Michael Tsai has released SpamSieve 2.4.2, 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: SpamSieve is now much better at catching a new type of spam message that previous versions had been inconsistent at catching; worked around some more spammer tricks to improve accuracy; improved phish detection; and much more. SpamSieve is priced at US$25 and requires Mac OS X 10.2.8 or later (10.3.5 or later recommended).
