Should I configure both the internal and external to be mail.prodatamgmt.com or should I go with:

External: mail.prodatamgmt.com

Internal: exchange2013.ad.prodatamgmt.com

James,

personally, I would always try to go with as few namespaces as possible (in your case: one) which inevitably leads to split-horizon DNS. If you don't feel bad about doing split-horizon DNS, go with it. Makes obtaining SSL certificates easier, among other things.

I was hoping that would be the case, cj.  Thank you.

We use ZoneEdit for our external DNS hosting provider and, of course, all our internal Domain Controllers are also DNS servers.  So we can use mail.prodatamgmt.com for both internal and external.

ZoneEdit will point to our static IP assigned by our internet service provider, and the domain controllers will point to the internal IP address of the exchange server.

Thank you!
