Just an observation, but is it necessary for the non-mail command
limit to be configured right on the exact minimum threshold of needed
commands in a normal mail session?
Rather, couldn't you just set it to something arbitrary, say 15?
At least then it would catch any major abuse.
Are non-mail commands being abused by spammers or DOSsers?
