We have internal DNS servers that will override the A record for selected hosts. Example mail.pdinc.us will have a different internal ip than external. 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.
