```
This means that the edited sender address was automatically replaced by a verified address before sending the message.
Note that this is independent of receiving messages.
**(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.
The matched address will be shown as *via* in the addresses section of received messages (between the message header and message text).
Note that identities needs to be enabled to be able to be matched and that identities of other accounts will not be considered.
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.
It is possible to configure a [regex](https://en.wikipedia.org/wiki/Regular_expression) in the identity settings to match **the username** of an email address (the part before the @ sign).
Note that the domain name (the parts after the @ sign) always needs to be equal to the domain name of the identity.
If you like to match a catch-all email address, this regex is mostly okay:
```
.*
```
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 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?**
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, but will also leak your IP address. 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).
Opening attachments or viewing an original message might load remote content and 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.
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.
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 ...*.
If you want to reset the default *Open with* apps, please [see here](https://www.androidauthority.com/how-to-set-default-apps-android-clear-621269/).
**(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), so all data, including usernames, passwords, messages, etc, is stored encrypted.
If the device is secured with a PIN, pattern or password, you can make the account and identity passwords visible. If this is a problem because you are sharing the device with other people, consider to use [user profiles](https://www.howtogeek.com/333484/how-to-set-up-multiple-user-profiles-on-android/).
**(39) How can I reduce the battery usage of FairEmail?**
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* and is not even directly related to battery usage!** 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. However, this doesn't mean that FairEmail is constantly using battery power. 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*
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 turn on *Auto optimize* in the receive settings. If this doesn't help, please [ask for support](https://contact.faircode.eu/?product=fairemailsupport).
It is inevitable that synchronizing messages will use battery power because it requires network access and accessing the messages database.
If you are comparing the battery usage of FairEmail with another email client, please make sure the other email client is setup similarly. For example comparing always sync (push messages) and (infrequent) periodic checking for new messages is not a fair comparison.
Reconnecting to an email server will use extra battery power, so an unstable internet connection will result in extra battery usage. Also, some email servers prematurely terminate idle connections, while [the standard](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 because connecting to the server and comparing the local and remote messages are expensive operations.
[On some devices](https://dontkillmyapp.com/) it is necessary to *disable* battery optimizations (setup step 4) to keep connections to email servers open. In fact, leaving battery optimizations enabled can result in extra battery usage for all devices, even though this sounds contradictory!
Most of the battery usage, not considering viewing messages, is due to synchronization (receiving and sending) of messages. So, to reduce the battery usage, set the number of days to synchronize message for to a lower value, especially if there are a lot of recent messages in a folder. Long press a folder name in the folders list and select *Edit properties* to access this setting.
If you have at least once a day internet connectivity, it is sufficient to synchronize messages just for one day.
Note that you can set the number of days to *keep* messages for to a higher number than to *synchronize* messages for. You could for example initially synchronize messages for a large number of days and after this has been completed reduce the number of days to synchronize messages for, but leave the number of days to keep messages for. After decreasing the number of days to keep messages for, you might want to run the cleanup in the miscellaneous settings to remove old files.
In the receive settings you can enable to always synchronize starred messages, which will allow you to keep older messages around while synchronizing messages for a limited number of days.
Disabling the folder option *Automatically download message texts and attachments* will result in less network traffic and thus less battery usage. You could disable this option for example for the sent folder and the archive.
Synchronizing messages at night is mostly not useful, so you can save on battery usage by not synchronizing at night. In the settings you can select a schedule for message synchronization (this is a pro feature).
FairEmail will by default synchronize the folder list on each connection. Since folders are mostly not created, renamed and deleted very often, you can save some network and battery usage by disabling this in the receive settings.
FairEmail will by default check if old messages were deleted from the server on each connection. If you don't mind that old messages that were delete from the server are still visible in FairEmail, you can save some network and battery usage by disabling this in the receive settings.
Some providers don't follow the IMAP standard and don't keep connections open long enough, forcing FairEmail to reconnect often, causing extra battery usage. You can inspect the *Log* via the main navigation menu to check if there are frequent reconnects (connection closed/reset, read/write error/timeout, etc). You can workaround this by lowering the keep-alive interval in the advanced account settings to for example 9 or 15 minutes. Note that battery optimizations need to be disabled in setup step 4 to reliably keep connections alive.
Some providers send every two minutes something like '*Still here*' resulting in network traffic and your device to wake up and causing unnecessary extra battery usage. You can inspect the *Log* via the main navigation menu to check if your provider is doing this. If your provider is using [Dovecot](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.
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.
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:
* 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?**
You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.
It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).
To reduce data usage, you could change these advanced receive settings:
* Check if old messages were removed from the server: disable
* Synchronize (shared) folder list: disable
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.
**(41) How can I fix the error 'Handshake failed' ?**
There are several possible causes, so please read to the end of this answer.
The error '*Handshake failed ... WRONG_VERSION_NUMBER ...*' might mean that you are trying to connect to an IMAP or SMTP server without an encrypted connection, typically using port 143 (IMAP) and port 25 (SMTP), or that a wrong protocol (SSL/TLS or STARTTLS) is being used.
Most providers provide encrypted connections using different ports, typically port 993 (IMAP) and port 465/587 (SMTP).
If your provider doesn't support encrypted connections, you should ask to make this possible. If this isn't an option, you could enable *Allow insecure connections* both in the advanced settings AND the account/identity settings.
See also [this FAQ](#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.
The error '*Handshake failed ... HANDSHAKE_FAILURE_ON_CLIENT_HELLO ...*' might be caused by the provider still using RC4, which isn't supported since [Android 7](https://developer.android.com/about/versions/nougat/android-7.0-changes.html#tls-ssl) anymore.
The error '*Handshake failed ... UNSUPPORTED_PROTOCOL or TLSV1_ALERT_PROTOCOL_VERSION ...*' might be caused by enabling hardening connections in the connection settings or by Android not supporting older protocols anymore, like SSLv3.
Android 8 Oreo and later [do not support](https://developer.android.com/about/versions/oreo/android-8.0-changes#security-all) SSLv3 anymore. There is no way to workaround lacking RC4 and SSLv3 support because it has completely been removed from Android (which should say something).
You can use [this website](https://ssl-tools.net/mailservers) or [this website](https://www.immuniweb.com/ssl/) to check for SSL/TLS problems of email servers.
**(42) Can you add a new provider to the list of providers?**
If the provider is used by more than a few people, yes, with pleasure.
The following information is needed:
```
// questo non è necessario
```
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.
Please make sure receiving and sending messages works properly before contacting me to add a provider.
See below about how to contact me.
**(43) Can you show the original ... ?**
Show original, shows the original message as the sender has sent it, including original fonts, colors, margins, etc. FairEmail does and will not alter this in any way, except for requesting [TEXT_AUTOSIZING](https://developer.android.com/reference/android/webkit/WebSettings.LayoutAlgorithm), which will *attempt* to make small text more readable.
**~~(44) Can you show contact photos / identicons in the sent folder?~~**
~~Contact photos and identicons are always shown for the sender because this is necessary for conversation threads.~~ ~~Getting contact photos for both the sender and receiver is not really an option because getting contact photo is an expensive operation.~~
**(45) How can I fix 'This key is not available. To use it, you must import it as one of your own!' ?**
You'll get the message *This key is not available. To use it, you must import it as one of your own!* when trying to decrypt a message with a public key. To fix this you'll need to import the private key.
**(46) Why does the message list keep refreshing?**
If you see a 'spinner' at the top of the message list, the folder is still being synchronized with the remote server. You can see the progress of the synchronization in the folder list. See the legend about what the icons and numbers mean.
The speed of your device and internet connection and the number of days to synchronize messages for determine how long synchronization will take. Note that you shouldn't set the number of days to synchronize messages for to more than one day in most cases, see also [this FAQ](#user-content-faq39).
**(47) How do I solve the error 'No primary account or no drafts folder' ?**
You'll get the error message *No primary account or no drafts folder* when trying to compose a message while there is no account set to be the primary account or when there is no drafts folder selected for the primary account. This can happen for example when you start FairEmail to compose a message from another app. FairEmail needs to know where to store the draft, so you'll need to select one account to be the primary account and/or you'll need to select a drafts folder for the primary account.
This can also happen when you try to reply to a message or to forward a message from an account with no drafts folder while there is no primary account or when the primary account does not have a drafts folder.
Please see [this FAQ](#user-content-faq141) for some more information.
**~~(48) How do I solve the error 'No primary account or no archive folder' ?~~**
~~You'll get the error message *No primary account or no archive folder* when searching for messages from another app. FairEmail needs to know where to search, so you'll need to select one account to be the primary account and/or you'll need to select a archive folder for the primary account.~~
**(49) How do I fix 'An outdated app sent a file path instead of a file stream' ?**
You likely selected or sent an attachment or image with an outdated file manager or an outdated app which assumes all apps still have storage permissions. For security and privacy reasons modern apps like FairEmail have no full access to all files anymore. This can result into the error message *An outdated app sent a file path instead of a file stream* if a file name instead of a file stream is being shared with FairEmail because FairEmail cannot randomly open files.
You can fix this by switching to an up-to-date file manager or an app designed for recent Android versions. Alternatively, you can grant FairEmail read access to the storage space on your device in the Android app settings. Note that this workaround [won't work on Android Q](https://developer.android.com/preview/privacy/scoped-storage) anymore.
See also [question 25](#user-content-faq25) and [what Google writes about it](https://developer.android.com/training/secure-file-sharing/share-file#RespondToRequest).
**(50) Can you add an option to synchronize all messages?**
You can synchronize more or even all messages by long pressing a folder (inbox) in the folder list of an account (tap on the account name in the navigation menu) and selecting *Synchronize more* in the popup menu.
**(51) How are folders sorted?**
Folders are first sorted on account order (by default on account name) and within an account with special, system folders on top, followed by folders set to synchronize. Within each category the folders are sorted on (display) name. You can set the display name by long pressing a folder in the folder list and selecting *Edit properties*.
The navigation (hamburger) menu item *Order folders* in the setup can be used to manually order the folders.
