Thunderbird is Mozilla's solution to the e-mail client.
Earlybird is the "unbranded" version of Thunderbird. It can be enabled when the
bindist is set.

emerge --ask mail-client/thunderbird
Emerging Thunderbird is a long process, a pre-compiled (binary) version exists for users who want a shorter install time:
emerge --ask mail-client/thunderbird-bin
Note that behavior of the pre-compiled version may be different in many ways including the choice of default applications for URLs.
To ensure Thunderbird is being used by other applications as the default application for handling
mailto: links, run:
xdg-mime default thunderbird.desktop x-scheme-handler/mailto
Thunderbird has a variety of keyboard shortcuts built-in. A full listing can be viewed on the Thunderbird support page.
Mail notification sound
Mail notification sound needs a sound theme to work, see.
Thunderbird supports instant messaging and chat using IRC, XMPP, and Twitter. Instructions for configuration can be found on the instant message and chat support page.
Thunderbird has a build in calendar function called lightning.
Filter rules can be configured within Thunderbird to short or apply rules to incoming or outgoing messages. For mail accounts which are subscribed to many mailing lists, or which receive a lot of mail from known sending addresses, filter rules enable a tidy inbox. As of 2023-06-26, Thunderbird v102.12.0 has no way to exclusively export filter rule sets from one system to another. See the Backing up or moving filter rules section for details on recreating rule sets when using Thunderbird on multiple devices.
Unfortunately, there are known bugs regarding filter rules which prevent certain rules from automatically applying as expected. To work around, the user can manually trigger the rule on the appropriate folder as necessary.
Backing up or moving filter rules
Filter rules are stored in a file entitled msgFilterRules.dat, which is located under the ~/.thunderbird/<Profile name>/ directory on Linux systems. When wishing to backup filter rules or copy them to another Thunderbird client, this file will need located. Follow the below steps:
- Locate the profile directory for the relevant mail account. With Thunderbird open:
- Open the Menu Bar toolbar > Tools > Export > Open profile folder link
- Select: Help > More Troubleshooting Information > Under Application Basics located the Profile Directory row, and click Open Directory.
- Either of the above steps should a file browser window showing contents of profile name folder. This should be under the ~/.thunderbird/<Profile name>/ directory as noted above.
- Close all running instances of Thunderbird. This ensures all files are written (synced) into the profile directory.
- Locate the msgFilterRules.dat by drilling into directories until it is discovered, or by opening a shell within the profile directory and running the following command:
find . -name 'msgFilterRules.dat'
- Once discovered, move this file to the backup location and/or into the profile using the same mail account on another device.
- Firefox — Mozilla's web browser.
