# FairEmail support
|
|
|
|
|
|
If you have a question, please check the frequently asked questions below first.
|
|
|
At the bottom you can find how to ask other questions, request features and report bugs.
|
|
|
|
|
|
|
|
|
## Authorizing accounts
|
|
|
|
|
|
For support on authorizing an account you should consult the documentation of your provider.
|
|
|
Searching for *IMAP* and the name of the provider is mostly sufficient to find the right documentation.
|
|
|
To setup an account (to receive email) and an identity (to send email)
|
|
|
you need the IMAP and SMTP server addresses and port numbers, whether STARTTLS should be used
|
|
|
and your username (mostly, but not always, your email address) and your password.
|
|
|
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.
|
|
|
|
|
|
For authorizing:
|
|
|
|
|
|
* Gmail / G suite: see [question 6](#user-content-faq6)
|
|
|
* Outlook / Hotmail: see [question 14](#user-content-faq14)
|
|
|
* Microsoft Exchange: see [question 8](#user-content-faq8)
|
|
|
* Yahoo!: see [question 88](#user-content-faq88)
|
|
|
|
|
|
## Known problems
|
|
|
|
|
|
* ~~A [bug in Android](https://issuetracker.google.com/issues/78495471) lets FairEmail occasionally crash on long pressing or swiping.~~
|
|
|
* ~~A [bug in Android 5.1 and 6](https://issuetracker.google.com/issues/37054851) causes apps to sometimes show a wrong time format. Toggling the Android setting *Use 24-hour format* might temporarily solve the issue.~~
|
|
|
* ~~A [bug in Google Drive](https://issuetracker.google.com/issues/126362828) causes files exported to Google Drive to be empty.~~
|
|
|
* "*... Couldn't read row ...*" causes sometimes a crash. This could be caused by a bug in the [Room Persistence Library](https://developer.android.com/topic/libraries/architecture/room) but more likely indicates a corrupt database.
|
|
|
* A [bug in Android](https://issuetracker.google.com/issues/119872129) "*... Bad notification posted ...*" lets FairEmail crash on some devices after updating FairEmail and tapping on a notification.
|
|
|
* A [bug in Android](https://issuetracker.google.com/issues/62427912) "*... ActivityRecord not found for ...*" sometimes causes a crash after updating FairEmail. Reinstalling ([source](https://stackoverflow.com/questions/46309428/android-activitythread-reportsizeconfigurations-causes-app-to-freeze-with-black)) migth fix the problem.
|
|
|
* Encryption with [YubiKey](https://www.yubico.com/) results into an infinite loop. FairEmail follows the latest version of the [OpenKeychain API](https://github.com/open-keychain/openpgp-api), so this is likely being caused by an external bug.
|
|
|
* A bug in the Nova Launcher lets FairEmail crash with a *java.lang.StackOverflowError* when the Nova Launcher has access to the accessibility service.
|
|
|
|
|
|
## Planned features
|
|
|
|
|
|
* ~~Synchronize on demand (manual)~~
|
|
|
* ~~Semi-automatic encryption~~
|
|
|
* ~~Copy message~~
|
|
|
* ~~Colored stars~~
|
|
|
* ~~Notification settings per folder~~
|
|
|
* ~~Select local images for signatures~~ (this will not be added because it requires image file management and because images are not shown by default in most email clients anyway)
|
|
|
* ~~Show messages matched by a rule~~
|
|
|
* [ManageSieve](https://tools.ietf.org/html/rfc5804)
|
|
|
* ~~Search for messages with/without attachments~~ (this cannot be added because IMAP doesn't support searching for attachments)
|
|
|
* Search for a folder
|
|
|
|
|
|
Anything on this list is in random order and *might* be added in the near future.
|
|
|
|
|
|
|
|
|
## Frequently requested features
|
|
|
|
|
|
* *Design*: 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. See below for the design goals.
|
|
|
* *Widget to read messages*: widgets can have limited user interaction only, so a widget to read conversations would not be very convenient. Moreover, it would be not very useful to duplicate functions which are already available in the app.
|
|
|
* *ActiveSync*: using the Exchange ActiveSync protocol requires [a license](https://en.wikipedia.org/wiki/Exchange_ActiveSync#Licensing), so this cannot be added.
|
|
|
|
|
|
The goal of the design is to be minimalistic (no unnecessary menus, buttons, etc) and non distracting (no fancy colors, animations, etc).
|
|
|
All displayed things should be useful in one or another way and should be carefully positioned for easy usage.
|
|
|
Fonts, sizes, colors, etc should be material design wherever possible.
|
|
|
|
|
|
Since FairEmail is meant to be privacy friendly, the following will not be added:
|
|
|
|
|
|
* Open links without confirmation
|
|
|
* Show images and original messages without confirmation, see also [this FAQ](#user-content-faq35)
|
|
|
* Direct file/folder access: for security/privacy reasons (other) apps should use the [Storage Access Framework](https://developer.android.com/guide/topics/providers/document-provider), see also [this FAQ](#user-content-faq49)
|
|
|
|
|
|
Confirmation is just one tap, which is just a small price for better privacy.
|
|
|
Note that your contacts could unknowingly send malicious messages if they got infected with malware.
|
|
|
|
|
|
Stripped and reformatted messages are often better readable than original messages because the margins are removed, and font colors and sizes are standardized.
|
|
|
|
|
|
FairEmail does not allow other apps access to your messages and attachments without your approval.
|
|
|
|
|
|
FairEmail follows all the best practices for an email client as decribed in [this EFF article](https://www.eff.org/deeplinks/2019/01/stop-tracking-my-emails).

[I have another question.](#support)
|
|
|
|
|
|
<a name="faq1"></a>
|
|
|
**(1) Which permissions are needed and why?**
|
|
|
|
|
|
The following Android permissions are needed:
|
|
|
|
|
|
* *have full network access* (INTERNET): to send and receive email
|
|
|
* *view network connections* (ACCESS_NETWORK_STATE): to monitor internet connectivity changes
|
|
|
* *run at startup* (RECEIVE_BOOT_COMPLETED): to start monitoring on device start
|
|
|
* *foreground service* (FOREGROUND_SERVICE): to run a foreground service on Android 9 Pie and later, see also the next question
|
|
|
* *prevent device from sleeping* (WAKE_LOCK): to keep the device awake while synchronizing messages
|
|
|
* *in-app billing* (BILLING): to allow in-app purchases
|
|
|
* Optional: *read your contacts* (READ_CONTACTS): to autocomplete addresses and to show photos
|
|
|
* Optional: *read the contents of your SD card* (READ_EXTERNAL_STORAGE): to accept files from other, outdated apps, see also [this FAQ](#user-content-faq49)
|
|
|
|
|
|
The following permissions are needed to show the count of unread messages as a badge (see also [this FAQ](#user-content-faq106)):
|
|
|
|
|
|
* *com.sec.android.provider.badge.permission.READ*
|
|
|
* *com.sec.android.provider.badge.permission.WRITE*
|
|
|
* *com.htc.launcher.permission.READ_SETTINGS*
|

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?**
|
|
|
|
|
|
A permanent status bar notification with the number of accounts being synchronized and the number of operations pending (see next question) is shown
|
|
|
to prevent Android from killing the service that takes care of receiving and sending email.
|
|
|
|
|
|
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.
|
|
|
|
|
|
Background: this is necessary because of the introduction of [doze mode](https://developer.android.com/training/monitoring-device-state/doze-standby) in Android 6 Marshmallow.
|
|
|
|
|
|
If you came here by clicking on the notification, you should known that the next click will open the unified inbox.
|
|
|
|
|

|
|
|
|
|
<a name="faq3"></a>
|
|
|
**(3) What are operations and why are they pending?**
|
|
|
|
|
|
The low priority status bar notification shows the number of pending operations, which can be:
|
|
|
|
|
|
* *add*: add message to remote folder
|
|
|
* *move*: move message to another remote folder
|
|
|
* *copy*: copy message to another remote folder
|
|
|
* *delete*: delete message from remote folder
|
|
|
* *send*: send message
|
|
|
* *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
|
|
|
* *headers*: download message headers
|
|
|
* *raw*: download raw message
|
|
|
* *body*: download message text
|
|
|
* *attachment*: download attachment
|
|
|
* *sync*: synchronize local and remote messages
|
|
|
* *subscribe*: subscribe to remote folder
|
|
|
|
|
|
Operations are processed only when there is a connection to the email server or when manually synchronizing.
|
|

|
**(4) How can I use an invalid security certificate / IMAP STARTTLS / an empty password?**
|
|
|
|
|
|
Invalid security certificate (*Can't verify identity of server*): you should try to fix this by contacting your provider or by getting a valid security certificate
|
|
|
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 [Let’s Encrypt](https://letsencrypt.org).
|
|
|
|
|
|
Note that older Android versions might not recognize newer certification authorities like Let’s Encrypt causing connections to be considered insecure,
|
|
|
see also [here](https://developer.android.com/training/articles/security-ssl).

