In most cases, the quick setup wizard will be able to automatically identify the correct configuration.
4 years ago
If the quick setup wizard fails, you'll need to manually set up an account (to receive email) and an identity (to send email).
For this you'll need the IMAP and SMTP server addresses and port numbers, whether SSL/TLS or STARTTLS should be used
6 years ago
and your username (mostly, but not always, your email address) and your password.
Searching for *IMAP* and the name of the provider is mostly sufficient to find the right documentation.
4 years ago
In some cases, you'll need to enable external access to your account and/or to use a special (app) password,
for instance when two-factor authentication is enabled.

The design is based on many discussions and if you like you can discuss about it [in this forum](https://forum.xda-developers.com/android/apps-games/source-email-t3824168) too.
6 years ago
The goal of the design is to be minimalistic (no unnecessary menus, buttons, etc) and non distracting (no fancy colors, animations, etc).
6 years ago
All displayed things should be useful in one or another way and should be carefully positioned for easy usage.
5 years ago
Fonts, sizes, colors, etc should be material design whenever possible.

FairEmail will keep a list of addresses you receive messages from and send messages to
and will use this list for contact suggestions when no contacts permissions is granted to FairEmail.
This means you can use FairEmail without the Android contacts provider (address book).
Note that you can still pick contacts without granting contacts permissions to FairEmail,
only suggesting contacts won't work without contacts permissions.

**(2) Why is there a permanent notification shown?**
5 years ago
A low priority permanent status bar notification with the number of accounts being monitored and the number of operations pending (see the next question) is shown
5 years ago
to prevent Android from killing the service that takes care of continuous receiving email.
5 years ago
This was [already necessary](https://developer.android.com/reference/android/app/Service.html#startForeground(int,%20android.app.Notification)),
but with the introduction of [doze mode](https://developer.android.com/training/monitoring-device-state/doze-standby) in Android 6 Marshmallow this is more than ever necessary.
5 years ago
Doze mode will stop all apps when the screen is off for some time, unless the app did start a foreground service, which requires showing a status bar notification.
5 years ago
6 years ago
Most, if not all, other email apps don't show a notification
with the "side effect" that new messages are often not or late being reported and that messages are not or late being sent.
5 years ago
Android shows icons of high priority status bar notifications first and will hide the icon of FairEmail's notification if there is no space to show icons anymore.
In practice this means that the status bar notification doesn't take space in the status bar, unless there is space available.
5 years ago
The status bar notification can be disabled via the notification settings of FairEmail:
4 years ago
* Android 8 Oreo and later: tap the *Receive channel* button and disable the channel via the Android settings (this won't disable new message notifications)
5 years ago
* Android 7 Nougat and before: enabled *Use background service to synchronize messages*, but be sure to read the remark below the setting
5 years ago
5 years ago
You can switch to periodically synchronization of messages in the receive settings to remove the notification, but be aware that this might use more battery power.
See [here](#user-content-faq39) for more details about battery usage.
6 years ago
4 years ago
Android 8 Oreo might also show a status bar notification with the text *Apps are running in the background*.
5 years ago
Please see [here](https://www.reddit.com/r/Android/comments/7vw7l4/psa_turn_off_background_apps_notification/) about how you can disable this notification.
5 years ago
Some people suggested to use [Firebase Cloud Messaging](https://firebase.google.com/docs/cloud-messaging/) (FCM) instead of an Android service with a status bar notification,
but this would require email providers to send FCM messages or a central server where all messages are collected sending FCM messages.
The first is not going to happen and the last would have significant privacy implications.
4 years ago
If you came here by clicking on the notification, you should know that the next click will open the unified inbox.

**(3) What are operations and why are they pending?**
6 years ago
The low priority status bar notification shows the number of pending operations, which can be:
6 years ago
* *add*: add message to remote folder
* *move*: move message to another remote folder
* *copy*: copy message to another remote folder
5 years ago
* *fetch*: fetch changed (pushed) message
6 years ago
* *delete*: delete message from remote folder
* *seen*: mark message as read/unread in remote folder
* *answered*: mark message as answered in remote folder
* *flag*: add/remove star in remote folder
* *keyword*: add/remove IMAP flag in remote folder
* *label*: set/reset Gmail label in remote folder
6 years ago
* *headers*: download message headers
* *raw*: download raw message
6 years ago
* *body*: download message text
* *attachment*: download attachment
6 years ago
* *sync*: synchronize local and remote messages
* *subscribe*: subscribe to remote folder
* *purge*: delete all messages from remote folder
* *send*: send message
* *exists*: check if message exists
* *rule*: execute rule on body text
* *expunge*: permanently delete messages

**(4) How can I use an invalid security certificate / empty password / plain text connection?**
6 years ago
5 years ago
*... Untrusted ... not in certificate ...*
<br />
*... Invalid security certificate (Can't verify identity of server) ...*
4 years ago
This can be caused by using an incorrect host name, so first double check the host name in the advanced identity/account settings (tap Manual setup).
4 years ago
Please see the documentation of the email provider about the right host name.
You should try to fix this by contacting your provider or by getting a valid security certificate
6 years ago
because invalid security certificates are insecure and allow [man-in-the-middle attacks](https://en.wikipedia.org/wiki/Man-in-the-middle_attack).
If money is an obstacle, you can get free security certificates from [Lets Encrypt](https://letsencrypt.org).
4 years ago
The quick, but unsafe solution (not advised), is to enable *Insecure connections* in the advanced identity settings
4 years ago
(navigation menu, tap *Settings*, tap *Manual setup*, tap *Identities*, tap the identity, tap *Advanced*).
4 years ago
4 years ago
Alternatively, you can accept the fingerprint of invalid server certificates like this:
1. Make sure you are using a trusted internet connection (no public Wi-Fi networks, etc)
1. Go to the setup screen via the navigation menu (swipe from the left side inwards)
4 years ago
1. Tap Manual setup, tap Accounts/Identities and tap the faulty account and identity
4 years ago
1. Check/save the account and identity
1. Tick the checkbox below the error message and save again
4 years ago
This will "pin" the server certificate to prevent man-in-the-middle attacks.
5 years ago
5 years ago
Note that older Android versions might not recognize newer certification authorities like Lets Encrypt causing connections to be considered insecure,
see also [here](https://developer.android.com/training/articles/security-ssl).
4 years ago
<br />
5 years ago
*Trust anchor for certification path not found*
*... java.security.cert.CertPathValidatorException: Trust anchor for certification path not found ...*
means that the default Android trust manager was not able to verify the server certificate chain.
4 years ago
This could be due to the root certificate not being installed on your device
or because intermediate certificates are missing, for example because the email server didn't send them.
You can fix the first problem by downloading and installing the root certificate from the website of the provider of the certificate.
5 years ago
4 years ago
The second problem should be fixed by changing the server configuration or by importing the intermediate certificates on your device.
You can pin the certificate too, see above.
<br />
5 years ago
*Empty password*
6 years ago
Your username is likely easily guessed, so this is pretty insecure, unless the SMTP server is available via a restricted local network or a VPN only.
6 years ago
*Plain text connection*
6 years ago
Your username and password and all messages will be sent and received unencrypted, which is **very insecure**
5 years ago
because a [man-in-the-middle attack](https://en.wikipedia.org/wiki/Man-in-the-middle_attack) is very simple on an unencrypted connection.
If you still want to use an invalid security certificate, an empty password or a plain text connection
you'll need to enable insecure connections in the account and/or identity settings.
STARTTLS should be selected for plain text connections.
5 years ago
If you enable insecure connections, you should connect via private, trusted networks only and never via public networks, like offered in hotels, airports, etc.

4 years ago
In the display section of the settings you can enable or disable for example:
6 years ago
* *Unified inbox*: to disable the unified inbox and to list the folders selected for the unified inbox instead
4 years ago
* *Tabular style*: to show a linear list instead of cards
* *Group by date*: show date header above messages with the same date
* *Conversation threading*: to disable conversation threading and to show individual messages instead
4 years ago
* *Conversation action bar*: to disable the bottom navigation bar
* *Highlight color*: to select a color for the sender of unread messages
* *Show contact photos*: to hide contact photos
* *Show names and email addresses*: to show names or to show names and email addresses
* *Show subject italic*: to show the message subject as normal text
* *Show stars*: to hide stars (favorites)
4 years ago
* *Show message preview*: to show 1-4 lines of the message text
6 years ago
* *Show address details by default*: to expand the addresses section by default

Note that messages can be previewed only when the message text was downloaded.
Larger message texts are not downloaded by default on metered (generally mobile) networks.
4 years ago
You can change this in the connection settings.

