Certainly doable. I have had this running for some years now. I also
have mail.myself.dk resolving to an internal address if I am on my
internal network and to an external address if I am outside my network.
I use bind with two views and dhcpd for internal addresses updating one
Setup was almost automatic.

No improvements come from shouting:
"MALE BOVINE MANURE!!!"
