Email Client Software

Eudura
Eudora is a classic, powerful, flexible and efficient email client that cans spam precisely, too, and shows nary a weakness. Leveraging the statistical spam filter to organize good mail would be nice, though. Some of Eudora's best features (the spam filter and fast search) are only available in the paid version.
