amavisd-new  with spamassassin and anti virus scanner, clamav with
sanesecurity rules
use enforcing rules in mail server, like block hosts with no DNS/rDNS
Enforce SPF, publish SPF with hardfail
use DNSBL's in your mail server, spamhaus, spamcop, spam.sorbs, and
more etc.
milter regex to stop dynamic/suspect  hosts 

There is no one solution, the solution, is a box of many tricks
You might get the odd false blocking, but if system opers can not be
bothered running a compliant network with standardised naming
conventions for servers, then it is not my problem, and we have had very
very very few complaints about this type of policy in over a decade. If
someoine sooks to you, educate them, dont whitelist them.
