I don't know how to do that but I wonder why you want to. The whole point of authentication is to allow your users to get email without having to trust the system they are coming in from. If you trust the domain then just add it to mynetworks and don't bother with authentication. I suggest authentication though so that your users can get their email no matter where they are.
