This has little to do with DNS, and there's nothing obviously wrong. The
router has the routable IP address and is forwarding incoming port 25
tcp connections to the real mail server using NAT.  

As far as the internet side is concerned your entire network has to
look like a single server, so the mailserver has to pretend to be
running on the router, and announce itself as mail.whitneybaptist.org.

You'll probably need to pass your outgoing mail through another mail
server to avoid its being rejected though.