**(52) Why does it take some time to reconnect to an account?**
There is no reliable way to know if an account connection was terminated gracefully or forcefully. Trying to reconnect to an account while the account connection was terminated forcefully too often can result in problems like [too many simultaneous connections](#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.
Moving the message action bar to the bottom of the message is visually not appealing because there is already a conversation action bar at the bottom of the screen.
Note that there are not many, if any, email apps that display a conversation as a list of expandable messages. This has a lot of advantages, but the also causes the need for message specific actions.
**~~(54) How do I use a namespace prefix?~~**
~~A namespace prefix is used to automatically remove the prefix providers sometimes add to folder names.~~
~~For example the Gmail spam folder is called:~~
```
[Gmail]/Spam
```
~~By setting the namespace prefix to *[Gmail]* FairEmail will automatically remove *[Gmail]/* from all folder names.~~
**(55) How can I mark all messages as read / move or delete all messages?**
You can use multiple select for this. Long press the first message, don't lift your finger and slide down to the last message. Then use the three dot action button to execute the desired action.
**(56) Can you add support for JMAP?**
There are almost no providers offering the [JMAP](https://jmap.io/) protocol, so it is not worth a lot of effort to add support for this to FairEmail.
**(57) Can I use HTML in signatures?**
Yes, you can use [HTML](https://en.wikipedia.org/wiki/HTML). In the signature editor you can switch to HTML mode via the three-dots menu.
Note that if you switch back to the text editor that not all HTML might be rendered as-is because the Android text editor is not able to render all HTML. Similarly, if you use the text editor, the HTML might be altered in unexpected ways.
If you want to use preformatted text, like [ASCII art](https://en.wikipedia.org/wiki/ASCII_art), you should wrap the text in a *pre* element, like this:
```
|\_/|
/ @ @ \
( > º < )
`>>x<<´
/ O \
```
**(58) What does an open/closed email icon mean?**
The email icon in the folder list can be open (outlined) or closed (solid):
Message bodies and attachments are not downloaded by default.
Message bodies and attachments are downloaded by default.
**(59) Can original messages be opened in the browser?**
For security reasons the files with the original message texts are not accessible to other apps, so this is not possible. In theory the [Storage Access Framework](https://developer.android.com/guide/topics/providers/document-provider) could be used to share these files, but even Google's Chrome cannot handle this.
**(60) Did you know ... ?**
* Did you know that starred messages can be synchronized/kept always? (this can be enabled in the receive settings)
* Did you know that you can long press the 'write message' icon to go to the drafts folder?
* Did you know there is an advanced option to mark messages read when they are moved? (archiving and trashing is also moving)
* Did you know that you can select text (or an email address) in any app on recent Android versions and let FairEmail search for it?
* Did you know that FairEmail has a tablet mode? Rotate your device in landscape mode and conversation threads will be opened in a second column if there is enough screen space.
* Did you know that you can long press a reply template to create a draft message from the template?
* Did you know that you can long press, hold and swipe to select a range of messages?
* Did you know that you can retry sending messages by using pull-down-to-refresh in the outbox?
* Did you know that you can swipe a conversation left or right to go to the next or previous conversation?
* Did you know that you can tap on an image to see where it will be downloaded from?
* Did you know that you can long press the folder icon in the action bar to select an account?
* Did you know that you can long press the star icon in a conversation thread to set a colored star?
* Did you know that you can open the navigation drawer by swiping from the left, even when viewing a conversation?
* Did you know that you can long press the people's icon to show/hide the CC/BCC fields and remember the visibility state for the next time?
* Did you know that you can insert the email addresses of an Android contact group via the three dots overflow menu?
* Did you know that if you select text and hit reply, only the selected text will be quoted?
* Did you know that you can long press the trash icons (both in the message and the bottom action bar) to permanently delete a message or conversation? (version 1.1368+)
* Did you know that you can long press the send action to show the send dialog, even if it was disabled?
* Did you know that you can long press the full screen icon to show the original message text only?
**(61) Why are some messages shown dimmed?**
Messages shown dimmed (grayed) are locally moved messages for which the move is not confirmed by the server yet. This can happen when there is no connection to the server or the account (yet). These messages will be synchronized after a connection to the server and the account has been made or, if this never happens, will be deleted if they are too old to be synchronized.
You might need to manually synchronize the folder, for example by pulling down.
You can view these messages, but you cannot move these messages again until the previous move has been confirmed.
Pending [operations](#user-content-faq3) are shown in the operations view accessible from the main navigation menu.
**(62) Which authentication methods are supported?**
The following authentication methods are supported and used in this order:
* LOGIN
* PLAIN
* CRAM-MD5
* XOAUTH2 ([Gmail](https://developers.google.com/gmail/imap/xoauth2-protocol), [Yandex](https://tech.yandex.com/oauth/))
* NTLM (untested)
SASL authentication methods, besides CRAM-MD5, are not supported because [JavaMail for Android](https://javaee.github.io/javamail/Android) does not support SASL authentication.
If your provider requires an unsupported authentication method, you'll likely get the error message *authentication failed*.
[Server Name Indication](https://en.wikipedia.org/wiki/Server_Name_Indication) is supported by [all supported Android versions](https://developer.android.com/training/articles/security-ssl).
**(63) How are images resized for displaying on screens?**
Large inline or attached [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics) and [JPEG](https://en.wikipedia.org/wiki/JPEG) images will automatically be resized for displaying on screens. This is because email messages are limited in size, depending on the provider mostly between 10 and 50 MB. Images will by default be resized to a maximum width and height of about 1440 pixels and saved with a compression ratio of 90 %. Images are scaled down using whole number factors to reduce memory usage and to retain image quality. Automatically resizing of inline and/or attached images and the maximum target image size can be configured in the send settings.
If you want to resize images on a case-by-case basis, you can use [Send Reduced](https://f-droid.org/en/packages/mobi.omegacentauri.SendReduced/) or a similar app.
**~~(64) Can you add custom actions for swipe left/right?~~**
~~The most natural thing to do when swiping a list entry left or right is to remove the entry from the list.~~ ~~The most natural action in the context of an email app is moving the message out of the folder to another folder.~~ ~~You can select the folder to move to in the account settings.~~
~~Other actions, like marking messages read and snoozing messages are available via multiple selection.~~ ~~You can long press a message to start multiple selection. See also [this question](#user-content-faq55).~~
~~Swiping left or right to mark a message read or unread is unnatural because the message first goes away and later comes back in a different shape.~~ ~~Note that there is an advanced option to mark messages automatically read on moving,~~ ~~which is in most cases a perfect replacement for the sequence mark read and move to some folder.~~ ~~You can also mark messages read from new message notifications.~~
~~If you want to read a message later, you can hide it until a specific time by using the *snooze* menu.~~
**(65) Why are some attachments shown dimmed?**
Inline (image) attachments are shown dimmed. [Inline attachments](https://tools.ietf.org/html/rfc2183) are supposed to be downloaded and shown automatically, but since FairEmail doesn't always download attachments automatically, see also [this FAQ](#user-content-faq40), FairEmail shows all attachment types. To distinguish inline and regular attachments, inline attachments are shown dimmed.
**(66) Is FairEmail available in the Google Play Family Library?**
The price of the few pro features is too low, lower than the price of most similar apps, and there are [too many fees and taxes](#user-content-faq19), to justify making FairEmail available in the [Google Play Family Library](https://support.google.com/googleone/answer/7007852). Note that Google promotes the Family libray, but lets developers pay for it.
**(67) How can I snooze conversations?**
Multiple select one of more conversations (long press to start multiple selecting), tap the three dot button and select *Snooze ...*. Alternatively, in the expanded message view use *Snooze ...* in the message three-dots 'more' menu or the timelapse action in the bottom action bar. Select the time the conversation(s) should snooze and confirm by tapping OK. The conversations will be hidden for the selected time and shown again afterwards. You will receive a new message notification as reminder.
It is also possible to snooze messages with [a rule](#user-content-faq71).
You can show snoozed messages by unchecking *Filter out* > *Hidden* in the three dot overflow menu.
You can tap on the small snooze icon to see until when a conversation is snoozed.
By selecting a zero snooze duration you can cancel snoozing.
**~~(68) Why can Adobe Acrobat reader not open PDF attachments / Microsoft apps not open attached documents?~~**
~~Adobe Acrobat reader and Microsoft apps still expects full access to all stored files,~~ ~~while apps should use the [Storage Access Framework](https://developer.android.com/guide/topics/providers/document-provider) since Android KitKat (2013)~~ ~~to have access to actively shared files only. This is for privacy and security reasons.~~
~~You can workaround this by saving the attachment and opening it from the Adobe Acrobat reader / Microsoft app,~~ ~~but you are advised to install an up-to-date and preferably open source PDF reader / document viewer,~~ ~~for example one listed [here](https://github.com/offa/android-foss#-document--pdf-viewer).~~
**(69) Can you add auto scroll up on new message?**
The message list is automatically scrolled up when navigating from a new message notification or after a manual refresh. Always automatically scrolling up on arrival of new messages would interfere with your own scrolling, but if you like you can enable this in the settings.
**(70) When will messages be auto expanded?**
When navigation to a conversation one message will be expanded if:
* There is just one message in the conversation
* There is exactly one unread message in the conversation
There is one exception: the message was not downloaded yet and the message is too large to download automatically on a metered (mobile) connection. You can set or disable the maximum message size on the 'connection' settings tab.
Duplicate (archived) messages, trashed messages and draft messages are not counted.
Messages will automatically be marked read on expanding, unless this was disabled in the individual account settings.
**(71) How do I use filter rules?**
You can edit filter rules by long pressing a folder in the folder list of an account (tap the account name in the navigation/side menu).
New rules will be applied to new messages received in the folder, not to existing messages. You can check the rule and apply the rule to existing messages or, alternatively, long press the rule in the rule list and select *Execute now*.
You'll need to give a rule a name and you'll need to define the order in which a rule should be executed relative to other rules.
You can disable a rule and you can stop processing other rules after a rule has been executed.