IMAP STARTTLS: the EFF [writes](https://www.eff.org/nl/deeplinks/2018/06/announcing-starttls-everywhere-securing-hop-hop-email-delivery):
|
|
|
"*Additionally, even if you configure STARTTLS perfectly and use a valid certificate, there’s still no guarantee your communication will be encrypted.*"
|
|
|
|
|
|
Empty password: your username is likely easily guessed, so this is very insecure.
|
|
|
|
|
|
If you still want to use an invalid security certificate, IMAP STARTTLS or an empty password,
|
|
|
you'll need to enable insecure connections in the account and/or identity settings.
|
|
|
|
|
|
Connections without encryption (either SSL or STARTTLS) are not supported because this is very insecure.

**(5) How can I customize the message view?**
|
|
|
|
|
|
In the three dot overflow menu you can enable or disable or select:
|
|
|
|
|
|
* *text size*: for three different font sizes
|
|
|
* *compact view*: for more condensed message items and a smaller message text font
|
|
|
|
|
|
In the display section of the settings you can enable or disable:
|
|
|
|
|
|
* *Unified inbox*: to disable the unified inbox and to list the folders selected for the unified inbox instead
|
|
|
* *Group by date*: show date header above messages with the same date
|
|
|
* *Conversation threading*: to disable conversation threading and to show individual messages instead
|
|
|
* *Show contact photos*: to hide contact photos
|
|
|
* *Show identicons*: to show generated contact avatars
|
|
|
* *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)
|
|
|
* *Show message preview*: to show two lines of the message text
|
|
|
* *Show address details by default*: to expand the addresses section by default
|
|
|
* *Use monospaced font for message text*: to use a fixed width typeface for message texts
|
|
|
* *Automatically show original message for known contacts*: to automatically show original messages for contacts on your device, please read [this FAQ](#user-content-faq35)
|
|
|
* *Automatically show images for known contacts*: to automatically show images for contacts on your device, please read [this FAQ](#user-content-faq35)
|
|
|
* *Conversation action bar*: to disable the bottom navigation bar
|
|
|
|
|
|
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.
|
|
|
You can change this in the settings.
|
|
|
|
|
|
If the list of addresses is long, you can collapse the addresses section with the *less* icon at the top of the addresses section.
|
|
|
|
|
|
Some people ask:
|
|
|
|
|
|
* to show the subject bold, but bold is already being used to highlight unread messages
|
|
|
* to show the address or subject larger/smaller, but this would interfere with the text size option
|
|
|
* to move the star to the left, but it is much easier to operate the star on the right side
|
|
|
|
|
|
Unfortunately, it is impossible to make everybody happy and adding lots of settings would not only be confusing, but also never be sufficient.

**(6) How can I login to Gmail / G suite?**
|
|
|
|
|
|
To use a Gmail/G suite account,
|
|
|
you can either enable access for "less secure apps" and use your account password
|
|
|
or enable two factor authentication and use an app specific password.
|
|
|
|
|
|
Note that an app specific password is required when two factor authentication is enabled.
|
|
|
|
|
|
**Enable "Less secure apps"**
|
|
|
|
|
|
See [here](https://support.google.com/accounts/answer/6010255) about how to enable "less secure apps"
|
|
|
or go [directy to the setting](https://www.google.com/settings/security/lesssecureapps).
|
|
|
|
|
|
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.
|
|
|
|
|
|
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).
|
|
|
|
|
|
**App specific password**
|
|
|
|
|
|
See [here](https://support.google.com/accounts/answer/185833) about how to generate an app specific password.
|
|
|
|
|
|
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 to be unsafe.
|
|
|
This can be prevented by using an app specific password.
|
|
|
|
|
|
See [here](https://support.google.com/mail/accounts/answer/78754) for troubleshooting.

|
|
|
**(7) Why are sent messages not appearing sent folder?**
|
|
|
|
|
|
Sent messages are normally added to the sent folder as soon as your provider adds the messages to the sent folder.
|
|
|
This requires a sent folder to be selected in the account settings and the sent folder to be set to synchronizing.
|
|
|
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 workaround this.
|
|
|
|
|
|
Note that FairEmail will automatically add sent messages to the sent folder when performing a full synchronize,
|
|
|
which happens when reconnecting or if you synchronize manually.

**(8) Can I use a Microsoft Exchange account?**
|
|
|
|
|
|
You can use a Microsoft Exchange account if it is accessible via IMAP.
|
|
|
See [here](https://support.office.com/en-us/article/what-is-a-microsoft-exchange-account-47f000aa-c2bf-48ac-9bc2-83e5c6036793) for more information.

|
|
|
**(9) What are identities / how do I add an alias?**
|
|
|
|
|
|
Identities represent email addresses you are sending *from*.
|
|
|
|
|
|
Some providers allow you to have multiple email aliases.
|
|
|
You can configure these by setting the email address field to the alias address and setting the user name field to your main email address.

|
|
|
**~~(10) What does 'UIDPLUS not supported' mean?~~**
|
|
|
|
|
|
~~The error message *UIDPLUS not supported* means that your email provider does not provide the IMAP [UIDPLUS extension](https://tools.ietf.org/html/rfc4315).
|
|
|
This IMAP extension is required to implement two way synchronization, which is not an optional feature.
|
|
|
So, unless your provider can enable this extension, you cannot use FairEmail for this provider.~~

<a name="faq11"></a>
|
|
|
**(11) Why is POP not supported?**
|
|
|
|
|
|
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.
|
|
|
|
|
|
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.
|
|
|
|
|
|
See also [what Google writes about it](https://support.google.com/mail/answer/7104828).
|
|
|
|
|
|
For example [Gmail can import messages](https://support.google.com/mail/answer/21289) from another POP account,
|
|
|
which can be used as a workaround for when your provider doesn't support IMAP.
|
|
|
|
|
|
tl;dr; consider to switch to IMAP.

|
|
|
**(12) How does encryption/decryption work?**
|
|
|
|
|
|
First of all you need to install and configure [OpenKeychain](https://f-droid.org/en/packages/org.sufficientlysecure.keychain/).
|
|
|
To encrypt and send a message just check the menu *Encrypt* and the message will be encrypted on sending.
|
|
|
Similarly, to decrypt a received message, just select the menu *Decrypt* in the expanded message view.
|
|
|
|
|
|
You can enable *Encrypt by default* in the identity settings, which replaces *Send* by *Encrypt and send*.
|
|
|
|
|
|
FairEmail will send the [Autocrypt](https://autocrypt.org/) headers for other email clients.
|
|
|
Received messages are not decrypted automatically because of security reasons and because often manual interaction is required.
|
|
|
|
|
|
The decrypted message text and decrypted attachments are stored. If you want to undo this, you can use the *resync* message 'more' menu.
|
|
|
|
|
|
Inline PGP in received messages is supported, but inline PGP in outgoing messages is not supported,
|
|
|
see [here](https://josefsson.org/inline-openpgp-considered-harmful.html) about why not.
|
|
|
|
|
|
S/MIME is not supported because it is not used much and because key management is complex.
|
|
|
There are also [security concerns](https://security.stackexchange.com/a/83752).
|
|
|
|
|
|
Note that signed only or encrypted only messages are not supported, see here about why not:
|
|
|
|
|
|
* [OpenPGP Considerations Part I](https://k9mail.github.io/2016/11/24/OpenPGP-Considerations-Part-I.html)
|
|
|
* [OpenPGP Considerations Part II](https://k9mail.github.io/2017/01/30/OpenPGP-Considerations-Part-II.html)
|
|
|
* [OpenPGP Considerations Part III Autocrypt](https://k9mail.github.io/2018/02/26/OpenPGP-Considerations-Part-III-Autocrypt.html)
|
|
|
|
|
|
If you want, you can verify a signature by opening the *signature.asc* attachment.
|
|
|
|
|
|
Encryption/decryption is a pro feature.

