Agreed, the way we do this here is in the check rcpt ACL:

  deny    condition      = ${if eq {$interface_port}{587} {yes}{no} }
          !authenticated = *
          message        = Relay not permitted, authentication is
required to use submission port


Sorry, I don't remember who I got that from, probably somewhere here
on the mailing list.

All truth passes through three stages. First, it is ridiculed. Second,
it is violently opposed. Third, it is accepted as being self-evident.
