I had MailScanner installed and it worked great.  I switched to 
Amavis-new because I was afraid the authors of postfix would stop 
support for MailScanner.  Amavis-new has the same results as far as I 
can tell.

I agree with your conclusions.  Greylisting and a tight postfix set up 
has my Spamassassin mostly idle.  In fact, I have eliminated bayes from 
spamassassin because I do not get enough spam to train it well.  I do 
use rulesdujour in spammassissn to get most of the few who make it through.
