Michael Tsai has released SpamSieve 2.4, an update to his Bayesian spam filtering utility for popular email clients such as Apple Mail, Mailsmith, Entourage, PowerMail, and Eudora. The new version offers numerous changes, including: various changes to the Bayesian engine to improve accuracy; the addition of some heuristics for detecting phishes; the ability of Apple Mail messages to be filed into different mailboxes based on how “spammy” they are; the addition of support for the new (non-haiku) Habeas headers; and much, much more. SpamSieve is priced at US$25 and requires Mac OS X 10.2.8 or later (10.3.5 or later recommended).
