[cobalt-users] mail loops back to me (MX problem?)

["Fathi Said" <fathi@xxxxxx>]

Hello,

RAQ2

I always receive above error message when trying to send a message to an
account on one of my servers. The email is undelieverable and getting back
to sender along with the error.

The strange this is:

virtual site settings are ok
DNS settings are ok
email server settings are ok (domain is in the "accept email from these
hosts" list)

Any ideas? I'm clueless. :(