**(6) How can I login to Gmail / G suite?**
6 years ago
4 years ago
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.
4 years ago
If you don't want to use or can't use an on-device Google account, for example on recent Huawei devices,
4 years ago
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.
4 years ago
To use a password you'll need to set up an account and identity via the manual setup instead of via the quick setup wizard.
4 years ago
4 years ago
**Important**: sometimes Google issues this alert:
*[ALERT] Please log in via your web browser: https://support.google.com/mail/accounts/answer/78754 (Failure)*
This Google security check is triggered more often with *less secure apps* enabled, less with an app password, and hardly when using an on-device account (OAuth).
4 years ago
Please see [this FAQ](#user-content-faq111) on why only on-device accounts can be used.
Note that an app specific password is required when two factor authentication is enabled.
4 years ago
After enabling two factor authentication there will be this error message:
*[ALERT] Application-specific password required: https://support.google.com/mail/accounts/answer/185833 (Failure)*
5 years ago
<br />
*App specific password*
See [here](https://support.google.com/accounts/answer/185833) about how to generate an app specific password.
<br />
*Enable "Less secure apps"*
**Important**: using this method is not recommended because it is less reliable.
**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).
See [here](https://support.google.com/accounts/answer/6010255) about how to enable "less secure apps"
6 years ago
or go [directy to the setting](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).
Be aware that you need to leave the "less secure apps" settings screen by using the back arrow to apply the setting.
5 years ago
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.
5 years ago
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).
5 years ago
<br />
6 years ago
5 years ago
*General*
5 years ago
5 years ago
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.

**(7) Why are sent messages not appearing (directly) in the sent folder?**
5 years ago
Sent messages are normally moved from the outbox to the sent folder as soon as your provider adds sent messages to the sent folder.
6 years ago
This requires a sent folder to be selected in the account settings and the sent folder to be set to synchronizing.
Some providers do not keep track of sent messages or the used SMTP server might not be related to the provider.
4 years ago
In these cases FairEmail, will automatically add sent messages to the sent folder on synchronizing the sent folder, which will happen after a message have been sent.
Note that this will result in extra internet traffic.
~~If this doesn't happen, your provider might not keep track of sent messages or you might be using an SMTP server not related to the provider.~~
~~In these cases you can enable the advanced identity setting *Store sent messages* to let FairEmail add sent messages to the sent folder right after sending a message.~~
~~Note that enabling this setting might result in duplicate messages if your provider adds sent messages to the sent folder too.~~
~~Also beware that enabling this setting will result in extra data usage, especially when when sending messages with large attachments.~~
~~If sent messages in the outbox are not found in the sent folder on a full synchronize, they will be moved from the outbox to the sent folder too.~~
~~A full synchronize happens when reconnecting to the server or when synchronizing periodically or manually.~~
~~You'll likely want to enable the advanced setting *Store sent messages* instead to move messages to the sent folder sooner.~~

**(9) What are identities / how do I add an alias?**
6 years ago
Identities represent email addresses you are sending *from* via an email (SMTP) server.
6 years ago
5 years ago
Some providers allow you to have multiple aliases.
You can configure these by setting the email address field of an additional identity to the alias address
and setting the user name field to your main email address.
5 years ago
Note that you can copy an identity by long pressing it.
5 years ago
Alternatively, you can enable *Allow editing sender address* in the advanced settings of an existing identity to edit the username when composing a new message,
if your provider allows this.
FairEmail will automatically update the passwords of related identities when you update the password of the associated account or a related identity.

~~Besides that any decent email provider supports [IMAP](https://en.wikipedia.org/wiki/Internet_Message_Access_Protocol) these days,~~
~~using [POP](https://en.wikipedia.org/wiki/Post_Office_Protocol) will result in unnecessary extra battery usage and delayed new message notifications.~~
~~Moreover, POP is unsuitable for two way synchronization and more often than not people read and write messages on different devices these days.~~
6 years ago
5 years ago
~~Basically, POP supports only downloading and deleting messages from the inbox.~~
~~So, common operations like setting message attributes (read, starred, answered, etc), adding (backing up) and moving messages is not possible.~~

**(12) How does encryption/decryption work?**
4 years ago
Communication with email servers is always encrypted, unless you explicitly turned this off.
This question is about optional end-to-end encryption with PGP or S/MIME.
The sender and recipient should first agree on this and exchange signed messages to transfer their public key to be able to send encrypted messages.
4 years ago
<br />
5 years ago
*General*
5 years ago
Please [see here](https://en.wikipedia.org/wiki/Public-key_cryptography) about how public/private key encryption works.
5 years ago
5 years ago
Encryption in short:
* **Outgoing** messages are encrypted with the **public key** of the recipient
* **Incoming** messages are decrypted with the **private key** of the recipient
Signing in short:
* **Outgoing** messages are signed with the **private key** of the sender
* **Incoming** messages are verified with the **public key** of the sender
5 years ago
5 years ago
To sign/encrypt a message, just select the appropriate method in the send dialog.
You can always open the send dialog using the three-dots overflow menu in case you selected *Don't show again* before.
5 years ago
To verify a signature or to decrypt a received message, open the message and just tap the gesture or padlock icon just below the message action bar.
6 years ago
5 years ago
The first time you send a signed/encrypted message you might be asked for a sign key.
FairEmail will automatically store the selected sign key in the used identity for the next time.
If you need to reset the sign key, just save the identity or long press the identity in the list of identities and select *Reset sign key*.
The selected sign key is visible in the list of identities.
5 years ago
If need to select a key on a case by case basis, you can create multiple identities for the same account with the same email address.
4 years ago
In the encryption settings you can select the default encryption method (PGP or S/MIME),
5 years ago
enable *Sign by default*, *Encrypt by default* and *Automatically decrypt messages*,
but be aware that automatic decryption is not possible if user interaction is required, like selecting a key or reading a security token.
6 years ago
5 years ago
The to be encrypted message text/attachments and the decrypted message text/attachments are stored locally only and will never be added to the remote server.
If you want to undo decryption, you can use the *resync* menu item in the three-dots menu of the message action bar.
6 years ago
4 years ago
<br />
5 years ago
*PGP*
5 years ago
You'll need to install and configure [OpenKeychain](https://f-droid.org/en/packages/org.sufficientlysecure.keychain/) first.
5 years ago
FairEmail was tested with OpenKeychain version 5.4. Later versions will most likely be compatible, but earlier versions might not be.
5 years ago
4 years ago
**Important**: the OpenKeychain app is known to (silently) crash when the calling app (FairEmail) is not authorized yet and is getting an existing public key.
5 years ago
You can workaround this by trying to send a signed/encrypted message to a sender with an unknown public key.
5 years ago
4 years ago
**Important**: if the OpenKeychain app cannot find a key (anymore), you might need to reset a previously selected key.
4 years ago
This can be done by long pressing an identity in the list of identities (Settings, tap Manual setup, tap Identities).
5 years ago
4 years ago
**Important**: to let apps like FairEmail reliably connect to the OpenKeychain service to encrypt/decrypt messages,
it might be necessary to disable battery optimizations for the OpenKeychain app.
4 years ago

FairEmail will send the [Autocrypt](https://autocrypt.org/) header for use by other email clients,
but only for signed and encrypted messages because too many email servers have problems with the often long Autocrypt header.
Note that the most secure way to start an encrypted email exchange is by sending signed messages first.
Received Autocrypt headers will be sent to the OpenKeychain app for storage on verifying a signature or decrypting a message.
5 years ago
4 years ago
Although this shouldn't be necessary for most email clients, you can attach your public key to a message
and if you use *.key* as extension, the mime type will correctly be *application/pgp-keys*.

