Actually, the only thing that's needed is this:

   deny    hosts     = +home_net
           !authenticated = *
          set acl_c_denied_by_mail = yes
          set acl_c_dbm_message = Papers, please.


That blocks both 25 and 587 unless the user is authenticated.
Submissions to the local domain work fine. Just outgoing email needs an
authenticated user.

That's pretty neat.
