Hi Xchange Gurus ,
Have problem with my exchange.
Two windows 2k servers, one acting a communication server on which DSL is insatalled and other is
Domain controller cum Exchange Server.
All the outbound messages are forwarded to Coummunication Server which than relays to the foriegn domain.
But have problem with one of the domain.... whenever user send the message to abc@abc.com,
immidiately NDR comes back stating
The Following receipt could not be reached;
abc@abc.com on 24/jul/06 10:01 Am
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<gwsr03.dxbdom04 #5.7.1 smtp;550 5.7.1 Unable to relay for abc@abc.com>