All key handling is delegated to the OpenKey chain app for security reasons. This also means that FairEmail does not store PGP keys.

*S/MIME*
Encrypting a message requires the public key(s) of the recipient(s). Signing a message requires your private key.
Private keys are stored by Android and can be imported via the Android advanced security settings.
4 years ago
There is a shortcut (button) for this in the encryption settings.
5 years ago
Android will ask you to set a PIN, pattern, or password if you didn't before.

Note that certificates can contains multiple keys for multiple purposes, for example for authentication, encryption and signing.
Android only imports the first key, so to import all the keys, the certificate must first be split.
This is not very trivial and you are advised to ask the certificate supplier for support.

Public keys are stored by FairEmail and can be imported when verifying a signature for the first time or via the encryption settings (PEM or DER format).
5 years ago
FairEmail verifies both the signature and the complete certificate chain.
Common errors:
* *No certificate found matching targetContraints*: this likely means you are using an old version of FairEmail
* *unable to find valid certification path to requested target*: basically this means one or more intermediate or root certificates were not found
4 years ago
* *Private key does not match any encryption keys*: the selected key cannot be used to decrypt the message, probably because it is the incorrect key
4 years ago
* *No private key*: no certificate was selected or no certificate was available in the Android keystore

In case the certificate chain is incorrect, you can tap on the little info button to show the all certificates.
After the certificate details the issuer or "selfSign" is shown.
A certificate is self signed when the subject and the issuer are the same.
Certificates from a certificate authority (CA) are marked with "[keyCertSign](https://tools.ietf.org/html/rfc5280#section-4.2.1.3)".
Certificates found in the Android key store are marked with "Android".
A valid chain looks like this:
```
Your certificate > zero or more intermediate certificates > CA (root) certificate marked with "Android"
```
Note that a certificate chain will always be invalid when no anchor certificate can be found in the Android key store,
which is fundamental to S/MIME certificate validation.
Please see [here](https://support.google.com/pixelphone/answer/2844832?hl=en) how you can import certificates into the Android key store.

**(13) How does search on device/server work?**
6 years ago
5 years ago
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.
5 years ago
You can also search from any app by selecting *Search email* in the copy/paste popup menu.
6 years ago
4 years ago
Searching in the unified inbox will search in all folders of all accounts,
4 years ago
searching in the folder list will search in the associated account only
and searching in a folder will search in that folder only.
5 years ago
5 years ago
Messages will be searched for on the device first.
3 years ago
You can download more messages on the device via the three-dots overflow menu in the start screen.
5 years ago
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.
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.
6 years ago
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.
6 years ago
Searching on the server might be case sensitive or case insensitive and might be on partial text or whole words, depending on the provider.
6 years ago
5 years ago
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.
4 years ago
It is possible to use Gmail search operators by prefixing a search command with *raw:*.
4 years ago
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.
4 years ago
Please [see here](https://support.google.com/mail/answer/7190) for the possible search operators. For example:
4 years ago
``
raw:larger:10M
``
Searching through a large number of messages on the device is not very fast because of two limitations:
5 years ago
* [sqlite](https://www.sqlite.org/), the database engine of Android has a record size limit, preventing message texts from being stored in the database
* Android apps get only limited memory to work with, even if the device has plenty memory available
This means that searching for a message text requires that files containing the message texts need to be opened one by one
5 years ago
to check if the searched text is contained in the file, which is a relatively expensive process.
5 years ago
5 years ago
In the *miscellaneous settings* you can enable *Build search index* to significantly increase the speed of searching on the device,
5 years ago
but be aware that this will increase battery and storage space usage.
5 years ago
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.
5 years ago
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.
5 years ago
4 years ago
From version 1.1315 it is possible to use search expressions like this:
```
apple +banana -cherry ?nuts
```
This will result in searching like this:
```
("apple" AND "banana" AND NOT "cherry") OR "nuts"
```
Search expressions can be used for searching on the device via the search index and for searching on the email server,
but not for searching on the device without search index for performance reasons.
Searching on the device is a free feature, using the search index and searching on the server is a pro feature.
3 years ago
Note that you can download as many messages to your device as you like.
The easiest way is to use the menu item *Fetch more messages* in the three-dots menu of the start screen.

**(15) Why does the message text keep loading?**
6 years ago
The message header and message body are fetched separately from the server.
4 years ago
The message text of larger messages is not being pre-fetched on metered connections and will be fetched on demand on expanding a message.
4 years ago
The message text will keep loading if there is no connection to the account, see also the next question,
or if there other operations, like synchronizing messages, are being executed.
6 years ago
5 years ago
You can check the account and folder list for the account and folder state (see the legend for the meaning of the icons)
and the operation list accessible via the main navigation menu for pending operations (see [this FAQ](#user-content-faq3) for the meaning of the operations).
4 years ago
If FairEmail is holding off because of prior connectivity issues, please see [this FAQ](#user-content-faq123), you can force synchronization via the three dots menu.
In the receive settings you can set the maximum size for automatically downloading of messages on metered connections.

* The account or folder(s) are not set to synchronize
5 years ago
* The number of days to synchronize message for is set too low
6 years ago
* There is no usable internet connection
* The email server is temporarily not available
6 years ago
* Android stopped the synchronization service
6 years ago

So, check your account and folder settings and check if the accounts/folders are connected (see the legend in the navigation menu for the meaning of the icons).
If there are any error messages, please see [this FAQ](#user-content-faq22).

6 years ago
On some devices, where there are lots of applications competing for memory, Android may stop the synchronization service as a last resort.
5 years ago
5 years ago
Some Android versions stop apps and services too aggressively.

First of all, **FairEmail is basically free to use** and only some advanced features need to be purchased.
Zuerst, **FairEmail ist grundsätzlich kostenlos** und nur einige erweiterte Funktionen müssen gekauft werden.
Tout d'abord, **FairEmail est au fond gratuit** et seulement quelques fonctionnalités avancées doivent être achetés.
Please see the Play store description of the app or [see here](https://email.faircode.eu/#pro) for a complete list of pro features.

The right question is "*why are there so many taxes and fees?*":
6 years ago
* VAT: 25 % (depending on your country)
* Google fee: 30 %
* Income tax: 50 %
5 years ago
* <sub>Paypal fee: 5-10 % depending on the country/amount</sub>
6 years ago
So, what is left for the developer is just a fraction of what you pay.
Also note that most free apps will appear not to be sustainable in the end, whereas FairEmail is properly maintained and supported,
and that free apps may have a catch, like sending privacy sensitive information to the internet.

Some providers expect as username just *username* and others your full email address *username@example.com*.
4 years ago
When copying/pasting to enter a username or password, invisible characters might be copied, which could cause this problem as well.
4 years ago
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.

**Gmail errors**
The authorization of Gmail accounts setup with the quick wizard needs to be periodically refreshed
via the [Android account manager](https://developer.android.com/reference/android/accounts/AccountManager).
This requires contact/account permissions and internet connectivity.
4 years ago
In case of errors it is possible to authorize/restore a Gmail account again via the Gmail quick setup wizard.
5 years ago
The error *... Authentication failed ... Account not found ...* means that a previously authorized Gmail account was removed from the device.
The errors *... Authentication failed ... No token ...* means that the Android account manager failed to refresh the authorization of a Gmail account.
5 years ago
4 years ago
The error *... Authentication failed ... network error ...*
5 years ago
means that the Android account manager was not able to refresh the authorization of a Gmail account due to problems with the internet connection
4 years ago
The error *... Authentication failed ... Invalid credentials ...* could be caused by changing the account password
or by having revoked the required account/contacts permissions.
In case the account password was changed, you'll need to authenticate the Google account in the Android account settings again.
In case the permissions were revoked, you can start the Gmail quick setup wizard to grant the required permissions again (you don't need to setup the account again).
5 years ago
The eror *... ServiceDisabled ...* might be caused by enrolling in the [Advanced Protection Program](https://landing.google.com/advancedprotection/):
"*To read your email, you can (must) use Gmail - You wont be able to use your Google Account with some (all) apps & services that require access to sensitive data like your emails*",

