Todays issue appeared during a migration from SBS 2003 to SBS 2008. The Xerox copier was configured to send incomming faxes to a shared mailbox. However, it was no longer performing this, offering only 'transmit failed'.
After not being able to get anything further from the copier as to what this issue was, I installed Network Montior and reviewed traffic from the copier.
Trawling through the SMTP traffic highlighted that Exchange 2007 was rejecting mail with a 530 5.7.1 Client was not authenticated.
I rechecked the Exchange hub transport to ensure that relaying was permitted, which it was. Digging deeper, the Default connector did not have anonymous authentication ticked, which is why this was failing.
