors.


(108) Can you add permanently delete messages from any folder?

When you delete messages from a folder the messages will be moved to the trash folder, so you have a chance to restore the messages. You can permanently delete messages from the trash folder. Permanently delete messages from other folders would defeat the purpose of the trash folder, so this will not be added.


(109) Why is 'select account' available in official versions only?

Using select account to select and authorize Google accounts require special permission from Google for security and privacy reasons. This special permission can only be acquired for apps a developer manages and is responsible for. Third party builds, like the F-Droid builds, are managed by third parties and are the responsibility of these third parties. So, only these third parties can acquire the required permission from Google. Since these third parties do not actually support FairEmail, they are most likely not going to request the required permission.

You can solve this in two ways:

  • Switch to the official version of FairEmail, see here for the options
  • Use app specific passwords, see this FAQ

Using select account in third party builds is not possible in recent versions anymore. In older versions this was possible, but it will now result in the error UNREGISTERED_ON_API_CONSOLE.


(110) Why are (some) messages empty and/or attachments corrupt?

Empty messages and/or corrupt attachments are probably being caused by a bug in the server software. Older Microsoft Exchange software is known to cause this problem. Mostly you can workaround this by disabling Partial fetch in the advanced account settings:

Setup > Step 1 > Manage > Tap account > Tap advanced > Partial fetch > uncheck

After disabling this setting, you can use the message 'more' (three dots) menu to 'resync' empty messages. Alternatively, you can Delete local messages by long pressing the folder(s) in the folder list and synchronize all messages again.

Disabling Partial fetch will result in more memory usage.


(111) Is OAuth supported?

OAuth for Gmail is supported via the quick setup wizard. The Android account manager will be used to fetch and refresh OAuth tokens for selected on-device accounts. OAuth for non on-device accounts is not supported because Google requires a yearly security audit ($15,000 to $75,000) for this. You can read more about this here.

OAuth for Yandex and Yahoo is supported via the quick setup wizard.

OAuth for Office 365 accounts is supported, but Microsoft does not offer OAuth for Outlook, Live and Hotmail accounts (yet?).


(112) Which email provider do you recommend?

FairEmail is an email client only, so you need to bring your own email address.

There are plenty of email providers to choose from. Which email provider is best for you depends on your wishes/requirements. Please see the websites of Restore privacy or Privacy Tools for a list of privacy oriented email providers with advantages and disadvantages.

Some providers, like ProtonMail, Tutanota, use proprietary email protocols, which make it impossible to use third party email apps. Please see this FAQ for more information.

Using your own (custom) domain name, which is supported by most email providers, will make it easier to switch to another email provider.


(113) How does biometric authentication work?

If your device has a biometric sensor, for example a fingerprint sensor, you can enable/disable biometric authentication in the navigation (hamburger) menu of the setup screen. When enabled FairEmail will require biometric authentication after a period of inactivity or after the screen has been turned off while FairEmail was running. Activity is navigation within FairEmail, for example opening a conversation thread. The inactivity period duration can be configured in the miscellaneous settings. When biometric authentication is enabled new message notifications will not show any content and FairEmail won't be visible on the Android recents screen.

Biometric authentication is meant to prevent others from seeing your messages only. FairEmail relies on device encryption for data encryption, see also this FAQ.

Biometric authentication is a pro feature.


(114) Can you add an import for the settings of other email apps?

The format of the settings files of most other email apps is not documented, so this is difficult. Sometimes it is possible to reverse engineer the format, but as soon as the settings format changes things will break. Also, settings are often incompatible. For example, FairEmail has unlike most other email apps settings for the number of days to synchronize messages for and for the number of days to keep messages for, mainly to save on battery usage. Moreover, setting up an account/identity with the quick setup is simple, so it is not really worth the effort.


(115) Can you add email address chips?

Email address chips look nice, but cannot be edited, which is quite inconvenient when you made a typo in an email address.

Note that FairEmail will select the address only when long pressing an address, which makes it easy to delete an address.

