Is there any way to limit the number of emails sent per user
account/uid per day? I have searched archives, and while I'm sure this
must have been asked numerous times before, I can find no relevant
data. Someone suggested interposing a script before the qmail-queue
(actually replacing this with a script) that tracks the number of
messages per user, then calls qmail-queue if the user hasn't reached
their quota. That's more of a programming task then I am prepared to
contend with. Any other suggestions?
