That should happen pretty quickly. I gather that the new Mail.app in Jaguar
uses some flavor of Bayesian filter, which is why it needs to be 'trained'
by showing it examples of 'good' and 'bad' messages. I've just recently
started using a Bayesian filter with Mailsmith[1], and can say from my
experience that once the filter has a sufficiently large corpus of words (a
few hundred messages worth), it becomes remarkably accurate at
distinguishing spam from legitimate mail.

If you're interested in learning out about Bayesian filters as applied to
spam filtering, check out Paul Graham's 'A Plan for Spam' at
<http://www.paulgraham.com/spam.html>. It makes me start to wish that SIMS
could do content-based filtering. I would drop IP blacklists in an instant
in favor of a workable server-side Bayesian filter. There would probably be
a few interesting problems to solve in implementing such a filter on the
server side, though, not the least of which would be creating a mechanism
for users to add messages to the corpus.

works with Entourage and PowerMail, and the author says that he plans to
eventually support Eudora. <http://www.c-command.com/spamsieve/>
