I'm looking for an alternative for Thunderbird. I use Linux. An alternative should meet three requirements:
- support multiple email accounts
- be able to reside in tray, and does not depend on helpers like Alltray¹ for this
- be able to display information about new mail
¹ AllTray is an application which docks other application software into the system tray

. Please feel free to edit my question if you find it vague.
