SpamSieve 1.3 is now available.
Like your professional e-mail client, but jealous of Mail.app’s spam
filter? SpamSieve brings powerful Bayesian spam filtering to other popular
e-mail clients. It learns what your spam looks like, so it can block nearly
all of it. It also learns what your good messages look like, so it won’t
confuse them with spam. Other spam filters get worse over time as spammers
adapt to their rules; SpamSieve actually gets better over time as you train
it with more messages. SpamSieve doesn’t delete any messages–it only marks
them in your e-mail client–so you’ll never lose any mail. SpamSieve works
with any number of mail accounts, of whatever types are supported by your
e-mail software (e.g. POP, IMAP, Hotmail, AOL).
Requirements: Mac OS X 10.1 or later
Supports: Emailer, Eudora 5.2, Entourage, Mailsmith, PowerMail
Price: $20 (shareware); free upgrade from 1.0-1.2.2
