I'm running Exchange 2003 SP1. In my only SMTP connector, there is a delivery restrictions tab that allows the restriction of outbound messages by user or group. It isn't working. I can select the radio button "reject message from everyone by default" or I can add users/groups to the reject messages from box at the bottom of the window, and it simply ignores it. However, on the same SMTP connector, if I set a size limit on another tab, the user will get a message about the size limit.
I've run gpupdate, restarted Exchange services and restarted the entire server without effect. Do you guys have any ideas why this isn't working? It's frustrating to change a setting only to have it completely ignored.
