  • i did the following to get this worked...

    Exchange Management Console --> Server Configuration --> Hub Transport. (Dont touch the default receive connector)

    click in the Receive connectors pane and select new receive connector.
    Give it some name like "Relay"  from Customer from the drop down list.
    Click next.

    Remote Network settings --> Delete all the IP and
    add only IP which you would like to authorize to relay e-mail from your
    server . Click next . click new. Click Finish

    From the new receive connector properties:

    On the Permission Groups tab : only select Exchange servers.

    On Authentication tab :  Only select "Externally Secured (for example, with IPSsec).

    Click OK and try  to relay emails through your server.
