You can use the quick setup wizard to easily setup a Gmail account and identity.
If you use the Play store or GitHub version of FairEmail, you can use the quick setup wizard to easily setup a Gmail account and identity. The Gmail quick setup wizard is not available for third party builds, like the F-Droid build because Google approved the use of OAuth for official builds only.
If you don't want to use an on-device Gmail account, you can either enable access for "less secure apps" and use your account password (not advised) or enable two factor authentication and use an app specific password. To use a password you'll need to setup an account and identity via setup step 1 and 2 instead of via the quick setup wizard.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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.

A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. This will work best with similar messages.

The message classifier calculates the probability a message belongs in a folder (class). There are two options in miscellaneous settings that control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
* *Minimum class probability*: the minimum chance a message belongs in a folder (default 20 %)
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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.

The message classifier calculates the probability a message belongs in a folder (class). There are two options in miscellaneous settings that control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
* *Minimum class probability*: the minimum chance a message belongs in a folder (default 20 %)
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)
Both conditions must be satisfied before a message will be moved.

If you use the Play store or GitHub version of FairEmail, you can use the quick setup wizard to easily setup a Gmail account and identity. The Gmail quick setup wizard is not available for third party builds, like the F-Droid build because Google approved the use of OAuth for official builds only.
If you don't want to use an on-device Gmail account, you can either enable access for "less secure apps" and use your account password (not advised) or enable two factor authentication and use an app specific password.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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 the POP3 protocol gives access to the inbox only. So, it is won't be possible to report spam for POP3 accounts.

Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder.

If you don't want to use an on-device Gmail account, you can either enable access for "less secure apps" and use your account password (not advised) or enable two factor authentication and use an app specific password. To use a password you'll need to setup an account and identity via setup step 1 and 2 instead of via the quick setup wizard.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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.

A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. This will work best with similar messages.

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

**(13) How does search on device/server work?**
**(13) Hvordan fungerer søgning på en enhed/server?**
You can start searching for messages on sender (from), recipient (to, cc, bcc), subject, keywords or message text by using the magnify glass in the action bar of a folder. You can also search from any app by selecting *Search email* in the copy/paste popup menu.
Beskedsøgning kan foretages efter Afsender (fra), Modtager (til, kopi, bcc), Emne, nøgleord eller beskedtekst via forstørrelsesglasset i en mappes handlingsbjælke. Søgning kan også ske fra enhver app ved at vælge *Søg efter e-mail * i popup-menuen kopiér/indsæt.
Searching in the unified inbox will search in all folders of all accounts, searching in the folder list will search in the associated account only and searching in a folder will search in that folder only.
Søgning i den fælles indbakke udføres i alle mapper på alle konti, søgning i mappelisten udføres kun for den tilknyttede konto og søgning i en mappe udføres kun i dén mappe.
Messages will be searched for on the device first. There will be an action button with a search again icon at the bottom to continue searching on the server. You can select in which folder to continue the search.
Beskedsøging sker indledningsvis på enheden. For at fortsætte søgningen på serveren, brug handlingsknappen nederst med ikonet Søg igen. Man kan vælge, i hvilken mappe søgningen skal fortsættes.
