```
Dette betyder, at den redigerede afsenderadresse automatisk erstattes af en bekræftet adresse inden bekedafsendelsen.
Bemærk, at dette er uafhængigt af beskedmodtagelse.
**(34) Hvordan matches identiteter?**
Identiteter matches efter konto. For indgående beskeder tjekkes adresserne *til*, *cc*, *bcc*, *fra* og *(X-)leverede/konvolut/originale-til* (i nævnte rækkefølge), og for udgående beskeder (kladder, udbakke og sendt) tjekkes kun *fra*-adresserne. Matchende adresser har forrang frem for delvist matchende adresser, undtagen *leveret til*-adresser.
Den matchede adresse vises som *via* i adresseafsnittet på modtagne beskeder (mellem besked-header og beskedtekst).
Bemærk, at identiteter skal være aktiverede for at kunne matches, samt at identiteter for andre konti ikke overvejes.
Match udføres kun én gang efter modtagelse af en besked, så evt. opsætningsændringer ændrer ikke eksisterende beskeder. Du kan dog rydde lokale beskeder vha. langt tryk på en mappe i mappelisten og så synkronisere beskederne igen.
Det er muligt at opsætte en [regex](https://en.wikipedia.org/wiki/Regular_expression) i identitetsindstillingerne for at få en e-mailadresses matchende **brugernavn** (delen før @-tegnet).
Bemærk, at domænenavnet (alt efter @) altid skal være identisk med identitetens domænenavn.
Vil du gerne matche en fang-alle e-mailadresse, er denne regex for det meste OK:
```
.*
```
Vil du matche e-mailadresserne til specielle formål, abc@eksemepel.dk og xyx@eksemepel.dk og også gerne have en fallback e-mailadresse, hoved@eksemepel.dk, kan du gøre noget ala dette:
* 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 samt åbne links?**
Visning af fjernlagrede billeder (tjek også [denne FAQ](#user-content-faq27)) samt åbning af links fortæller muligvis ikke kun afsenderen, at du har set beskeden, men lækker også din IP-adresse. Se også dette spørgsmål: [Hvorfor et e-mail link er farligere end et websøgningslink?](https://security.stackexchange.com/questions/241139/why-emails-link-is-more-dangerous-than-web-searchs-link).
Åbning af vedhæftninger eller visning af en original besked kan muligvis indlæse eksternt indhold og eksekvere scripts, hvilket ikke alene kan forårsage læk af fortrolige oplysninger, men tillige udgøre en sikkerhedsrisiko.
Bemærk, at dine kontakter, uden deres vidende, kan sende ondsindede beskeder, hvis de er blevet inficeret med malware.
FairEmail genformaterer beskeder, hvilket får dem til at se anderledes ud end originalen, men tillige 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](https://blog.filippo.io/how-the-new-gmail-image-proxy-works-and-what-this-means-for-you/), er dette endnu mindre sikkert, da Google også er involveret.
Du kan som standard få vist billeder og originale beskeder for betroede afsendere fra gang til gang ved at markere *Spørg ikke igen om...*.
Vil du nulstille *Åbn med* standard-apps, så tjek [hér](https://www.androidauthority.com/how-to-set-default-apps-android-clear-621269/).
**(36) Hvordan krypteres indstillingsfiler?**
Kort version: AES 256 bit
Lang version:
* 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 adgangskoderr?**
Alle understøttede Android-versioner [krypterer alle brugerdata](https://source.android.com/security/encryption), så alle data, inkl. brugernavne, adgangskoder, beskeder mv., lagres krypteret.
Er enheden sikret med en PIN-kode, mønster eller adgangskode, kan konto- og identitetsadgangskoder gøres synlige. Er dette er et problem, fordi enheden deles med andre, så overvej at anvende [brugerprofiler](https://www.howtogeek.com/333484/how-to-set-up-multiple-user-profiles-on-android/).
**(39) Hvordan kan FairEmails batteriforbrug reduceres?**
Som standard rapporterer 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 *Mobilnetværksstandby*. Er dette ikke tilfældet, så aktivé *Automatisk optimering* i modtagelsesindstillingerne. Hjælper dette ikke, så [bed om support](https://contact.faircode.eu/?product=fairemailsupport).
Det er uundgåeligt, at beskedsynkronisering forbruger strøm, da det kræver adgang til både netværket og beskeddatabasen.
