I don't think SpamAssassin is the first step to stopping spam.  We can 
do that too, but there are some other less CPU/admin intensive that we 
should do first.

In my experience graylisting is a good start.  My mail server is similar 
to CLUE's--a few addresses get mail, several more forward mail, and 
that's it.  It's been greater than 90% effective for me.

But I don't know anything about spam so I'd find someone who has a good 
description of layered methods.  These aren't that but you can also look at:

spam filtering)