|
**(13) How does search on device/server work?**
|
|
|
|
|
|
You can start searching for messages on sender, recipient, subject, keyword or message text by using the magnify glass in the action bar of a folder.
|
|
|
You can also search from any app by select *Search email* in the copy/paste popup menu.
|
|
|
|
|
|
Messages will be searched on the device first (all accounts, all folders).
|
|
|
There will be an action button with a search again icon at the bottom to search on the server.
|
|
|
When the search was started in a specific folder,
|
|
|
the same folder will be searched in on the server,
|
|
|
else you can select which folder to search in on the server.
|
|
|
|
|
|
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.
|
|
|
|
|
|
Searching local messages is case insensitive and on partial text.
|
|
|
The message text of local messages will not be searched if the message text was not downloaded yet.
|
|
|
Searching on the server might be case sensitive or case insensitive and might be on partial text or whole words, depending on the provider.
|
|
|
|
|
|
Searching messages is a pro feature.

|
**(14) How can I setup Outlook / Hotmail with 2FA?**
|
|
|
|
|
|
To use Outlook or Hotmail with two factor authentication enabled, you need to create an app password.
|
|
|
See [here](https://support.microsoft.com/en-us/help/12409/microsoft-account-app-passwords-two-step-verification) for the details.

|
|
<a name="faq15"></a>
|
|
|
**(15) Why does the message text keep loading?**
|
|
|
|
|
|
The message header and message body are fetched separately from the server.
|
|
|
The message text of larger messages is not being pre-fetched on metered connections and need to be fetched on opening the message.
|
|
|
The message text will keep loading if there is no connection to the account, see also the next question.
|
|
|
|
|
|
In the advanced settings you can set the maximum size for automatically downloading of messages on metered connections.
|
|
|
|
|
|
Mobile connections are almost always metered and some (paid) Wi-Fi hotspots are too.

|
|
|
**(16) Why are messages not being synchronized?**
|
|
|
|
|
|
Possible causes of messages not being synchronized (sent or received) are:
|
|
|
|
|
|
* The account or folder(s) are not set to synchronize
|
|
|
* The number of days to synchronize is set to low
|
|
|
* There is no usable internet connection
|
|
|
* The email server is temporarily not available
|
|
|
* Android stopped the synchronization service
|
|
|
|
|
|
So, check your account and folder settings and check if the accounts/folders are connected (see the legend menu for the meaning of the icons).
|
|
|
|
|
|
On some devices, where there are lots of applications competing for memory, Android may stop the synchronization service as a last resort.
|
|
|
Some Android versions,
|
|
|
in particular of Huawei (see [here](https://www.forbes.com/sites/bensin/2016/07/04/push-notifications-not-coming-through-to-your-huawei-phone-heres-how-to-fix-it/) for a fix)
|
|
|
or Xiaomi (see [here](https://www.forbes.com/sites/bensin/2016/11/17/how-to-fix-push-notifications-on-xiaomis-miui-8-for-real/) for a fix)
|
|
|
stop apps and services too aggressively.

**(19) Why are the pro features so expensive?**
|
|
|
|
|
|
The right question is "*why are there so many taxes and fees?*":
|
|
|
|
|
|
* VAT: 25 % (depending on your country)
|
|
|
* Google fee: 30 %
|
|
|
* Income tax: 50 %
|
|
|
|
|
|
So, what is left for the developer is just a fraction of what you pay.
|
|
|
|
|
|
Note that only some convenience and advanced features need to be purchased which means that FairEmail is basically free to use.
|
|
|
|
|
|
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.

**(20) Can I get a refund?**
|
|
|
|
|
|
If a purchased pro feature doesn't work as intended
|
|
|
and this isn't caused by a problem in the free features
|
|
|
and I cannot fix the problem in a timely manner, you can get a refund.
|
|
|
In all other cases there is no refund possible.
|
|
|
In no circumstances there is a refund possible for any problem related to the free features,
|
|
|
since there wasn't paid anything for them and because they can be evaluated without any limitation.
|
|
|
I take my responsibility as seller to deliver what has been promised
|
|
|
and I expect that you take responsibility for informing yourself of what you are buying.

**(21) How do I enable the notification light?**
|
|
|
|
|
|
Before Android 8 Oreo: there is an advanced option in the setup for this.
|
|
|
|
|
|
Android 8 Oreo and later: see [here](https://developer.android.com/training/notify-user/channels) about how to configure notification channels.
|
|
|
You can use the button *Manage notifications* in the setup to directly go to the Android notification settings.
|

**(22) What do 'Couldn't connect to host', 'Connection refused', 'Network unreachable', 'Software caused connection abort', 'Connection reset by peer', 'Read timed out' and 'Broken pipe' mean?**
|
|
|
|
|
|
The messages *... Couldn't connect to host ...*, *... Connection refused ...* or *... Network unreachable ...*
|
|
|
mean that FairEmail was not able to connect to the email server.
|
|
|
|
|
|
The message *... Software caused connection abort ...*
|
|
|
means that the email server or something between FairEmail and the email server actively terminated an existing connection.
|
|
|
This can for example happen when connectivity was abruptly lost. A typical example is turning on flight mode.
|
|
|
|
|
|
The message *... Connection reset by peer ...* or *... Broken pipe ...* means that the email server actively terminated an existing connection.
|
|
|
|
|
|
The message *... Read timed out ...* means that the email server is not responding anymore or that the internet connction is bad.
|
|
|
|
|
|
See [here](https://linux.die.net/man/3/connect) for what error codes like EHOSTUNREACH and ETIMEDOUT mean.
|
|
|
|
|
|
Possible causes are:
|
|
|
|
|
|
* A firewall or router is blocking connections to the server
|
|
|
* The host name or port number is invalid
|
|
|
* The are problems with the internet connection
|
|
|
* The email server is refusing to accept connections
|
|
|
* The email server is refusing to accept a message, for example because it is too large or contains unacceptable links
|
|
|
* There are too many connections to the server, see also the next question
|
|
|
|
|
|
If you are using a VPN, the VPN provider might block the connection because it is too aggressively trying to prevent spam.
|
|
|
|
|
|
FairEmail will automatically try to connect again after a delay.
|
|
|
This delay will be doubled after each failed attempt to prevent draining the battery and to prevent from being locked out permanently.
|
|
|
|
|
|

|
|
<a name="faq23"></a>
|
|
|
**(23) Why do I get 'Too many simultaneous connections' ?**
|
|
|
|
|
|
The message *Too many simultaneous connections* is sent by the email server
|
|
|
when there are too many folder connections for the same email account at the same time.
|
|
|
|
|
|
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
|
|
|
* The previous connection was terminated abruptly for example by abruptly losing internet connectivity, for example when turning on flight mode
|
|
|
|
|
|
If only FairEmail is connecting to the email server, first try to wait half an hour to see if the problem resolves itself,
|
|
|
else enable the folder setting '*Poll instead of synchronize*' for some folders.
|
|
|
The poll interval can be configured in the account settings.
|
|
|
|
|
|
The maximum number of simultaneous folder connections for Gmail is 15,
|
|
|
so you can synchronize at most 15 folders simultaneously on *all* your devices at the same time.
|
|
|

**(24) What is browse messages on the server?**
|
|
|
|
|
|
Browse messages on the server will fetch messages from the email server in real time

|
|
when you reach the end of the list of synchronized messages, even when the folder is set to not synchronize.
|
|
|
You can disable this feature in the advanced account settings.

If a menu item to select/open/save a file is disabled (dimmed) or not available,
|
|
|
the [storage access framework](https://developer.android.com/guide/topics/providers/document-provider),
|
|
|
a standard Android component, is probably not present,
|
|
|
for example because your custom ROM does not include it or because it was removed.
|
|
|
FairEmail does not request storage permissions, so this framework is required to select files and folders.
|
|
|
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.

**(27) How can I differentiate external and embedded images?**
|
|
|
|
|
|
External image:
|
|
|
|
|
|
|
|
|
|
|
|
Embedded image:
|
|
|
|
|
|
|
|
|
|
|
|
Broken image:
|
|
|
|
|
|
|
|
|
|
|
|
Note that downloading external images from a remote server can be used to record you did see a message, which you likely don't want if the message is spam or malicious.

