I have an exchange 2003 email server that outgoing emails do not appear to be going out.
The emails get as far as the email queue and don't get any further.
I am getting lots of messages like the following:
Message delivery to the host '220.127.116.11' failed while delivering to the remote domain 'comet.co.uk' for the following reason: The remote server did not respond to a connection attempt.
This leading me to think it might be something to do with my DNS settings, as my exchange server is also acting as a domain controller.
Incoming emails are working fine and the servers internet connetion is working fine.
