Hi,
Thanks for the response.
This problem is common for all my mail accounts in the server. So how to
add that username@xxxxxxxxxxxxxxxx  in e mail address lists of user
accounts. Can u guide me .
As for nslookup test it works fine..
When I set the type to MX and check with server1, and test.com it points
properly to server1.test.com
However still the mails to useraccount@xxxxxxxxxxxxxxxx bounce back saying
host is unknown.
