I am having trouble sending external mail using Exchange 2000 SMTP.
I have a completely fresh install of Win2000 with SP2, and Exchange 2000. Using Outlook 2000 as mail client.
I have setup the default SMTP Virtual server with a smart host reference (my ISP mail server, which worked when I was using ex5.5) and the same reference for my fully qualified domain name. The rest is vanilla setup.
When I send a message I immediately get a NDR from exchange no internet traffic to speak of. Like this : The e-mail system was unable to deliver the message, but did not report a specific reason.
I have tracked the messages and it goes through 4 steps before the NDR step. The last step being Message submitted to Categorizer.
Basically the messages aren't ending up in the SMTP queue. The domain of the email that I was sending to is there but on enumerating the messages, there are none.
No internet traffic happens after the send so it's halting when it hits the queue.
Does anyone have any ideas on this. I am at a complete loss.
I have setup diagnostic logging on everything and there are no warnings or errors that appear in the app event log.