Chips are not suitable for showing in a list and since the message header in a list should look similar to the message header of the message view it is not an option to use chips for viewing messages.

Reverted commit.


(116) How can I show images in messages from trusted senders by default?

You can show images in messages from trusted senders by default by enabled the display setting Automatically show images for known contacts.

Contacts in the Android contacts list are considered to be known and trusted, unless the contact is in the group / has the label 'Untrusted' (case insensitive).


(117) Can you help me restore my purchase?

Google manages all purchases, so as a developer I have little control over purchases. So, basically the only thing I can do, is give some advice:

  • Make sure you have an active, working internet connection
  • Make sure you are logged in with the right Google account and that there is nothing wrong with your Google account
  • Make sure you installed FairEmail via the right Google account if you configured multiple Google accounts on your device
  • Make sure the Play store app is up to date, please see here
  • Open the Play store app and wait at least a minute to give it time to synchronize with the Google servers
  • Open FairEmail and navigate to the pro features screen to let FairEmail check the purchases; sometimes it help to tap the buy button

You can also try to clear the cache of the Play store app via the Android apps settings. Restarting the device might be necessary to let the Play store recognize the purchase correctly.

Note that:

  • If you get ITEM_ALREADY_OWNED, the Play store app probably needs to be updated, please see here
  • Purchases are stored in the Google cloud and cannot get lost
  • There is no time limit on purchases, so they cannot expire
  • Google does not expose details (name, e-mail, etc) about buyers to developers
  • An app like FairEmail cannot select which Google account to use
  • It may take a while until the Play store app has synchronized a purchase to another device
  • Play Store purchases cannot be used without the Play Store, which is also not allowed by Play Store rules

If you cannot solve the problem with the purchase, you will have to contact Google about it.


(118) What does 'Remove tracking parameters' exactly?

Checking Remove tracking parameters will remove all UTM parameters from a link.


(119) Can you add colors to the unified inbox widget?

The widget is designed to look good on most home/launcher screens by making it monochrome and by using a half transparent background. This way the widget will nicely blend in, while still being properly readable.

Adding colors will cause problems with some backgrounds and will cause readability problems, which is why this won't be added.

Due to Android limitations it is not possible to dynamically set the opacity of the background and to have rounded corners at the same time.


(120) Why are new message notifications not removed on opening the app?

New message notifications will be removed on swiping notifications away or on marking the associated messages read. Opening the app will not remove new message notifications. This gives you a choice to leave new message notifications as a reminder that there are still unread messages.

On Android 7 Nougat and later new message notifications will be grouped. Tapping on the summary notification will open the unified inbox. The summary notification can be expanded to view individual new message notifications. Tapping on an individual new message notification will open the conversation the message it is part of. See this FAQ about when messages in a conversation will be auto expanded and marked read.


(121) How are messages grouped into a conversation?

By default FairEmail groups messages in conversations. This can be turned of in the display settings.

FairEmail groups messages based on the standard Message-ID, In-Reply-To and References headers. FairEmail does not group on other criteria, like the subject, because this could result in grouping unrelated messages and would be at the expense of increased battery usage.


(122) Why is the recipient name/email address show with a warning color?

The recipient name and/or email address in the addresses section will be shown in a warning color when the sender domain name and the domain name of the to address do not match. Mostly this indicates that the message was received via an account with another email address.


(123) What will happen when FairEmail cannot connect to an email server?

If FairEmail cannot connect to an email server to synchronize messages, for example if the internet connection is bad or a firewall or a VPN is blocking the connection, FairEmail will retry two times after waiting 4 and 8 seconds while keeping the device awake (=use battery power). If this fails, FairEmail will schedule an alarm to retry after 15, 30 and eventually every 60 minutes and let the device sleep (=no battery usage).

Note that Android doze mode does not allow to wake the device earlier than after 15 minutes.

Force sync in the three-dots menu of the unified inbox can be used to let FairEmail attempt to reconnect without waiting.

