    Hi Dave,

    From looking at your message, you were trying to send a message inbound to a
    recipient that was on that Exchange Server. If that is so, open up Exchange
    System Manager and expand Recipients. You will see Recipient Policies. Click
    on this and on the right you should see Default Recipient Policy. Make sure
    that the domain that you are trying to accept for is listed on the Email
    Addresses tab. If not, add an SMTP address with that domain and it should
    work.
