Having an issue with multiple domains on exchange

I should add that when I ping the domain in question, I do the get IP address to resolve, to the FQDN ping, but get no ping response.  This is not a worry as the firewall onsite is not set to return pings

Update on the issue.  I RDP's to the clients site and set the firewall to allow ping returns.  When I ping the two funtional domains (in terms of receiving email) I get the ping reponses back correctly. When I ping the non-functional FQDN, I do get a resolution to the correct IP, but I get a timeout on the responses.

Here is a tracert to one of the functional mail domains.
