[IMail Forum] Limit on outgoing messages

[Don Might]

Hello.   Is there any way to impose a limit on outgoing messages?  One of my users contracted a virus sometime yesterday evening.  Between sometime after I left yesterday evening around 5:00 and I came into the office this morning at 7:00, this user sent 87,000 emails out.  I want to prevent this from ever happening again.   Besides simply monitoring the server, what are the best techniques to prevent such an occurrence?   Thanks in advance.   Don
