Make perfect sense. I just wasn't sensible about it. I will do that.
Thanks for all the help.

ExampleA.com is on an external DNS. Website and mail server are behind a
firewall with NAT on a local LAN. Internet looking for exampleA.com gets
resolution from external DNS. Fine. Any thing on that LAN, if there is
no
zone for exampleA.com on the internal DNS server, will be sent to the
external DNS server. They will then receive the public IP address, which
they will not reach because the firewall will say you want this, it is
on
the local LAN, go there.
Therefore, you have to use Split DNS. What you have to do is duplicate
the
exampleA.com zone on the internal DNS server except use the internal IP
addresses.

Correct.
