I was wondering what people here are doing to prevent authorized users

With the new rollout of courier we're forcing everyone to use SMTP Auth,
so atleast we don't show up as open relays etc. But, what can one do to
prevent an authorized user to send spam ? They could authorize and send
the same message to 50 recipients each, 500 times.. and we would still
be contributing to spam.. once I catch them, I can stop them from
sending mail. but what does one do to prevent the problem in the first
place ?.
That completely depends on what you consider to be spam. I guess you're
thinking of constraining the number of messages (recipients) a user can
send within a certain amount of time, right? I have never thought about
how to implement this with courier (or any other MTA), but would
certainly be interested in it!
Old need. Old solution. 'tarpit'. A Qmail patch is here:

Must be one around for courier-mta as well?
