I guess some MTAs in general, I think qmail behaves the same. I'm bombed 
each night around 02:00 local time, though, it does not bother me too 
much. Have you considered using an IDS-alike before port 25? I mean you 
could drop/reject SYN packets from the same host, if you've seen more than 
n in the last minute from the same host.
