Of course there is. In fact, there are probably several ways.

This is the "closed mailing list" problem, except that you are
restricting the hosts rather than the senders. You can
(1) Put a condition on the router (using "condition" to test
$sender_host_address) so that the router is skipped when the message
comes from elsewhere. This will cause deliveries and verifies to bounce.
OR
(2) Put something in a ACL along the lines of
deny recipients = lusers@???
hosts = ! 1.2.3.0/24
OR
(3) There's probably another way...
