Cactus Spam Filter combines all these characteristics solidly, but a few oddities counteract. Using Bayesian statistics, Cactus Spam Filter can identify the junk — at least after some training, a bit more than with other programs in my testing.
Unfortunately, Cactus Spam Filter can mark spam only in the message Subject, though this is a minor problem. If you use anything but POP, you'll find Cactus Spam Filter restriction to POP accounts more limiting. But with these POP accounts, Cactus Spam Filter does indeed work sans configuration.
If your email program is not yet listed, all you have to do is add it and Cactus Spam Filter will automatically filter all mail you download in it. You can — or must, rather — then train mistakes in Cactus, which could be a tad easier: Cactus Spam Filter always displays the full list of filtered messages with no way to search. Sorting by spam score can prove helpful, though.
