Hey guys

anyone knows if there's a tool or way to detect users sending spam? It always happens that one of my thousands of pop users, -at some moment- get infected with a trojan that sends mail trough their computer without they knowing of being aware of it.

I usually try to keep an open terminal with: tail -f /var/log/exim/mainlog to check for any unusual activity, but sometimes happens that you gotta sleep, or do other stuff.. you miss a guy sending spam.. and BANG! before you even know it you are blacklisted on barracudacentral or some other place :eek:
 
Check these forums for how to place limits on the amount of emails a user (not a pop user unfortunately) can send. Then you'll get an early warning, and you'll also get information on how many emails are being sent.