**(23) Why do I get alert ... ?**
6 years ago
*General*
Alerts are warning messages sent by email servers.
*Too many simultaneous connections* or *Maximum number of connections exceeded*
This alert will be sent when there are too many folder connections for the same email account at the same time.
6 years ago
Possible causes are:
* There are multiple email clients connected to the same account
* The same email client is connected multiple times to the same account
* Previous connections were terminated abruptly for example by abruptly losing internet connectivity
6 years ago
5 years ago
First try to wait some time to see if the problem resolves itself, else:
* either switch to periodically checking for messages in the receive settings, which will result in opening folders one at a time
* or set some folders to poll instead of synchronize (long press folder in the folder list, edit properties)
6 years ago
4 years ago
An easy way to configure periodically checking for messages for all folders except the inbox
is to use *Apply to all ...* in the three-dots menu of the folder list and to tick the bottom two advanced checkboxes.
The maximum number of simultaneous folder connections for Gmail is 15,
6 years ago
so you can synchronize at most 15 folders simultaneously on *all* your devices at the same time.
5 years ago
For this reason Gmail *user* folders are set to poll by default instead of synchronize always.
When needed or desired, you can change this by long pressing a folder in the folder list and selecting *Edit properties*.
6 years ago
See [here](https://support.google.com/mail/answer/7126229) for details.
When using a Dovecot server,
you might want to change the setting [mail_max_userip_connections](https://doc.dovecot.org/settings/dovecot_core_settings/#mail-max-userip-connections).
4 years ago
Note that it will take the email server a while to discover broken connections, for example due to going out of range of a network,
which means that effectively only half of the folder connections are available. For Gmail this would be just 7 connections.

**(25) Why can't I select/open/save an image, attachment or a file?**
6 years ago
5 years ago
When a menu item to select/open/save a file is disabled (dimmed) or when you get the message *Storage access framework not available*,
the [storage access framework](https://developer.android.com/guide/topics/providers/document-provider), a standard Android component, is probably not present.
This might be because your custom ROM does not include it or because it was actively removed (debloated).
6 years ago
FairEmail does not request storage permissions, so this framework is required to select files and folders.
6 years ago
No app, except maybe file managers, targeting Android 4.4 KitKat or later should ask for storage permissions because it would allow access to *all* files.
6 years ago
5 years ago
The storage access framework is provided by the package *com.android.documentsui*,
which is visible as *Files* app on some Android versions (notable OxygenOS).
You can enable the storage access framework (again) with this adb command:
```
pm install -k --user 0 com.android.documentsui
```
Alternatively, you might be able to enable the *Files* app again using the Android app settings.

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

**(33) Why are edited sender addresses not working?**
Most providers accept validated addresses only when sending messages to prevent spam.
4 years ago
For example Google modifies the message headers like this for *unverified* addresses:
6 years ago
```
From: Somebody <somebody@example.org>
X-Google-Original-From: Somebody <somebody+extra@example.org>
```
4 years ago
This means that the edited sender address was automatically replaced by a verified address before sending the message.

**(34) How are identities matched?**
Identities are as expected matched by account.
For incoming messages the *to*, *cc*, *bcc*, *from* and *(X-)delivered/envelope/original-to* addresses will be checked (in this order)
and for outgoing messages (drafts, outbox and sent) only the *from* addresses will be checked.
Equal addresses have precedence over partially matching addresses, except for *delivered-to* addresses.
6 years ago
4 years ago
The matched address will be shown as *via* in the addresses section of received messages (between the message header and message text).
6 years ago
5 years ago
Note that identities needs to be enabled to be able to be matched
and that identities of other accounts will not be considered.
5 years ago
Matching will be done only once on receiving a message, so changing the configuration will not change existing messages.
You could clear local messages by long pressing a folder in the folder list and synchronize the messages again though.
5 years ago
It is possible to configure a [regex](https://en.wikipedia.org/wiki/Regular_expression) in the identity settings
4 years ago
to match **the username** of an email address (the part before the @ sign).
5 years ago
5 years ago
Note that the domain name (the parts after the @ sign) always needs to be equal to the domain name of the identity.
Since version 1.1640 it is possible to match the full email address with a regex, which can be useful for matching alias domain names.
5 years ago
4 years ago
If you like to match a catch-all email address, this regex is mostly okay:
```
.*
```
5 years ago
If you like to match the special purpose email addresses abc@example.com and xyx@example.com
and like to have a fallback email address main@example.com as well, you could do something like this:
* Identity: abc@example.com; regex: **(?i)abc**
* Identity: xyz@example.com; regex: **(?i)xyz**
* Identity: main@example.com; regex: **^(?i)((?!abc|xyz).)\*$**
Matched identities can be used to color code messages.

The identity color takes precedence over the folder and account color.
Setting identity colors is a pro feature.

**(35) Why should I be careful with viewing images, attachments, the original message, and opening links?**
6 years ago
4 years ago
Viewing remotely stored images (see also [this FAQ](#user-content-faq27)) and opening links might not only tell the sender that you have seen the message,
6 years ago
but will also leak your IP address.
4 years ago
See also this question: [Why email's link is more dangerous than web search's link?](https://security.stackexchange.com/questions/241139/why-emails-link-is-more-dangerous-than-web-searchs-link).
6 years ago
5 years ago
Opening attachments or viewing an original message might load remote content and execute scripts,
6 years ago
that might not only cause privacy sensitive information to leak, but can also be a security risk.
Note that your contacts could unknowingly send malicious messages if they got infected with malware.
5 years ago
FairEmail formats messages again causing messages to look different from the original, but also uncovering phishing links.
Note that reformatted messages are often better readable than original messages because the margins are removed, and font colors and sizes are standardized.
6 years ago
The Gmail app shows images by default by downloading the images through a Google proxy server.
Since the images are downloaded from the source server [in real-time](https://blog.filippo.io/how-the-new-gmail-image-proxy-works-and-what-this-means-for-you/),
this is even less secure because Google is involved too without providing much benefit.
You can show images and original messages by default for trusted senders on a case-by-case basis by checking *Do not ask this again for ...*.

**(39) How can I reduce the battery usage of FairEmail?**
6 years ago
Recent Android versions by default report *app usage* as a percentage in the Android battery settings screen.
5 years ago
**Confusingly, *app usage* is not the same as *battery usage* and is not even directly related to battery usage!**
5 years ago
The app usage (while in use) will be very high because FairEmail is using a foreground service which is considered as constant app usage by Android.
6 years ago
However, this doesn't mean that FairEmail is constantly using battery power.
5 years ago
The real battery usage can be seen by navigating to this screen:
*Android settings*, *Battery*, three-dots menu *Battery usage*, three-dots menu *Show full device usage*
6 years ago
As a rule of thumb the battery usage should be below or in any case not be much higher than *Mobile network standby*.
4 years ago
If this isn't the case, please turn on *Auto optimize* in the receive settings.
If this doesn't help, please [ask for support](https://contact.faircode.eu/?product=fairemailsupport).
6 years ago
5 years ago
It is inevitable that synchronizing messages will use battery power because it requires network access and accessing the messages database.
5 years ago
If you are comparing the battery usage of FairEmail with another email client, please make sure the other email client is setup similarly.
For example comparing always sync (push messages) and (infrequent) periodic checking for new messages is not a fair comparison.
5 years ago
Reconnecting to an email server will use extra battery power, so an unstable internet connection will result in extra battery usage.
4 years ago
Also, some email servers prematurely terminate idle connections, while [the standard](https://tools.ietf.org/html/rfc2177) says that an idle connection should be kept open for 29 minutes.
In these cases you might want to synchronize periodically, for example each hour, instead of continuously.
Note that polling frequently (more than every 30-60 minutes) will likely use more battery power than synchronizing always
4 years ago
because connecting to the server and comparing the local and remote messages are expensive operations.
5 years ago
4 years ago
[On some devices](https://dontkillmyapp.com/) it is necessary to *disable* battery optimizations (setup step 3) to keep connections to email servers open.
4 years ago
In fact, leaving battery optimizations enabled can result in extra battery usage for all devices, even though this sounds contradictory!
5 years ago
6 years ago
Most of the battery usage, not considering viewing messages, is due to synchronization (receiving and sending) of messages.
So, to reduce the battery usage, set the number of days to synchronize message for to a lower value,
especially if there are a lot of recent messages in a folder.
5 years ago
Long press a folder name in the folders list and select *Edit properties* to access this setting.
6 years ago
6 years ago
If you have at least once a day internet connectivity, it is sufficient to synchronize messages just for one day.
6 years ago
Note that you can set the number of days to *keep* messages for to a higher number than to *synchronize* messages for.
You could for example initially synchronize messages for a large number of days and after this has been completed
4 years ago
reduce the number of days to synchronize messages, but leave the number of days to keep messages.
After decreasing the number of days to keep messages, you might want to run the cleanup in the miscellaneous settings to remove old files.
6 years ago
In the receive settings you can enable to always synchronize starred messages,
6 years ago
which will allow you to keep older messages around while synchronizing messages for a limited number of days.
6 years ago
Disabling the folder option *Automatically download message texts and attachments*
will result in less network traffic and thus less battery usage.
You could disable this option for example for the sent folder and the archive.
6 years ago
Synchronizing messages at night is mostly not useful, so you can save on battery usage by not synchronizing at night.
5 years ago
In the settings you can select a schedule for message synchronization (this is a pro feature).
6 years ago

