I am perplexed at this error message when someone tries to send a email to our Exchange server. 1/4 of their employee's can send email and the other 3 get this bounce back. ORDB has not been around since 2006. DNS and RDNS is setup correctly on the receiving side and the wspharr domain is the only domain that is having a problem. I am running Groupshield 6.0.1 with a Sonicwall firewall. I can telnet through to the Exchange server through port 25. If someone has seen this, please let me know.
The message cannot be delivered due to a configuration error on the server. Please contact your Administrator.
