An extensible mail notification daemon

Mailnag is a daemon program that checks POP3 and IMAP servers for new mail.
On mail arrival it performs various actions provided by plugins.
Mailnag comes with a set of desktop-independent default plugins for
visual/sound notifications, script execution etc. and can be extended
with additional plugins easily.

This project needs your support!
If you like Mailnag, please help to keep it going by contributing code,
reporting/fixing bugs, translating strings into your native language,
writing docs or by making a donation.

Default Mail Client

Clicking a mail notification popup will open the default mail client specified in GNOME Control Center -> Details -> Default Applications.
If you're a webmail (e.g. gmail) user and want your account to be launched in a browser, please install a tool like gnome-gmail.

Desktop Integration

By default, Mailnag emits libnotify notifications, which work fine on most desktop environments
but are visible for a few seconds only. If you like to have a tighter desktop integration
(e.g. a permanently visible indicator in your top panel) you have to install an appropriate
extension/plugin for your desktop shell. Currently the following desktop shells are supported:

Furthermore, I highly recommend GNOME users to install the GOA plugin,
which makes Mailnag aware of email accounts specified in GNOME Online Accounts.


Gmail doesn't work
If Mailnag is unable to connect to your Gmail account, please try the following solutions:

  • Install the GOA plugin to connect via GNOME online accounts
  • Have a look at the FAQ
  • Try to apply this workaround

Other issues
If Mailnag doesn't work properly for you, either examine the system log for errors (journalctl -b _COMM=mailnag) or run mailnag in a terminal and observe the output.