The following rule conditions are available:
* Sender contains
* Recipient contains
* Subject contains
* Has attachments
* Header contains
* Day/time between
All the conditions of a rule need to be true for the rule action to be executed. All conditions are optional, but there needs to be at least one condition, to prevent matching all messages. If you want to match all senders or all recipients, you can just use the @ character as condition because all email addresses will contain this character.
Note that email addresses are formatted like this:
`
"Somebody" `
You can use multiple rules, possibly with a *stop processing*, for an *or* or a *not* condition.
Matching is not case sensitive, unless you use [regular expressions](https://en.wikipedia.org/wiki/Regular_expression). Please see [here](https://developer.android.com/reference/java/util/regex/Pattern) for the documentation of Java regular expressions. You can test a regex [here](https://regexr.com/).
Note that a regular expression supports an *or* operator, so if you want to match multiple senders, you can do this:
`
.*alice@example\.org.*|.*bob@example\.org.*|.*carol@example\.org.*`
Note that [dot all mode](https://developer.android.com/reference/java/util/regex/Pattern#DOTALL) is enabled to be able to match [unfolded headers](https://tools.ietf.org/html/rfc2822#section-3.2.3).
You can select one of these actions to apply to matching messages:
* No action (useful for *not*)
* Mark as read
* Mark as unread
* Hide
* Suppress notification
* Snooze
* Add star
* Set importance (local priority)
* Add keyword
* Move
* Copy (Gmail: label)
* Answer/forward (with template)
* Text-to-speech (sender and subject)
* Automation (Tasker, etc)
Rules are applied directly after the message header has been fetched, but before the message text has been downloaded, so it is not possible to apply conditions to the message text. Note that large message texts are downloaded on demand on a metered connection to save on data usage.
If you want to forward a message, consider to use the move action instead. This will be more reliable than forwarding as well because forwarded messages might be considered as spam.
Since message headers are not downloaded and stored by default to save on battery and data usage and to save storage space it is not possible to preview which messages would match a header rule condition.
Some common header conditions (regex):
* *.*Auto-Submitted:.** [RFC3834](https://tools.ietf.org/html/rfc3834)
* *.*Content-Type: multipart/report.** [RFC3462](https://tools.ietf.org/html/rfc3462)
In the three-dots *more* message menu there is an item to create a rule for a received message with the most common conditions filled in.
The POP3 protocol does not support setting keywords and moving or copying messages.
Using rules is a pro feature.
**(72) What are primary accounts/identities?**
The primary account is used when the account is ambiguous, for example when starting a new draft from the unified inbox.
Similarly, the primary identity of an account is used when the identity is ambiguous.
There can be just one primary account and there can be just one primary identity per account.
**(73) Is moving messages across accounts safe/efficient?**
Moving messages across accounts is safe because the raw, original messages will be downloaded and moved and because the source messages will be deleted only after the target messages have been added
Batch moving messages across accounts is efficient if both the source folder and target folder are set to synchronize, else FairEmail needs to connect to the folder(s) for each message.
**(74) Why do I see duplicate messages?**
Some providers, notably Gmail, list all messages in all folders, except trashed messages, in the archive (all messages) folder too. FairEmail shows all these messages in a non obtrusive way to indicate that these messages are in fact the same message.
Gmail allows one message to have multiple labels, which are presented to FairEmail as folders. This means that messages with multiple labels will be shown multiple times as well.
**(75) Can you make an iOS, Windows, Linux, etc version?**
A lot of knowledge and experience is required to successfully develop an app for a specific platform, which is why I develop apps for Android only.
**(76) What does 'Clear local messages' do?**
The folder menu *Clear local messages* removes messages from the device which are present on the server too. It does not delete messages from the server. This can be useful after changing the folder settings to not download the message content (text and attachments), for example to save space.
**(77) Why are messages sometimes shown with a small delay?**
Depending on the speed of your device (processor speed and maybe even more memory speed) messages might be displayed with a small delay. FairEmail is designed to dynamically handle a large number of messages without running out of memory. This means that messages needs to be read from a database and that this database needs to be watched for changes, both of which might cause small delays.
Some convenience features, like grouping messages to display conversation threads and determining the previous/next message, take a little extra time. Note that there is no *the* next message because in the meantime a new message might have been arrived.
When comparing the speed of FairEmail with similar apps this should be part of the comparison. It is easy to write a similar, faster app which just displays a lineair list of messages while possible using too much memory, but it is not so easy to properly manage resource usage and to offer more advanced features like conversation threading.
FairEmail is based on the state-of-the-art [Android architecture components](https://developer.android.com/topic/libraries/architecture/), so there is little room for performance improvements.
**(78) How do I use schedules?**
In the receive settings you can enable scheduling and set a time period and the days of the week *when* messages should be *received*. Note that an end time equal to or earlier than the start time is considered to be 24 hours later.
Automation, see below, can be used for more advanced schedules, like for example multiple synchronization periods per day or different synchronization periods for different days.
It is possible to install FairEmail in multiple user profiles, for example a personal and a work profile, and to configure FairEmail differently in each profile, which is another possibility to have different synchronization schedules and to synchronize a different set of accounts.
It is also possible to create [filter rules](#user-content-faq71) with a time condition and to snooze messages until the end time of the time condition. This way it is possible to *snooze* business related messages until the start of the business hours. This also means that the messages will be on your device for when there is (temporarily) no internet connection.
Note that recent Android versions allow overriding DND (Do Not Disturb) per notification channel and per app, which could be used to (not) silence specific (business) notifications. Please [see here](https://support.google.com/android/answer/9069335) for more information.
For more complex schemes you could set one or more accounts to manual synchronization and send this command to FairEmail to check for new messages:
```
(adb shell) am startservice -a eu.faircode.email.POLL
```
For a specific account:
```
(adb shell) am startservice -a eu.faircode.email.POLL --es account Gmail
```
You can also automate turning receiving messages on and off by sending these commands to FairEmail:
```
(adb shell) am startservice -a eu.faircode.email.ENABLE
(adb shell) am startservice -a eu.faircode.email.DISABLE
```
To enable/disable a specific account:
```
(adb shell) am startservice -a eu.faircode.email.ENABLE --es account Gmail
(adb shell) am startservice -a eu.faircode.email.DISABLE --es account Gmail
```
Note that disabling an account will hide the account and all associated folders and messages.
You can automatically send commands with for example [Tasker](https://tasker.joaoapps.com/userguide/en/intents.html):
```
Nuova attività: Qualcosa di riconoscibile
Categoria d'Azione: Intento Varie/Invia
Azione: eu.faircode.email.ENABLE
Target: Servizio
```
To enable/disable an account with the name *Gmail*:
```
Extra: account:Gmail
```
Account names are case sensitive.
Scheduling is a pro feature.
**(79) How do I use synchronize on demand (manual)?**
Normally, FairEmail maintains a connection to the configured email servers whenever possible to receive messages in real-time. If you don't want this, for example to be not disturbed or to save on battery usage, just disable receiving in the receive settings. This will stop the background service which takes care of automatic synchronization and will remove the associated status bar notification.
You can also enable *Synchronize manually* in the advanced account settings if you want to manually synchronize specific accounts only.
You can use pull-down-to-refresh in a message list or use the folder menu *Synchronize now* to manually synchronize messages.
If you want to synchronize some or all folders of an account manually, just disable synchronization for the folders (but not of the account).
You'll likely want to disabled [browse on server](#user-content-faq24) too.
**~~(80) How do I fix the error 'Unable to load BODYSTRUCTURE' ?~~**
~~The error message *Unable to load BODYSTRUCTURE* is caused by bugs in the email server,~~ ~~see [here](https://javaee.github.io/javamail/FAQ#imapserverbug) for more details.~~
~~FairEmail already tries to workaround these bugs, but if this fail you'll need to ask for support from your provider.~~
**~~(81) Can you make the background of the original message dark in the dark theme?~~**
~~The original message is shown as the sender has sent it, including all colors.~~ ~~Changing the background color would not only make the original view not original anymore, it can also result in unreadable messages.~~
**(82) What is a tracking image?**
Please see [here](https://en.wikipedia.org/wiki/Web_beacon) about what a tracking image exactly is. In short tracking images keep track if you opened a message.
FairEmail will in most cases automatically recognize tracking images and replace them by this icon:
Automatic recognition of tracking images can be disabled in the privacy settings.
**(84) What are local contacts for?**
Local contact information is based on names and addresses found in incoming and outgoing messages.
The main use of the local contacts storage is to offer auto completion when no contacts permission has been granted to FairEmail.
Another use is to generate [shortcuts](#user-content-faq31) on recent Android versions to quickly send a message to frequently contacted people. This is also why the number of times contacted and the last time contacted is being recorded and why you can make a contact a favorite or exclude it from favorites by long pressing it.
The list of contacts is sorted on number of times contacted and the last time contacted.
By default only names and addresses to whom you send messages to will be recorded. You can change this in the send settings.
**(85) Why is an identity not available?**
An identity is available for sending a new message or replying or forwarding an existing message only if:
* the identity is set to synchronize (send messages)
* the associated account is set to synchronize (receive messages)
* the associated account has a drafts folder
FairEmail will try to select the best identity based on the *to* address of the message replied to / being forwarded.
**~~(86) What are 'extra privacy features'?~~**
~~The advanced option *extra privacy features* enables:~~
* ~~Looking up the owner of the IP address of a link~~
* ~~Detection and removal of [tracking images](#user-content-faq82)~~
**(87) What does 'invalid credentials' mean?**
The error message *invalid credentials* means either that the user name and/or password is incorrect, for example because the password was changed or expired, or that the account authorization has expired.
If the password is incorrect/expired, you will have to update the password in the account and/or identity settings.
If the account authorization has expired, you will have to select the account again. You will likely need to save the associated identity again as well.
**(88) How can I use a Yahoo, AOL or Sky account?**
The preferred way to set up a Yahoo account is by using the quick setup wizard, which will use OAuth instead of a password and is therefore safer (and easier as well).