Sammenlignes batteriforbruget for FairEmail med en anden e-mailklient, skal den anden e-mailklient være opsat på lignende vis. Det er f.eks. ikke retvisende at sammenligne kontinuerlig synk (push-beskeder) og periodisk (ikke-regelmæssig) tjek for nye beskeder.
Gentilslutninger til en e-mailserver forbruger ekstra strøm, hvilket f.eks. en ustabil Internetforbindelse vil resultere i. Visse e-mailservere afslutter også ikke-aktive forbindelser for tidligt, selvom [standarden](https://tools.ietf.org/html/rfc2177) dikterer, at en ikke-aktiv forbindelse bør holdes åben i 29 minutter. I sådanne tilfælde vil du måske kun synkronisere periodisk, f.eks. hver time, i stedet for kontinuerligt. Bemærk, at hyppig polling (mere end hvert ca. 30.-60. min) antageligt vil forbruge mere strøm end kontinuerlig synkronisering, da serverforbindelsesoprettelsen samt lokal-/fjernbeskedsmatchning kræver ressourcer.
[På visse enheder](https://dontkillmyapp.com/) er det nødvendigt at *deaktivere* batterioptimering (opsætningstrin 4) for at holde forbindelser til e-mailservere åbne. Faktisk kan aktiv batterioptimering resultere i ekstra strømforbrug på alle enheder, selvom det lyder selvmodsigende!
Størstedelen af strømforbruget, fraset at kigge beskeder, skyldes synkronisering (modtagelse/afsendelse) af beskeder. For at reducere strømforbruget så indstil antallet af synkroniseringsdage til en lavere værdi, især hvis der er en masse nylige beskeder i en mappe. Langt tryk på et mappenavn i mappelisten, og valg af *Redigér egenskaber* giver adgang til denne indstilling.
Har du mindst én gang om dagen Internetforbindelse, er det tilstrækkeligt at synkronisere beskeder blot for én dag.
Bemærk, det antal dage, hvori beskeder *beholdes* kan indstilles til en større værdi end til det antal dage, hvori beskeder *synkroniseres*. Du kan f.eks. indledningsvis synkronisere beskeder i et større antal dage, og efter at dette er afsluttet reducer antallet af beskedsynkroniseringsdage, men bevare antallet af dage, hvori beskeder skal beholdes. Efter reducering af det antal dage, hvori beskeder beholdes, ønsker du måske at køre oprydning i diverse indstillinger for at fjerne gamle filer.
I modtagelsesindstillingerne kan du aktivere altid at synkronisere stjernemarkerede beskeder, hvilket lader dig beholde ældre beskeder, selvom du synkroniserer beskeder i et begrænset antal dage.
Deaktivering af mappeindstillingen *Download automatisk beskedtekster og vedhæftninger* vil betyde mindre netværkstrafik og dermed lavere strømforbrug. Du kan deaktivere denne indstilling for eksempelvis Sendt-mappen og arkivet.
Synkronisering af beskeder om natten er for det meste unødvendigt, så du kan spare strøm ved ikke at gøre dette. Der kan i indstillingerne vælges en tidsplan for beskedsynkronisering (dette er en Pro-funktion).
FairEmail vil som standard synkronisere mappelisten ved hver tilslutning. Da mapper typisk ikke oprettes/omdøbes/slettes særligt hyppigt, kan der spares netværks- og strømforbrug ved at deaktivere dette i modtagelsesindstillingerne.
Som standard vil FairEmail ved hver tilslutning tjekke, om gamle beskeder er blevet slettet fra serveren. Har du ikke noget imod, at gamle beskederr, som er blevet slettet fra serveren stadig er synlige i FairEmail, kan du spare netværks- og strømforbrug ved at deaktivere dette i modtagelsesindstillingerne.
Visse udbydere følger ikke IMAP-standarden og holder ikke forbindelserne åbne længe nok. Dette tvinger FairEmail til ofte at oprette forbindelse igen, hvilket medfører ekstra strømforbrug. Du kan tjekke *Loggen* via hovednavigeringsmenuen for at se, om der er hyppige forbindelsesgenoprettelser (forbindelse lukket/nulstillet, læse-/skrivefejl/timeout mv.). Du kan omgå dette ved i de avancerede kontoindstillinger at sænke keep-alive intervallet til f.eks. 9 eller 15 min. Bemærk, at batterioptimering skal deaktiveres i opsætningstrin 4 for pålideligt at holde forbindelserne i live.
