I have been using "mailwasher", its a free download program that lets you view yout email or headers without downloading them and it compares them to spammer lists. It then allows you to blacklist or bounce the offending messages.
NEVER EVER bounce messages!
Why? Because the return address is FORGED! You end up mail-bombing an innocent.
Take a look at SpamBayes. It learns what you deem to be non-spam. A verison of it was ported to Windows: http://spambayes.sourceforge.net/windows.html Mozilla has a similar built-in feature. http://www.mozilla.org/releases/