**(28) How can I manage status bar notifications?**
|
|
|
|
|
|
In the setup you'll find a button *Manage notifications* to directly navigate to the Android notifications settings for FairEmail.
|
|
|
|
|
|
On Android 8.0 Oreo and later you can manage the properties of the individual notification channels,
|
|
|
for example to set a specific notification sound or to show notifications on the lock screen.
|
|
|
|
|
|
FairEmail has the following notification channels:
|
|
|
|
|
|
* Service: used for the notification of the synchronize service, see also [this FAQ](#user-content-faq2)
|
|
|
* Send: used for the notification of the send service
|
|
|
* Notifications: used for new message notifications
|
|
|
* Warning: used for warning notifications
|
|
|
* Error: used for error notifications
|
|
|
|
|
|
See [here](https://developer.android.com/guide/topics/ui/notifiers/notifications#ManageChannels) for details on notification channels.
|
|
|
In short: tap on the notification channel name to access the channel settings.
|
|
|
|
|
|
On Android before Android 8 Oreo you can set the notification sound in the settings.
|
|
|
|
|
|
See [this FAQ](#user-content-faq21) if your device has a notification light.

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

**(30) How can I use the provided quick settings?**
|
|
|
|
|
|
There are quick settings (settings tiles) available to:
|
|
|
|
|
|
* globally enable/disable synchronization
|
|
|
* show the number of new messages and marking them as seen (not read)
|
|
|
|
|
|
Quick settings require Android 7.0 Nougat or later.
|
|
|
The usage of settings tiles is explained [here](https://support.google.com/android/answer/9083864).

**(31) How can I use the provided shortcuts?**
|
|
|
|
|
|
There are shortcuts available to:
|
|
|
|
|
|
* compose a new message to a favorite contact
|
|
|
* setup accounts, identities, etc
|
|
|
|
|
|
Shortcuts require Android 7.1 Nougat or later.
|
|
|
The usage of shortcuts is explained [here](https://support.google.com/android/answer/2781850).

**(32) How can I check if reading email is really safe?**
|
|
|
|
|
|
You can use the [Email Privacy Tester](https://www.emailprivacytester.com/) for this.
|
|
|
|
|
|
<br />
|
|
|
|
|
|
<a name="faq33"></a>
|
|
|
**(33) Why are edited sender addresses not working?**
|
|
|
|
|
|
Most providers accept validated addresses only when sending messages to prevent spam.
|
|
|
|
|
|
For example Google modifies the message headers like this:
|
|
|
|
|
|
```
|
|
|
From: Somebody <somebody@example.org>
|
|
|
X-Google-Original-From: Somebody <somebody+extra@example.org>
|
|
|
```
|
|
|
|
|
|
This means that the edited sender address was automatically replaced by a validated address before sending the message.
|
|
|
|
|
|
Note that this is independent of receiving messages.
|
|
|
|
|
|
<br />
|
|
|
|
|
|
<a name="faq34"></a>
|
|
|
**(34) How are identities matched?**
|
|
|
|
|
|
Identities are as expected matched by account.
|
|
|
For incoming messages the *to* and *cc* address will be checked and for outgoing messages the *from* addresses will be checked.
|
|
|
Archived messages will be considered as incoming messages, but additionally the *from* address will be checked.
|
|
|
|
|
|
The matched address will be shown as *via* in the addresses section.
|
|
|
|
|
|
Matched identities can be used to color code messages.
|
|
|
The identity color takes precedence over the account color.
|
|
|
Setting identity colors is a pro feature.

|
|
|
**(35) Why should I be careful with viewing images, attachments and the original message?**
|
|
|
|
|
|
Viewing remotely stored images (see also [this FAQ](#user-content-faq27)) might not only tell the sender that you have seen the message,
|
|
|
but will also leak your IP address.
|
|
|
|
|
|
Opening attachments or viewing an original message might execute scripts,
|
|
|
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.
|
|
|
|
|
|
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.

**(36) How are settings files encrypted?**
|
|
|
|
|
|
Short version: AES 256 bit
|
|
|
|
|
|
Long version:
|
|
|
|
|
|
* The 256 bit key is generated with *PBKDF2WithHmacSHA1* using a 128 bit secure random salt and 65536 iterations
|
|
|
* The cipher is *AES/CBC/PKCS5Padding*

**(37) How are passwords stored?**
|
|
|
|
|
|
All supported Android versions [encrypt all user data](https://source.android.com/security/encryption/full-disk.html),
|
|
|
so all data, including usernames, passwords, messages, etc, is stored encrypted.

**(38) Can you help me restore my Play store purchase?**
|
|
|
|
|
|
Google manages all purchases, so as developer I have no control over purchases.
|
|
|
So, the only thing I can do, is give some advice:
|
|
|
|
|
|
* Make sure you have an active, working internet connection
|
|
|
* Make sure the Google Play store / Play services are not blocked in any way, for example by a firewall
|
|
|
* Make sure you are logged in with the right Google account and that there is nothing wrong with your Google account
|
|
|
* Open the Play store application and wait at least a minute to give it time to synchronize with the Google servers
|
|
|
* Open FairEmail to check the purchase again
|
|
|
|
|
|
Note that:
|
|
|
|
|
|
* Purchases are stored in the Google cloud and cannot get lost
|
|
|
* There is no time limit on purchases, so they cannot expire
|
|
|
* Google does not expose details (name, e-mail, etc) about buyers to developers
|
|
|
* An application like FairEmail cannot select which Google account to use
|
|
|
|
|
|
If you cannot solve the problem with the purchase, you will have to contact Google about it.

|
**(39) How can I reduce the battery usage of FairEmail?**
|
|
|
|
|
|
First of all, update to [the latest version](https://github.com/M66B/open-source-email/releases/).
|
|
|
|
|
|
It is inevitable that synchronizing messages will use battery power because it requires network access and accessing the messages database.
|
|
|
|
|
|
Reconnecting to an email server will use extra battery power, so an unstable internet connection will result in extra battery usage.
|
|
|
In this case you might want to synchronize periodically, for example each hour, instead of continuously.
|
|
|
|
|
|
Recent Android versions by default report *app usage* as a percentage in the Android battery settings screen.
|
|
|
Confusingly, *app usage* is not the same as *battery usage*.
|
|
|
The app usage will be very high because FairEmail is using a foreground service which is considered as constant app usage by Android.
|
|
|
However, this doesn't mean that FairEmail is constantly using battery power.
|
|
|
The real battery usage can be seen by using the three dot overflow menu *Show full device usage*.
|
|
|
As a rule of thumb the battery usage should be below or in any case not be much higher than *Mobile network standby*.
|
|
|
If this isn't the case, please let me know.
|
|
|
|
|
|
Most of the battery usage, not considering viewing messages, is due to synchronization (receiving and sending) of messages.
|
|
|
So, to reduce the battery usage, set the number of days to synchronize message for to a lower value,
|
|
|
especially if there are a lot of recent messages in a folder.
|
|
|
Long press a folder name in the folders list to access this setting.
|
|
|
|
|
|
If you have at least once a day internet connectivity, it is sufficient to synchronize messages just for one day.
|
|
|
|
|
|
Note that you can set the number of days to *keep* messages for to a higher number than to *synchronize* messages for.
|
|
|
You could for example initially synchronize messages for a large number of days and after this has been completed
|
|
|
reduce the number of days to synchronize messages for, but leave the number of days to keep messages for.
|
|
|
|
|
|
Starred messages will always be synchronized,
|
|
|
which will allow you to keep older messages around while synchronizing messages for a limited number of days.
|
|
|
|
|
|
Disabling the folder option *Automatically download message texts and attachments*
|
|
|
will result in less network traffic and thus less battery usage.
|
|
|
You could disable this option for example for the sent folder and the archive.
|
|
|
|
|
|
Synchronizing messages at night is mostly not useful, so you can save on battery usage by not synchronizing at night.
|
|
|
In the settings you can select a schedule for message synchronization (this is a pro feature). See also [this FAQ](#user-content-faq78).
|
|
|
|
|
|
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,
|
|
|
you can save battery usage while viewing messages by switching to the black theme.