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. Du kan tjekke *Loggen* via hovednavigeringsmenuen for at se, hvorvidt din udbyder gør dette. Benytter din udbyder [Dovecot](https://www.dovecot.org/) som IMAP-server, kan du bede udbyderen ændre indstillingen [imap_idle_notify_interval](https://wiki.dovecot.org/Timeouts) til en højere værdi eller, endnu bedre, deaktivere dette. Er din udbyder ikke er i stand eller villig til at ændre/deaktivere dette, så overvej at skifte til periodisk i stedet for kontinuerlig synkronisering. Du kan ændre dette i modtagelsesindstillingerne.
Ses meddelelsen *Denne udbyder understøtter ikke push-beskeder* under opsætningen af en konto, så overvej mhp. at reducere strømforbruget at skifte til en moderne udbyder, der understøtter push-beskeder (IMAP IDLE).
Har din enhed en [AMOLED](https://en.wikipedia.org/wiki/AMOLED)-skærm, kan du ved at skifte til det sorte tema spare strøm, mens du ser beskeder.
Er autooptimering i modtagelsesindstillingerne aktiveret, omskiftes en konto til periodisk at tjekke for nye beskeder, når e-mailserveren:
* Says '*Still here*' within 3 minutes
* E-mailserveren understøtter ikke push-beskeder
* Keep-alive intervallet er kortere end 12 minutes
Desuden vil Papirkurv- og Spam-mapperne automatisk blive indstillet til at tjekke for nye beskeder efter tre successive [for mange samtidige forbindelser](#user-content-faq23)-fejl.
**(40) Hvordan kan FairEmails dataforbrug reduceres?**
Man kan grundlæggende reducere netværksforbruget på samme måde som strømforbruget. Tjek forslagene i foregående spørgsmål.
Det er uundgåeligt, at data vil blive forbrugt ved meddelelsessynkronisering.
Mistes forbindelsen til e-mail-serveren, vil FairEmail altid gensynkronisere meddelelserne for at sikre, at de alle er tilgængelige. Er forbindelsen ustabil, kan dette resultere i ekstra dataforbrug. I så tilfælde er det en god idé at reducere antallet af beskedsynkroniseringsdage til et minimum (tjek foregående spørgsmål) eller at skifte til periodisk beskedsynkronisering (modtagelsesindstillinger).
For at reducere dataforbruget, kan disse avancerede modtagelsesindstillinger ændres:
* Tjek, om gamle beskeder er fjernet fra serveren
* Synkronisér (delte) mappelister: Deaktivér
Som standard henter FairEmail ikke beskedtekster og vedhæftninger større end 256 KiB på takserede Internetforbindelser (mobildata eller betalt Wi-Fi). Dette kan ændres i forbindelsesindstillingerne.
**(41) Hvordan rettes fejlen 'Handshake mislykkedes'?**
Der er flere mulige årsager, så tjek slutningen af dette svar.
Fejlen '*Handshake mislykkedes ... WRONG_VERSION_NUMBER ...*' kan betyde, at du forsøger at oprette forbindelse til en IMAP- eller SMTP-server uden en krypteret forbindelse, typisk via port 143 (IMAP) og port 25 (SMTP), eller at der anvendes en forkert protokol (SSL/TLS eller STARTTLS).
De fleste udbydere leverer krypterede forbindelser vha. forskellige porte, typisk port 993 (IMAP) og port 465/587 (SMTP).
Understøtter din udbyder ikke krypterede forbindelser, bør du anmode om, at dette muliggøres. Er dette ikke en mulighed, kan du aktivere *Tillad usikre forbindelser* i både de avancerede indstillinger OG konto-/identitetsindstillingerne.
Tjek også [denne FAQ](#user-content-faq4).
Fejlen '*Handshake mislykkedes ... SSLV3_ALERT_ILLEGAL_PARAMETER ...*' er enten forårsaget af en fejl i implementeringen af SSL-protokollen eller ved en for kort DH-nøgle på e-mailserveren og kan desværre ikke rettes af FairEmail.
Fejlen '*Handshake mislykkedes ... HANDSHAKE_FAILURE_ON_CLIENT_HELLO ...*' kan være forårsaget af, at udbyderen stadig anvender RC4, hvilket siden [Android 7](https://developer.android.com/about/versions/nougat/android-7.0-changes.html#tls-ssl) ikke længere understøttes.
Fejlen '*Handshake mislykkedes ... UNSUPPORTED_PROTOCOL eller TLSV1_ALERT_PROTOCOL_VERSION ...*' kan forårsages af aktivering af forbindelseshærdning i forbindelsesindstillingerne eller af, at Android ikke længere understøtter ældre protokoller såsom SSLv3.