To authorize a Yahoo, AOL, or Sky account you will need to create an app password. For instructions, please see here:
* [for Yahoo](https://help.yahoo.com/kb/generate-third-party-passwords-sln15241.html)
* [for AOL](https://help.aol.com/articles/Create-and-manage-app-password)
* [for Sky](https://www.sky.com/help/articles/getting-started-with-sky-yahoo-mail) (under *Other email apps*)
Please see [this FAQ](#user-content-faq111) about OAuth support.
Note that Yahoo, AOL, and Sky do not support standard push messages. The Yahoo email app uses a proprietary, undocumented protocol for push messages.
Push messages require [IMAP IDLE](https://en.wikipedia.org/wiki/IMAP_IDLE) and the Yahoo email server does not report IDLE as capability:
```
Y1 CAPABILITY
* CAPABILITY IMAP4rev1 ID MOVE NAMESPACE XYMHIGHESTMODSEQ UIDPLUS LITERAL+ CHILDREN X-MSG-EXT UNSELECT OBJECTID
Y1 OK CAPABILITY completed
```
**(89) How can I send plain text only messages?**
By default FairEmail sends each message both as plain text and as HTML formatted text because almost every receiver expects formatted messages these days. If you want/need to send plain text messages only, you can enable this in the advanced identity options. You might want to create a new identity for this if you want/need to select sending plain text messages on a case-by-case basis.
**(90) Why are some texts linked while not being a link?**
FairEmail will automatically link not linked web links (http and https) and not linked email addresses (mailto) for your convenience. However, texts and links are not easily distinguished, especially not with lots of [top level domains](https://en.wikipedia.org/wiki/List_of_Internet_top-level_domains) being words. This is why texts with dots are sometimes incorrectly recognized as links, which is better than not recognizing some links.
Links for the tel, geo, rtsp and xmpp protocols will be recognized too, but links for less usual or less safe protocols like telnet and ftp will not be recognized. The regex to recognize links is already *very* complex and adding more protocols will make it only slower and possibly cause errors.
Note that original messages are shown exactly as they are, which means also that links are not automatically added.
**~~(91) Can you add periodical synchronization to save battery power?~~**
~~Synchronizing messages is an expensive proces because the local and remote messages need to be compared,~~ ~~so periodically synchronizing messages will not result in saving battery power, more likely the contrary.~~
~~See [this FAQ](#user-content-faq39) about optimizing battery usage.~~
**(92) Can you add spam filtering, verification of the DKIM signature and SPF authorization?**
Spam filtering, verification of the [DKIM](https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail) signature and [SPF](https://en.wikipedia.org/wiki/Sender_Policy_Framework) authorization is a task of email servers, not of an email client. I server hanno generalmente più memoria e potenza di calcolo, quindi sono molto più adatti a quest'attività piuttosto che ai dispositivi alimentati a batteria. Also, you'll want spam filtered for all your email clients, possibly including web email, not just one email client. Moreover, email servers have access to information, like the IP address, etc of the connecting server, which an email client has no access to.
Spam filtering based on message headers might have been feasible, but unfortunately this technique is [patented by Microsoft](https://patents.google.com/patent/US7543076).
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#user-content-faq71) too. Blocking the sender will create a filter rule to automatically move future messages of the same sender into the spam folder.
Note that you should not delete spam messages, also not from the spam folder, because the email server uses the messages in the spam folder to "learn" what spam messages are.
If you receive a lot of spam messages in your inbox, the best you can do is to contact the email provider to ask if spam filtering can be improved.
Also, FairEmail can show a small red warning flag when DKIM, SPF or [DMARC](https://en.wikipedia.org/wiki/DMARC) authentication failed on the receiving server. You can enable/disable [authentication verification](https://en.wikipedia.org/wiki/Email_authentication) in the display settings.
FairEmail can show a warning flag too if the domain name of the (reply) email address of the sender does not define an MX record pointing to an email server. This can be enabled in the receive settings. Be aware that this will slow down synchronization of messages significantly.
If legitimate messages are failing authentication, you should notify the sender because this will result in a high risk of messages ending up in the spam folder. Moreover, without proper authentication there is a risk the sender will be impersonated. The sender might use [this tool](https://www.mail-tester.com/) to check authentication and other things.
**(93) Can you allow installation/data storage on external storage media (sdcard)?**
FairEmail uses services and alarms, provides widgets and listens for the boot completed event to be started on device start, so it is not possible to store the app on external storage media, like an sdcard. See also [here](https://developer.android.com/guide/topics/data/install-location).
Messages, attachments, etc stored on external storage media, like an sdcard, can be accessed by other apps and is therefore not safe. See [here](https://developer.android.com/training/data-storage) for the details.
When needed you can save (raw) messages via the three-dots menu just above the message text and save attachments by tapping on the floppy icon.
If you need to save on storage space, you can limit the number of days messages are being synchronized and kept for. You can change these settings by long pressing a folder in the folder list and selecting *Edit properties*.
**(94) What does the red/orange stripe at the end of the header mean?**
The red/orange stripe at the left side of the header means that the DKIM, SPF or DMARC authentication failed. See also [this FAQ](#user-content-faq92).
**(95) Why are not all apps shown when selecting an attachment or image?**
For privacy and security reasons FairEmail does not have permissions to directly access files, instead the Storage Access Framework, available and recommended since Android 4.4 KitKat (released in 2013), is used to select files.
If an app is listed depends on if the app implements a [document provider](https://developer.android.com/guide/topics/providers/document-provider). If the app is not listed, you might need to ask the developer of the app to add support for the Storage Access Framework.
Android Q will make it harder and maybe even impossible to directly access files, see [here](https://developer.android.com/preview/privacy/scoped-storage) and [here](https://www.xda-developers.com/android-q-storage-access-framework-scoped-storage/) for more details.
**(96) Where can I find the IMAP and SMTP settings?**
The IMAP settings are part of the (custom) account settings and the SMTP settings are part of the identity settings.
**(97) What is 'cleanup' ?**
About each four hours FairEmail runs a cleanup job that:
* Removes old message texts
* Removes old attachment files
* Removes old image files
* Removes old local contacts
* Removes old log entries
Note that the cleanup job will only run when the synchronize service is active.
**(98) Why can I still pick contacts after revoking contacts permissions?**
After revoking contacts permissions Android does not allow FairEmail access to your contacts anymore. However, picking contacts is delegated to and done by Android and not by FairEmail, so this will still be possible without contacts permissions.
**(99) Can you add a rich text or markdown editor?**
FairEmail provides common text formatting (bold, italic, underline, text size and color) via a toolbar that appears after selecting some text.
A [Rich text](https://en.wikipedia.org/wiki/Formatted_text) or [Markdown](https://en.wikipedia.org/wiki/Markdown) editor would not be used by many people on a small mobile device and, more important, Android doesn't support a rich text editor and most rich text editor open source projects are abandoned. See [here](https://forum.xda-developers.com/showpost.php?p=79061829&postcount=4919) for some more details about this.
**(100) How can I synchronize Gmail categories?**
You can synchronize Gmail categories by creating filters to label categorized messages:
* Create a new filter via Gmail > Settings (wheel) > Filters and Blocked Addresses > Create a new filter
* Enter a category search (see below) in the *Has the words* field and click *Create filter*
* Check *Apply the label* and select a label and click *Create filter*
Possible categories:
```
categoria: social
categoria: aggiornamenti
categoria: forum
categoria: promozioni
```
Unfortunately, this is not possible for snoozed messages folder.
You can use *Force sync* in the three-dots menu of the unified inbox to let FairEmail synchronize the folder list again and you can long press the folders to enable synchronization.
**(101) What does the blue/orange dot at the bottom of the conversations mean?**
The dot shows the relative position of the conversation in the message list. The dot will be show orange when the conversation is the first or last in the message list, else it will be blue. The dot is meant as an aid when swiping left/right to go to the previous/next conversation.
The dot is disabled by default and can be enabled with the display settings *Show relative conversation position with a dot*.
**(102) How can I enable auto rotation of images?**
Images will automatically be rotated when automatic resizing of images is enabled in the settings (enabled by default). However, automatic rotating depends on the [Exif](https://en.wikipedia.org/wiki/Exif) information to be present and to be correct, which is not always the case. Particularly not when taking a photo with a camara app from FairEmail.
Note that only [JPEG](https://en.wikipedia.org/wiki/JPEG) and [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics) images can contain Exif information.
**(104) What do I need to know about error reporting?**
* Error reports will help improve FairEmail
* Error reporting is optional and opt-in
* Error reporting can be enabled/disabled in the settings, section miscellaneous
* Error reports will automatically be sent anonymously to [Bugsnag](https://www.bugsnag.com/)
* Bugsnag for Android is [open source](https://github.com/bugsnag/bugsnag-android)
* See [here](https://docs.bugsnag.com/platforms/android/automatically-captured-data/) about what data will be sent in case of errors
* See [here](https://docs.bugsnag.com/legal/privacy-policy/) for the privacy policy of Bugsnag
* Error reports will be sent to *sessions.bugsnag.com:443* and *notify.bugsnag.com:443*
**(105) How does the roam-like-at-home option work?**
FairEmail will check if the country code of the SIM card and the country code of the network are in the [EU roam-like-at-home countries](https://en.wikipedia.org/wiki/European_Union_roaming_regulations#Territorial_extent) and assumes no roaming if the country codes are equal and the advanced roam-like-at-home option is enabled.
So, you don't have to disable this option if you don't have an EU SIM or are not connected to an EU network.
**(106) Which launchers can show a badge count with the number of unread messages?**
Please [see here](https://github.com/leolin310148/ShortcutBadger#supported-launchers) for a list of launchers which can show the number of unread messages.
Note that the notification setting *Show launcher icon with number of new messages* needs to be enabled (default enabled).
Only *new* unread messages in folders set to show new message notifications will be counted, so messages marked unread again and messages in folders set to not show new message notification will not be counted.
Depending on what you want, the notification settings *Let the number of new messages match the number of notifications* needs to be enabled or disabled.
This feature depends on support of your launcher. FairEmail merely 'broadcasts' the number of unread messages using the ShortcutBadger library. If it doesn't work, this cannot be fixed by changes in FairEmail.