FairEmail will by default synchronize the folder list on each connection.
Since folders are mostly not created, renamed and deleted very often, you can save some network and battery usage by disabling this in the receive settings.
FairEmail will by default check if old messages were deleted from the server on each connection.
If you don't mind that old messages that were delete from the server are still visible in FairEmail, you can save some network and battery usage by disabling this in the receive settings.
3 years ago
Some providers don't follow the IMAP standard and [don't keep connections open](https://datatracker.ietf.org/doc/html/rfc3501#section-5.4) long enough, forcing FairEmail to reconnect often, causing extra battery usage.
5 years ago
You can inspect the *Log* via the main navigation menu to check if there are frequent reconnects (connection closed/reset, read/write error/timeout, etc).
5 years ago
You can workaround this by lowering the keep-alive interval in the advanced account settings to for example 9 or 15 minutes.
4 years ago
Note that battery optimizations need to be disabled in setup step 3 to reliably keep connections alive.
5 years ago
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.
5 years ago
You can inspect the *Log* via the main navigation menu to check if your provider is doing this.
5 years ago
If your provider is using [Dovecot](https://www.dovecot.org/) as IMAP server,
you could ask your provider to change the [imap_idle_notify_interval](https://wiki.dovecot.org/Timeouts) setting to a higher value or better yet, to disable this.
If your provider is not able or willing to change/disable this, you should consider to switch to periodically instead of continuous synchronization.
You can change this in the receive settings.
5 years ago
6 years ago
If you got the message *This provider does not support push messages* while configuring an account,
consider switching to a modern provider which supports push messages (IMAP IDLE) to reduce battery usage.
If your device has an [AMOLED](https://en.wikipedia.org/wiki/AMOLED) screen,
6 years ago
you can save battery usage while viewing messages by switching to the black theme.
If auto optimize in the receive settings is enabled,
an account will automatically be switched to periodically checking for new messages when the email server:
4 years ago
* Says '*Still here*' within 3 minutes
* The email server does not support push messages
* The keep-alive interval is lower than 12 minutes
In addition, the trash and spam folders will be automatically set to checking for new messages
after three successive [too many simultaneous connections](#user-content-faq23) errors.

**(40) How can I reduce the data usage of FairEmail?**
4 years ago
You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.
It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed.
If the connection is unstable, this can result in extra data usage.
4 years ago
In this case, it is a good idea to decrease the number of days to synchronize messages to a minimum (see the previous question)
4 years ago
or to switch to periodically synchronizing of messages (receive settings).
6 years ago
4 years ago
To reduce data usage, you could change these advanced receive settings:
* Check if old messages were removed from the server: disable
* Synchronize (shared) folder list: disable
5 years ago
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection.

**(41) How can I fix the error 'Handshake failed' ?**
6 years ago
6 years ago
There are several possible causes, so please read to the end of this answer.
5 years ago
The error '*Handshake failed ... WRONG_VERSION_NUMBER ...*' might mean that you are trying to connect to an IMAP or SMTP server
without an encrypted connection, typically using port 143 (IMAP) and port 25 (SMTP), or that a wrong protocol (SSL/TLS or STARTTLS) is being used.
6 years ago
Most providers provide encrypted connections using different ports, typically port 993 (IMAP) and port 465/587 (SMTP).
If your provider doesn't support encrypted connections, you should ask to make this possible.
If this isn't an option, you could enable *Allow insecure connections* both in the advanced settings AND the account/identity settings.
6 years ago
6 years ago
See also [this FAQ](#user-content-faq4).
5 years ago
The error '*Handshake failed ... SSLV3_ALERT_ILLEGAL_PARAMETER ...*' is either caused by a bug in the SSL protocol implementation
6 years ago
or by a too short DH key on the email server and can unfortunately not be fixed by FairEmail.
5 years ago
The error '*Handshake failed ... HANDSHAKE_FAILURE_ON_CLIENT_HELLO ...*' might be caused by the provider still using RC4,
5 years ago
which isn't supported since [Android 7](https://developer.android.com/about/versions/nougat/android-7.0-changes.html#tls-ssl) anymore.
4 years ago
The error '*Handshake failed ... UNSUPPORTED_PROTOCOL or TLSV1_ALERT_PROTOCOL_VERSION ...*'
might be caused by enabling hardening connections in the connection settings
5 years ago
or by Android not supporting older protocols anymore, like SSLv3.
5 years ago
5 years ago
Android 8 Oreo and later [do not support](https://developer.android.com/about/versions/oreo/android-8.0-changes#security-all) SSLv3 anymore.

**(43) Can you show the original ... ?**
6 years ago
Show original, shows the original message as the sender has sent it, including original fonts, colors, margins, etc.
FairEmail does and will not alter this in any way,
except for requesting [TEXT_AUTOSIZING](https://developer.android.com/reference/android/webkit/WebSettings.LayoutAlgorithm),
which will *attempt* to make small text more readable.

**(46) Why does the message list keep refreshing?**
If you see a 'spinner' at the top of the message list, the folder is still being synchronized with the remote server.
You can see the progress of the synchronization in the folder list. See the legend about what the icons and numbers mean.
4 years ago
The speed of your device and internet connection and the number of days to synchronize messages determine how long synchronization will take.
Note that you shouldn't set the number of days to synchronize messages to more than one day in most cases, see also [this FAQ](#user-content-faq39).

**(47) How do I solve the error 'No primary account or no drafts folder' ?**
6 years ago
You'll get the error message *No primary account or no drafts folder* when trying to compose a message
while there is no account set to be the primary account or when there is no drafts folder selected for the primary account.
This can happen for example when you start FairEmail to compose a message from another app.
FairEmail needs to know where to store the draft,
so you'll need to select one account to be the primary account and/or you'll need to select a drafts folder for the primary account.
6 years ago
This can also happen when you try to reply to a message or to forward a message from an account with no drafts folder
while there is no primary account or when the primary account does not have a drafts folder.

**(49) How do I fix 'An outdated app sent a file path instead of a file stream' ?**
6 years ago
You likely selected or sent an attachment or image with an outdated file manager
or an outdated app which assumes all apps still have storage permissions.
6 years ago
For security and privacy reasons modern apps like FairEmail have no full access to all files anymore.
6 years ago
This can result into the error message *An outdated app sent a file path instead of a file stream*
if a file name instead of a file stream is being shared with FairEmail because FairEmail cannot randomly open files.
6 years ago
6 years ago
You can fix this by switching to an up-to-date file manager or an app designed for recent Android versions.
Alternatively, you can grant FairEmail read access to the storage space on your device in the Android app settings.

**(52) Why does it take some time to reconnect to an account?**
There is no reliable way to know if an account connection was terminated gracefully or forcefully.
Trying to reconnect to an account while the account connection was terminated forcefully too often can result in problems
like [too many simultaneous connections](#user-content-faq23) or even the account being blocked.
To prevent such problems, FairEmail waits 90 seconds until trying to reconnect again.