Sending messages will be retried on connectivity changes only (reconnecting to the same network or connecting to another network) to prevent the email server from blocking the connection permanently. You can pull down the outbox to retry manually.

Note that sending will not be retried in case of authentication problems and when the server rejected the message. In this case you can pull down the outbox to try again.


(124) Why do I get 'Message too large or too complex to display'?

The message Message too large or too complex to display will be shown if there are more than 100,000 characters or more than 500 links in a message. Reformatting and displaying such messages will take too long. You can try to use the original message view, powered by the browser, instead.


(125) What are the current experimental features?

Message classification (version 1.1438+)

Please see this FAQ for details.

Since this is an experimental feature, my advice is to start with just one folder.


(126) Can message previews be sent to my wearable?

FairEmail fetches a message in two steps:

  1. Fetch message headers
  2. Fetch message text and attachments

Directly after the first step new messages will be notified. However, only until after the second step the message text will be available. FairEmail updates exiting notifications with a preview of the message text, but unfortunately wearable notifications cannot be updated.

Since there is no guarantee that a message text will always be fetched directly after a message header, it is not possible to guarantee that a new message notification with a preview text will always be sent to a wearable.

If you think this is good enough, you can enable the notification option Only send notifications with a message preview to wearables and if this does not work, you can try to enable the notification option Show notifications with a preview text only. Note that this applies to wearables not showing a preview text too, even when the Android Wear app says the notification has been sent (bridged).

If you want to have the full message text sent to your wearable, you can enable the notification option Preview all text. Note that some wearables are known to crash with this option enabled.

If you use a Samsung wearable with the Galaxy Wearable (Samsung Gear) app, you might need to enable notifications for FairEmail when the setting Notifications, Apps installed in the future is turned off in this app.


(127) How can I fix 'Syntactically invalid HELO argument(s)'?

The error ... Syntactically invalid HELO argument(s) ... means that the SMTP server rejected the local IP address or host name. You can likely fix this error by enabling or disabling the advanced indentity option Use local IP address instead of host name.


(128) How can I reset asked questions, for example to show images?

You can reset asked questions via the three dots overflow menu in the miscellaneous settings.


(129) Are ProtonMail, Tutanota supported?

ProtonMail uses a proprietary email protocol and does not directly support IMAP, so you cannot use FairEmail to access ProtonMail.

Tutanota uses a proprietary email protocol and does not support IMAP, so you cannot use FairEmail to access Tutanota.


(130) What does message error ... mean?

A series of lines with orangish or red texts with technical information means that debug mode was enabled in the miscellaneous settings.

The warning No server found at ... means that there was no email server registered at the indicated domain name. Replying to the message might not be possible and might result in an error. This could indicate a falsified email address and/or spam.

The error ... ParseException ... means that there is a problem with a received message, likely caused by a bug in the sending software. FairEmail will workaround this is in most cases, so this message can mostly be considered as a warning instead of an error.

The error ...SendFailedException... means that there was a problem while sending a message. The error will almost always include a reason. Common reasons are that the message was too big or that one or more recipient addresses were invalid.

The warning Message too large to fit into the available memory means that the message was larger than 10 MiB. Even if your device has plenty of storage space Android provides limited working memory to apps, which limits the size of messages that can be handled.

Please see here for other error messages in the outbox.


(131) Can you change the direction for swiping to previous/next message?

If you read from left to right, swiping to the left will show the next message. Similarly, if you read from right to left, swiping to the right will show the next message.

This behavior seems quite natural to me, also because it is similar to turning pages.

Anyway, there is a behavior setting to reverse the swipe direction.


(132) Why are new message notifications silent?

Notifications are silent by default on some MIUI versions. Please see here how you can fix this.

There is a bug in some Android versions causing setOnlyAlertOnce to mute notifications. Since FairEmail shows new message notifications right after fetching the message headers and FairEmail needs to update new message notifications after fetching the message text later, this cannot be fixed or worked around by FairEmail.

