current path of mail...

postfix receives message -> checks against dnsbl -> passed to postgrey
for greylisting which deffers accepting a msg for 300 seconds -> then
sent to amavisd which sends the message to clamav then to
spammassassin -> amavisd then sends it back to postfix for final
delivery

this was a topic on this list a couple months ago about things we can
tweak:  adding any number of envelope checking to prevent postfix from
every accepting connections from hosts (dnsbl), checking for non-RFC
compliant smtp behavior, and working on spamassassins rules.