**(40) How can I reduce the network usage of FairEmail?**
|
|
|
|
|
|
You can reduce the network usage basically in the same way as reducing battery usage, see the previous question for suggestions.
|
|
|
|
|
|
Additionally, you can let FairEmail download small messages and attachments on a metered (mobile, paid) connection only
|
|
|
or let FairEmail connect via unmetered connections only in the settings.

|
|
|
**(41) How can I fix the error 'Handshake failed' ?**
|
|
|
|
|
|
There are several possible causes, so please read to the end of this answer.
|
|
|
|
|
|
The error '*Handshake failed ... WRONG_VERSION_NUMBER*' might mean that you are trying to connect to an IMAP or SMTP server
|
|
|
without an encrypted connection, typically using port 143 (IMAP) and port 25 (SMTP).
|
|
|
|
|
|
Most providers provide encrypted connections using different ports, typically port 993 (IMAP) and port 465/587 (SMTP).
|
|
|
|
|
|
If your provider doesn't support encrypted connections, you should ask to make this possible.
|
|
|
If this isn't an option, you could enable *Allow insecure connections* both in the advanced settings AND the account/identity settings.
|
|
|
|
|
|
See also [this FAQ](#user-content-faq4).
|
|
|
|
|
|
The error '*Handshake failed ... SSLV3_ALERT_ILLEGAL_PARAMETER*' is either caused by a bug in the SSL protocol implementation
|
|
|
or by a too short DH key on the email server and can unfortunately not be fixed by FairEmail.

**(42) Can you add a new provider to the list of providers?**
|
|
|
|
|
|
If the provider is used by more than a few people, yes, with pleasure.
|
|
|
|
|
|
The following information is needed:
|
|
|
|
|
|
```
|
|
|
<provider
|
|
|
name="Gmail"
|
|
|
link="https://support.google.com/mail/answer/7126229" // setup instructions
|
|
|
type="com.google"> // this is not needed
|
|
|
<imap
|
|
|
host="imap.gmail.com"
|
|
|
port="993"
|
|
|
starttls="false" />
|
|
|
<smtp
|
|
|
host="smtp.gmail.com"
|
|
|
port="465"
|
|
|
starttls="false" />
|
|
|
```
|
|
|
|
|
|
The EFF [writes](https://www.eff.org/nl/deeplinks/2018/06/announcing-starttls-everywhere-securing-hop-hop-email-delivery):
|
|
|
"*Additionally, even if you configure STARTTLS perfectly and use a valid certificate, there’s still no guarantee your communication will be encrypted.*"
|
|
|
|
|
|
So, pure SSL connections are safer than using [STARTTLS](https://en.wikipedia.org/wiki/Opportunistic_TLS) and therefore preferred.
|
|
|
|
|

|
|
|
|
|
|
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.

|
|
|

|
|
~~Getting contact photos for both the sender and receiver is not really an option because getting contact photo is an expensive operation.~~

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

|
|
|
<a name="faq46"></a>
|
|
|
**(46) Why does the message list keep refreshing?**
|
|
|
|
|
|
If you see a 'spinner' at the top of the message list, the folder is still being synchronized with the remote server.
|
|
|
You can see the progress of the synchronization in the folder list. See the legend about what the icons and numbers mean.
|
|
|
|
|
|
The speed of your device and internet connection and the number of days to synchronize messages for determine how long synchronization will take.
|
|
|
Note that you shouldn't set the number of days to synchronize messages for to more than one day in most cases, see also [this FAQ](#user-content-faq39).

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

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

|
**(50) Can you add an option to synchronize all messages?**
|
|
|
|
|
|
A synchronize all (download all) messages will not be added
|
|
|
because it can easily result in out of memory errors and the available storage space filling up.
|
|
|
It can also easily result in a lot of battery and data usage.
|
|
|
Mobile devices are just not very suitable to download and store years of messages.
|
|
|
You can better use the search on server function (see [question 13](#user-content-faq13)), which is faster and more efficient.
|
|
|
Note that searching through a lot of messages stored locally would only delay searching and use extra battery power.

**(51) How are folders sorted?**
|
|
|
|
|
|
Folders are first sorted on account order (by default on account name)
|
|
|
and within an account with special, system folders on top, followed by folders set to synchronize.
|
|
|
Within each category the folders are sorted on (display) name.
|
|
|
You can set the display name by long pressing a folder in the folder list and selecting *Edit properties*.
|
|
|
|
|
|
The navigation (hamburger) menu item *Order folders* in the setup can be used to manually order the folders.

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

|
**(53) Can you stick the message action bar to the top/bottom?**
|
|
|
|
|
|
The message action bar works on a single message and the bottom action bar works on all the messages in the conversation.
|
|
|
Since there is often more than one message in a conversation, this is not possible.
|
|
|
Moreover, there are quite some message specific actions, like forwarding.
|
|
|
|
|
|
You can use the *Home* button to quickly go to the top of the message.

|
|
|
**(54) How do I use a namespace prefix?**
|
|
|
|
|
|
A namespace prefix is used to automatically remove the prefix providers sometimes add to folder names.
|
|
|
|
|
|
For example the Gmail spam folder is called:
|
|
|
|
|
|
```
|
|
|
[Gmail]/Spam
|
|
|
```
|
|
|
|
|
|
By setting the namespace prefix to *[Gmail]* FairEmail will automatically remove *[Gmail]/* from all folder names.

<a name="faq55"></a>
|
|
|
**(55) How can I mark all messages as read / move or delete all messages?**
|
|
|
|
|
|
You can use multiple select for this.
|
|
|
Long press the first message, don't lift your finger and slide down to the last message.
|
|
|
Then use the three dot action button to execute the desired action.

**(56) Can you add support for JMAP?**
|
|
|
|
|
|
There are almost no providers offering the [JMAP](https://jmap.io/) protocol,
|
|
|
so it is not worth a lot of effort to add support for this to FairEmail.
|
|
|
|
|

<a name="faq57"></a>
|
|
|
**(57) Can I use HTML in signatures?**
|
|
|
|
|
|
Yes, you can use HTML in signatures if you paste HTML formatted text into the signature field or use the *Edit as HTML* button.
|
|
|
|
|
|
See [here](https://stackoverflow.com/questions/44410675/supported-html-tags-on-android-textview) for which HTML tags are supported.
|
|
|
|
|
|
You can for example paste this into the signature field:
|
|
|
|
|
|
This is *italic*, this is *bold* and this is [a link](https://example.org).
|
|
|
|
|
|
Alternatively, you can use the button *Edit as HTML*.

**(58) What does an open/closed email icon mean?**
|
|
|
|
|
|
The email icon in the folder list can be open (outlined) or closed (solid):
|
|
|
|
|
|
|
|
|
|
|
|
Message bodies and attachments are not downloaded by default.

**(59) Can original messages be opened in the browser?**
|
|
|
|
|
|
For security reasons the files with the original message texts are not accessible to other apps, so this is not possible.
|
|
|
In theory the [Storage Access Framework](https://developer.android.com/guide/topics/providers/document-provider) could be used to share these files,
|
|
|
but even Google's Chrome cannot handle this.

**(60) Did you know ... ?**
|
|
|
|
|
|
* Did you know that starred messages are always synchronized/kept?
|
|
|
* Did you know that you can long press the 'write message' icon to go to the drafts folder?
|
|
|
* Did you know that you can long press the account name in the navigation menu to go to the inbox of that account?
|
|
|
* Did you know there is an advanced option to mark messages read when they are moved and that archiving and trashing is also moving?
|
|
|
* Did you know that you can select text (or an email address) in any app on recent Android versions and let FairEmail search for it? You'll need to set a primary account and an archive folder for this to work, so FairEmail knows where to search. There will be 'FairEmail' in the menu with copy, cut, etc.
|
|
|
* Did you know that FairEmail has a tablet mode? Rotate your device in landscape mode and conversation threads will be opened in a second column if there is enough screen space.
|
|
|
* Did you know that you can long press a reply template to create a draft message from the template?
|
|
|
* Did you know that you can long press, hold and swipe to select a range of messages?
|
|
|
* Did you know that you can retry sending messages by using pull-down-to-refresh in the outbox?
|
|
|
* Did you know that you can swipe a conversation left or right to go to the next or previous conversation?
|
|
|
* Did you know that you can tap on an image to see where it will be downloaded from?
|
|
|
* Did you know that you can long press the folder icon in the action bar to select an account?

|
|
|
**(61) Why are some messages shown dimmed?**
|
|
|
|
|
|
Messages shown dimmed are locally moved messages for which the move is not confirmed by the server yet.
|
|
|
This can happen when the folder is set to not synchronize, when there is no connection to the server or when the messages are too old to be synchronized.
|
|
|
Eventually, these messages will be synchronized when the connection to the server is restored or will be deleted if they are too old to be synchronized.
|
|
|
|
|
|
You can view these messages, but you cannot move these messages again until the previous move has been confirmed by the server.
|
|
|
|
|
|
Some providers don't keep track of sent messages or you might be using an SMTP server not related to the provider.
|
|
|
This will result in messages in the sent folder never to be synchronized.
|
|
|

**(62) Which authentication methods are supported?**
|
|
|
|
|
|
The following authentication methods are supported and used in this order:
|
|
|
|
|
|
* LOGIN
|
|
|
* PLAIN
|
|
|
* NTLM (untested)
|
|
|
|
|
|
SASL authentication methods, like CRAM-MD5, are not supported
|
|
|
because [JavaMail for Android](https://javaee.github.io/javamail/Android) does not support SASL authentication.
|
|
|
If using secure connections, a must today, there is little value in using CRAM-MD5 anyway.
|
|
|
|
|
|
If your provider requires an unsupported authentication method, you'll likely get the error message *authentication failed*.

