  2. Check that the mail route listener is configured correctly on the internal NIC according to the MX record settings:

    1. In the Forefront TMG Management console, in the tree, click E-Mail Policy node.

    2. Select Internal_Mail_Servers, and in the Tasks pane, click Edit Selected Route.

    3. On the Routing tab, check the Internal mail servers.

    4. On the Domains tab, check the accepted domains.

    5. On the Listener tab, check the FQDN or IP address….

  3. Telnet into the MX record IP from the internal network. Check that the response receives the FQDN defined in the SMTP route.
