Guide Review - Spam Bully 4.3 - Spam Filter
It combines several approaches: approved and banned senders, DNS blacklist lookups, challenging messages for unknown senders and Bayesian spam filtering. Though Spam Bully's default combination of filtering tactics is not bad, you can probably still ignore all but the latter safely.
You don't have to fiddle with senders (which Spam Bully makes easy, though) or annoy new contacts. You can avoid the time-consuming blackhole list lookups. Concentrate and rely on the Bayesian filtering instead. The initial corpus is okay, but Spam Bully's filters do a really great job detecting spam (and viruses, too) after some training.
Unfortunately, the filter learns only from mistakes, not from its own correct classifications. Solid integration with Windows Mail, Outlook Express and Outlook makes Spam Bully easy to use, though support for IMAP and Hotmail accounts in Outlook Express and Windows Mail would be a plus.
Using Spam Bully's user-friendly email analysis, you can usually pinpoint the path of spam accurately, and report spammers to their ISPs is easy, too. Spam Bully even lets you "punish" spammers by hitting them with traffic. I'd counsel against using this, though.
It's still a pity you're out of luck if you're not using one of the Microsoft email clients.