The IMAP protocol doesn't support searching in more than one folder at the same time. Searching on the server is an expensive operation, therefore it is not possible to select multiple folders.
IMAP-protokollen understøtter kun søgning i én mappe ad gangen. Serversøgning er ressourcekrævende og derfor uden mulighed for valg af flere mapper.
Searching local messages is case insensitive and on partial text. The message text of local messages will not be searched if the message text was not downloaded yet. Searching on the server might be case sensitive or case insensitive and might be on partial text or whole words, depending on the provider.
Søgning i lokale beskeder er versal/minuskel ufølsom på deltekst. Lokale beskedtekster gennemsøges kun, såfremt selve beskedteksterne allerede er downloadet. Serversøgning kan være både versal/minuskel følsom eller ufølsom og kan, afhængigt af udbyderen, være på deltekst eller hele ord.
Some servers cannot handle searching in the message text when there are a large number of messages. For this case there is an option to disable searching in the message text.
Visse servere kan ikke håndtere søgning i beskedtekster ifm. et stort beskedantal. For sådanne tilfælde findes en mulighed for at deaktivere søgning i beskedtekster.
It is possible to use Gmail search operators by prefixing a search command with *raw:*. If you configured just one Gmail account, you can start a raw search directly on the server by searching from the unified inbox. If you configured multiple Gmail accounts, you'll first need to navigate to the folder list or the archive (all messages) folder of the Gmail account you want to search in. Please [see here](https://support.google.com/mail/answer/7190) for the possible search operators. For example:
Det er muligt at bruge Gmail-søgeoperatører vha. søgekommandopræfikset *raw:*. Er kun én Gmail-konto opsat, kan en raw søgning startes direkte på serveren ved at søge i den fælles indbakke. Er flere Gmail-konti opsat, skal man først gå til mappelisten eller arkivmappen (alle beskeder) for den Gmail-konto, der skal gennemsøges. [Tjek hér](https://support.google.com/mail/answer/7190) ang. de mulige søgeoperatører. F.eks.:
`
`
raw:larger:10M`
raw:larger:10M`
Searching through a large number of messages on the device is not very fast because of two limitations:
Gennemsøgning af et stort beskedantal på enheden sker ikke særligt hurtigt grundet to begrænsninger:
* [sqlite](https://www.sqlite.org/), Androids databasemotor har en poststørrelsesbegrænsning, der forhindrer, at beskedtekster gemmes i databasen
* [sqlite](https://www.sqlite.org/), Androids databasemotor har en poststørrelsesbegrænsning, der forhindrer, at beskedtekster gemmes i databasen
* Android-apps får kun begrænset hukommelse at arbejde med, selv hvis enheden har masser af hukommelse til rådighed
* Android-apps får kun begrænset hukommelse at arbejde med, selv hvis enheden har masser af hukommelse til rådighed
This means that searching for a message text requires that files containing the message texts need to be opened one by one to check if the searched text is contained in the file, which is a relatively expensive process.
Dette betyder, at søgning efter en beskedtekst i adskillige filer kræver, at disse filer åbnes/tjekkes én for én, hvilket er en relativt ressourcekrævende proces.
In the *miscellaneous settings* you can enable *Build search index* to significantly increase the speed of searching on the device, but be aware that this will increase battery and storage space usage. The search index is based on words, so searching for partial text is not possible. Searching using the search index is by default AND, so searching for *apple orange* will search for apple AND orange. Words separated by commas result in searching for OR, so for example *apple, orange* will search for apple OR orange. Both can be combined, so searching for *apple, orange banana* will search for apple OR (orange AND banana). Using the search index is a pro feature.
Under *Diverse indstillinger* kan *Byg søgeindeks* aktiveres for markant at øge søgehastigheden på enheden (øger dog samtidigt også både strøm- og lagerpladsforbrug). Søgeindekset er baseret på ord, så deltekstsøgning er ikke muligt. Søgning vha. søgeindekset er som standard OG (AND), så søgning efter f.eks. *æble appelsin* vil søge efter både æble OG appelsin. Words separated by commas result in searching for OR, so for example *apple, orange* will search for apple OR orange. Both can be combined, so searching for *apple, orange banana* will search for apple OR (orange AND banana). Using the search index is a pro feature.
From version 1.1315 it is possible to use search expressions like this:

