Okay found the issue. The fax server is attempting to send mail out as ‘uucp’. My SMTP server is rejecting that as a valid sender.

Seems to me the fax server should be pulling the same SMTP info as the rest of the system, particularly the sender email account, or be able to specify the sender email address in Global Fax Settings or Fax Devices.
So please address this email issue, and please explain the apparent redundancy of the Inbound Route destination settings and the “proper” way to do it.0
