Spamassassin is the way to go, but make sure you use sa-update to update 
the rules on a daily basis.  In addition you may want to consider the  
"FuzzyOCR" plugin which will (help?) stop the annoying image spam (I 
haven't seen one of those in months).

Be forewarned,  spamassassin can be a memory pig, I start it with the 
following command:

/usr/bin/spamd -c -m 20 -d -r /var/run/spamd.pid

Right now there are three spamd processes running each using roughly 
80Meg of memory for a total of ~240Meg.  If I start getting a lot of 
incoming email the number of processes will climb and so will the memory 
usage.
