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

When I set the type to MX and check with server1, and it points
properly to
However still the mails to useraccount@xxxxxxxxxxxxxxxx bounce back saying
host is unknown.
