We have had issue in the past where a user replies to a phish email, there mailbox get compromised and hundreds of email get send from the users mailbox cause one of our servers to get blacklisted.

How we do have a security department that is suppose to be proactive able this type of this but that is another issue.

Anyway is there a way to place a limit on the number of emails a user can send outbound and if that limit is reached an email is sent the the Exchange Administrators?

Is that an Exchange 2013? 2012 doesn't exist.

You can use message throttling but some additional software on your smarthost or having an appliance that checks for spam/viruses and so on is recommended.

Technet really has vast resources on the topis and would recommend you to read and play with the settings on your Exchange. Before I was using an applience that looks after it I setup and used the Exchange capabilities to the max in terms of anti-spam prevention for receiving and sending as well.

Check this link and use Exchange options before you venture out and buy some third party SW
