SpamSieve 2.6 released
Michael Tsai today released SpamSieve 2.6, an update to the popular Bayesian spam filtering for Mac e-mail clients. The software "learns" what spam looks like, so it can block nearly all of it, according to the company. Using your Address Boo, it also learns what good messages look like, so it won't confuse them with spam. The developer says that while other spam filters get worse over time as spammers adapt to their rules, SpamSieve actually gets better. The software 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) and supports Apple Mail, Emailer, Entourage, Eudora, GyazMail, Mailsmith, Outlook Express 5, PowerMaiil, and now Mozilla Thunderbird.
Version 2.6 offers improves detection of image spams and phishing messages as well as offers various message analysis improvements to increase the accuracy of the Bayesian filter. The update also brings improved compatibility with pre-release versions of Mac OS X 10.5 Leopard, improves installation and use for Mail users with a non-modal plugin, and adds Software Update compatibility with HTTP proxies and FileVault.
The software requires Mac OS X 10.2.8 or later and costs $30. It is a free update to owners of the previous version.
