Anyone got any experience with SpamAssassin and/or integrating it with 
qmail?

I have a small MTA (40ish users) running qmail, and I'm about ready to 
start filtering mail through SpamAssassin.  I have installed SA and done 
some initial tests to see that it's working.  I have also been running 
qmail patched with the QMAILQUEUE patch for a couple weeks, in 
preperation for linking in filtering software.

I now need to tweak the SA config, and start processing mail.  Any 
preferred "tweaks" to the default SA setup would be appreciated (note: 
I'm already planning on using the daemonized mode), along with any 
advice on how best to call SA from qmail.  I'm currently planning on 
setting the QMAILQUEUE variable in tcpserver (just like RCPTHOSTS) to 
run spamc so external messages will get scanned for SPAM prior to 
entering the queue.

Other options that look promising include setting up qmail-qfilter or 
qmail-scanner.  I don't have any virus scanning software, so it looks 
like the complexity of qmail-scanner is currently overkill, and I don't 
think I need to use qmail-qfilter if I only want to run SpamAssassin 
(which pretty much includes all the SPAM tests I was wanting to check 
anyway, including optional support for bayesian filtering).

NOTE:  I am currently planning on using (and have installed) the 
optional razor filter for SpamAssassin.  Any suggestions on configuring 
or using razor within SA would also be greatly appreciated.
