I use sqlgrey, provided by TSL RPM.

I forgot to mention:
  The latest amavisd-new has a feature called PenPals. If you configure
  amavisd-new so use sql for all things if can also keep track on who
  your users send email to. When a message is received amavisd-new checks
  to see if you have emailed them recently, and if you have you probably
  want the reply. It then subtracts a configurable amount from the spam
  score.
