I have do what you asked but im sorry to say that this has not worked....
i also noticed this the server gets a email like this...
Final-Recipient: rfc822; email@example.com
Diagnostic-Code: X-Postfix; mail for tracshosting.com loops back to myself
Also part of the server message i get this....
WARNING: service not running (server: tracs.tracshosting.com, port: 10000)!