Android 8 Oreo og senere [understøtter ikke længere](https://developer.android.com/about/versions/oreo/android-8.0-changes#security-all) SSLv3. Der er ingen måde at løse manglende RC4- og SSLv3-understøttelse på, da disse er helt fjernet fra Android.
Du kan benytte [dette websted](https://ssl-tools.net/mailservers) eller [dette websted](https://www.immuniweb.com/ssl/) til at tjekke for SSL-/TLS-problemer på e-mailservere.
**(42) Kan der blive tilføjet en ny udbyder på udbyderlisten?**
Anvendes udbyderen af flere end blot et par personer, ja gerne.
Flg. oplysninger vil være påkrævet:
```
// dette kræves ikke
```
EFF-[skrivere](https://www.eff.org/nl/deeplinks/2018/06/announcing-starttls-everywhere-securing-hop-hop-email-delivery): "*Der er dog stadig ingen garanti for, at din kommunikation bliver krypteret, selvom du opsætter STARTTLS korrekt samt anvender et gyldigt certifikat.*"
Så rene SSL-forbindelser er sikrere end at anvende [STARTTLS](https://en.wikipedia.org/wiki/Opportunistic_TLS) og derfor foretrukne.
Sørg for at tjekke, at beskedmodtagelse/-afsendelse fungerer korrekt, før du kontakter mig vedr. udbydertilføjelse.
Tjek nedenfor, hvordan du kontakter mig.
**(43) Kan man vise den originale ... ?**
Vis original, viser den originale besked, således som afsenderen har sendt den, inkl. originale skrifttyper, farver, margner mv. FairEmail ændrer på ingen måde på dette, bortset fra at anmode om [TEXT_AUTOSIZING](https://developer.android.com/reference/android/webkit/WebSettings.LayoutAlgorithm), som *forsøger* at gøre en lille tekst mere læsbar.
**~~(44) Kan man få vist kontaktfotos/-identikoner i Sendt-mappen?~~**
~~Kontaktfotos og identikoner vises altid for afsenderen, da dette er nødvendigt for konversationstråde.~~ ~~At få kontaktfotos til både afsender og modtager er ikke rigtig en mulighed, da hentning af et kontaktfoto er ressourcekrævende.~~
**(45) Hvordan retter man problemet 'Denne nøgle er utilgængelig. For at bruge den, skal du importere den som en af dine egne!' ?**
Du får beskeden *Denne nøgle er ikke tilgængelig. For at bruge den, skal du importere den som en af dine egne!*, når du forsøger at dekryptere en besked med en offentlig nøgle. For at løse dette, skal den private nøgle importeres.
**(46) Hvorfor genindlæses beskedlisten hele tiden?**
Ses en 'spinner' øverst på beskedlisten, synkroniseres mappen stadig med fjernserveren. Status for synkroniseringen kan ses i mappelisten. Tjek forklaringen på, hvad ikoner og tal betyder.
Hastigheden på enhed og Internetforbindelse samt antal beskedsynkroniseringsdage bestemmer, hvor længe synkronisering vil tage. Bemærk, at antal beskedsynkroniseringsdage i de fleste tilfælde ikke bør opsættes til mere end én dag. Tjek også [denne FAQ](#user-content-faq39).
**(47) Hvordan løses fejlen 'Ingen primær konto eller udkastmappe'?**
Fejlmeddelelsen *Ingen primær konto eller udkastmappe* vises, når en besked forsøges oprettet, uden at nogen primær konto er angivet eller en udkastmappe er valgt for den primære konto. Dette kan f.eks. ske, når FairEmail startes fra en anden app for at skrive en besked. FairEmail skal vide, hvor udkast skal gemmes, så det er nødvendigt at vælge en konto til at udgøre den primære konto samt/eller vælge en udkastmappe for denne.
Dette kan også ske, når man forsøger at svare på en besked, eller videresende en besked fra en konto uden udkastmappe, mens der ikke er nogen primær konto, eller når den primære konto ikke har en udkastmappe.
Tjek [denne FAQ](#user-content-faq141) for yderligere information.
