I must be clueless (or my server has never been the target of a Dictionary attack). How much processing overhead does IMail go through to give a 550 Invalid User reply? It shouldn't even get to the data exchange. Seems it would not be very resource intensive. Of course, I'm running under 500 users, and they are in the IMail database. Maybe you are seeing database latencies? But that should affect the front end processor too.
I must be missing something.

IMGate doesn't even show any signs of slowing during dictionary attacks, and saved my IMail server from bogging down. I'm running IMGate on a 400 MHz 396Mb RAM machine with one ATA66 hard drive.
