On Exchange 2010, can anyone help me point on how to setup certain mailbox to be allowed to send to specific domain. My organization has a large forest and I am in one of the child domain. I do not want user in my child domain to be able to send out to other domain and also to an external email.

    Accepted Solution

    You would control it by using the following conditions....

    When the From Address matches text Patterns  ( Set pattern to when is the sender)
    When a recipient's properties match text pattern. (e.g. Property EMAIL: Text pattern

    Now on the actions you can select for example
    Send rejection message to sender with enhanced code. (E.g. "you cant email",5.7.999)

    Hope that gets you on the right track.