**Generelle fejl**
The error *... Authentication failed ...* or *... AUTHENTICATE failed ...* likely means that your username or password was incorrect. Some providers expect as username just *username* and others your full email address *username@example.com*. When copying/pasting to enter a username or password, invisible characters might be copied, which could cause this problem as well. Some password managers are known to do this incorrectly too. The username might be case sensitive, so try lowercase characters only. The password is almost always case sensitive. Some providers require using an app password instead of the account password, so please check the documentation of the provider. Sometimes it is necessary to enable external access (IMAP/SMTP) on the website of the provider first. Other possible causes are that the account is blocked or that logging in has been administratively restricted in some way, for example by allowing to login from certain networks / IP addresses only.
Fejlen *... Godkendelse mislykkedes ...* eller *... GODKENDELSE mislykkedes ...* skyldes sandsynligvis forkert brugernavn/adgangskode.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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 the POP3 protocol gives access to the inbox only. So, it is won't be possible to report spam for POP3 accounts.

**(163) What is message classification?**
**(163) What is message classification?**
*Dette er en eksperimentel funktion!*
*This is an experimental feature!*
Beskedklassificering vil forsøge automatisk at gruppere e-mails i klasser baseret på deres indhold vha. [Bayesian-statistik](https://en.wikipedia.org/wiki/Bayesian_statistics). I FairEmail-kontekst udgør en mappe en klasse. Så f.eks. indbakken, Spam-mappen, en 'markedsføringsmappe' mv.
Message classification will attempt to automatically group emails into classes, based on their contents, using [Bayesian statistics](https://en.wikipedia.org/wiki/Bayesian_statistics). In the context of FairEmail, a folder is a class. So, for example, the inbox, the spam folder, a 'marketing' folder, etc, etc.
Beskedklassificering kan aktiveres under diverse indstillinger. Dette aktiverer kun læringstilstand.
You can enable message classification in the miscellaneous settings. This will enable 'learning mode' only.
Hver mappe har en mulighed for at aktivere automatisk beskedklassificering. Når dette er slået til, vil nye beskeder i andre mapper, som klassifikatoren mener hører til den mappe, automatisk blive flyttet.
Each folder has an option to enable automatic message classification. When this is turned on, new messages in other folders which the classifier thinks belong to that folder will be automatically moved.
Indstillingen *Brug lokalt spamfilter* i spamdialogen slår besked- og autoklassificering til for Spam-mappen. Bemærk dog, at dette ikke er en erstatning for e-mailserverens spamfilter og kan give falske positivresultater. Tjek også [denne FAQ](#user-content-faq92).
The option *Use local spam filter* in the report spam dialog will turn on message classification in the miscellaneous settings and auto classification for the spam folder. Please understand that this is not a replacement for the spam filter of the email server and can result in [false positives and false negatives](https://en.wikipedia.org/wiki/False_positives_and_false_negatives). See also [this FAQ](#user-content-faq92).
Et praktisk eksempel: Antag, at mappen 'markedsføring' findes og automatisk beskedklassificering er aktiveret for denne. Hver gang en besked flyttes til denne mappe, trænes FairEmail i, at lignende beskeder hører til hér. Hver gang en besked flyttes fra denne mappe, trænes FairEmail i, at lignende beskeder ikke hører til hér. Efter at have flyttet nogle beskeder til mappen, vil FairEmail automatisk begynde at flytte beskeder hertil. Dette vil fungere bedst med similære beskeder.
A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the 'marketing' folder, FairEmail will start moving similar messages automatically into this folder. Or, the other way around, after moving some messages out of the 'marketing' folder, FairEmail will stop moving similar messages automatically into this folder. This will work best with messages with similar content (email addresses, subject and message text).
Klassificering bør betragtes som et bedste gæt - det kan være et forkert gæt, eller klassifikatoren er måske for usikker til at foretage gæt. Er klassificatoren usikker, lader den blot en e-mail blive, hvor den er.
Classification should be considered as a best guess - it might be a wrong guess, or the classifier might not be confident enough to make any guess. If the classifier is unsure, it will simply leave an email where it is.
Klassificering udføres kun på nye beskeder i indbakken og Spam-/brugermapper. Lokale beskeder kan rryddes (langt tryk på en kontos mappe i mappelisten) og herefter gensynkroniseres for at klassificere beskederne.
Classification will be done for new messages in the inbox, spam folder and user folders only. You can clear local messages (long press a folder in the folder list of an account) and synchronize the messages again to classify existing messages.
Flytning af en besked på enheden vil omklassificere denne. Moving a message with another email client will not result in reclassification because IMAP does not support 'moved' notifications.
To prevent the email server from moving a message into the spam folder again and again, auto classification out of the spam folder will not be done.
For at forhindre e-mailserveren i at flytte en besked til Spam-mappen igen og igen, vil autoklassificering ud af Spam-mappen ikke ske.
The message classifier calculates the probability a message belongs in a folder (class). There are two options in miscellaneous settings that control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
Beskedklassifikatoren beregner sandsynligheden for, at en besked hører til i en mappe (klasse). Der er to indstillinger i diverse indstillingerne, som styrer, om en besked autoflyttes til en mappe, for hvilken autoklassificering er aktiveret:
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)
* *Minimumsklassesandsynlighed*: Minimumssandsynligheden for, at en besked hører til i en mappe (standard 20%)
Both conditions must be satisfied before a message will be moved.
* *Minimumsklasseforskel*: Minimumsforskellen ift. den næstbedste mappe (standard 50%)
Overvejelse af standardindstillingsværdier:
Considering the defaults option values:
* Æbler 40% og bananer 30% vil blive tilsidesat, da forskellen på 25% ligger under et minimum på 50%
* Æbler 40% og bananer 30% vil blive tilsidesat, da forskellen på 25% ligger under et minimum på 50%
* Æbler 15% og bananer 5% vil blive tilsidesat, da sandsynligheden for æbker er under et minimum på 20%
* Æbler 15% og bananer 5% vil blive tilsidesat, da sandsynligheden for æbker er under et minimum på 20%
* Æbler 50% og bananer 20% vil resultere i valg af æbler
* Æbler 50% og bananer 20% vil resultere i valg af æbler
Klassificeringen er optimeret til brug af så få ressourcer som muligt, men vil uundgåeligt bruge ekstra strøm.
Classification is optimized to use as little resources as possible, but will inevitably use some extra battery power.
You can delete all classification data by turning classification three times off.
[Filter rules](#user-content-faq71) will be executed before classification.
Alle klassificeringsdata kan slettes ved at slå klassificeringen fra tre gange.
Message classification is a pro feature, except for the spam folder.

A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. Dies funktioniert am besten bei ähnlichen Nachrichten.

Or, the other way around, after moving some messages out of the 'marketing' folder, FairEmail will stop moving similar messages automatically into this folder. This will work best with messages with similar content (email addresses, subject and message text).
Classification should be considered as a best guess - it might be a wrong guess, or the classifier might not be confident enough to make any guess. If the classifier is unsure, it will simply leave an email where it is.

