I just setup forwarders for anything I use publically. And I have a seperate 'nospam@' account as well. My main account was getting a lot of spam, but it was almost all from one forwarder. So I just killed that one, and renamed (yahoo@ -> yahoo2@) With SpamAssasion and some filtering running, it should cut me spam down to done (I accidently killed my filters a few weeks ago, which is the main reason I had to change.) My filters have been going for like 6-12 months at work. I hardly ever see a piece of spam.
