Well, I am using postfix (not telling you to change) but I have set up some options to check the host that is connecting (make a dns resolution of the name that is trying to connect) for example if it says it is mail.acme.com and that does not resolv in dns it rejects.. also I have it to check the domain, if acme.com in the From header does not exist postfix also rejects... more stuff I have also placed a limit for 100K per mail since rarely I receive anything bigger than that (so I dont receive this viruses neither the notifications, though I understand this can be too drastic for some people), with all this checks I reduced 1000 mails per 12 hours to 0 or 3 per day.
