Is it possible to configure postfix with a threshold where if a

We occasionally have users on our network with infected machines, or
perhaps they are actually spammers... and I'd like a mechanism by
which a "power user" can get put into "time out"... and then re-
enable access after a period of time.
(We manage a network of wi-fi hotpsots around the country, so
blocking an IP would block smtp access for all of the users at that
hotspot, thus the automatic re-enabling of access after 30mins or so).
Do this in a policy server like policyd.