Android might rate limit the notification sound, which can cause some new message notifications to be silent.


(133) Why is ActiveSync not supported?

The Microsoft Exchange ActiveSync protocol is patented and can therefore not be supported. For this reason you won't find many, if any, other email clients supporting ActiveSync.

The Microsoft Exchange Web Services protocol is being phased out.

Note that the desciption of FairEmail starts with the remark that non-standard protocols, like Microsoft Exchange Web Services and Microsoft ActiveSync are not supported.


(134) Can you add deleting local messages?

POP3

In the account settings (Setup, step 1, Manage, tap account) you can enable Leave deleted messages on server.

IMAP

Since the IMAP protocol is meant to synchronize two ways, deleting a message from the device would result in fetching the message again when synchronizing again.

However, FairEmail supports hiding messages, either via the three-dots menu in the action bar just above the message text or by multiple selecting messages in the message list. Basically this is the same as "leave on server" of the POP3 protocol with the advantage that you can show the messages again when needed.

Note that it is possible to set the swipe left or right action to hide a message.


(135) Why are trashed messages and drafts shown in conversations?

Individual messages will rarely be trashed and mostly this happens by accident. Showing trashed messages in conversations makes it easier to find them back.

You can permanently delete a message using the message three-dots delete menu, which will remove the message from the conversation. Note that this irreversible.

Similarly, drafts are shown in conversations to find them back in the context where they belong. It is easy to read through the received messages before continuing to write the draft later.


(136) How can I delete an account/identity/folder?

Deleting an account/identity/folder is a little bit hidden to prevent accidents.

  • Account: Setup > Step 1 > Manage > Tap account
  • Identity: Setup > Step 2 > Manage > Tap identity
  • Folder: Long press the folder in the folder list > Edit properties

In the three-dots overflow menu at the top right there is an item to delete the account/identity/folder.


(137) How can I reset 'Don't ask again'?

You can reset all questions set to be not asked again in the miscellaneous settings.


(138) Can you add calendar/contact management/synchronizing?

Calendar and contact management can better be done by a separate, specialized app. Note that FairEmail is a specialized email app, not an office suite.

Also, I prefer to do a few things very well, instead of many things only half. Moreover, from a security perspective, it is not a good idea to grant many permissions to a single app.

You are advised to use the excellent, open source DAVx⁵ app to synchronize/manage your calendars/contacts.

Most providers support exporting your contacts. Please see here about how you can import contacts if synchronizing is not possible.

Note that FairEmail does support replying to calendar invites (a pro feature) and adding calendar invites to your personal calendar.


(139) How do I fix 'User is authenticated but not connected'?

In fact this Microsoft Exchange specific error is an incorrect error message caused by a bug in older Exchange server software.

The error User is authenticated but not connected might occur if:

  • Push messages are enabled for too many folders: see this FAQ for more information and a workaround
  • The account password was changed: changing it in FairEmail too should fix the problem
  • An alias email address is being used as username instead of the primary email address
  • An incorrect login scheme is being used for a shared mailbox: the right scheme is username@domain\SharedMailboxAlias

The shared mailbox alias will mostly be the email address of the shared account, like this:

dig@eksempel.dk\delt@eksempel.dk

Note that it should be a backslash and not a forward slash.


(140) Why does the message text contain strange characters?

Displaying strange characters is almost always caused by specifying no or an invalid character encoding by the sending software. FairEmail will assume ISO 8859-1 when no character set or when US-ASCII was specified. Other than that there is no way to reliably determine the correct character encoding automatically, so this cannot be fixed by FairEmail. The right action is to complain to the sender.


(141) How can I fix 'A drafts folder is required to send messages'?

To store draft messages a drafts folder is required. In most cases FairEmail will automatically select the drafts folders on adding an account based on the attributes the email server sends. However, some email servers are not configured properly and do not send these attributes. In this case FairEmail tries to identify the drafts folder by name, but this might fail if the drafts folder has an unusual name or is not present at all.

