I tried to use the amavisd-new from Dag's site.  I ended up removing 
it.  I couldn't verify whether or not it was actually using 
SpamAssassin.  The log file said that amavis was finding SA, but I 
wasn't finding any of the SA headers in the email I was passing through 
the server.  I couldn't figure out how to troubleshoot the problem, and 
was running out of time.  Also, I couldn't be sure, but it seemed like 
it was calling SA cold for each email and eating the resources accordingly.

I ended up using spamd (the Spam Assassin daemon) and calling spamc from 
a procmail script.  Then I installed clamd (the clamav daemon) and 
clamassassin (a procmail interface for clamdscan) and call that with a 
procmail script as well.  I'm happy with the performance, and I can 
monitor what clamav and spamassassin are doing, which I like.  At this 
point I'm considering adding another virus scanner for redundancy, but 
the clamav folks seem to respond to new virii pretty quickly.

My old email server used Mailscanner with SA and f-prot.  The only 
complaint I had with it was that you have to install postfix twice, and 
sometimes email would get hung up.

My $0.02 US. :)
