I'm the administrator for the accounts at our office and have been asked to monitor everyone's incoming and outgoing mail for suspicious activity. Is there any way to get copies of everything going through the server without the users being aware?
It needs to be done in such a manner that even if they change their passwords, it won't have an effect and I've searched the control panel and knowledge base and found nothing that will help me.
If anyone has suggestions, please let me know. My boss is quite insistent this be done immediately. Thanks!