Classification will be done for new messages in the inbox, spam folder and user folders only. You can clear local messages (long press a folder in the folder list of an account) and synchronize the messages again to classify existing messages.

The message classifier calculates the probability a message belongs in a folder (class). There are two options in miscellaneous settings that control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
* *Minimum class probability*: the minimum chance a message belongs in a folder (default 20 %)
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)
Both conditions must be satisfied before a message will be moved.

A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. This will work best with similar messages.

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

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

* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)

Message classification will attempt to automatically group emails into classes, based on their contents, using [Bayesian statistics](https://en.wikipedia.org/wiki/Bayesian_statistics). In the context of FairEmail, a folder is a class. So, for example, the inbox, the spam folder, a 'marketing' folder, etc, etc.

The option *Use local spam filter* in the report spam dialog turns on message classification and auto classification for the spam folder. Please understand that this is not a replacement for the spam filter of the email server and can result in false positives. See also [this FAQ](#user-content-faq92).

A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. This will work best with similar messages.

Or, the other way around, after moving some messages out of the 'marketing' folder, FairEmail will stop moving similar messages automatically into this folder. This will work best with messages with similar content (email addresses, subject and message text).
Classification should be considered as a best guess - it might be a wrong guess, or the classifier might not be confident enough to make any guess. If the classifier is unsure, it will simply leave an email where it is.

Classification will be done for new messages in the inbox, spam folder and user folders only. You can clear local messages (long press a folder in the folder list of an account) and synchronize the messages again to classify existing messages.

Moving a message on the device will reclassify the message. Moving a message with another email client will not result in reclassification because IMAP does not support 'moved' notifications.

The message classifier calculates the probability a message belongs in a folder (class). There are two options in miscellaneous settings that control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
* *Minimum class probability*: the minimum chance a message belongs in a folder (default 20 %)
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)
Both conditions must be satisfied before a message will be moved.

You can use the quick setup wizard to easily setup a Gmail account and identity.
If you use the Play store or GitHub version of FairEmail, you can use the quick setup wizard to easily setup a Gmail account and identity. The Gmail quick setup wizard is not available for third party builds, like the F-Droid build because Google approved the use of OAuth for official builds only.
If you don't want to use an on-device Gmail account, you can either enable access for "less secure apps" and use your account password (not advised) or enable two factor authentication and use an app specific password. To use a password you'll need to setup an account and identity via setup step 1 and 2 instead of via the quick setup wizard.

You can use the button *Manage notifications* in the setup to directly go to the Android notification settings. Note that apps cannot change notification settings, including the notification light setting, on Android 8 Oreo and later anymore. Apps designed and targeting older Android versions might still be able to control the contents of notifications, but such apps cannot be updated anymore and recent Android versions will show a warning that such apps are outdated.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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.

**(6) How can I login to Gmail / G suite?**
**(6) Comment puis-je me connecter à Gmail / G suite ?**
You can use the quick setup wizard to easily setup a Gmail account and identity.
Si vous utilisez la version Play Store ou GitHub de FairEmail, vous pouvez utiliser l'assistant de configuration rapide pour configurer facilement un compte Gmail et une identité. L'assistant de configuration rapide de Gmail n'est pas disponible pour les versions tierces, comme la version F-Droid, car Google n'a approuvé l'utilisation d'OAuth que pour les versions officielles.
If you don't want to use an on-device Gmail account, you can either enable access for "less secure apps" and use your account password (not advised) or enable two factor authentication and use an app specific password. To use a password you'll need to setup an account and identity via setup step 1 and 2 instead of via the quick setup wizard.
Si vous ne souhaitez pas utiliser le compte Gmail de l'appareil, vous pouvez soit autoriser l'accès aux "applications moins sécurisées" et utiliser le mot de passe de votre compte (déconseillé) ou activer l'authentification à deux facteurs et utiliser un mot de passe spécifique à l'application. Pour utiliser un mot de passe, vous devrez configurer un compte et une identité via les étapes de configuration 1 et 2, au lieu de passer par l'assistant de configuration rapide.
Please see [this FAQ](#user-content-faq111) on why only on-device accounts can be used.
Veuillez consulter [cette FAQ](#user-content-faq111) pour savoir pourquoi seuls les comptes de l'appareil peuvent être utilisés.
Note that an app specific password is required when two factor authentication is enabled.
Notez qu'un mot de passe spécifique à l'application est nécessaire lorsque l'authentification à deux facteurs est activée.

