By learning from the very messages that you receive, SpamSieve is able to block nearly all of your spam, without putting your good messages in the spam mailbox.
* Powerful Bayesian spam filtering results in high accuracy and almost no false positives. It adapts to the mail that you receive to get even better with time. Some other e-mail clients include Bayesian filters, but SpamSieve is more accurate. * Integrates with your e-mail client for a superior user experience. Plus, you get the same great filtering if you ever switch e-mail clients or use more than one at a time. * Integrates with the Mac OS X Address Book (and also Eudora’s and Entourage’s address books) so that messages from friends and colleagues are never marked as spam. * Automatically maintains a blocklist so that it can instantly adapt to spam messages sent from particular addresses, and catch 100% of them. * Automatically maintains a whitelist to guarantee that messages from particular senders or mailing lists are never marked as spam, without cluttering your address book with these addresses. * You can customize the whitelist and blocklist, adding sophisticated rules that match various message headers, or the message body. The rules can match text in a variety of ways, including using regular expressions. * Can use the Habeas SafeList, which indicates messages that are Not Spam, as well as the “ADV” subject tag indicating that a message is spam.