**~~(48) Hvordan løses fejlen 'Ingen primær konto/arkivmappe'?~~**
~~Fejlmeddelelsen *Ingen primær konto eller ingen arkivmappe* ses, når der søges efter beskeder fra en anden app. FairEmail skal vide, hvor der skal søges, så det er nødvendigt at vælge en konto til at udgøre den primære konto samt/eller vælge en arkivmappe for denne.~~
**(49) Hvordan løses fejlen 'En forældet app har sendt en filsti i stedet for en fil-stream'?**
Der er sandsynligvis valgt eller afsendt en vedhæftning/billede med en forældet filhåndtering eller en forældet app, der antager, at alle apps stadig har lagerpladstilladelser. Af sikkerheds- og fortrolighedsårsager har moderne apps såsom FairEmail ikke længere fuld adgang til alle filer. Dette kan resultere i fejlmeddelelsen *En forældet app sendte en filsti i stedet for en filstream*, hvis et filnavn i stedet for en filstrøm deles med FairEmail, da denne ikke kan åbne tilfældige filer.
Dette kan løses ved at skifte til en opdateret filhåndtering eller en app designet til de seneste Android-versioner. Alternativt kan FairEmail tildeles læserettighed til enhedens lagerplads i Android app-indstillingerne. Bemærk, at denne løsning [ikke længere fungerer på Android Q](https://developer.android.com/preview/privacy/scoped-storage).
Tjek også [spørgsmål 25](#user-content-faq25) og [hvad Google skriver om det](https://developer.android.com/training/secure-file-sharing/share-file#RespondToRequest).
**(50) Kan der blive tilføjet en mulighed for at synkronisere alle beskeder?**
En synkronisér alle (download alle) beskeder mulighed vil ikke blive tilføjet, da det nemt kan resultere i hukommelse opbrugt-fejl og den tilgængelige lagerplads opbruges. Det kan også nemt resultere i en masse batteri og dataforbrug. Mobilenheder er ikke særligt velegnede til download og lagring af beskeder for flere år. Funktionen søgningen på server vil være bedre (tjek [spørgsmål 13](#user-content-faq13)), da den er hurtigere og mere effektiv. Bemærk, at gennemsøgning af en masse lokalt lagrede beskeder kun ville forsinke søgning og forbruge ekstra strøm.
**(51) Hvordan sorteres mapper?**
Mapper sorteres først på efter konto (som standard på kontonavn) og indenfor en konto med specielle, systemmapper øverst, efterfulgt af mapper opsat til synkronisering. Inden for hver kategori sorteres mapperne efter (vist) navn. Om nødvendigt eller ønsket, kan dette ændres vha. langt tryk på en mappe i mappelisten og vælge *Redigér egenskaber*.
Navigation (hamburger-)menupunktet *Sortér mapper* i opsætningen kan bruges til manuelt at sortere mapperne.
**(52) Hvorfor tager det noget tid at genoprette forbindelsen til en konto?**
Der er ingen pålidelig måde at få oplyst, om en kontoforbindelse blev afsluttet tilsigtet eller utilsigtet. Forsøg på at genoprette forbindelse til en konto, hvor kontoforbindelsen for ofte blev afsluttet abrupt, kan resultere i problemer såsom [for mange samtidige forbindelser](#user-content-faq23) eller endda blokering af kontoen. For at forhindre sådanne problemer, afventer FairEmail 90 sek., inden forbendelsen igen forsøges genoprettet.
Benyt et langt tryk på *Indstillinger* i navigeringsmenuen for straks at genoprette forbindelsen.
**(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](https://jmap.io/) 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](https://en.wikipedia.org/wiki/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](https://en.wikipedia.org/wiki/ASCII_art), you should wrap the text in a *pre* element, like this:
```
|\_/|
/ @ @ \
( > º < )
`>>x<<´
/ O \
```
**(58) What does an open/closed email icon mean?**
The email icon in the folder list can be open (outlined) or closed (solid):
Message bodies and attachments are not downloaded by default.
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](https://developer.android.com/guide/topics/providers/document-provider) could be used to share these files, but even Google's Chrome cannot handle this.
**(60) Did you know ... ?**
* Did you know that starred messages can be synchronized/kept always? (this can be enabled in the receive settings)
* Did you know that you can long press the 'write message' icon to go to the drafts folder?
* Did you know there is an advanced option to mark messages read when they are moved? (archiving and trashing is also moving)
* Did you know that you can select text (or an email address) in any app on recent Android versions and let FairEmail search for it?
* Did you know that FairEmail has a tablet mode? Rotate your device in landscape mode and conversation threads will be opened in a second column if there is enough screen space.
* Did you know that you can long press a reply template to create a draft message from the template?
* Did you know that you can long press, hold and swipe to select a range of messages?
* Did you know that you can retry sending messages by using pull-down-to-refresh in the outbox?
