We have internal DNS servers that will override the A record

This has always been a fine way to handle it as the zone
files are for
that specific host, and there have never been subdomains before.
Now we want to just override the MX records for pdinc.us
without having
to merge or manage all the records for every entry/subdoamin in the zone file for pdinc.us.
Any ideas/questions?
We have been doing this with djbdns for years. The tinydns data files permit suffixes (suffices?) based on the querying IP address to return information specific to that IP range. That is a request for support@example.com from an ip in 192.168.0.0/16 may return the private LAN address while one from the outside world the public IP, perhaps on a different server.
Sounds like what we could use, but we are deeply entrenched in bind. Secondly is it available from the upstream provider?
