Spamassassin works.  If you have Microsoft machines in your setup, you
probably want clamav (antivirus) or similar as well.  And finally, do
look into running some sort of greylisting (possibly supplemented with
a tarpit for known bad senders).  

The greylisting/tarpitting part is really easy to do with PF, see eg

filtering for fun and profit tutorial)