**(63) How are images resized for displaying on screens?**
|
|
|
|
|
|
Large inline or attached [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics) and [JPEG](https://en.wikipedia.org/wiki/JPEG) images
|
|
|
will automatically be resized for displaying on screens.
|
|
|
This is because email messages are limited in size, depending on the provider mostly between 10 and 50 MB.
|
|
|
Images will by default be resized to a maximum width and height of about 1440 pixels and saved with a compression ratio of 90 %.
|
|
|
Images are scaled down using whole number factors to reduce memory usage and to retain image quality.
|
|
|
There is an advanced option to disable automatically resizing and to set the target image size.

**~~(64) Can you add custom actions for swipe left/right?~~**
|
|
|
|
|
|
~~The most natural thing to do when swiping a list entry left or right is to remove the entry from the list.~~
|
|
|
~~The most natural action in the context of an email app is moving the message out of the folder to another folder.~~
|
|
|
~~You can select the folder to move to in the account settings.~~
|
|
|
|
|
|
~~Other actions, like marking messages read and snoozing messages are available via multiple selection.~~
|
|
|
~~You can long press a message to start multiple selection. See also [this question](#user-content-faq55).~~
|
|
|
|
|
|
~~Swiping left or right to mark a message read or unread is unnatural because the message first goes away and later comes back in a different shape.~~
|
|
|
~~Note that there is an advanced option to mark messages automatically read on moving,~~
|
|
|
~~which is in most cases a perfect replacement for the sequence mark read and move to some folder.~~
|
|
|
~~You can also mark messages read from new message notifications.~~
|
|
|
|
|
|
~~If you want to read a message later, you can hide it until a specific time by using the *snooze* menu.~~

**(65) Why are some attachments shown dimmed?**
|
|
|
|
|
|
Inline (image) attachments are shown dimmed.
|
|
|
[Inline attachments](https://tools.ietf.org/html/rfc2183) are supposed to be downloaded and shown automatically,
|
|
|
but since FairEmail doesn't always download attachments automatically, see also [this FAQ](#user-content-faq40),
|
|
|
FairEmail shows all attachment types. To distinguish inline and regular attachments, inline attachments are shown dimmed.

|
|
|
|
|
|
Multiple select one of more conversations (long press to start multiple selecting), tap the three dot button and select *Snooze ...*.
|
|
|
Alternatively, use the *Snooze ...* 'more' menu in the expanded message view.
|
|
|
Select the time the conversation(s) should snooze and confirm by tapping OK.
|
|
|
The conversations will be hidden for the selected time and shown again afterwards.
|
|
|
You will receive a new message notification as reminder.
|
|
|
|
|
|
You can show snoozed messages by using the *Snoozed* item in the three dot overflow menu.
|
|
|
|
|
|
You can tap on the small snooze icon to see until when a conversation is snoozed.
|
|
|
|
|
|
By selecting a zero snooze duration you can cancel snoozing.

**~~(68) Why can Adobe Acrobat reader not open PDF attachments / Microsoft apps not open attached documents?~~**
|
|
|
|
|
|
~~Adobe Acrobat reader and Microsoft apps still expects full access to all stored files,~~
|
|
|
~~while apps should use the [Storage Access Framework](https://developer.android.com/guide/topics/providers/document-provider) since Android KitKat (2013)~~
|
|

~~to have access to actively shared files only. This is for privacy and security reasons.~~
|
|
|
|

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

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

**(70) When will messages be auto expanded?**
|
|
|
|
|
|
When navigation to a conversation one message will be expanded if:
|
|
|
|
|
|
* There is just one message in the conversation
|
|
|
* There is exactly one unread message in the conversation
|
|
|
|
|
|
There is one exception: the message was not downloaded yet
|
|
|
and the message is too large to download automatically on a metered (mobile) connection.
|
|
|
You can set or disable the maximum message size on the 'connection' settings tab.
|
|
|
|
|
|
Duplicate (archived) messages, trashed messages and draft messages are not counted.

|
|
**(71) How do I use filter rules?**
|
|
|
|
|
|
You can edit filter rules by long pressing a folder in the folder list.
|
|
|
The rules will be applied to new messages received in the folder, not to existing messages.
|
|
|
|
|
|
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.
|
|
|
|
|
|
All the conditions of a rule need to be true for a filter rule to be executed.
|
|
|
Conditions are optional, but there needs to be at least one condition.
|
|
|
You can use multiple rules, possibly with a *stop processing*, for an *or* condition.
|
|
|
|
|
|
Matching is not case sensitive, unless you use [regular expressions](https://en.wikipedia.org/wiki/Regular_expression).
|
|
|
|
|
|
In the *more* message menu there is an item to create a rule for a received message with the most common conditions filled in.
|
|
|
|
|
|
You can select one of these actions to apply to matching messages:
|
|
|
|
|
|
* Mark as read
|
|
|
* Mark as unread
|
|
|
* Add star
|
|
|
* Move
|
|
|
* Copy
|
|
|
* Reply template
|
|
|
* Automation
|
|
|
|
|
|
Filter rules are applied direct after the message header has been fetched, before the message text has been downloaded,
|
|
|
so it is not possible to apply filter rules to the message text.
|
|
|
Note that large message texts are downloaded on demand on a metered connection to save data.
|
|
|
|
|
|
To debug rules you can long press *Operations* to see logging about the evaluation of rule conditions.
|
|
|
Since message headers are not downloaded and stored by default to save on battery and data usage and to save storage space
|
|
|
it is not possible to preview which messages would match the rule conditions.
|
|
|
|
|
|
Using filter rules is a pro feature.

**(72) What are primary accounts/identities?**
|
|
|
|
|
|
The primary account is used when the account is ambiguous, for example when starting a new draft from the unified inbox.
|
|
|
|
|
|
Similarly, the primary identity of an account is used when the identity is ambiguous.
|
|
|
|
|
|
There can be just one primary account and there can be just one primary identity per account.

<a name="faq73"></a>
|
|
|
**(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.
|
|
|
|
|
|
<br />
|
|
|
|
|
|
<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.
|
|
|
FairEmail shows all these messages, except for one, dimmed, to indicate that these messages are in fact the same message.
|
|
|
|
|
|
Gmail allows one message to have multiple labels, which are presented to FairEmail as folders.
|
|
|
This means that messages with multiple labels will be shown multiple times as well.
|
|
|
|
|
|
You can hide duplicate messages by disabling *Show duplicates* in the three dots overflow menu.

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

|
which is why I develop apps for Android only.

**(76) What does 'Clear local messages' ?**
|
|
|
|
|
|
The folder menu *Clear local messages* removes messages from the device which are present on the server too.
|
|
|
It does not delete messages from the server.
|
|
|
This can be useful after changing the folder settings to not download the message content (text and attachments), for example to save space.
|
|
|
|
|
|
<br />
|
|
|
|
|
|
<a name="faq77"></a>
|
|
|
**(77) Why are messages sometimes shown with a small delay?**
|
|
|
|
|
|
Depending on the speed of your device (processor speed and maybe even more memory speed) messages might be displayed with a small delay.
|
|
|
FairEmail is designed to dynamically handle a large number of messages without running out of memory.
|
|
|
This means that messages needs to be read from a database and that this database needs to be watched for changes, both of which might cause small delays.
|
|
|
|
|
|
Some convenience features, like grouping messages to display conversation threads and determining the previous/next message, take a little extra time.
|
|
|
Note that there is no *the* next message because in the meantime a new message might have been arrived.
|
|
|
|
|
|
When comparing the speed of FairEmail with similar apps this should be part of the comparison.
|
|
|
It is easy to write a similar, faster app which just displays a lineair list of messages while possible using too much memory,
|
|
|
but it is not so easy to properly manage resource usage and to offer more advanced features like conversation threading.
|
|
|
|
|
|
FairEmail is based on the state-of-the-art [Android architecture components](https://developer.android.com/topic/libraries/architecture/),
|
|
|
so there is little room for performance improvements.