You can fix this problem by manually selecting the drafts folder in the account settings (Setup, step 1, tap account, at the bottom). If there is no drafts folder at all, you can create a drafts folder by tapping on the '+' button in the folder list of the account (tap on the account name in the navigation menu).

Some providers, like Gmail, allow enabling/disabling IMAP for individual folders. So, if a folder is not visible, you might need to enable IMAP for the folder.

Quick link for Gmail: https://mail.google.com/mail/u/0/#settings/labels


(142) How can I store sent messages in the inbox?

Generally, it is not a good idea to store sent messages in the inbox because this is hard to undo and could be incompatible with other email clients.

That said, FairEmail is able to properly handle sent messages in the inbox. FairEmail will mark outgoing messages with a sent messages icon for example.

The best solution would be to enable showing the sent folder in the unified inbox by long pressing the sent folder in the folder list and enabling Show in unified inbox. This way all messages can stay where they belong, while allowing to see both incoming and outgoing messages at one place.

If this is not an option, you can create a rule to automatically move sent messages to the inbox or set a default CC/BCC address in the advanced identity settings to send yourself a copy.


(143) Can you add a trash folder for POP3 accounts?

POP3 is a very limited protocol. Basically only messages can be downloaded and deleted from the inbox. It is not even possible to mark a message read.

Since POP3 does not allow access to the trash folder at all, there is no way to restore trashed messages.

Note that you can hide messages and search for hidden messages, which is similar to a local trash folder, without suggesting that trashed messages can be restored, while this is actually not possible.

Version 1.1082 added a local trash folder. Note that trashing a message will permanently remove it from the server and that trashed messages cannot be restored to the server anymore.


(144) How can I record voice notes?

To record voice notes you can press this icon in the bottom action bar of the message composer:

External image

This requires a compatible audio recorder app to be installed. In particular this common intent needs to be supported.

For example this audio recorder is compatible.

Voice notes will automatically be attached.


(145) How can I set a notification sound for an account, folder or sender?

Account:

  • Enable Separate notifications in the advanced account settings (Setup, step 1, Manage, tap account, tap Advanced)
  • Long press the account in the account list (Setup, step 1, Manage) and select Edit notification channel to change the notification sound

Folder:

  • Long press the folder in the folder list and select Create notification channel
  • Long press the folder in the folder list and select Edit notification channel to change the notification sound

Sender:

  • Open a message from the sender and expand it
  • Expand the addresses section by tapping on the down arrow
  • Tap on the bell icon to create or edit a notification channel and to change the notification sound

The order of precendence is: sender sound, folder sound, account sound and default sound.

Setting a notification sound for an account, folder or sender requires Android 8 Oreo or later and is a pro feature.


(146) How can I fix incorrect message times?

Since the sent date/time is optional and can be manipulated by the sender, FairEmail uses the server received date/time by default.

Sometimes the server received date/time is incorrect, mostly because messages were incorrectly imported from another server and sometimes due to a bug in the email server.

In these rare cases, it is possible to let FairEmail use either the date/time from the Date header (sent time) or from the Received header as a workaround. This can be changed in the advanced account settings: Setup, step 1, Manage, tap account, tap Advanced.

This will not change the time of already synchronized messages. To solve this, long press the folder(s) in the folder list and select Delete local messages and Synchronize now.


(147) What should I know about third party versions?

You likely came here because you are using a third party build of FairEmail.

There is only support on the latest Play store version, the latest GitHub release and the F-Droid build, but only if the version number of the F-Droid build is the same as the version number of the latest GitHub release.

F-Droid builds irregularly, which can be problematic when there is an important update. Therefore you are advised to switch to the GitHub release.

The F-Droid version is built from the same source code, but signed differently. This means that all features are available in the F-Droid version too, except for using the Gmail quick setup wizard because Google approved (and allows) one app signature only. For all other email providers, OAuth access is only available in Play Store versions and Github releases, as the email providers only permit the use of OAuth for official builds.