* Did you know that you can swipe a conversation left or right to go to the next or previous conversation?
* Did you know that you can tap on an image to see where it will be downloaded from?
* Did you know that you can long press the folder icon in the action bar to select an account?
* Did you know that you can long press the star icon in a conversation thread to set a colored star?
* Did you know that you can open the navigation drawer by swiping from the left, even when viewing a conversation?
* Did you know that you can long press the people's icon to show/hide the CC/BCC fields and remember the visibility state for the next time?
* Did you know that you can insert the email addresses of an Android contact group via the three dots overflow menu?
* Did you know that if you select text and hit reply, only the selected text will be quoted?
* Did you know that you can long press the trash icons (both in the message and the bottom action bar) to permanently delete a message or conversation? (version 1.1368+)
* Did you know that you can long press the send action to show the send dialog, even if it was disabled?
* Did you know that you can long press the full screen icon to show the original message text only?
**(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](#user-content-faq3) 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](https://developers.google.com/gmail/imap/xoauth2-protocol), [Yandex](https://tech.yandex.com/oauth/))
* NTLM (untested)
SASL authentication methods, besides CRAM-MD5, are not supported because [JavaMail for Android](https://javaee.github.io/javamail/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](https://en.wikipedia.org/wiki/Server_Name_Indication) is supported by [all supported Android versions](https://developer.android.com/training/articles/security-ssl).
**(63) How are images resized for displaying on screens?**
Large inline or attached [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics) and [JPEG](https://en.wikipedia.org/wiki/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](https://f-droid.org/en/packages/mobi.omegacentauri.SendReduced/) 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](#user-content-faq55).~~
~~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](https://tools.ietf.org/html/rfc2183) are supposed to be downloaded and shown automatically, but since FairEmail doesn't always download attachments automatically, see also [this FAQ](#user-content-faq40), 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](#user-content-faq19), to justify making FairEmail available in the [Google Play Family Library](https://support.google.com/googleone/answer/7007852). 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](#user-content-faq71).
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](https://developer.android.com/guide/topics/providers/document-provider) 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](https://github.com/offa/android-foss#-document--pdf-viewer).~~
**(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:
* There is just one message in the conversation
* There is exactly one unread message in the conversation
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:
* Sender contains
* Recipient contains
* Subject contains
* Has attachments
* Header contains
* Day/time between
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" `
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](https://en.wikipedia.org/wiki/Regular_expression). Please see [here](https://developer.android.com/reference/java/util/regex/Pattern) for the documentation of Java regular expressions. You can test a regex [here](https://regexr.com/).
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](https://developer.android.com/reference/java/util/regex/Pattern#DOTALL) is enabled to be able to match [unfolded headers](https://tools.ietf.org/html/rfc2822#section-3.2.3).
You can select one of these actions to apply to matching messages:
* No action (useful for *not*)
* Mark as read
* Mark as unread
* Hide
* Suppress notification
* Snooze
* Add star
* Set importance (local priority)
* Add keyword
* Move
* Copy (Gmail: label)
* Answer/forward (with template)
* Text-to-speech (sender and subject)
* Automation (Tasker, etc)
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](https://tools.ietf.org/html/rfc3834)
* *.*Content-Type: multipart/report.** [RFC3462](https://tools.ietf.org/html/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](https://developer.android.com/topic/libraries/architecture/), 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](#user-content-faq71) 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](https://support.google.com/android/answer/9069335) 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](https://tasker.joaoapps.com/userguide/en/intents.html):
```
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](#user-content-faq24) 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](https://javaee.github.io/javamail/FAQ#imapserverbug) 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](https://en.wikipedia.org/wiki/Web_beacon) 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:
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](#user-content-faq31) 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:
* the identity is set to synchronize (send messages)
* the associated account is set to synchronize (receive messages)
* the associated account has a drafts folder
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:~~
* ~~Looking up the owner of the IP address of a link~~
* ~~Detection and removal of [tracking images](#user-content-faq82)~~
**(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:
* [for Yahoo](https://help.yahoo.com/kb/generate-third-party-passwords-sln15241.html)
* [for AOL](https://help.aol.com/articles/Create-and-manage-app-password)
* [for Sky](https://www.sky.com/help/articles/getting-started-with-sky-yahoo-mail) (under *Other email apps*)
Please see [this FAQ](#user-content-faq111) 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](https://en.wikipedia.org/wiki/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](https://en.wikipedia.org/wiki/List_of_Internet_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.
