  • you do not have permission to send NDR.

    Am running an exchange 2000 with outlook 2003.

    Of resent when i send mail to a certain domain, it does not send and this is the NDR i get.

    [email protected] domain on 12/08/2006 5:24 PM
    You do not have permission to send to this recipient. For assistance, contact your system administrator.
    <my domain #5.7.1 smtp;550 5.7.1 <[email protected] domain>... Relaying denied. IP name possibly forged [my IP]>

    This happens to only one domain (external) and to all users in our company who try sending to that domain.

    When you send mail from outside our company (another domain) it sends fine.

    Mail is sent through the exchange default virtual server, not smtp connector and have a smart host set.

    What could be the cause of the NDR and how do i resolve it?

    Thank you.

    This problem can cause from several reasons:

    1. The server on the other side has a temp problem.
    2. You have a DNS recorders problem (usually - don't have PTR).
    3. Check the next location and see if the DNS (FQDN) is written correctly and that it is valid:
    Default Virtual SMTP Server
    Fully Qualified Domain name

    Write the DNS domain name of your domain (with the server name)

    And try again.