Some launchers display '1' for [the monitoring notification](#user-content-faq2), despite FairEmail explicitly requesting not to show a badge for this notification. This could be caused by a bug in the launcher app or in your Android version. Please double check if the notification dot is disabled for the receive (service) notification channel. You can go to the right notification channel settings via the notification settings of FairEmail. This might not be obvious, but you can tap on the channel name for more settings.
Nota che Tesla Unread [non è più supportata](https://forum.xda-developers.com/android/general/bad-news-tesla-unread-devoloper-t3920415).
FairEmail does send a new message count intent as well:
```
eu.faircode.email.NEW_MESSAGE_COUNT
```
The number of new, unread messages will be in an integer "*count*" parameter.
**(107) How do I use colored stars?**
You can set a colored star via the *more* message menu, via multiple selection (started by long pressing a message), by long pressing a star in a conversation or automatically by using [rules](#user-content-faq71).
You need to know that colored stars are not supported by the IMAP protocol and can therefore not be synchronized to an email server. This means that colored stars will not be visible in other email clients and will be lost on downloading messages again. However, the stars (without color) will be synchronized and will be visible in other email clients, when supported.
Some email clients use IMAP keywords for colors. However, not all servers support IMAP keywords and besides that there are no standard keywords for colors.
**~~(108) Can you add permanently delete messages from any folder?~~**
~~When you delete messages from a folder the messages will be moved to the trash folder, so you have a chance to restore the messages.~~ ~~You can permanently delete messages from the trash folder.~~ ~~Permanently delete messages from other folders would defeat the purpose of the trash folder, so this will not be added.~~
**~~(109) Why is 'select account' available in official versions only?~~**
~~Using *select account* to select and authorize Google accounts require special permission from Google for security and privacy reasons.~~ ~~This special permission can only be acquired for apps a developer manages and is responsible for.~~ ~~Third party builds, like the F-Droid builds, are managed by third parties and are the responsibility of these third parties.~~ ~~So, only these third parties can acquire the required permission from Google.~~ ~~Since these third parties do not actually support FairEmail, they are most likely not going to request the required permission.~~
~~You can solve this in two ways:~~
* ~~Switch to the official version of FairEmail, see [here](https://github.com/M66B/FairEmail/blob/master/README.md#downloads) for the options~~
* ~~Use app specific passwords, see [this FAQ](#user-content-faq6)~~
~~Using *select account* in third party builds is not possible in recent versions anymore.~~ ~~In older versions this was possible, but it will now result in the error *UNREGISTERED_ON_API_CONSOLE*.~~
**(110) Why are (some) messages empty and/or attachments corrupt?**
Empty messages and/or corrupt attachments are probably being caused by a bug in the server software. Older Microsoft Exchange software is known to cause this problem. Mostly you can workaround this by disabling *Partial fetch* in the advanced account settings:
Setup > Step 1 > Manage > Tap account > Tap advanced > Partial fetch > uncheck
After disabling this setting, you can use the message 'more' (three dots) menu to 'resync' empty messages. Alternatively, you can *Delete local messages* by long pressing the folder(s) in the folder list and synchronize all messages again.
Disabling *Partial fetch* will result in more memory usage.
**(111) Is OAuth supported?**
OAuth for Gmail is supported via the quick setup wizard. The Android account manager will be used to fetch and refresh OAuth tokens for selected on-device accounts. OAuth for non on-device accounts is not supported because Google requires a [yearly security audit](https://support.google.com/cloud/answer/9110914) ($15,000 to $75,000) for this. You can read more about this [here](https://www.theregister.com/2019/02/11/google_gmail_developer/).
OAuth for Yandex and Yahoo is supported via the quick setup wizard.
OAuth for Office 365 accounts is supported, but Microsoft does not offer OAuth for Outlook, Live and Hotmail accounts (yet?).
**(112) Which email provider do you recommend?**
FairEmail is an email client only, so you need to bring your own email address.
There are plenty of email providers to choose from. Which email provider is best for you depends on your wishes/requirements. Please see the websites of [Restore privacy](https://restoreprivacy.com/secure-email/) or [Privacy Tools](https://www.privacytools.io/providers/email/) for a list of privacy oriented email providers with advantages and disadvantages.
Some providers, like ProtonMail, Tutanota, use proprietary email protocols, which make it impossible to use third party email apps. Please see [this FAQ](#user-content-faq129) for more information.
Using your own (custom) domain name, which is supported by most email providers, will make it easier to switch to another email provider.
**(113) How does biometric authentication work?**
If your device has a biometric sensor, for example a fingerprint sensor, you can enable/disable biometric authentication in the navigation (hamburger) menu of the setup screen. When enabled FairEmail will require biometric authentication after a period of inactivity or after the screen has been turned off while FairEmail was running. Activity is navigation within FairEmail, for example opening a conversation thread. The inactivity period duration can be configured in the miscellaneous settings. When biometric authentication is enabled new message notifications will not show any content and FairEmail won't be visible on the Android recents screen.
Biometric authentication is meant to prevent others from seeing your messages only. FairEmail relies on device encryption for data encryption, see also [this FAQ](#user-content-faq37).
Biometric authentication is a pro feature.
**(114) Can you add an import for the settings of other email apps?**
The format of the settings files of most other email apps is not documented, so this is difficult. Sometimes it is possible to reverse engineer the format, but as soon as the settings format changes things will break. Also, settings are often incompatible. For example, FairEmail has unlike most other email apps settings for the number of days to synchronize messages for and for the number of days to keep messages for, mainly to save on battery usage. Moreover, setting up an account/identity with the quick setup is simple, so it is not really worth the effort.
**(115) Can you add email address chips?**
Email address [chips](https://material.io/design/components/chips.html) look nice, but cannot be edited, which is quite inconvenient when you made a typo in an email address.
Note that FairEmail will select the address only when long pressing an address, which makes it easy to delete an address.
Chips are not suitable for showing in a list and since the message header in a list should look similar to the message header of the message view it is not an option to use chips for viewing messages.
Reverted [commit](https://github.com/M66B/FairEmail/commit/2c80c25b8aa75af2287f471b882ec87d5a5a5015).
**~~(116) How can I show images in messages from trusted senders by default?~~**
~~You can show images in messages from trusted senders by default by enabled the display setting *Automatically show images for known contacts*.~~
~~Contacts in the Android contacts list are considered to be known and trusted,~~ ~~unless the contact is in the group / has the label '*Untrusted*' (case insensitive).~~
**(117) Can you help me restore my purchase?**
Google manages all purchases, so as a developer I have little control over purchases. So, basically the only thing I can do, is give some advice:
* Make sure you have an active, working internet connection
* Make sure you are logged in with the right Google account and that there is nothing wrong with your Google account
* Make sure you installed FairEmail via the right Google account if you configured multiple Google accounts on your device
* Make sure the Play store app is up to date, please [see here](https://support.google.com/googleplay/answer/1050566?hl=en)
* Open the Play store app and wait at least a minute to give it time to synchronize with the Google servers
* Open FairEmail and navigate to the pro features screen to let FairEmail check the purchases; sometimes it help to tap the *buy* button
You can also try to clear the cache of the Play store app via the Android apps settings. Restarting the device might be necessary to let the Play store recognize the purchase correctly.
Note that:
* If you get *ITEM_ALREADY_OWNED*, the Play store app probably needs to be updated, please [see here](https://support.google.com/googleplay/answer/1050566?hl=en)
* Purchases are stored in the Google cloud and cannot get lost
* There is no time limit on purchases, so they cannot expire
* Google does not expose details (name, e-mail, etc) about buyers to developers
* An app like FairEmail cannot select which Google account to use
* It may take a while until the Play store app has synchronized a purchase to another device
* Play Store purchases cannot be used without the Play Store, which is also not allowed by Play Store rules
If you cannot solve the problem with the purchase, you will have to contact Google about it.
**(118) What does 'Remove tracking parameters' exactly?**
Checking *Remove tracking parameters* will remove all [UTM parameters](https://en.wikipedia.org/wiki/UTM_parameters) from a link.
**~~(119) Can you add colors to the unified inbox widget?~~**
~~The widget is designed to look good on most home/launcher screens by making it monochrome and by using a half transparent background.~~ ~~This way the widget will nicely blend in, while still being properly readable.~~
~~Adding colors will cause problems with some backgrounds and will cause readability problems, which is why this won't be added.~~
Due to Android limitations it is not possible to dynamically set the opacity of the background and to have rounded corners at the same time.
**(120) Why are new message notifications not removed on opening the app?**
New message notifications will be removed on swiping notifications away or on marking the associated messages read. Opening the app will not remove new message notifications. This gives you a choice to leave new message notifications as a reminder that there are still unread messages.
On Android 7 Nougat and later new message notifications will be [grouped](https://developer.android.com/training/notify-user/group). Tapping on the summary notification will open the unified inbox. The summary notification can be expanded to view individual new message notifications. Tapping on an individual new message notification will open the conversation the message it is part of. See [this FAQ](#user-content-faq70) about when messages in a conversation will be auto expanded and marked read.
**(121) How are messages grouped into a conversation?**
By default FairEmail groups messages in conversations. This can be turned of in the display settings.
FairEmail groups messages based on the standard *Message-ID*, *In-Reply-To* and *References* headers. FairEmail does not group on other criteria, like the subject, because this could result in grouping unrelated messages and would be at the expense of increased battery usage.
**~~(122) Why is the recipient name/email address show with a warning color?~~**
~~The recipient name and/or email address in the addresses section will be shown in a warning color~~ ~~when the sender domain name and the domain name of the *to* address do not match.~~ ~~Mostly this indicates that the message was received *via* an account with another email address.~~
**(123) What will happen when FairEmail cannot connect to an email server?**
If FairEmail cannot connect to an email server to synchronize messages, for example if the internet connection is bad or a firewall or a VPN is blocking the connection, FairEmail will retry two times after waiting 4 and 8 seconds while keeping the device awake (=use battery power). If this fails, FairEmail will schedule an alarm to retry after 15, 30 and eventually every 60 minutes and let the device sleep (=no battery usage).