**(53) Can you stick the message action bar to the top/bottom?**
6 years ago
5 years ago
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.
6 years ago
5 years ago
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.
5 years ago

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.

**(61) Why are some messages shown dimmed?**
5 years ago
Messages shown dimmed (grayed) are locally moved messages for which the move is not confirmed by the server 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.

**(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.
6 years ago
Images will by default be resized to a maximum width and height of about 1440 pixels and saved with a compression ratio of 90 %.

**(71) How do I use filter rules?**
4 years ago
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).
5 years ago
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*.
6 years ago
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.
5 years ago
The following rule conditions are available:
4 years ago
* Sender contains or sender is contact
5 years ago
* Recipient contains
* Subject contains
4 years ago
* Has attachments (optional of specific type)
5 years ago
* Header contains
4 years ago
* Absolute time (received) between (since version 1.1540)
* Relative time (received) between
5 years ago
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.
4 years ago
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.
4 years ago
If you want to match a domain name, you can use as a condition something like *@example.org*
4 years ago
Note that email addresses are formatted like this:
``
"Somebody" <somebody@example.org>
``
5 years ago
5 years ago
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).
5 years ago
Please see [here](https://developer.android.com/reference/java/util/regex/Pattern) for the documentation of Java regular expressions.
5 years ago
You can test a regex [here](https://regexr.com/).
4 years ago
Note that a regular expression supports an *or* operator, so if you want to match multiple senders, you can do this:
``
4 years ago
.*alice@example\.org.*|.*bob@example\.org.*|.*carol@example\.org.*
4 years ago
``
5 years ago
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).

An error in a rule condition can lead to a disaster, therefore irreversible actions are not supported.
5 years ago
Rules are applied directly after the message header has been fetched, but before the message text has been downloaded,
4 years ago
so it is not possible to apply conditions to the message text.
5 years ago
Note that large message texts are downloaded on demand on a metered connection to save on data usage.
5 years ago
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.
6 years ago
6 years ago
Since message headers are not downloaded and stored by default to save on battery and data usage and to save storage space
4 years ago
it is by default not possible to preview which messages would match a header rule condition.
You can enable downloading message headers in the connection settings and check headers conditions anyway (since version 1.1599).
5 years ago
4 years ago
Some common header conditions (regex):
* *.&ast;Auto-Submitted:.&ast;* [RFC3834](https://tools.ietf.org/html/rfc3834)

**(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.

<a name="faq74"></a>
**(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.
5 years ago
FairEmail shows all these messages in a non obtrusive way to indicate that these messages are in fact the same message.
6 years ago
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.

**(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?**
4 years ago
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.
5 years ago
4 years ago
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:
```
4 years ago
(adb shell) am start-foreground-service -a eu.faircode.email.POLL
```
For a specific account:
5 years ago
```
4 years ago
(adb shell) am start-foreground-service -a eu.faircode.email.POLL --es account Gmail
```
You can also automate turning receiving messages on and off by sending these commands to FairEmail:
```
4 years ago
(adb shell) am start-foreground-service -a eu.faircode.email.ENABLE
(adb shell) am start-foreground-service -a eu.faircode.email.DISABLE
```
To enable/disable a specific account:
```
4 years ago
(adb shell) am start-foreground-service -a eu.faircode.email.ENABLE --es account Gmail
(adb shell) am start-foreground-service -a eu.faircode.email.DISABLE --es account Gmail
```
5 years ago
Note that disabling an account will hide the account and all associated folders and messages.
From version 1.1600 an account will be disabled/enabled by setting the account to manual/automatic sync, so the folders and messages keep being accessible.
5 years ago
To set the poll interval:
```
(adb shell) adb shell am start-foreground-service -a eu.faircode.email.INTERVAL --ei minutes nnn
```
4 years ago
Where *nnn* is one of 0, 15, 30, 60, 120, 240, 480, 1440. A value of 0 means push messages.
6 years ago
You can automatically send commands with for example [Tasker](https://tasker.joaoapps.com/userguide/en/intents.html):
```
New task: Something recognizable
Action Category: Misc/Send Intent
Action: eu.faircode.email.ENABLE
Target: Service
```
To enable/disable an account with the name *Gmail*:
```
Extras: account:Gmail
```
Account names are case sensitive.
Scheduling is a pro feature.

**(79) How do I use synchronize on demand (manual)?**
6 years ago
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.
6 years ago
This will stop the background service which takes care of automatic synchronization and will remove the associated status bar notification.
6 years ago
5 years ago
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.
6 years ago
5 years ago
If you want to synchronize some or all folders of an account manually, just disable synchronization for the folders (but not of the account).
5 years ago
You'll likely want to disabled [browse on server](#user-content-faq24) too.

**~~(80) How do I fix the error 'Unable to load BODYSTRUCTURE' ?~~**
6 years ago
5 years ago
~~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.~~

**(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:
![External image](https://github.com/M66B/FairEmail/blob/master/images/baseline_my_location_black_48dp.png)
Automatic recognition of tracking images can be disabled in the privacy settings.

<a name="faq84"></a>
**(84) What are local contacts for?**
5 years ago
Local contact information is based on names and addresses found in incoming and outgoing messages.
6 years ago
The main use of the local contacts storage is to offer auto completion when no contacts permission has been granted to FairEmail.
6 years ago
Another use is to generate [shortcuts](#user-content-faq31) on recent Android versions to quickly send a message to frequently contacted people.
6 years ago
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.
6 years ago
The list of contacts is sorted on number of times contacted and the last time contacted.
5 years ago
By default only names and addresses to whom you send messages to will be recorded.
You can change this in the send settings.

<a name="faq85"></a>
**(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
6 years ago
FairEmail will try to select the best identity based on the *to* address of the message replied to / being forwarded.
<br />
<a name="faq86"></a>
**~~(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)~~
<br />
6 years ago
<a name="faq87"></a>
**(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/AT&T, AOL or Sky account?**
6 years ago
4 years ago
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).
3 years ago
To authorize a Yahoo/AT&T, AOL, or Sky account you need to use an app password instead of your normal account password.
For instructions about how to create an app password, please see here:

**(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.
<br />
<a name="faq90"></a>
**(90) Why are some texts linked while not being a link?**
4 years ago
FairEmail will automatically link not linked web links (http and https) and not linked email addresses (mailto) for your convenience.
6 years ago
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.
6 years ago
This is why texts with dots are sometimes incorrectly recognized as links, which is better than not recognizing some links.
6 years ago
4 years ago
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.
4 years ago
The regex to recognize links is already *very* complex and adding more protocols will make it only slower and possibly cause errors.
4 years ago
Note that original messages are shown exactly as they are, which means also that links are not automatically added.

**(92) Can you add spam filtering, verification of the DKIM signature and SPF authorization?**
6 years ago
6 years ago
Spam filtering, verification of the [DKIM](https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail) signature
6 years ago
and [SPF](https://en.wikipedia.org/wiki/Sender_Policy_Framework) authorization is a task of email servers, not of an email client.
5 years ago
Servers generally have more memory and computing power, so they are much better suited to this task than battery-powered devices.
5 years ago
Also, you'll want spam filtered for all your email clients, possibly including web email, not just one email client.
5 years ago
Moreover, email servers have access to information, like the IP address, etc of the connecting server, which an email client has no access to.
6 years ago
4 years ago
Spam filtering based on message headers might have been feasible,
4 years ago
but unfortunately this technique is [patented by Microsoft](https://patents.google.com/patent/US7543076).
4 years ago
4 years ago
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.
5 years ago
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.
5 years ago
This can be done automatically with [filter rules](#user-content-faq71) too.
4 years ago
Blocking the sender will create a filter rule to automatically move future messages of the same sender into the spam folder.
4 years ago
Note that the POP3 protocol gives access to the inbox only. So, it is won't be possible to report spam for POP3 accounts.
4 years ago
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.
5 years ago
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.
5 years ago
You can enable/disable [authentication verification](https://en.wikipedia.org/wiki/Email_authentication) in the display settings.
5 years ago
5 years ago
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.
5 years ago
This can be enabled in the receive settings. Be aware that this will slow down synchronization of messages significantly.
4 years ago
If the domain name of the sender and the domain name of the reply address differ,
4 years ago
the warning flag will be shown too because this is most often the case with phishing messages.
If desired, this can be disabled in the receive settings (from version 1.1506).
4 years ago
5 years ago
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)?**
6 years ago
5 years ago
FairEmail uses services and alarms, provides widgets and listens for the boot completed event to be started on device start,
5 years ago
so it is not possible to store the app on external storage media, like an sdcard.
6 years ago
See also [here](https://developer.android.com/guide/topics/data/install-location).
5 years ago
Messages, attachments, etc stored on external storage media, like an sdcard, can be accessed by other apps and is therefore not safe.
5 years ago
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.
5 years ago
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?**

<br />
6 years ago
<a name="faq95"></a>
**(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.
6 years ago
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.
6 years ago
Android Q will make it harder and maybe even impossible to directly access files,

**(97) What is 'cleanup' ?**
About each four hours FairEmail runs a cleanup job that:

**(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.

6 years ago
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.

