SpamSieve 1.0

is now available. "Like your professional e-mail client, but jealous of Mail.app's spam filter? SpamSieve brings powerful Bayesian spam filtering to Mailsmith and Entourage. It learns what your spam looks like, so itcan 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. Price: $10 (shareware) for More Info."
