Is there a way to internally resolve an external domain name to a internal IP address? For a couple of applications to work both internally and externally I need to have mail.company.com resolved to an internal name/IP when connected locally.
External - company.com - Externally hosted DNS
Internal - company.local
Internally mail resolves to the internal IP while mail.company.com resolves to an external IP but never connects.
Is there a zone I can create to resolve only mail.company.com internally and pass the rest onto the external DNS?
Thanks in advance

Sure.
Create a zone called "mail.company.com", then add a Host (A) Record with a blank name pointing at the internal IP.
The blank name should make the record appear as "(same as parent folder)".
With this method you only claim authority for mail.company.com so all other records within company.com are sent to external name servers as before.
