SpamSieve, the spam filtering software from Michael’s Macintosh Software, has been updated to version 2.0, which extracts more information from each message and integrates with Eudora 6.
SpamSieve is a utility designed to bring spam filtering capabilities similar to those found in Apple’s Mail to other e-mail clients. SpamSieve “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. Like Apple’s Mail application, you can train SpamSieve over time. And it doesn’t delete messages; it merely marks them so you can take whatever action you deem appropriate.
SpamSpieve 2.0 adds a blocklist and a whitelist, which are automatically maintained based on the senders of messages with which the application is trained. The blocklist is designed to ensure that all messages from known spammers are caught and to speed processing for such messages. The whitelist makes sure that certain messages don’t get marked as spam; this was possible before version 2.0, but the process has been streamlined.
SpamSieve can now play a sound or bounce its Dock icon after a batch of non-spam messages has arrived. This is meant to replace your e-mail client’s new mail notification, so that it won’t go off if all the new messages are spam. Version 2.0 parses HTML so that it can better extract relevant information from HTML messages, and also handle various HTML-based tricks that spammers use to fool filters. There’s also a new method of calculating word probabilities that purportedly makes SpamSieve better at discerning which words in the message are important.
SpamSieve 2.0 requires Mac OS X (10.1.5 or later) and works with Emailer, Entourage, Eudora 5.2 or later, Mailsmith and PowerMail. A demo is available; registration is US$25.