**Important**: using this method is not recommended because it is less reliable.

If you use multiple Gmail accounts, make sure you change the "less secure apps" setting of the right account(s).
Si vous utilisez plusieurs comptes Gmail, assurez-vous de modifier le paramètre "Autoriser les applications moins sécurisées" du ou des comptes concernés.
Be aware that you need to leave the "less secure apps" settings screen by using the back arrow to apply the setting.
Sachez que vous devez quitter l'écran de paramétrage des "applications moins sécurisées" en utilisant la flèche de retour arrière pour que le paramètre soit appliqué.
If you use this method, you should use a [strong password](https://en.wikipedia.org/wiki/Password_strength) for your Gmail account, which is a good idea anyway. Note that using the [standard](https://tools.ietf.org/html/rfc3501) IMAP protocol in itself is not less secure.
Si vous utilisez cette méthode, vous devriez utiliser un [mot de passe robuste](https://en.wikipedia.org/wiki/Password_strength) pour votre compte Gmail, ce qui est de toute façon une bonne idée. Notez que l'utilisation du protocole [standard](https://tools.ietf.org/html/rfc3501) IMAP n'est en soi pas moins sécurisée.
When "less secure apps" is not enabled, you'll get the error *Authentication failed - invalid credentials* for accounts (IMAP) and *Username and Password not accepted* for identities (SMTP).
Lorsque les "applications moins sécurisées" ne sont pas activées, vous obtiendrez l'erreur *L'authentification a échoué - identifiants non valides* pour les comptes (IMAP) et *nom d'utilisateur et mot de passe non acceptés* pour les identités (SMTP).

You might get the alert "*Please log in via your web browser*". This happens when Google considers the network that connects you to the internet (this could be a VPN) to be unsafe. This can be prevented by using the Gmail quick setup wizard or an app specific password.
Il se peut que vous obteniez l'alerte "*S'il vous plaît connectez-vous via votre navigateur web*". Cela se produit lorsque Google considère que le réseau sur lequel vous vous connectez à Internet (il peut s'agir d'un VPN) n'est pas sûr. Cela peut être évité en utilisant l'assistant de configuration rapide de Gmail ou un mot de passe spécifique à l'application.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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 the POP3 protocol gives access to the inbox only. So, it is won't be possible to report spam for POP3 accounts.
Note that you should not delete spam messages, also not from the spam folder, because the email server uses the messages in the spam folder to "learn" what spam messages are.

The option *Use local spam filter* in the report spam dialog turns on message classification and auto classification for the spam folder.

See also [this FAQ](#user-content-faq92).
A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. This will work best with similar messages.

Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder.

Or, the other way around, after moving some messages out of the 'marketing' folder, FairEmail will stop moving similar messages automatically into this folder. This will work best with messages with similar content (email addresses, subject and message text).
Classification should be considered as a best guess - it might be a wrong guess, or the classifier might not be confident enough to make any guess. If the classifier is unsure, it will simply leave an email where it is.

Moving a message on the device will reclassify the message. Moving a message with another email client will not result in reclassification because IMAP does not support 'moved' notifications.

**(6) How can I login to Gmail / G suite?**
**(6) Comment puis-je me connecter à Gmail / G suite ?**
You can use the quick setup wizard to easily setup a Gmail account and identity.
Si vous utilisez la version Play Store ou GitHub de FairEmail, vous pouvez utiliser l'assistant de configuration rapide pour configurer facilement un compte Gmail et une identité. L'assistant de configuration rapide de Gmail n'est pas disponible pour les versions tierces, comme la version F-Droid, car Google n'a approuvé l'utilisation d'OAuth que pour les versions officielles.
If you don't want to use an on-device Gmail account, you can either enable access for "less secure apps" and use your account password (not advised) or enable two factor authentication and use an app specific password. To use a password you'll need to setup an account and identity via setup step 1 and 2 instead of via the quick setup wizard.
Si vous ne souhaitez pas utiliser le compte Gmail de l'appareil, vous pouvez soit autoriser l'accès aux "applications moins sécurisées" et utiliser le mot de passe de votre compte (déconseillé) ou activer l'authentification à deux facteurs et utiliser un mot de passe spécifique à l'application. Pour utiliser un mot de passe, vous devrez configurer un compte et une identité via les étapes de configuration 1 et 2, au lieu de passer par l'assistant de configuration rapide.
Please see [this FAQ](#user-content-faq111) on why only on-device accounts can be used.
Veuillez consulter [cette FAQ](#user-content-faq111) pour savoir pourquoi seuls les comptes de l'appareil peuvent être utilisés.
Note that an app specific password is required when two factor authentication is enabled.
Notez qu'un mot de passe spécifique à l'application est nécessaire lorsque l'authentification à deux facteurs est activée.

See [here](https://support.google.com/accounts/answer/185833) about how to generate an app specific password.

