Have you already tried spamassasin-milter and clamav-milter packages? They can say reject after DATA.

If you do a greylisting before DATA (eg. with postgrey), than many zombies will bounce back from you, and it will relese many cpu time for you;-)
Yes,Greylisting is wonderful magic against evil SPAM spirits, I fear the day somebody ports a RFC compliment MTA to the zombie platform.
btw, we also figure to do DNSBL after greylisting in front of virus and spamassassin. With spamassassin we figure to reduce timeouts by turning off the network checks.
So far we've had some timeouts, but checking IP# against whois suggests that they are people we want to connect with anyway.
Moving to a much, much beefier box should reduce even those timeouts.