**(78) How do I use schedules?**
|
|
|
|
|
|
In the settingss you can enable scheduling and set the time to turn synchronizing automatically on and off.
|
|
|
|
|
|
An end time equal to or earlier than the start time is considered to be 24 hours later.
|
|
|
|
|
|
Turning FairEmail on or off, for example by using [a quick settings tile](#user-content-faq30), will not turn scheduling off.
|
|
|
This means that the next schedule event will still turn FairEmail on or off.
|
|
|
|
|
|
You can also automate turning synchronization on and off by sending these commands to FairEmail:
|
|
|
|
|
|
```
|
|
|
(adb shell) am startservice -a eu.faircode.email.ENABLE
|
|
|
(adb shell) am startservice -a eu.faircode.email.DISABLE
|
|
|
```
|
|
|
|
|
|
Sending these commands will automatically turn scheduling off.
|
|
|
|
|
|
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
|
|
|
```
|
|
|
|
|
|
Automation can be used for more advanced schedules,
|
|
|
like for example multiple synchronization periods per day or different synchronization periods for different days.
|
|
|
|
|
|
Scheduling is a pro feature.

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 not be disturbed or to save on battery usage,
|
|
|
just disable synchronization in the advanced option (accessible via the button at the bottom of the setup screen).
|
|
|
This will stop the background service which takes care of automatic synchronization and will remove the associated status bar notification.
|
|
|
You can use pull-down-to-refresh in a folder or use the folder menu *Synchronize now* to manually synchronize messages.
|
|
|
This will start the synchronization service for 60 seconds for all configured accounts.
|
|
|
|
|
|
The synchronization process will also be started to execute [operations](#user-content-faq3),
|
|
|
for example to mark a message read, move a message or store a draft.
|
|
|
This is to keep the local and remote message store synchronized.

**(80) How can I fix 'Unable to load BODYSTRUCTURE' ?**
|
|
|
|
|
|
The error message *Unable to load BODYSTRUCTURE* is caused by bugs in the email server,
|
|
|
see [here](https://javaee.github.io/javamail/FAQ#imapserverbug) for more details.
|
|
|
|
|
|
FairEmail already tries to workaround these bugs, but if this fail you'll need to ask for support from your provider.

**~~(81) Can you make the background of the original message dark in the dark theme?~~**
|
|
|
|
|
|
~~The original message is shown as the sender has sent it, including all colors.~~
|
|
|
~~Changing the background color would not only make the original view not original anymore, it can also result in unreadable messages.~~

**(82) What is a tracking image?**
|
|
|
|
|
|
Please see [here](https://en.wikipedia.org/wiki/Web_beacon) about what a tracking image exactly is.
|
|
|
In short tracking images keep track if you opened a message.
|
|
|
|
|
|
FairEmail automatically recognizes images with a surface of less than or equal to 25 pixels as tracking images.
|
|
|
FairEmail automatically removes the link of such images, which makes such images appear as broken, and adds a remark about this below the image.

|
**(83) What does 'User is authenticated but not connected' mean?**
|
|
|
|
|
|
This is likely a confusing Microsoft Exchange (Office365) message telling that the password is invalid.
|
|
|
|
|
|
Less likely is that you are synchronizing too many folders.
|
|
|
This can also happen due to abruptly losing connectivity resulting in not properly closing connections.
|
|
|
|
|
|
So, double check the password or reduce the number of folders to synchronize.

<a name="faq84"></a>
|
|
|
**(84) What are local contacts for?**
|
|
|
|
|
|
The main use of the local contacts storage is to offer auto completion when no contacts permission has been granted to FairEmail.
|
|
|
|
|
|
Another use is to generate [shortcuts](#user-content-faq31) on recent Android versions to quickly send a message to frequently contacted people.
|
|
|
This is also why the number of times contacted and the last time contacted is being recorded
|
|
|
and why you can make a contact a favorite or exclude it from favorites by long pressing it.
|
|
|
|
|
|
The list of contacts is sorted on number of times contacted and the last time contacted.
|
|
|
|
|
|
Local contacts will be used for auto completion only when no contacts permission has been granted to FairEmail.
|
|
|
You can revoke contacts permission in the Android app settings.

|
|
|
**(85) Why is an identity not available?**
|
|
|
|
|
|
An identity is available for sending a new message or replying or forwarding an existing message only if:
|
|
|
|
|
|
* the identity is set to synchronize (send messages)
|
|
|
* the associated account is set to synchronize (receive messages)
|
|
|
* the associated account has a drafts folder
|
|
|
|
|
|
FairEmail will try to select the best identity based on the *to* address of the message replied to / being forwarded.

<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! account?**
|
|
|
|
|
|
For the correct settings, see [here](https://help.yahoo.com/kb/SLN4075.html).
|
|
|
|
|
|
You might need to enable "*less secure sign in*" for "*outdated*" apps,
|
|
|
see [here](https://help.yahoo.com/kb/grant-temporary-access-outdated-apps-account-settings-sln27791.html) for more information.
|
|
|
You can directly access this setting [here](https://login.yahoo.com/account/security#less-secure-apps).
|
|
|
|
|
|
Note that FairEmail is using the standard [IMAP protocol](https://en.wikipedia.org/wiki/Internet_Message_Access_Protocol), which is really not outdated.

|
|
|
**(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.

|
<a name="faq90"></a>
|
|
|
**(90) Why are some texts linked while not being a link?**
|
|
|
|
|
|
FairEmail will automatically link not linked web [IRI](https://nl.wikipedia.org/wiki/Internationalized_resource_identifier)s for your convenience.
|
|
|
However, texts and links are not easily distinguished,
|
|
|
especially not with lots of [top level domains](https://en.wikipedia.org/wiki/List_of_Internet_top-level_domains) being words.
|
|
|
This is why texts with dots are sometimes incorrectly recognized as links, which is better than not recognizing some links.

**~~(91) Can you add periodical synchronization to save battery power?~~**
|
|
|
|
|
|
~~Synchronizing messages is an expensive proces because the local and remote messages need to be compared,~~
|
|
|
~~so periodically synchronizing messages will not result in saving battery power, more likely the contrary.~~
|
|
|
|

|
|
|
**(92) Can you add spam filtering, verification of the DKIM signature and SPF authorization?**
|
|
|
|
|
|
Spam filtering, verification of the [DKIM](https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail) signature
|
|
|
and [SPF](https://en.wikipedia.org/wiki/Sender_Policy_Framework) authorization is a task of email servers, not of an email client.
|
|
|
|
|
|
However, FairEmail can show a small vertical warning stripe at the end of the message header
|
|
|
if DKIM, SPF or [DMARC](https://en.wikipedia.org/wiki/DMARC) authentication failed on the receiving server.
|
|
|
You can enable this in the settings.
|
|
|
|
|

|
|
|
<a name="faq93"></a>
|
|
|
**(93) Can you allow installation on external storage?**
|
|
|
|
|
|
FairEmail uses services and alarms, provides widgets and listens for the boot completed event to be started on device start, so this is not possible.
|
|
|

|
|
**(94) What does the red/orange stripe at the end of the header mean?**
|
|
|
|
|
|
The red/orange stripe at the left side of the header means that the DKIM, SPF or DMARC authentication failed.
|
|
|

|
|
|
**(95) Why are not all apps shown when selecting an attachment or image?**
|
|
|
|
|
|
For privacy and security reasons FairEmail does not have permissions to directly access files,
|
|
|
instead the Storage Access Framework, available and recommended since Android 4.4 KitKat (released in 2013), is used to select files.
|
|
|
If an app is listed depends on if the app implements a [document provider](https://developer.android.com/guide/topics/providers/document-provider).
|
|
|
|
|
|
Android Q will make it harder and maybe even impossible to directly access files,
|
|
|
see [here](https://developer.android.com/preview/privacy/scoped-storage) and [here](https://www.xda-developers.com/android-q-storage-access-framework-scoped-storage/) for more details.

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

|
**(97) What is 'cleanup' ?**
|
|
|
|
|
|
About each four hours FairEmail runs a cleanup job that:
