451 4.4.0 DNS query failed. The error was: SMTPSEND.DNS.NonExisten   
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?

Re: 451 4.4.0 DNS query failed. The error was: SMTPSEND.DNS.NonExi   
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
