Protect my server from SPAM sent ... by MY OWN USERS!!!

[jaimet]

Hi,


I've detected one of my customers that is sending hundreds of thousands of spam emails with his account on my server. I do not support any form of spam on my server, so i've told him that if he does it again, i'll kick his butt with a baseball stick.

But rarther than this, i want to implement some sw protection if possible. So the question is:

Is possible to limit the mails per day or per hour in plesk , so i can be sure that noone is sending more than, let's say 1000 emails per day?

There are a few options, if you're using postfix policyd can be used to put a quotas around what a user/domain/server can send in a specific time period. In qmail you can use qmail-scanner to scan outbound mail for spam (highly useful for catching spam attacks on web scripts)
