This is the Napster of SpamFighting....it's SpamNet...it's fantastic. I tried SpamAssassin Pro, but after messing with it, I stuck with SpamNet. The only drawback is that you need to open up port 2703 or use socks...but since it's outgoing it's not a big deal. It litterally saves me from messing with >= 50 spam emails a day.
