Numerical Code: 5.3.5
Possible Cause: Loop-back detected (server is configured to loop back on
itself).
If you have multiple SMTP virtual servers that are configured on your
Exchange server, make sure that they are serving unique incoming port and
also that the outgoing SMTP port configuration is valid to avoid looping
between local virtual servers.
Troubleshooting: Check the configuration of the server's connectors for
loops. For example, make sure that no connectors exist that have the address
space of the local organization unless you share the domain and you do not
select Use DNS to route to each address space on this connector. For
