Was that some wrappered service? Looked like tcp_wrappers.
I think a router with enough memory would be a better performer
for filtering activies at that layer.

I did go ahead and install the relay denial rulesets published on 
sendmail.org for 8.8.x and they work fine. Cyberpromo appears to 
have been using "Cyberbomber" on our ports. 

I guess I'm naive, but I thought NAPS wanted to stop this kind  
of thing, and most had explicit rules about it. Guess not. Back to
the clue-store with me. :-/
