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.
