There is a solution to this, but its rather kludgy.

You can configure your domain as a virtual domain on the outer box and
put in all valid users as virtual users mapped to users on the internal
box. This way, the outer box would accept mail only for valid users.

Problem would only be when you add new users when you would have to add
entries for new users on both the boxes.

Kludgy, but would work.