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.

for a list of launchers which can show the number of unread messages.
4 years ago
Standard Android [does not support this](https://developer.android.com/training/notify-user/badges).
6 years ago
4 years ago
Note that Nova Launcher requires Tesla Unread, which is [not supported anymore](https://forum.xda-developers.com/android/general/bad-news-tesla-unread-devoloper-t3920415).
5 years ago
Note that the notification setting *Show launcher icon with number of new messages* needs to be enabled (default enabled).
5 years ago
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.
4 years ago
Depending on what you want, the notification settings *Let the number of new messages match the number of notifications* needs to be enabled (default disabled).
When enabled the badge count will be the same as the number of new message notifications.
When disabled the badge count will be the number of unread messages, independent if they are shown in a notification or are new.
5 years ago
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.
4 years ago
Some launchers display a dot or a '1' for [the monitoring notification](#user-content-faq2),
despite FairEmail explicitly requesting not to show a *badge* for this notification.

5 years ago
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).
6 years ago
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.

~~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.~~

**(112) Which email provider do you recommend?**
FairEmail is an email client only, so you need to bring your own email address.

Note that this is clearly mentioned in the app description.
There are plenty of email providers to choose from.

**(113) How does biometric authentication work?**
4 years ago
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 settings 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.
5 years ago
When biometric authentication is enabled new message notifications will not show any content and FairEmail won't be visible on the Android recents screen.
5 years ago
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.
4 years ago
For example, FairEmail has unlike most other email apps settings for the number of days to synchronize messages
and for the number of days to keep messages, mainly to save on battery usage.
4 years ago
Moreover, setting up an account/identity with the quick setup wizard 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.
5 years ago
Note that FairEmail will select the address only when long pressing an address, which makes it easy to delete an address.
5 years ago
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.

**(117) Can you help me restore my purchase?**
4 years ago
First of all, a purchase will be available on all devices logged into the same Google account,
*if* the app is installed via the same Google account too. You can select the account in the Play store app.
4 years ago
Google manages all purchases, so as a developer I have little control over purchases.
5 years ago
So, basically the only thing I can do, is give some advice:
5 years ago
5 years ago
* Make sure you have an active, working internet connection
5 years ago
* Make sure you are logged in with the right Google account and that there is nothing wrong with your Google account
4 years ago
* Make sure you installed FairEmail via the right Google account if you configured multiple Google accounts on your device
4 years ago
* Make sure the Play store app is up to date, please [see here](https://support.google.com/googleplay/answer/1050566?hl=en)
4 years ago
* Open the Play store app and wait at least a minute to give it time to synchronize with the Google servers
4 years ago
* Open FairEmail and navigate to the pro features screen to let FairEmail check the purchases; sometimes it help to tap the *buy* button
5 years ago
You can also try to clear the cache of the Play store app via the Android apps settings.
5 years ago
Restarting the device might be necessary to let the Play store recognize the purchase correctly.
5 years ago
Note that:
4 years ago
* 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)
3 years ago
* If you get *BILLING_UNAVAILABLE Google Play In-app Billing API version is less than 3*, the Play store app might not be logged into the account used to install the app
5 years ago
* 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
4 years ago
* An app like FairEmail cannot select which Google account to use
5 years ago
* It may take a while until the Play store app has synchronized a purchase to another device
4 years ago
* Play Store purchases cannot be used without the Play Store, which is also not allowed by Play Store rules
5 years ago
5 years ago
If you cannot solve the problem with the purchase, you will have to contact Google about it.

**(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.
5 years ago
Tapping on an individual new message notification will open the conversation the message it is part of.

5 years ago
<a name="faq121"></a>
**(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.
<br />

**~~(122) Why is the recipient name/email address show with a warning color?~~**
5 years ago
~~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?**
5 years ago
4 years ago
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,
4 years ago
FairEmail will retry one time after waiting 8 seconds while keeping the device awake (=use battery power).
4 years ago
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).
5 years ago
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.
5 years ago
*Force sync* in the three-dots menu of the unified inbox can be used to let FairEmail attempt to reconnect without waiting.
5 years ago
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.
5 years ago
You can pull down the outbox to retry manually.
5 years ago
5 years ago
Note that sending will not be retried in case of authentication problems and when the server rejected the message.

**(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.

*Send hard bounce (version 1.1477+)*
4 years ago
Send a [Delivery Status Notification](https://tools.ietf.org/html/rfc3464) (=hard bounce) via the reply/answer menu.
4 years ago
Hard bounces will mostly be processed automatically because they affect the reputation of the email provider.
The bounce address (=*Return-Path* header) is mostly very specific, so the email server can determine the sending account.
For some background, see for [this Wikipedia article](https://en.wikipedia.org/wiki/Bounce_message).

**(126) Can message previews be sent to my wearable?**
5 years ago
5 years ago
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.
5 years ago
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.
5 years ago
4 years ago
If you think this is good enough, you can enable the notification option *Only send notifications with a message preview to wearables*
4 years ago
and if this does not work, you can try to enable the notification option *Show notifications with a preview text only*.
4 years ago
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).
5 years ago
5 years ago
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.

**(129) Are ProtonMail, Tutanota supported?**
5 years ago
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.
5 years ago
Tutanota uses a proprietary email protocol
and [does not support IMAP](https://tutanota.com/faq/#imap),
so you cannot use FairEmail to access Tutanota.
<br />
<a name="faq130"></a>
**(130) What does message error ... mean?**
5 years ago
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?**
5 years ago
Notifications are silent by default on some MIUI versions.
5 years ago
Please see [here](http://en.miui.com/thread-3930694-1-1.html) how you can fix this.
5 years ago
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.
5 years ago
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.

*POP3*
5 years ago
4 years ago
In the account settings (Settings, tap Manual setup, tap Accounts, 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,
5 years ago
either via the three-dots menu in the action bar just above the message text
or by multiple selecting messages in the message list.
4 years ago
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.

**(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.

5 years ago
* Push messages are enabled for too many folders: see [this FAQ](#user-content-faq23) for more information and a workaround
4 years ago
* The account password was changed: changing it in FairEmail too should fix the problem

<a name="faq140"></a>
**(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.
5 years ago
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.
5 years ago
Other than that there is no way to reliably determine the correct character encoding automatically,
5 years ago
so this cannot be fixed by FairEmail. The right action is to complain to the sender.
5 years ago
<br />
<a name="faq141"></a>
**(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.
4 years ago
You can fix this problem by manually selecting the drafts folder in the account settings (Settings, tap Manual setup, tap Accounts, tap account, at the bottom).
5 years ago
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).

**(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.
5 years ago
If this is not an option, you can [create a rule](#user-content-faq71) to automatically move sent messages to the inbox

**~~(143) Can you add a trash folder for POP3 accounts?~~**
5 years ago
[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.
5 years ago
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.
5 years ago
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.

mostly because messages were incorrectly imported from another server and sometimes due to a bug in the email server.
5 years ago
4 years ago
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.
4 years ago
This can be changed in the advanced account settings: Settings, tap Manual setup, tap Accounts, tap account, tap Advanced.
5 years ago
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.
4 years ago
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.
5 years ago
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.
5 years ago
5 years ago
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.