Note that [Android doze mode](https://developer.android.com/training/monitoring-device-state/doze-standby) does not allow to wake the device earlier than after 15 minutes.
*Force sync* in the three-dots menu of the unified inbox can be used to let FairEmail attempt to reconnect without waiting.
Sending messages will be retried on connectivity changes only (reconnecting to the same network or connecting to another network) to prevent the email server from blocking the connection permanently. You can pull down the outbox to retry manually.
Note that sending will not be retried in case of authentication problems and when the server rejected the message. In this case you can pull down the outbox to try again.
**(124) Why do I get 'Message too large or too complex to display'?**
The message *Message too large or too complex to display* will be shown if there are more than 100,000 characters or more than 500 links in a message. Reformatting and displaying such messages will take too long. You can try to use the original message view, powered by the browser, instead.
**(125) What are the current experimental features?**
*Message classification (version 1.1438+)*
Sei pregato di vedere [questa FAQ](#user-content-faq163) per i dettagli.
Essendo una funzionalità sperimentale, il mio consiglio è di iniziare con una sola cartella.
**(126) Le anteprime dei messaggi possono essere inviate al mio indossabile?**
FairEmail recupera un messaggio in due passaggi:
1. Fetch message headers
1. Fetch message text and attachments
Direttamente dopo il primo passaggio saranno notificati i nuovi messaggi. Tuttavia, solo dopo il secondo il testo del messaggio sarà disponibile. FairEmail aggiorna le notifiche esistenti con un'anteprima del testo del messaggio, ma sfortunatamente le notifiche dell'indossabile non possono essere aggiornate.
Non essendoci garanzia che il testo di un messaggio sia sempre recuperato direttamente dopo l'intestazione del messaggio, non si può garantire che la notifica di un nuovo messaggio con un testo di anteprima sia sempre inviata a un indossabile.
Se pensi che sia abbastanza, puoi abilitare l'opzione di notifica *Invia solo le notifiche con un'anteprima di messaggio agli indossabile* e se non funziona, puoi provare ad abilitare l'opzione di notifica *Mostra solo le notifiche con un testo di anteprima*. Nota che questo si applica anche agli indossabili che non mostrano un testo di anteprima, anche quando l'app Android Wear dice che la notifica è stata inviata (collegata).
Se vuoi aver inviato il testo completo del messaggio al tuo indossabile, puoi abilitare l'opzione di notifica *Anteprima del testo completo*. Nota che alcuni indossabili sono noti per esser crashati con quest'opzione abilitata.
Se usi un indossabile di Samsung con l'app Galaxy Wearable (Samsung Gear), potresti dover abilitare le notifiche per FairEmail impostando *Notifiche*, *App installate in futuro* è disattivata in quest'app.
**(127) Come posso correggere 'Argomenti HELO sintatticamente non validi?**
L'errore *... Argomenti HELO sintatticamente non validi ...* significa che il server SMTP ha rifiutato l'indirizzo IP locale o il nome dell'host. Potresti correggere quest'errore abilitando o disabilitando l'opzione di identità avanzata *Usa l'indirizzo IP locale invece del nome dell'host*.
**(128) Come posso ripristinare le domande fatte, ad esempio per mostrare immagini=**
Puoi ripristinare le domande fatte tramite il menu di panoramica a tre puntini nelle impostazioni varie.
**(129) ProtonMail e Tutanota sono supportate?**
ProtonMail usa un protocollo email proprietario e [non supporta direttamente IMAP](https://protonmail.com/support/knowledge-base/imap-smtp-and-pop3-setup/), quindi non puoi usare FairEmail per accedere ProtonMail.
Tutanota usa un protocollo email proprietario e [non supporta IMAP](https://tutanota.com/faq/#imap), quindi non puoi usare FairEmail per accedere a Tutanota.
**(130) Cosa significa il messaggio di errore ...?**
Una serie di righe con testi arancioni o rossi con informazioni tecniche significa che la modalità di debug è stata abilitata nelle impostazioni miste.
L'avviso *Nessun server trovato a ...* significa che non è stato indicato alcun server email al nome di dominio indicato. Rispondere al messaggio potrebbe non essere possibile e potrebbe risultare in un errore. Questo potrebbe indicare un indirizzo email falsificato e/o spam.
L'errore *... ParseException ...* significa che c'è un problema con un messaggio ricevuto, probabilmente causato da un bug nel software di invio. FairEmail lo risolverà nella maggior parte dei casi, quindi questo messaggio è prevalentemente considerabile come un avviso invece che un errore.
L'errore *...SendFailedException...* significa che si è verificato un problema inviando un messaggio. L'errore includerà quasi sempre un motivo. Motivi comuni sono che il messaggio era troppo grande o che uno o più indirizzi del destinatario non erano validi.
L'avviso *Messaggio troppo grande per la memoria disponibile* significa che il messaggio era più grande di 10 MiB. Anche se il tuo dispositivo ha molto spazio di archiviazione, Android fornisce memoria operativa limitata alle app, il che limita la dimensione dei messaggi gestibili.
Sei pregato di vedere [qui](#user-content-faq22) per altri messaggi di errore nella posta in uscita.
**(131) Puoi modificare la direzione per scorrere al messaggio precedente/successivo?**
Se leggi da sinistra a destra, scorrere a sinistra mostrerà il messaggio successivo. Allo stesso modo, se leggi da destra a sinistra, scorrere a destra mostrerà quello successivo.
Questo comportamento mi sembra molto naturale, anche perché somiglia a voltare le pagine.
Ad ogni modo, esiste un'impostazione di comportamento per invertire la direzione di scorrimento.
**(132) Perché le notifiche dei nuovi messaggi sono silenziose?**
Le notifiche sono silenziose di default su alcune versioni di MIUI. Sei pregato di vedere [qui](http://en.miui.com/thread-3930694-1-1.html) come puoi risolverlo.
Esiste un bug in alcune versioni di Android che causa che [setOnlyAlertOnce](https://developer.android.com/reference/android/app/Notification.Builder#setOnlyAlertOnce(boolean)) silenzi le notifiche. Poiché FairEmail mostra le notifiche dei nuovi messaggi subito dopo averne recuperato le intestazioni e che FairEmail deve aggiornare le notifiche dei nuovi messaggi dopo il successivo recupero del testo del messaggio, questo non è correggibile o risolvibile da FairEmail.
Android potrebbe limitare il suono di notifica, il che può causare il silenziamento di alcune notifiche dei messaggi.
**(133) Perché ActiveSync non è supportato?**
Il protocollo ActiveSync di Microsoft Exchange [è brevettato](https://en.wikipedia.org/wiki/Exchange_ActiveSync#Licensing) a può dunque non essere supportato. Per questo motivo non troverai molti altri client email, se presenti, che supportano ActiveSync.
Il protocollo dei Servizi Web di Microsoft Exchange [è in fase di eliminazione](https://techcommunity.microsoft.com/t5/Exchange-Team-Blog/Upcoming-changes-to-Exchange-Web-Services-EWS-API-for-Office-365/ba-p/608055).
Nota che la descrizione di FairEmail inizia con l'osservazione che i protocolli non standard, come i Servizi Web di Microsoft Exchange e ActiveSync di Microsoft non sono supportati.
**(134) Puoi aggiungere l'eliminazione dei messaggi locali?**
*POP3*
Nelle impostazioni del profilo (Configurazione, passaggio 1, Gestione, tocca profilo) puoi abilitare *Lascia i messaggi eliminati sul server*.
*IMAP*
Poiché il protocollo IMAP è destinato alla sincronizzazione in due modi, eliminare un messaggio dal dispositivo risulterebbe nel recupero del messaggio alla nuova sincronizzazione.
Tuttavia, FairEmail supporta i messaggi nascosti, tramite il menu a tre puntini nella barra di azione proprio sopra il testo del messaggio o selezionando messaggi multipli nell'elenco dei messaggi. Fondamentalmente questo equivale a "lascia sul server" del protocollo POP3 con il vantaggio di poter mostrare ancora i messaggi quando necessario.
Nota che è possibile impostare l'azione di scorrimento da sinistra a destra per nascondere un messaggio.
**(135) Perché i messaggi cestinati e le bozze sono mostrate nelle conversazioni?**
I messaggi individuali saranno raramente cestinati e prevalentemente si verifica per incidente. Mostrare i messaggi cestinati nelle conversazioni rende più facile ritrovarli.
Puoi eliminare un messaggio permanentemente usando *elimina* nel menu a tre puntini del messaggio, che rimuoverà il messaggio dalla conversazione. Nota che è irreversibile.
Similmente, le bozze sono mostrate nelle conversazioni per ritrovarle nel contesto a cui appartengono. Leggere i messaggi ricevuti è facile prima di continuare a scrivere la bozza in seguito.
**(136) Come posso eliminare un profilo/identità/cartella?**
L'eliminazione di un profilo/identità/cartella è un po' nascosta per prevenire gli incidenti.
* Account: Setup > Step 1 > Manage > Tap account
* Identity: Setup > Step 2 > Manage > Tap identity
* Folder: Long press the folder in the folder list > Edit properties
Nel menu di trabocco a tre puntini in alto a destra esiste un elemento per eliminare il profilo/identità/cartella.
**(137) Come posso ripristinare 'Non chiedermelo più'?**
Puoi ripristinare tutte le domande impostate per non esser chieste più nelle impostazioni miste.
**(138) Puoi aggiungere il calendario, la gestione dei contatti, la sincronizzazione?**
Il calendario e la gestione dei contatti sono realizzabili da un'app separata specializzata. Nota che FairEmail è un'app email specializzata, non una suite da ufficio.
Inoltre, preferisco fare alcune cose molto bene, invece che molte solo a metà. Inoltre, dal punto di vista della sicurezza, non è una buona idea garantire molti permessi a un'app singola.
Si consiglia di usare l'eccellente app open source [DAVx⁵](https://f-droid.org/packages/at.bitfire.davdroid/) per sincronizzare/gestire i tuoi calendari/contatti.
