I figured. I block on the ingress so it is minimal network but maximum
pain in the A$$.
Thanks.

abusers never stop, others possibly.
I have a server I have blocked in my firewall. It continues to try
and is blocked as many as 4000+ times a day.
If postscreen was set to deny it, would that signal the server and
limit the attempts?
The sending IP most likely would not care. It's better to keep that IP
in firewall, maybe dropping packets, maybe tarpitting them (most
probably requires addons to your firewall).
