    Have you run the tests at testexchangeconnectivity.com - in general the detailed information puts you on the right track
    From the message above, it looks like an open relay test, which should fail

      That looks like the MXToolBox SMTP test. Your Exchange server passed the test as it refused to relay. How is that related to your problem?

          Pretty self explanatory message. The account does not exist on the server.

          Please use a valid email account to test.

                This is EXPECTED behaviour (you have been told this twice already) Unless you want to be a spammers paradise, open relays should FAIL - i.e. the open relay test above will pass.

                Can you explain what your actual problem is instead of posting reams of test results.

                    Glad you found the issue. You should remove all the google MX records if you want your email to be sent to mail.mawadagroup.com.

                    Are you doing a migration from GoogleApps to Exchange? Are you just testing things out?
                    Regards,