Gran parte dei provider supportano l'esportazione dei tuoi contatti. Sei pregato di [vedere qui](https://support.google.com/contacts/answer/1069522) come puoi importare i contatti se la sincronizzazione è impossibile.
Nota che FairEmail supporta la risposta agli inviti del calendario (una funzionalità pro) e l'aggiunta di inviti del calendario al tuo calendario personale.
**(139) Come correggo 'Utente autenticato ma non connesso'?**
Difatti questo errore specifico di Microsoft Exchange è un messaggio di errore scorretto causato da un bug nel vecchio software del server di Exchange.
L'errore *Utente autenticato ma non connesso* potrebbe verificarsi se:
* Push messages are enabled for too many folders: see [this FAQ](#user-content-faq23) for more information and a workaround
* The account password was changed: changing it in FairEmail too should fix the problem
* An alias email address is being used as username instead of the primary email address
* An incorrect login scheme is being used for a shared mailbox: the right scheme is *username@domain\SharedMailboxAlias*
Gli alias della casella di posta elettronica condivisa saranno prevalentemente gli indirizzi di posta elettronica del profilo condiviso, come questo:
```
you@example.com\shared@example.com
```
Nota che dovrebbe essere un backslash e non uno slash.
**(140) Perché il testo del messaggio contiene caratteri strani?**
La visualizzazione di caratteri strani è quasi sempre causata dalla specificazione o meno di una codifica non valida del carattere inviata dal software. FairEmail presumerà che [ISO 8859-1](https://en.wikipedia.org/wiki/ISO/IEC_8859-1) quando nessun carattere è impostato o quando è stato specificato [US-ASCII](https://en.wikipedia.org/wiki/ASCII). Oltre al fatto che non c'è modo di determinare affidabilmente la crittografia corretta dei caratteri automaticamente, quindi non è correggibile da FairEmail. L'azione giusta è quella di lamentarsi con il mittente.
**(141) Come posso correggere 'Una cartella di bozze è necessaria per inviare i messaggi'?**
Per memorizzare i messaggi di bozza è necessaria una cartella delle bozze. In molti casi FairEmail selezionerà automaticamente le cartelle di bozze all'aggiunta di un profilo basato [sugli attributi](https://www.iana.org/assignments/imap-mailbox-name-attributes/imap-mailbox-name-attributes.xhtml) inviati dal server email. Tuttavia, alcuni server email non sono propriamente configurati e non inviano tali attributi. In questo caso FairEmail prova a identificare la cartella delle bozze per nome, ma questo potrebbe fallire se la cartella delle bozze ha un nome insolito o non è presente affatto.
Puoi risolvere questo problema selezionando manualmente la cartella delle bozze nelle impostazioni del profilo (Configurazione, passaggio 1, tocca profilo, in basso). Se non esiste alcuna cartella delle bozze, puoi crearne una toccando sul pulsante '+' nell'elenco delle cartelle del profilo (tocca il nome del profilo nel menu di navigazione).
Alcuni provider, come Gmail, consentono di abilitare/disabilitare IMAP per le cartelle singole. Quindi, se una cartella è invisibile, potresti dover abilitare l'IMAP per essa.
Collegamento rapido per Gmail: [https://mail.google.com/mail/u/0/#settings/labels](https://mail.google.com/mail/u/0/#settings/labels)
**(142) Come posso memorizzare i messaggi inviati nella posta in arrivo?**
Generalmente, non è una buona idea memorizzare i messaggi inviati nella posta in arrivo perché difficile da annullare e potrebbe essere non compatibile con altri client di posta elettronica.
Detto ciò, FairEmail può gestire propriamente i messaggi inviati nella posta di arrivo. FairEmail contrassegnerà i messaggi in uscita con l'icona di quelli inviati, per esempio.
La soluzione migliore sarebbe abilitare la visualizzazione della cartella inviati nella posta in arrivo unica premendo a lungo sulla cartella inviati nell'elenco delle cartelle e abilitando *Mostra nella posta in arrivo unificata*. Così tutti i messaggi possono rimanere a dove appartengono, consentendo di vedere sia i messaggi in entrata che in uscita in un posto.
Se non è possibile, puoi [creare una regola](#user-content-faq71) per spostare automaticamente i messaggi inviati in posta in arrivo o impostare un indirizzo CC/BCC predefinito nelle impostazioni di identità avanzata per inviarti una copia.
**~~(143) Puoi aggiungere una cartella del cestino per i profili POP3?~~**
[POP3](https://en.wikipedia.org/wiki/Post_Office_Protocol) è un protocollo molto limitato. Fondamentalmente solo i messaggi sono scaricabili ed eliminabili dalla posta in arrivo. Non si può nemmeno segnare un messaggio come letto.
Poiché POP3 non consente alcun accesso al cestino, non c'è modo di ripristinare i messaggi cestinati.
Nota che puoi nascondere i messaggi e cercare quelli nascosti, similmente alla cartella locale del cestino, senza suggerire che i messaggi cestinati siano ripristinati, mentre non è realmente possibile.
La versione 1.1082 ha aggiunto una cartella locale del cestino. Nota che cestinare un messaggio lo rimuoverà permanentemente dal server e che i messaggi cestinati non sono più ripristinabili al server.
**(144) Come posso registrare le note vocali?**
Per registrare le note vocali puoi premere quest'icona nella barra di azione in basso del compositore di messaggi:
Questo richiede un'app di registrazione audio compatibile installata. In particolare [questo intento comune](https://developer.android.com/reference/android/provider/MediaStore.Audio.Media.html#RECORD_SOUND_ACTION) deve essere supportato.
Per esempio [questo registratore audio](https://f-droid.org/app/com.github.axet.audiorecorder) è compatibile.
Le note vocali saranno allegate automaticamente.
**(145) Come posso impostare un suono di notifica per un profilo, una cartella o un mittente?**
Profilo:
* Enable *Separate notifications* in the advanced account settings (Setup, step 1, Manage, tap account, tap Advanced)
* Long press the account in the account list (Setup, step 1, Manage) and select *Edit notification channel* to change the notification sound
Cartella:
* Long press the folder in the folder list and select *Create notification channel*
* Long press the folder in the folder list and select *Edit notification channel* to change the notification sound
Mittente:
* Open a message from the sender and expand it
* Expand the addresses section by tapping on the down arrow
* Tap on the bell icon to create or edit a notification channel and to change the notification sound
L'ordine di precedenza è: suono del mittente, suono della cartella, suono del profilo e suono predefinito.
Impostare un suono di notifica per un profilo, una cartella o un mittente richiede Android 8 Oreo o successiva ed è una funzionalità pro.
**(146) Come posso correggere gli orari del messaggio non corretti?**
Poiché la data/ora è opzionale e manipolabile dal mittente, FairEmail usa la data/ora di ricezione del server di default.
A volte la data/ora di ricezione del server non è corretta, principalmente perché i messaggi sono stati importati scorrettamente da un altro server e talvolta a causa di un bug nel server dell'email.
In questi rari casi, è possibile far usare a FairEmail la data o l'ora dall'intestazione *Data* (orario di invio) o Ricevuto come soluzione. Questo si può modificare nelle impostazioni avanzate del profilo: Configurazione, passaggio 1, Gestione, tocca profilo, tocca Avanzate.
Questo non cambierà l'ora dei messaggi già sincronizzati. Per risolverlo, premi a lungo sulle cartelle nell'elenco della cartella e seleziona *Elimina i messaggi locali* e *Sincronizza ora*.
**(147) Cosa dovrei sapere sulle versioni di terze parti?**
Potresti venire qui perché stai usando una build di terze parti di FairEmail.
Esiste **il supporto solo** sull'ultima versione del Play Store, l'ultima release di GitHub e la build di F-Droid, ma **solo se** il numero della versione della build di F-Droid è la stessa del numero di versione dell'ultima release di GitHub.
F-Droid si costruisce irregolarmente, il che può essere problematico quando c'è un aggiornamento importante. Dunque ti si consiglia di passare alla release di GitHub.
La versione di F-Droid è costruito dallo stesso codice sorgente, ma firmato differentemente. Questo significa che tutte le funzionalità sono disponibili anche nella versione di F-Droid, eccetto per usare la procedura guidata rapida di Gmail perché Google ha approvato (e consente) solo una firma dell'app. Per tutti gli altri provider email, l'accesso OAuth è disponibile solo nelle versioni del Play Store e le release di GitHub, così come i provider email permettono solo l'uso di OAuth per le build ufficiali.
Nota che dovrai disinstallare la build di F-Droid prima di poter installare una release di GitHub perché Android rifiuta di installare la stessa app con una firma differente per motivi di sicurezza.
Nota che la versione di GitHub controllerà automaticamente gli aggiornamenti. Quando desiderato, questo è disattivabile nelle impostazioni miste.
Sei pregato di [vedere qui](https://github.com/M66B/FairEmail/blob/master/README.md#user-content-downloads) per tutte le opzioni di download.
Se hai un problema con la build di F-Droid, sei pregato di controllare che ci sia una versione più nuova di GitHub prima.
**(148) Come posso usare un profilo di Apple iCloud?**
Esiste un profilo integrato per Apple iCloud, ma se necessario puoi trovare le impostazioni giuste [qui](https://support.apple.com/en-us/HT202304).
Quando usi l'autenticazione a due fattori potresti dover usare una [password specifica dell'app](https://support.apple.com/en-us/HT204397).
**(149) Come funziona il widget di conteggio dei messaggi non letti?**
Il widget di conteggio dei messaggi non letti mostra il numero di messaggi non letti per tutti i profilo o per un profilo selezionato, ma solo per le cartelle per cui sono abilitate le notifiche del nuovo messaggio.
Toccare sulla notifica sincronizzerà tutte le cartelle per cui è abilitata la sincronizzazione e aprirà:
* 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) Puoi aggiungere l'annullamento degli inviti del calendario?**
Annullare gli inviti del calendario (rimuovere gli eventi del calendario) richiede permessi di scrittura del calendario, che risulteranno nella garanzia effettiva del permesso per leggere e scrivere *tutti* gli eventi del calendario di *tutti* i calendari.
