Popfile is an e-mail proxy that filters spam based on how you train it. It takes some initial effort to get it over the hump, but it achieves over 99% accuracy over the long term.
I believe they also have an nntp proxy for filtering usenet, too.
You won't be sorry.

Ordinarily either Lisa Minter or myself get in here and flush the spam
