Do you have anonymous ticked in the Default Receive connector properties?
if not please tick , restart Transport service and try.

Do a SMTP test from http://mxtoolbox.com/diagnostic.aspx

A few questions:

1. Is your exchange box virtualized?
2. Do you have any devices/network such as spam filtering appliances/applications?
3. Do you have issues internally sending and receiving emails?

Did you try recreating the relay connector?
