Thanks, that's a useful example to try.

I could also TELNET to port 25 on 127.0.0.1 to confirm there is an SMTP 
server accepting connections...

BTW I'm not a Python programmer but I have been looking at a book to pick

like a pause and press a key to continue. How would I do that?

I think my problem is more than likely related to a misconfigured DNS