**~~(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](#user-content-faq39) about optimizing battery usage.~~
**(92) Can you add spam filtering, verification of the DKIM signature and SPF authorization?**
Spam filtering, verification of the [DKIM](https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail) signature and [SPF](https://en.wikipedia.org/wiki/Sender_Policy_Framework) 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.
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](#user-content-faq71) too. Blocking the sender will create a filter rule to automatically move future messages of the same sender into the spam folder.
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](https://en.wikipedia.org/wiki/DMARC) authentication failed on the receiving server. You can enable/disable [authentication verification](https://en.wikipedia.org/wiki/Email_authentication) 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](https://www.mail-tester.com/) 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](https://developer.android.com/guide/topics/data/install-location).
Messages, attachments, etc stored on external storage media, like an sdcard, can be accessed by other apps and is therefore not safe. See [here](https://developer.android.com/training/data-storage) 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](#user-content-faq92).
**(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](https://developer.android.com/guide/topics/providers/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](https://developer.android.com/preview/privacy/scoped-storage) and [here](https://www.xda-developers.com/android-q-storage-access-framework-scoped-storage/) 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](https://en.wikipedia.org/wiki/Formatted_text) or [Markdown](https://en.wikipedia.org/wiki/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](https://forum.xda-developers.com/showpost.php?p=79061829&postcount=4919) 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](https://en.wikipedia.org/wiki/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](https://en.wikipedia.org/wiki/JPEG) and [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics) 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](https://www.bugsnag.com/)
* Bugsnag for Android is [open source](https://github.com/bugsnag/bugsnag-android)
* See [here](https://docs.bugsnag.com/platforms/android/automatically-captured-data/) about what data will be sent in case of errors
* See [here](https://docs.bugsnag.com/legal/privacy-policy/) 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](https://en.wikipedia.org/wiki/European_Union_roaming_regulations#Territorial_extent) 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](https://github.com/leolin310148/ShortcutBadger#supported-launchers) 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](#user-content-faq2), 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](https://forum.xda-developers.com/android/general/bad-news-tesla-unread-devoloper-t3920415).
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](#user-content-faq71).
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](https://github.com/M66B/FairEmail/blob/master/README.md#downloads) for the options~~
* ~~Use app specific passwords, see [this FAQ](#user-content-faq6)~~
~~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](https://support.google.com/cloud/answer/9110914) ($15,000 to $75,000) for this. You can read more about this [here](https://www.theregister.com/2019/02/11/google_gmail_developer/).
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](https://restoreprivacy.com/secure-email/) or [Privacy Tools](https://www.privacytools.io/providers/email/) 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](#user-content-faq129) 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](#user-content-faq37).
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](https://material.io/design/components/chips.html) 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](https://github.com/M66B/FairEmail/commit/2c80c25b8aa75af2287f471b882ec87d5a5a5015).
**~~(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](https://support.google.com/googleplay/answer/1050566?hl=en)
* 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](https://support.google.com/googleplay/answer/1050566?hl=en)
* 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](https://en.wikipedia.org/wiki/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](https://developer.android.com/training/notify-user/group). 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](#user-content-faq70) 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](https://developer.android.com/training/monitoring-device-state/doze-standby) 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?**
* [IMAP NOTIFY](https://tools.ietf.org/html/rfc5465) support
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 needs to be enabled.
**Important**: most email server do not support this! You can check the log via the navigation menu if an email server supports the NOTIFY capability.
You can enable experimental features in the miscellaneous settings.
**(126) Can message previews be sent to my wearable?**
FairEmail fetches a message in two steps:
1. Fetch message headers
1. 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](https://protonmail.com/support/knowledge-base/imap-smtp-and-pop3-setup/), so you cannot use FairEmail to access ProtonMail.
Tutanota uses a proprietary email protocol and [does not support IMAP](https://tutanota.com/faq/#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](#user-content-faq22) 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](http://en.miui.com/thread-3930694-1-1.html) how you can fix this.
There is a bug in some Android versions causing [setOnlyAlertOnce](https://developer.android.com/reference/android/app/Notification.Builder#setOnlyAlertOnce(boolean)) 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](https://en.wikipedia.org/wiki/Exchange_ActiveSync#Licensing) 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](https://techcommunity.microsoft.com/t5/Exchange-Team-Blog/Upcoming-changes-to-Exchange-Web-Services-EWS-API-for-Office-365/ba-p/608055).
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](https://f-droid.org/packages/at.bitfire.davdroid/) app to synchronize/manage your calendars/contacts.
