Want to make an internal A-record for a domain not my own?

[Christoph Wagner]

Hi,

I want to resolve a host eg. www.not-my-domain.com by my internal name 
servers (because we want to reach this server via private addresses over 
an extranet link).
I am not the owner of this domain and so I do not want to configure/copy 
all public domain entries in my internal name server. I think they would 
never be complete and uptodate as I do not get them from the domain owner.
What can I do if I need to resolve this one host address via FQDN for my 
applications eg. internet browser. I do want to loose eg. the 
MX-record-definitions of the public servers of the domain owner.

Are there any solutions using bind or any other software?

Kind Regards,
Chris