*Enable "Less secure apps"*
*Autoriser les "Applications moins sécurisées"*
**Important**: using this method is not recommended because it is less reliable.
**Important**: l'utilisation de cette méthode n'est pas recommandée car elle est moins fiable.
**Important**: Gsuite accounts authorized with a username/password will stop working [in the near future](https://gsuiteupdates.googleblog.com/2019/12/less-secure-apps-oauth-google-username-password-incorrect.html).
**Important**: Les comptes Gsuite autorisés avec un nom d'utilisateur/mot de passe cesseront de fonctionner [dans un avenir proche](https://gsuiteupdates.googleblog.com/2019/12/less-secure-apps-oauth-google-username-password-incorrect.html).
See [here](https://support.google.com/accounts/answer/6010255) about how to enable "less secure apps" or go [directy to the setting](https://www.google.com/settings/security/lesssecureapps).
Voir [ici](https://support.google.com/accounts/answer/6010255) comment autoriser les "applications moins sécurisées" ou aller [directement au paramètre en question](https://www.google.com/settings/security/lesssecureapps).
If you use multiple Gmail accounts, make sure you change the "less secure apps" setting of the right account(s).
Si vous utilisez plusieurs comptes Gmail, assurez-vous de modifier le paramètre "Autoriser les applications moins sécurisées" du ou des comptes concernés.
Be aware that you need to leave the "less secure apps" settings screen by using the back arrow to apply the setting.
Sachez que vous devez quitter l'écran de paramétrage des "applications moins sécurisées" en utilisant la flèche de retour arrière pour que le paramètre soit appliqué.
If you use this method, you should use a [strong password](https://en.wikipedia.org/wiki/Password_strength) for your Gmail account, which is a good idea anyway. Note that using the [standard](https://tools.ietf.org/html/rfc3501) IMAP protocol in itself is not less secure.
Si vous utilisez cette méthode, vous devriez utiliser un [mot de passe robuste](https://en.wikipedia.org/wiki/Password_strength) pour votre compte Gmail, ce qui est de toute façon une bonne idée. Notez que l'utilisation du protocole [standard](https://tools.ietf.org/html/rfc3501) IMAP n'est en soi pas moins sécurisée.
When "less secure apps" is not enabled, you'll get the error *Authentication failed - invalid credentials* for accounts (IMAP) and *Username and Password not accepted* for identities (SMTP).
Lorsque les "applications moins sécurisées" ne sont pas activées, vous obtiendrez l'erreur *L'authentification a échoué - identifiants non valides* pour les comptes (IMAP) et *nom d'utilisateur et mot de passe non acceptés* pour les identités (SMTP).

You might get the alert "*Please log in via your web browser*". This happens when Google considers the network that connects you to the internet (this could be a VPN) to be unsafe. This can be prevented by using the Gmail quick setup wizard or an app specific password.
Il se peut que vous obteniez l'alerte "*S'il vous plaît connectez-vous via votre navigateur web*". Cela se produit lorsque Google considère que le réseau sur lequel vous vous connectez à Internet (il peut s'agir d'un VPN) n'est pas sûr. Cela peut être évité en utilisant l'assistant de configuration rapide de Gmail ou un mot de passe spécifique à l'application.

Sent messages are normally moved from the outbox to the sent folder as soon as your provider adds sent messages to the sent folder. This requires a sent folder to be selected in the account settings and the sent folder to be set to synchronizing.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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 the POP3 protocol gives access to the inbox only. So, it is won't be possible to report spam for POP3 accounts.
Note that you should not delete spam messages, also not from the spam folder, because the email server uses the messages in the spam folder to "learn" what spam messages are.

Message classification will attempt to automatically group emails into classes, based on their contents, using [Bayesian statistics](https://en.wikipedia.org/wiki/Bayesian_statistics). In the context of FairEmail, a folder is a class. So, for example, the inbox, the spam folder, a 'marketing' folder, etc, etc.

The option *Use local spam filter* in the report spam dialog turns on message classification and auto classification for the spam folder.

A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. This will work best with similar messages.

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

Classification will be done for new messages in the inbox, spam folder and user folders only. You can clear local messages (long press a folder in the folder list of an account) and synchronize the messages again to classify existing messages.

Moving a message on the device will reclassify the message. Moving a message with another email client will not result in reclassification because IMAP does not support 'moved' notifications.

The message classifier calculates the probability a message belongs in a folder (class). There are two options in miscellaneous settings that control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)
* *Minimum class probability*: the minimum chance a message belongs in a folder (default 20 %)
Both conditions must be satisfied before a message will be moved.

Please understand that this is not a replacement for the spam filter of the email server and can result in false positives. See also [this FAQ](#user-content-faq92).
The option *Use local spam filter* in the report spam dialog will turn on message classification in the miscellaneous settings and auto classification for the spam folder.

A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. This will work best with similar messages.