Most providers support exporting your contacts. Please [see here](https://support.google.com/contacts/answer/1069522) 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](#user-content-faq23) 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](https://en.wikipedia.org/wiki/ISO/IEC_8859-1) when no character set or when [US-ASCII](https://en.wikipedia.org/wiki/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](https://www.iana.org/assignments/imap-mailbox-name-attributes/imap-mailbox-name-attributes.xhtml) 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](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](#user-content-faq71) 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](https://en.wikipedia.org/wiki/Post_Office_Protocol) 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:
This requires a compatible audio recorder app to be installed. In particular [this common intent](https://developer.android.com/reference/android/provider/MediaStore.Audio.Media.html#RECORD_SOUND_ACTION) needs to be supported.
For example [this audio recorder](https://f-droid.org/app/com.github.axet.audiorecorder) 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](https://github.com/M66B/FairEmail/blob/master/README.md#user-content-downloads) 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](https://support.apple.com/en-us/HT202304).
When using two-factor authentication you might need to use an [app-specific password](https://support.apple.com/en-us/HT204397).
**(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](https://developer.android.com/guide/topics/providers/calendar-provider.html#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](https://imapsync.lamiral.info/).
If you want to import an mbox file to an existing email account, you can use Thunderbird on a desktop computer and the [ImportExportTools](https://addons.thunderbird.net/nl/thunderbird/addon/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](https://support.google.com/contacts/answer/30970) for instructions.
**(153) Why does permanently deleting Gmail message not work?**
You might need to change [the Gmail IMAP settings](https://mail.google.com/mail/u/0/#settings/fwdandpop) 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](https://en.wikipedia.org/wiki/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](https://en.wikipedia.org/wiki/Transport_Neutral_Encapsulation_Format)) containing a message and possibly attachments.
You can find some more information about this file [here](https://support.mozilla.org/en-US/kb/what-winmaildat-attachment).
You can view it with for example the Android app [Letter Opener](https://play.google.com/store/apps/details?id=app.letteropener).
**(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](https://docs.microsoft.com/en-in/exchange/troubleshoot/configure-mailboxes/pop3-imap-owa-activesync-office-365).
If you've enabled *security defaults* in your organization, you might need to enable the SMTP AUTH protocol. Please [see here](https://docs.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/authenticated-client-smtp-submission) about how to.
**(157) How can I set up an Free.fr account?**
Veuillez [voir ici](https://free.fr/assistance/597.html) pour les instructions.
**SMTP est désactivé par défaut**, veuillez [voir ici](https://free.fr/assistance/2406.html) comment il peut être activé.
Veuillez [voir ici](http://jc.etiemble.free.fr/abc/index.php/trucs-astuces/configurer-smtp-free-fr) 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:
* [Open Camera](https://play.google.com/store/apps/details?id=net.sourceforge.opencamera) ([F-Droid](https://f-droid.org/en/packages/net.sourceforge.opencamera/))
* [Audio Recorder version 3.3.24+](https://play.google.com/store/apps/details?id=com.github.axet.audiorecorder) ([F-Droid](https://f-droid.org/packages/com.github.axet.audiorecorder/))
To record voice notes, etc, the audio recorder needs to support [MediaStore.Audio.Media.RECORD_SOUND_ACTION](https://developer.android.com/reference/android/provider/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](https://disconnect.me/trackerprotection) 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](https://disconnect.me/trackerprotection#trackers-we-dont-block) 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](https://github.com/disconnectme/disconnect-tracking-protection/commits/master) 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](https://tools.ietf.org/html/rfc4315).
**(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](https://stackoverflow.com/a/26511725/1794097), so this is not possible.
## Get support
FairEmail is supported on smartphones, tablets and ChromeOS only.
Only the latest Play store version and latest GitHub release are supported. The F-Droid build is supported only if the version number is the same as the version number of the latest GitHub release. This also means that downgrading is not supported.
There is no support on things that are not directly related to FairEmail.
There is no support on building and developing things by yourself.
Requested features should:
* be useful to most people
* not complicate the usage of FairEmail
* fit within the philosophy of FairEmail (privacy oriented, security minded)
* comply with common standards (IMAP, SMTP, etc)
Features not fulfilling these requirements will likely be rejected. This is also to keep maintenance and support in the long term feasible.
If you have a question, want to request a feature or report a bug, please use [this form](https://contact.faircode.eu/?product=fairemailsupport).
GitHub issues are disabled due to frequent misusage.