|
|
|
|
|
|
* Removes old message texts
|
|
|
* Removes old attachment files
|
|
|
* Removes old image files
|
|
|
* Removes old local contacts
|
|
|
* Removes old log entries
|
|
|
|
|
|
Note that the cleanup job will only run when the synchronize service is active.

**(98) Why can I still pick contacts after revoking contacts permissions?**
|
|
|
|
|
|
After revoking contacts permissions Android does not allow FairEmail access to your contacts anymore.
|
|
|
However, picking contacts is delegated to and done by Android and not by FairEmail, so this will still be possible without contacts permissions.

**(99) Can you add a rich text or markdown editor?**
|
|
|
|
|
|
FairEmail provides common text formatting (bold, italic, underline, text size and color) via the Android text selection menu.
|
|
|
|
|
|
A [Rich text](https://en.wikipedia.org/wiki/Formatted_text) or [Markdown](https://en.wikipedia.org/wiki/Markdown) editor
|
|
|
would not be used by many people on a small mobile device and, more important,
|
|
|
Android doesn't support a rich text editor and most rich text editor open source projects are abandoned.
|
|
|
See [here](https://forum.xda-developers.com/showpost.php?p=79061829&postcount=4919) for some more details about this.

**(100) How can I synchronize Gmail categories?**
|
|
|
|
|
|
You can synchronize Gmail categories by creating filters to label categorized messages:
|
|
|
|
|
|
* Create a new filter via Gmail > Settings (wheel) > Filters and Blocked Addresses > Create a new filter
|
|
|
* Enter a category search (see below) in the *Has the words* field and click *Create filter*
|
|
|
* Check *Apply the label* and select a label and click *Create filter*
|
|
|
|
|
|
Possible categories:
|
|
|
|
|
|
```
|
|
|
category:social
|
|
|
category:updates
|
|
|
category:forums
|
|
|
category:promotions
|
|
|
```
|
|
|
|
|
|
Pull down the folders list in FairEmail to refresh the folder list
|
|
|
and long press the category folders to enable synchronization.

**(101) What does the blue/orange dot at the bottom of the conversations mean?**
|
|
|
|
|
|
The dot shows the relative position of the conversation in the message list.
|
|
|
The dot will be show orange when the conversation is the first or last in the message list, else it will be blue.
|
|
|
The dot is meant as an aid when swiping left/right to go to the previous/next conversation.
|

<a name="faq102"></a>
|
|
|
**(102) How can I enable auto rotation of images?**
|
|
|
|
|
|
Images will automatically be rotated when automatic resizing of images is enabled in the settings (enabled by default).
|
|
|
However, automatic rotating depends on the [Exif](https://en.wikipedia.org/wiki/Exif) information to be present and to be correct,
|
|
|
which is not always the case. Particularly not when taking a photo with a camara app from FairEmail.
|
|
|
|
|
|
Note that only [JPEG](https://en.wikipedia.org/wiki/JPEG) and [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics) images can contain Exif information.

|
|
**(103) How can I record audio?**
|
|
|
|
|
|
You can record audio if you have a recording app installed
|
|
|
which supports the [RECORD_SOUND_ACTION](https://developer.android.com/reference/android/provider/MediaStore.Audio.Media#RECORD_SOUND_ACTION) intent.
|
|
|
If no supported app is installed, FairEmail will not show a record audio action/icon.
|
|
|
|
|
|
Unfortunately and surprisingly, most recording apps do not seem to support this intent (they should).

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

|
|
* Error reports will help improve FairEmail
|
|
|
* Error reporting is optional and opt-in
|
|
|
* Error reporting can be enabled/disabled in the settings, section miscellaneous
|
|
|
* Error reports will automatically be sent anonymously to [Bugsnag](https://www.bugsnag.com/)
|
|
|
* Bugsnag for Android is [open source](https://github.com/bugsnag/bugsnag-android)
|
|
|
* See [here](https://docs.bugsnag.com/platforms/android/automatically-captured-data/) about what data will be sent in case of errors
|
|
|
* See [here](https://docs.bugsnag.com/legal/privacy-policy/) for the privacy policy of Bugsnag

**(105) How does the roam-like-at-home option work?**
|
|
|
|
|
|
FairEmail will check if the country code of the SIM card and the country code of the network
|
|
|
are in the [EU roam-like-at-home countries](https://en.wikipedia.org/wiki/European_Union_roaming_regulations#Territorial_extent)
|
|
|
and assumes no roaming if the country codes are equal and the advanced roam-like-at-home option is enabled.
|
|
|
|
|
|
So, you don't have to disable this option if you don't have an EU SIM or are not connected to an EU network.

|
|
|
**(107) How do I use colored stars?**
|
|
|
|
|
|
You can set a colored star via the *more* message menu, via multiple selection (started by long pressing a message)
|
|
|
or automatically by using [rules](#user-content-faq71).
|
|
|
|
|
|
You need to know that colored stars are not supported by the IMAP protocol and can therefore not be synchronized to an email server.
|
|
|
This means that colored stars will not be visible in other email clients and will be lost on downloading messages again.
|
|
|
However, the stars (without color) will be synchronized and will be visible in other email clients, when supported.
|
|
|
|
|
|
Some email clients use IMAP keywords for colors.
|
|
|
However, not all servers support IMAP keywords and besides that there are no standard keywords for colors.

|
|
**(108) Can you add permanently delete messages from any folder?**
|
|
|
|
|
|
When you delete messages from a folder the messages will be moved to the trash folder, so you have a chance to restore the messages.
|
|
|
You can permanently delete messages from the trash folder.
|
|
|
Permanently delete messages from other folders would defeat the purpose of the trash folder, so this will not be added.

|
**~~(109) Why is 'select account' available in official versions only?~~**
|
|
|
|
|
|
~~Using *select account* to select and authorize Google accounts require special permission from Google for security and privacy reasons.~~
|
|
|
~~This special permission can only be acquired for apps a developer manages and is responsible for.~~
|
|
|
~~Third party builds, like the F-Droid builds, are managed by third parties and are the responsibility of these third parties.~~
|
|
|
~~So, only these third parties can acquire the required permission from Google.~~
|
|
|
~~Since these third parties do not actually support FairEmail, they are most likely not going to request the required permission.~~
|
|
|
|
|
|
~~You can solve this in two ways:~~
|
|
|
|
|
|
* ~~Switch to the official version of FairEmail, see [here](https://github.com/M66B/open-source-email/blob/master/README.md#downloads) for the options~~
|
|
|
* ~~Use app specific passwords, see [this FAQ](#user-content-faq6)~~
|
|
|
|
|
|
~~Using *select account* in third party builds is not possible in recent versions anymore.~~
|
|
|
~~In older versions this was possible, but it will now result in the error *UNREGISTERED_ON_API_CONSOLE*.~~

|
|
|
**(110) Why are (some) messages empty and/or attachments corrupt?**
|
|
|
|
|
|
Empty messages and/or corrupt attachments are probably being caused by a bug in the server software.
|
|
|
Older Microsoft Exchange software is known to cause this problem.
|
|
|
Mostly you can workaround this by disabling *Partial fetch* in the advanced account settings.
|
|
|
|
|
|
After disabling this setting, you can use the message 'more' (three dots) menu to 'resync' empty messages.
|
|
|
Alternatively, you can *Delete local messages* by long pressing the folder(s) in the folder list and synchronize all messages again.

|
**(111) Can you add OAuth authentication?**
|
|
|
|
|
|
(X)OAuth authentication, formerly available as *Select account* for Google accounts, requires creating an online (Google, Microsoft, etc) app,
|
|
|
which would make authentication for many people dependent on one (developer) account, which is a bad idea.
|
|
|
|
|
|
See also [this related article](https://arstechnica.com/gadgets/2019/06/gmails-api-lockdown-will-kill-some-third-party-app-access-starting-july-15/).
|
|
|
|
|
|
Outlook and Hotmail do not properly support OAuth for IMAP/SMTP connections.
|
|
|
[MSAL](https://github.com/AzureAD/microsoft-authentication-library-for-android) is supported for business accounts only
|
|
|
and requires embedding a client secret in the app, which is not a good idea for an open source app.
|
|
|