Dato lo scopo di FairEmail, la privacy e la sicurezza, e dato che è facile rimuovere manualmente l'evento di un calendario, non è una buona idea richiedere questo permesso solo per questo motivo.
Inserire nuovi eventi del calendario può esser fatto senza permessi con [intenti](https://developer.android.com/guide/topics/providers/calendar-provider.html#intents) speciali. Sfortunatamente, non esiste alcun intento per eliminare gli eventi esistenti del calendario.
**(151) Puoi aggiungere il backup/ripristino dei messaggi?**
Un client email è inteso per leggere e scrivere i messaggi, non per il backup e ripristino dei messaggi. Nota che rompere o perdere il tuo dispositivo, significa perdere i tuoi messaggi!
Invece, il provider email/server è responsabile per i backup.
Se vuoi creare tu stesso un backup, potresti usare uno strumento come [imapsync](https://imapsync.lamiral.info/).
Se vuoi importare un file mbox a un profilo email esistente, puoi usare Thunderbird su un computer desktop e l'addon [ImportExportTools](https://addons.thunderbird.net/nl/thunderbird/addon/importexporttools/).
**(152) Come posso inserire un gruppo di contatto?**
Puoi inserire gli indirizzi email di tutti i contatti in un gruppo di contatti tramite il menu a tre puntini del compositore di messaggi.
Puoi definire i gruppi di contatti con l'app dei contatti di Android, sei pregato di vedere [qui](https://support.google.com/contacts/answer/30970) per le istruzioni.
**(153) Perché eliminare permanentemente il messaggio di Gmail non funziona?**
Potresti dover cambiare [le impostazioni IMAP di Gmail](https://mail.google.com/mail/u/0/#settings/fwdandpop) su un browser desktop per farlo funzionare:
* 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
Nota che i messaggi archiviati sono eliminabili solo spostandoli prima alla cartella del cestino.
Qualche sfondo: Gmail sembra avere una vista aggiuntiva del messaggio per IMAP, che può essere differente dalla vista dei messaggi principale.
**~~(154) Puoi aggiungere i favicon come foto di contatto?~~**
~~ Oltre il fatto che un [favicon](https://en.wikipedia.org/wiki/Favicon) potrebbe essere condiviso da molti indirizzi email con lo stesso nome del dominio~~ ~~e dunque non correlato direttamente a un indirizzo email, i favicon sono utilizzabili per monitorarti.~~
**(155) Cos'è un file winmail.dat?**
Un file *winmail.dat* è inviato da un client di Outlook configurato in modo errato. Si tratta di un formato di file specifico di Microsoft ([TNEF](https://en.wikipedia.org/wiki/Transport_Neutral_Encapsulation_Format)) contenente un messaggio e possibilmente allegati.
Puoi trovare alcune altre informazioni su questo file [qui](https://support.mozilla.org/en-US/kb/what-winmaildat-attachment).
Puoi visualizzarlo per esempio con l'app Android [Letter Opener](https://play.google.com/store/apps/details?id=app.letteropener).
**(156) Come posso configurare un profilo Office 365?**
Un profilo Office 365 può essere configurato tramite la procedura guidata rapida e selezionando *Office 365 (OAuth)>*.
Se la procedura guidata si conclude con *AUTHENTICATE failed*, IMAP e/o SMTP potrebbe essere disabilitato per il profilo. In questo caso dovresti chiedere all'amministratore di abilitare IMAP e SMTP. La procedura è documentata [qui](https://docs.microsoft.com/en-in/exchange/troubleshoot/configure-mailboxes/pop3-imap-owa-activesync-office-365).
Se hai abilitato i *predefiniti di sicurezza* nella tua organizzazione, potresti dover abilitare il protocollo SMTP AUTH. Sei pregato di [vedere qui](https://docs.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/authenticated-client-smtp-submission) come farlo.
**(157) Come posso configurare un profilo Free.fr?**
Siete pregati di [vedere qui](https://free.fr/assistance/597.html) per le istruzioni.
**SMTP è disattivato di default**, sei pregato di [vedere qui](https://free.fr/assistance/2406.html) come attivarlo.
Siete pregati di [vedere qui](http://jc.etiemble.free.fr/abc/index.php/trucs-astuces/configurer-smtp-free-fr) per una guida dettagliata.
**(158) Che fotocamera / registratore audio consigli?**
Per scattare foto e registrare audio è necessaria un'app fotocamera e una di registrazione audio. Le seguenti app sono registratori audio e fotocamere open source:
* [Open Camera](https://play.google.com/store/apps/details?id=net.sourceforge.opencamera) ([F-Droid](https://f-droid.org/en/packages/net.sourceforge.opencamera/))
* [Audio Recorder version 3.3.24+](https://play.google.com/store/apps/details?id=com.github.axet.audiorecorder) ([F-Droid](https://f-droid.org/packages/com.github.axet.audiorecorder/))
Per registrare le note vocali, etc, il registratore audio deve supportare [MediaStore.Audio.Media.RECORD_SOUND_ACTION](https://developer.android.com/reference/android/provider/MediaStore.Audio.Media#RECORD_SOUND_ACTION). Stranamente, gran parte dei registratori audio sembra non supportare quest'azione Android standard.
**(159) Cosa sono gli elenchi di protezione del monitor di Disconnect?**
Sei pregato di vedere [qui](https://disconnect.me/trackerprotection) per ulteriori informazioni sugli elenchi di protezione del monitor di Disconnect.
Dopo il download degli elenchi nelle impostazioni di privacy, gli possono opzionalmente essere usati:
* to warn about tracking links on opening links
* to recognize tracking images in messages
Le immagini di monitoraggio saranno disabilitati solo se l'opzione 'disabilita' principale corrispondente è abilitata.
Il monitoraggio delle immagini non sarà riconosciuto alla classificazione del dominio come '*Contenuto*', vedi [qui](https://disconnect.me/trackerprotection#trackers-we-dont-block) per ulteriori informazioni.
Questo comando è inviabile a FairEmail da un'app di automazione per aggiornare gli elenchi di protezione:
```
(adb shell) am startservice -a eu.faircode.email.DISCONNECT.ME
```
Aggiornare una volta a settimana sarà probabilmente abbastanza, sei pregato di vedere [qui](https://github.com/disconnectme/disconnect-tracking-protection/commits/master) per le modifiche recenti agli elenchi.
**(160) Puoi aggiungere l'eliminazione permanente dei messaggi senza conferma?**
L'eliminazione permanente significa che i messaggi saranno persi *irreversibilmente* e per prevenire che si verifichi accidentalmente, questa deve essere sempre confermata. Anche con una conferma, alcune persone molto arrabbiate che hanno perso alcuni dei loro messaggi per colpa propria mi hanno contattato, un'esperienza alquanto spiacevole :-(
Avanzate: il flag di eliminazione di IMAP insieme al comando EXPUNGE non è supportabile perché sia i server email che non tutte le persone possono gestirlo, rischiando la perdita imprevista dei messaggi. Un fattore complicante è che non tutti i server email supportano [UID EXPUNGE](https://tools.ietf.org/html/rfc4315).
**(161) Puoi aggiungere un'impostazione per cambiare il colore primario e secondario?***
Se potessi, aggiungere un'impostazione per selezionare colori primari e secondari subito, ma sfortunatamente i temi di Android sono fissi, vedi [qui](https://stackoverflow.com/a/26511725/1794097) ad esempio, quindi è impossibile.
**(162) IMAP NOTIFY è supportato?***
Sì, [IMAP NOTIFY](https://tools.ietf.org/html/rfc5465) è stato supportato dalla versione 1.1413.
Il supporto di IMAP NOTIFY significa che le notifiche per i messaggi aggiunti, modificati o eliminati di tutte le cartelle *iscritte* saranno richieste e se una notifica è ricevuta per una cartella iscritta, quella sarà sincronizzata. La sincronizzazione per le cartelle iscritte può dunque essere disabilitata, salvando le connessioni della cartella al server email.
**Importante**: i messaggi push (=sempre sincronizzati) per la casella di posta in arrivo e la gestione dell'abbonamento (impostazioni di ricevimento) devono essere abilitati.
**Importante**: gran parte dei server email non lo supportano! Puoi controllare il registro tramite il menu di navigazione se un server email supporta la funzionalità NOTIFY.
**(163) Cos'è la classificazione del messaggio?**
**This is an experimental feature**
Message classification will attempt to automatically group emails into classes, based on their contents, using [Bayesian statistics](https://en.wikipedia.org/wiki/Bayesian_statistics). In the context of FairEmail, a folder is a class.
You can enable message classification in the miscellaneous settings. This will enable learning mode only.
Each folder has an option to enable automatic message classification. When this is turned on, new messages in other folders which the classifier thinks belong to that folder will be automatically moved.
Classification should be considered as a best guess - it might be a wrong guess, or the classifier might not be confident enough to make any guess. If the classifier is unsure, it will simply leave an email where it is.
Classification will be done for new messages in the inbox, spam folder and user folders only. You can clear local messages (long press a folder in the folder list of an account) and synchronize the messages again to classify existing messages.
Moving a message on the device will reclassify the message. Moving a message from another email client will not result in reclassification because IMAP does not support 'moved' notifications.
Classification is optimized to use as little resources as possible, but will inevitably use some extra battery power.
You can delete all classification data by turning classification three times off.
Automatic message classification is a pro feature, except for the spam folder.
## Ricevi supporto
FairEmail is supported on smartphones, tablets and ChromeOS only.
Only the latest Play store version and latest GitHub release are supported. The F-Droid build is supported only if the version number is the same as the version number of the latest GitHub release. This also means that downgrading is not supported.
There is no support on things that are not directly related to FairEmail.
There is no support on building and developing things by yourself.
Requested features should:
* be useful to most people
* not complicate the usage of FairEmail
* fit within the philosophy of FairEmail (privacy oriented, security minded)
* comply with common standards (IMAP, SMTP, etc)
Features not fulfilling these requirements will likely be rejected. This is also to keep maintenance and support in the long term feasible.