This will work best with messages with similar content (email addresses, subject and message text).
Classification should be considered as a best guess - it might be a wrong guess, or the classifier might not be confident enough to make any guess. If the classifier is unsure, it will simply leave an email where it is.

Classification will be done for new messages in the inbox, spam folder and user folders only. You can clear local messages (long press a folder in the folder list of an account) and synchronize the messages again to classify existing messages.

Moving a message on the device will reclassify the message. Moving a message with another email client will not result in reclassification because IMAP does not support 'moved' notifications.

The message classifier calculates the probability a message belongs in a folder (class). There are two options in miscellaneous settings that control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
* *Minimum class probability*: the minimum chance a message belongs in a folder (default 20 %)
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)
Both conditions must be satisfied before a message will be moved.

After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. This will work best with similar messages.
A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the 'marketing' folder, FairEmail will start moving similar messages automatically into this folder. Or, the other way around, after moving some messages out of the 'marketing' folder, FairEmail will stop moving similar messages automatically into this folder. This will work best with messages with similar content (email addresses, subject and message text).
Classification should be considered as a best guess - it might be a wrong guess, or the classifier might not be confident enough to make any guess. If the classifier is unsure, it will simply leave an email where it is.

Classification will be done for new messages in the inbox, spam folder and user folders only. You can clear local messages (long press a folder in the folder list of an account) and synchronize the messages again to classify existing messages.

Moving a message on the device will reclassify the message. Moving a message with another email client will not result in reclassification because IMAP does not support 'moved' notifications.

The message classifier calculates the probability a message belongs in a folder (class). There are two options in miscellaneous settings that control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
* *Minimum class probability*: the minimum chance a message belongs in a folder (default 20 %)
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)
Both conditions must be satisfied before a message will be moved.

This can be done automatically with [filter rules](#user-content-faq71) too.

The message classifier calculates the probability a message belongs in a folder (class). There are two options in miscellaneous settings that control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
* *Minimum class probability*: the minimum chance a message belongs in a folder (default 20 %)
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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.

The message classifier calculates the probability a message belongs in a folder (class). There are two options in miscellaneous settings that control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
* *Minimum class probability*: the minimum chance a message belongs in a folder (default 20 %)
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)
Both conditions must be satisfied before a message will be moved.

If you use the Play store or GitHub version of FairEmail, you can use the quick setup wizard to easily setup a Gmail account and identity. The Gmail quick setup wizard is not available for third party builds, like the F-Droid build because Google approved the use of OAuth for official builds only.
If you don't want to use an on-device Gmail account, you can either enable access for "less secure apps" and use your account password (not advised) or enable two factor authentication and use an app specific password.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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 the POP3 protocol gives access to the inbox only. So, it is won't be possible to report spam for POP3 accounts.

Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder.

If you use the Play store or GitHub version of FairEmail, you can use the quick setup wizard to easily setup a Gmail account and identity. The Gmail quick setup wizard is not available for third party builds, like the F-Droid build because Google approved the use of OAuth for official builds only.
If you don't want to use an on-device Gmail account, you can either enable access for "less secure apps" and use your account password (not advised) or enable two factor authentication and use an app specific password. To use a password you'll need to setup an account and identity via setup step 1 and 2 instead of via the quick setup wizard.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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 the POP3 protocol gives access to the inbox only. So, it is won't be possible to report spam for POP3 accounts.

A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. This will work best with similar messages.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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.

A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. This will work best with similar messages.

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

**(126) Можно ли отправлять предпросмотр сообщений на моём носителе?**
**(126) Can message previews be sent to my wearable?**
FairEmail получает сообщение в два этапа:
FairEmail fetches a message in two steps:
1. Fetch message headers
1. Fetch message headers
1. Fetch message text and attachments
1. Fetch message text and attachments
Непосредственно после первого шага будут уведомления о новых сообщениях. Однако, только после второго шага будет доступен текст сообщения. FairEmail обновляется при выходе из уведомлений с предварительным просмотром текста сообщения, но, к сожалению, поддерживаемые уведомления не могут быть обновлены.
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.
Поскольку нет гарантии того, что текст сообщения всегда будет загружен непосредственно после заголовка сообщения, невозможно гарантировать, что новое уведомление с предварительным текстом всегда будет отправлено на носимое значение.
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.
Если вы думаете, что это достаточно хорошо, вы можете включить опцию уведомления *Отправлять уведомления только с предпросмотром сообщений на носимые устройства* и если это не работает, вы можете включить опцию уведомлений *Показывать уведомления только с текстом предварительного просмотра*. Обратите внимание, что это относится к носимым файлам и не показывает предварительный текст, даже если приложение Android Wear говорит, что уведомление было отправлено (соединение мостом).
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).
Если вы хотите отправить полный текст сообщения в ваше носимое устройство, вы можете включить опцию уведомления *Предпросмотр всего текста*. Обратите внимание, что некоторые носители могут быть повреждены при включенной опции.
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.
Если вы используете носитель Samsung с приложением Galaxy Learable (Samsung Gear), вам может потребоваться включить уведомления для FairEmail , когда параметр *Уведомления*, *Приложения, установленные в будущем,* отключены в этом приложении.
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.

