Sorry for the delay I was on a site.

The Primary and Secondary DNSs didn't change.  The Primary is on the GW 
system and the secondary is local (the mail server as a slave to the GW 
DNS system).  If I ping a FQDN I see that the resolution to IP is 
there.  So I don't think it is the DNS resolution or am I missing something?
