How to determine how many emails a users sends out in a day
Posted on 2012-03-14
Over the past couple of weeks, we have been blacklisted by our ISP for sending out more than 500 emails in an hour. I have 40 users and I suspect somebody is doing something they shouldn't be doing (i.e. sending out mass emails)
Is there a way in Exchange 2007 to determine how many emails each user sends in a given day, preferably by the hour. The emails in question are going out after hours as if they are scheduled. If I could locate the user or IP, I can take appropriate action.
Secondly, if the above is not possible, if there a way to throttle the number of outgoing emails to under 500 per hour?
