I apologise. That was not my intent. I attempted to locate the relevant log entries and was unsuccessful. Due to the simple fact I was looking in the wrong place. I could not find the entries in the log file so what I had I posted here. My original question was to the effect: What does 501 blah blah mean? Debugging the problem sort of grew out the initial inquiry. I posted what I had because I did not know what type of error I was looking for and thus what might cause it. What is self-evident to you is somewhat obscure for me. It never crossed my mind that email was being sent out from any other server than our public host because we block port 25 outgoing for all but a limited number of hosts. Unfortunately, the web application in question is our fax service and while that application does indeed permit mailing faxes it had not been configured to do so. That host is also on the list of permitted addresses to use TCP25 out because it belongs to our comm block segment. Postfix is also installed on that server to enable administrative email. The web fax configuration default sends SMTP to 127.0.0.1, the user thought that it would simpler to forward a fax via email, and the rest is history. It was only after I confronted the individual with the evidence that traffic was in fact moving to our client that the truth came out. Sincerely, -- *** E-Mail is NOT a SECURE channel *** James B.
