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 '129.35.70.45' 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.

Just to add some value. To get the MX record(s) for a domain:
nslookup
set type=MX
<domain>
e.g:
c:\>nslookup
Default Server: <your DNS>
Address: <your DNS IP>
> set type=MX
> redhat.com
Server: <your DNS>
Address: <your DNS IP>
Non-authoritative answer:
redhat.com MX preference = 10, mail exchanger = mx2.redhat.com
redhat.com MX preference = 5, mail exchanger = mx1.redhat.com
mx1.redhat.com internet address = 209.132.183.28
mx2.redhat.com internet address = 66.187.233.33
