I have followed the instructions from amset.com regarding restricing a user to only sending messages internally. I had to create the connector, added my only server to the bridgehead list, use DNS is selected, SMTP * is listed as an address space, and the one user is in the Restricted box for restrictions.
I've restarted the SMTP and Routing Engine services, as well as the users Outlook but he is still able to send messages externally.
Am I missing something? Does the user need to reboot?