Moving a message on the device will reclassify the message. Moving a message with another email client will not result in reclassification because IMAP does not support 'moved' notifications.

The message classifier calculates the probability a message belongs in a folder (class). There are two options in miscellaneous settings that control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
* *Minimum class probability*: the minimum chance a message belongs in a folder (default 20 %)
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)
Both conditions must be satisfied before a message will be moved.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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.

* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)
Both conditions must be satisfied before a message will be moved.

If you use the Play store or GitHub version of FairEmail, you can use the quick setup wizard to easily setup a Gmail account and identity. The Gmail quick setup wizard is not available for third party builds, like the F-Droid build because Google approved the use of OAuth for official builds only.
If you don't want to use an on-device Gmail account, you can either enable access for "less secure apps" and use your account password (not advised) or enable two factor authentication and use an app specific password.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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.

Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder.

If you use the Play store or GitHub version of FairEmail, you can use the quick setup wizard to easily setup a Gmail account and identity. The Gmail quick setup wizard is not available for third party builds, like the F-Droid build because Google approved the use of OAuth for official builds only.
If you don't want to use an on-device Gmail account, you can either enable access for "less secure apps" and use your account password (not advised) or enable two factor authentication and use an app specific password. To use a password you'll need to setup an account and identity via setup step 1 and 2 instead of via the quick setup wizard.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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 the POP3 protocol gives access to the inbox only. So, it is won't be possible to report spam for POP3 accounts.
Note that you should not delete spam messages, also not from the spam folder, because the email server uses the messages in the spam folder to "learn" what spam messages are.

A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. This will work best with similar messages.

Before Android 8 Oreo: there is an advanced option in the notification settings of the app for this.
Android 8 Oreo and later: see [here](https://developer.android.com/training/notify-user/channels) about how to configure notification channels. You can use the button *Manage notifications* in the setup to directly go to the Android notification settings. Note that apps cannot change notification settings, including the notification light setting, on Android 8 Oreo and later anymore. Apps designed and targeting older Android versions might still be able to control the contents of notifications, but such apps cannot be updated anymore and recent Android versions will show a warning that such apps are outdated.
Android 8 Oreo and later: please see [here](https://developer.android.com/training/notify-user/channels) about how to configure notification channels. You can use the button *Default channel* in the notification settings of the app to directly go to the right Android notification channel settings.
Sometimes it is necessary to disable the setting *Show message preview in notifications* or to enable the settings *Show notifications with a preview text only* to workaround a bug in Android. This might apply to notification sounds and vibrations too.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#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 the POP3 protocol gives access to the inbox only. So, it is won't be possible to report spam for POP3 accounts.
Note that you should not delete spam messages, also not from the spam folder, because the email server uses the messages in the spam folder to "learn" what spam messages are.

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

Message classification will attempt to automatically group emails into classes, based on their contents, using [Bayesian statistics](https://en.wikipedia.org/wiki/Bayesian_statistics). In the context of FairEmail, a folder is a class. So, for example, the inbox, the spam folder, a 'marketing' folder, etc, etc.

Each folder has an option to enable automatic message classification. When this is turned on, new messages in other folders which the classifier thinks belong to that folder will be automatically moved.

The option *Use local spam filter* in the report spam dialog turns on message classification and auto classification for the spam folder. Please understand that this is not a replacement for the spam filter of the email server and can result in false positives. See also [this FAQ](#user-content-faq92).

A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the folder, FairEmail will start to move messages automatically into this folder. This will work best with similar messages.

Or, the other way around, after moving some messages out of the 'marketing' folder, FairEmail will stop moving similar messages automatically into this folder. This will work best with messages with similar content (email addresses, subject and message text).
Classification should be considered as a best guess - it might be a wrong guess, or the classifier might not be confident enough to make any guess. If the classifier is unsure, it will simply leave an email where it is.

Classification will be done for new messages in the inbox, spam folder and user folders only. You can clear local messages (long press a folder in the folder list of an account) and synchronize the messages again to classify existing messages.

Moving a message on the device will reclassify the message. Moving a message with another email client will not result in reclassification because IMAP does not support 'moved' notifications.
To prevent the email server from moving a message into the spam folder again and again, auto classification out of the spam folder will not be done.

The message classifier calculates the probability a message belongs in a folder (class). There are two options in miscellaneous settings that control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
* *Minimum class probability*: the minimum chance a message belongs in a folder (default 20 %)
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)
Both conditions must be satisfied before a message will be moved.
