Need Help - Domains being rejected

We moved our mail server yesterday and while I was updating some settings in 2 of our EFA boxes I seem to have broken something.

We have about 100 domains and 2 out of the 100 are now be rejected.

When I send an email from the command line I get "Sender address rejected: Domain not found"

One of the two domains is our primary.

We use transport maps which import the users and domains into the form "domainname.com smtp:[172.xx.xx.xx]". This has been working fine, in fact 1 of 3 EFA boxes, a backup, still runs fine using the same transport file as the other 2 boxes.

Not sure where to look. Any help is appreciated.

Got it working.

Turned out in the process of configuring changes for the moved Mail Server I had changed the DNS server as well. Used an internal that probably has split DNS.

Changed it back and all is working now.
