But the way I understand it, he does not want to deliver to any host
anywhere except the local machine and users to one other machine. He does
not want to be able to send email to anywhere else.

The way I would do it is like this:

Set up exim as a standalone system UNABLE to deliver internet mail. This
is an option in eximconfig and then add the one router listed above for
LAN delivery to the one host. Any other mail will not find a capable
router and will fail.