Note that you'll need to uninstall the F-Droid build first before you can install a GitHub release because Android refuses to install the same app with a different signature for security reasons.

Note that the GitHub version will automatically check for updates. When desired, this can be turned off in the miscellaneous settings.

Please see here for all download options.

If you have a problem with the F-Droid build, please check if there is a newer GitHub version first.


(148) How can I use an Apple iCloud account?

There is a built-in profile for Apple iCloud, but if needed you can find the right settings here.

When using two-factor authentication you might need to use an app-specific password.


(149) How does the unread message count widget work?

The unread message count widget shows the number of unread messages either for all accounts or for a selected account, but only for the folders for which new message notifications are enabled.

Tapping on the notification will synchronize all folders for which synchronization is enabled and will open:

  • the start screen when all accounts were selected
  • a folder list when a specific account was selected and when new message notifications are enabled for multiple folders
  • a list of messages when a specific account was selected and when new message notifications are enabled for one folder

(150) Can you add cancelling calendar invites?

Cancelling calendar invites (removing calendar events) requires write calendar permission, which will result in effectively granting permission to read and write all calendar events of all calendars.

Given the goal of FairEmail, privacy and security, and given that it is easy to remove a calendar event manually, it is not a good idea to request this permission for just this reason.

Inserting new calendar events can be done without permissions with special intents. Unfortunately, there exists no intent to delete existing calendar events.


(151) Can you add backup/restore of messages?

An email client is meant to read and write messages, not to backup and restore messages. Note that breaking or losing your device, means losing your messages!

Instead, the email provider/server is responsible for backups.

If you want to make a backup yourself, you could use a tool like imapsync.

If you want to import an mbox file to an existing email account, you can use Thunderbird on a desktop computer and the ImportExportTools add-on.


(152) How can I insert a contact group?

You can insert the email addresses of all contacts in a contact group via the three dots menu of the message composer.

You can define contact groups with the Android contacts app, please see here for instructions.


(153) Why does permanently deleting Gmail message not work?

You might need to change the Gmail IMAP settings on a desktop browser to make it work:

  • When I mark a message in IMAP as deleted: Auto-Expunge off - Wait for the client to update the server.
  • When a message is marked as deleted and expunged from the last visible IMAP folder: Immediately delete the message forever

Note that archived messages can be deleted only by moving them to the trash folder first.

Some background: Gmail seems to have an additional message view for IMAP, which can be different from the main message view.


(154) Can you add favicons as contact photos?

Besides that a favicon might be shared by many email addresses with the same domain name and therefore is not directly related to an email address, favicons can be used to track you.


(155) What is a winmail.dat file?

A winmail.dat file is sent by an incorrectly configured Outlook client. It is a Microsoft specific file format (TNEF) containing a message and possibly attachments.

You can find some more information about this file here.

You can view it with for example the Android app Letter Opener.


(156) How can I set up an Office 365 account?

An Office 365 account can be set up via the quick setup wizard and selecting Office 365 (OAuth).

If the wizard ends with AUTHENTICATE failed, IMAP and/or SMTP might be disabled for the account. In this case you should ask the administrator to enable IMAP and SMTP. The procedure is documented here.

If you've enabled security defaults in your organization, you might need to enable the SMTP AUTH protocol. Please see here about how to.


(157) How can I set up an Free.fr account?

Veuillez voir ici pour les instructions.

SMTP est désactivé par défaut, veuillez voir ici comment il peut être activé.

Veuillez voir ici pour un guide détaillé.


(158) Which camera / audio recorder do you recommend?

To take photos and to record audio a camera and an audio recorder app are needed. The following apps are open source cameras and audio recorders:

To record voice notes, etc, the audio recorder needs to support MediaStore.Audio.Media.RECORD_SOUND_ACTION. Oddly, most audio recorders seem not to support this standard Android action.


(159) What are Disconnect's tracker protection lists?

Please see here for more information about Disconnect's tracker protection lists.

