Another coomon mail agent to try is evolution, especially if you are a fan of GNOME, since it sports heavy integration with the desktop, and is the preferred agent for GNOME.
It's very Outlookish, if you like that sort of thing. It has several advantages, including support for PGP/GPG, HTML, MIME and other common email standards. Unlike some of the other mail programs mentioned thus far, it also supports IMAP (including v4) and even *cringe* Microsoft Exchange servers. (Sorry fellas.) It also supports message threading views, etc. It's highly maintained, and development is handled by the GNOME Foundation and Novell. Thunderbird's spam handling is better out of the box, but you can setup a filter to tie directly into SpamAssassin and take care of that.
