Doesn't postfix have the ability to reject hosts or domains?
I base a host_reject line in exim with a host/domain list i get from
http://www.stearns.org/sa-blacklist/sa-blacklist.current
This way these folks get rejected at smtp time, and the message is not
processed. I also subscribe to about 5 blacklists, and use spam assassin.
Are you using blacklists? That should cut out the most aggravating stuff.
iptables or any other packet filter is really the wrong tool here anyway.