After downloading the lists in the privacy settings, the lists can optionally be used:

  • to warn about tracking links on opening links
  • to recognize tracking images in messages

Tracking images will be disabled only if the corresponding main 'disable' option is enabled.

Tracking images will not be recognized when the domain is classified as 'Content', see here for more information.

This command can be sent to FairEmail from an automation app to update the protection lists:

(adb shell) am startservice -a eu.faircode.email.DISCONNECT.ME

Updating once a week will probably be sufficient, please see here for recent lists changes.


(160) Can you add permanent deletion of messages without confirmation?

Permanent deletion means that messages will irreversibly be lost, and to prevent this from happening accidentally, this always needs to be confirmed. Even with a confirmation, some very angry people who lost some of their messages through their own fault contacted me, which was a rather unpleasant experience :-(

Advanced: the IMAP delete flag in combination with the EXPUNGE command is not supportable because both email servers and not all people can handle this, risking unexpected loss of messages. A complicating factor is that not all email servers support UID EXPUNGE.


(161) Can you add a setting to change the primary and accent color?*

If I could, I would add a setting to select the primary and accent color right away, but unfortunately Android themes are fixed, see for example here, so this is not possible.


(162) Is IMAP NOTIFY supported?*

Yes, IMAP NOTIFY has been supported since version 1.1413.

IMAP NOTIFY support means that notifications for added, changed or deleted messages of all subscribed folders will be requested and if a notification is received for a subscribed folder, that the folder will be synchronized. Synchronization for subscribed folders can therefore be disable, saving folder connections to the email server.

Important: push messages (=always sync) for the inbox and subscription management (receive settings) need to be enabled.

Important: most email servers do not support this! You can check the log via the navigation menu if an email server supports the NOTIFY capability.


(163) What is message classification?

This is an experimental feature!

Message classification will attempt to automatically group emails into classes, based on their contents, using Bayesian statistics. In the context of FairEmail, a folder is a class. So, for example, the inbox, the spam folder, a 'marketing' folder, etc, etc.

You can enable message classification in the miscellaneous settings. This will enable 'learning' mode only. The classifier will 'learn' from new messages in the inbox and spam folder by default. The folder property Classify new messages in this folder will enable or disable 'learning' mode for a folder. You can clear local messages (long press a folder in the folder list of an account) and synchronize the messages again to classify existing messages.

Each folder has an option Automatically move classified messages to this folder ('auto classification' for short). When this is turned on, new messages in other folders which the classifier thinks belong to that folder will be automatically moved.

The option Use local spam filter in the report spam dialog will turn on message classification in the miscellaneous settings and auto classification for the spam folder. Please understand that this is not a replacement for the spam filter of the email server and can result in false positives and false negatives. See also this FAQ.

A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the 'marketing' folder, FairEmail will start moving similar messages automatically into this folder. Or, the other way around, after moving some messages out of the 'marketing' folder, FairEmail will stop moving similar messages automatically into this folder. This will work best with messages with similar content (email addresses, subject and message text).

Classification should be considered as a best guess - it might be a wrong guess, or the classifier might not be confident enough to make any guess. If the classifier is unsure, it will simply leave an email where it is.

To prevent the email server from moving a message into the spam folder again and again, auto classification out of the spam folder will not be done.

The message classifier calculates the probability a message belongs in a folder (class). There are two options in the miscellaneous settings which control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:

  • Minimum class probability: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
  • Minimum class difference: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)

Both conditions must be satisfied before a message will be moved.

Considering the defaults option values:

  • Æbler 40% og bananer 30% vil blive tilsidesat, da forskellen på 25% ligger under et minimum på 50%
  • Æbler 15% og bananer 5% vil blive tilsidesat, da sandsynligheden for æbker er under et minimum på 20%
  • Æbler 50% og bananer 20% vil resultere i valg af æbler

Classification is optimized to use as little resources as possible, but will inevitably use some extra battery power.

You can delete all classification data by turning classification in the miscellaneous settings three times off.

Filter rules will be executed before classification.

Message classification is a pro feature, except for the spam folder.
