Hi I am using Exchange 2007 and have just installed a new edge server and
when I try to send external e-mails they get stuck in the queue (with the
above error) on the hub transport server and never seem to make it to the
edge server. The only thing I can think of is that we have something
misconfigured on the edge server because it has a dns suffix with .co.uk and
the local server is .local
Also Edge synch works, pinging between the servers, telnet. so general
general conectivity is fine. For now the firewall is also turned off until
this is resolved so that's not in the way.
Thanks

Can you lookup the MX record of the faulty domain using NSLOOKUP from the
Edge serverr?

I turns out it was a very stupid mistake. I was trying to add the .co.uk edge
server to my .local dns site once I created a .co.uk site in dns and added my
server like I should have from the start it all started working.
Thanks anyway
