We are running FreeBSD 4.8 on a dual 1.8 ghz with 2GB ram and processing
60k+ messages a day inbound. I don't run spamassassin except for a very
small number of domains ( 2 of 250 ). MailScanner 4.41.6, also running
mailscannerMRTG. I never have more than 20 messages in the incoming
queue, no more than 11 copies of mailscanner running, load is around 1.

I would try turning off the SA dns checks, I've found them to be huge
load. I don't run them on any of my SA installs, I do use spamcop at the
smtp level.
