anyhoo, two questions:

probably only by putting something between SIMS and the attacker - firewall, ASSP or some other anti-spam server, etc.

2> is there a reason why, after a few hours or days of this, the SMTP part of SIMS would simply stop responding? i can see it in the logs - it handles SMTP fine, delivering/bouncing/routing messages one minute. the next minute, it's crickets. POP still handles connections and delivers mail to clients that log in, but i have to restart SIMS to get SMTP to respond.

How's your memory in this machine?
