If you are using fetchmail to deliver to your own sendmail, you 
are already halfway there.
Use procmail to run all emails through spamassassin, and then let 
procmail or your MUA sort the emails based on the spamassassin 
results.
I use this approach, and after a surprisingly small amount of 
tweaking spamassassin now catches ~99 out of a 100 spams, and has 
amazingly few false positives.

There are some tutorials about procmail on 
http://www.onlamp.com/bsd/ that deals with catching spam. Even if 
they dont explain spamassassin, it should get you started.