**(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?**
5 years ago
An email client is meant to read and write messages, not to backup and restore messages.
4 years ago
Note that breaking or losing your device, means losing your messages!
Instead, the email provider/server is responsible for backups.

**(153) Why does permanently deleting Gmail message not work?**
5 years ago
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:
5 years ago
* 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
5 years ago
Note that archived messages can be deleted only by moving them to the trash folder first.
5 years ago
Some background: Gmail seems to have an additional message view for IMAP, which can be different from the main message view.
4 years ago
Another oddity is that a star (favorite message) set via the web interface cannot be removed with the IMAP command
```
STORE <message number> -FLAGS (\Flagged)
```
On the other hand, a star set via IMAP is being shown in the web interface and can be removed via IMAP.

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

**(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:
4 years ago
* [Open Camera](https://play.google.com/store/apps/details?id=net.sourceforge.opencamera) ([F-Droid](https://f-droid.org/en/packages/net.sourceforge.opencamera/))

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
4 years ago
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:

**(160) Can you add permanent deletion of messages without confirmation?**
4 years ago
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 :-(
4 years ago
Since version 1.1601 it is possible to disable confirmation of permanent deletion of individual messages.
Note that the POP3 protocol can download messages from the inbox only.
So, deleted messages cannot be uploaded to the inbox again.
This means that messages can only be permanently deleted when using a POP3 account.
4 years ago
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).
From version 1.1485 it is possible to temporarily enable debug mode in the miscellaneous settings to disable expunging messages.
Note that messages with a *\Deleted* flag will not be shown in FairEmail.

If I could, I would add a setting to select the primary and accent color right away,

**(162) Is IMAP NOTIFY supported?***
Yes, [IMAP NOTIFY](https://tools.ietf.org/html/rfc5465) has been supported since version 1.1413.
IMAP NOTIFY support means that notifications for added, changed or deleted messages of all *subscribed* folders will be requested
and if a notification is received for a subscribed folder, that the folder will be synchronized.
Synchronization for subscribed folders can therefore be disable, saving folder connections to the email server.
**Important**: push messages (=always sync) for the inbox and subscription management (receive settings) need to be enabled.
**Important**: most email servers do not support this! You can check the log via the navigation menu if an email server supports the NOTIFY capability.

**(163) What is message classification?**
4 years ago
*This is an experimental feature!*
4 years ago
Message classification will attempt to automatically group emails into classes, based on their contents,
4 years ago
using [Bayesian statistics](https://en.wikipedia.org/wiki/Bayesian_statistics).
4 years ago
In the context of FairEmail, a folder is a class. So, for example, the inbox, the spam folder, a 'marketing' folder, etc, etc.
You can enable message classification in the miscellaneous settings. This will enable 'learning' mode only.
The classifier will 'learn' from new messages in the inbox and spam folder by default.
The folder property *Classify new messages in this folder* will enable or disable 'learning' mode for a folder.
You can clear local messages (long press a folder in the folder list of an account) and synchronize the messages again to classify existing messages.
Each folder has an option *Automatically move classified messages to this folder* ('auto classification' for short).
When this is turned on, new messages in other folders which the classifier thinks belong to that folder will be automatically moved.
4 years ago
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).
4 years ago
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.
4 years ago
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).
4 years ago
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.
4 years ago
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.
4 years ago
The message classifier calculates the probability a message belongs in a folder (class).
There are two options in the miscellaneous settings which control if a message will be automatically moved into a folder,
4 years ago
provided that auto classification is enabled for the folder:
4 years ago
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 15 %)
4 years ago
* *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.
4 years ago
4 years ago
Considering the default option values:
4 years ago
* Apples 40 % and bananas 30 % would be disregarded because the difference of 25 % is below the minimum of 50 %
4 years ago
* Apples 10 % and bananas 5 % would be disregarded because the probability for apples is below the minimum of 15 %
4 years ago
* Apples 50 % and bananas 20 % would result in selecting apples
Classification is optimized to use as little resources as possible, but will inevitably use some extra battery power.
You can delete all classification data by turning classification in the miscellaneous settings three times off.
4 years ago
4 years ago
[Filter rules](#user-content-faq71) will be executed before classification.

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

**(164) Can you add customizable themes?**
Unfortunately, Android [does not support](https://stackoverflow.com/a/26511725/1794097) dynamic themes,
4 years ago
which means all themes need [to be predefined](https://github.com/M66B/FairEmail/blob/master/app/src/main/res/values/styles.xml).
4 years ago
4 years ago
Since for each theme there needs to be a light, dark and black variant,
it is not feasible to add for each color combination (literally millions) a predefined theme.
4 years ago
Moreover, a theme is more than just a few colors.
For example themes with a yellow accent color use a darker link color for enough contrast.
4 years ago
The theme colors are based on the color circle of [Johannes Itten](https://en.wikipedia.org/wiki/Johannes_Itten).

For notification (messaging) support you'll need to enable the following notification options:
* *Use Android 'messaging style' notification format*
* Notification actions: *Direct reply* and (mark as) *Read*

**(166) Can I snooze a message across multiple devices?**
4 years ago
First of all, there is no standard for snoozing messages, so all snooze implementations are custom solutions.
4 years ago
Some email providers, like Gmail, move snoozed messages to a special folder.
Unfortunately, third party apps have no access to this special folder.
Moving a message to another folder and back might fail and might not be possible if there is no internet connection.
This is problematic because a message can be snoozed only after moving the message.
4 years ago
To prevent these issues, snoozing is done locally on the device by hiding the message while it is snoozing.
4 years ago
Unfortunately, it is not possible to hide messages on the email server too.

**(168) What is a spam block list?**
A spam block list is basically a list of domain names which have been used to send spam or to spread malware.
3 years ago
A spam block list is checked by resolving the server name from the last *Received* header into an IP address
and looking up the IP address with a DNS request:
3 years ago
```
3 years ago
Received:
... from smtp.gmail.com ...
smtp.gmail.com ->
142.250.27.108
DNS lookup 108.27.250.142.zen.spamhaus.org ->
3 years ago
127.0.0.2: spam
NXDOMAIN: not spam
3 years ago
```
NXDOMAIN = no such domain
For more information, please see [this article](https://en.wikipedia.org/wiki/Domain_Name_System-based_blackhole_list).
3 years ago
You can check common block lists for example [here](https://mxtoolbox.com/blacklists.aspx).
FairEmail currently uses the following block lists:
* [Spamhaus](https://www.spamhaus.org/) &#8211; [Terms of Use](https://www.spamhaus.org/organization/dnsblusage/) &#8212; [Privacy policy](https://www.spamhaus.org/organization/privacy/)

From version 1.1627 it is possible to enable/disable individual blocklists in the receive settings of the app.
<br />
3 years ago
<a name="faq169"></a>
**(169) Why does the app not start automatically?**
FairEmail requests Android to start the app when the device starts up.
Obviously, this depends on Android as the app cannot start itself.
Some Android versions, such as EMUI, have settings to enable or disable auto starting apps.
So, if the app isn't started automatically, please check the Android settings.
For example for Huawei/EMUI, please [see here](https://dontkillmyapp.com/huawei) for a guide.
<br>
<a name="faq170"></a>
**(170) Why can't folders be created with POP3?**
The POP3 protocol has commands to download and delete messages from the inbox only.
There are no commands to access any other folder.
Creating a local folder only and storing messages on your device only is a bad idea
because losing or breaking your device would mean losing your messages.
Therefore this isn't supportable.
Please note that FairEmail doesn't store a copy of your messages in the cloud for privacy reasons.
If you want to store messages in folders, please use IMAP,
so that there is always a copy of the messages on the email server.
3 years ago

<a name="faq171"></a>
**(171) How can I delete a contact?**
A contact can be stored in the Android address book or in the local contact database.
When a contact is stored in the Android address book, you can use the Android contacts app to delete the contact.
When a contact is store in the local contact database, you can delete it like this:
* Go to the settings via the navigation menu (left side menu)
* Go to the send settings tab page
* Tap on the *Manage* button under *Suggest locally stored contacts*
* Locate the contact (you can use the magnifier glass in the top action bar)
* Long press the contact and select to delete it
