SMTP does not include the concept of *asking* a client to
authenticate - there is no challenge except in response to certain
types of AUTH command. The server advertises support for
authentication, and the client decides whether to use it or not.
You need to use a deny statement in an ACL (probably acl_check_rcpt)
to refuse messages from hosts that choose not to authenticate, for
example:
deny message = Authentication requried to send mail
!authenticated = *
This would make sense in an outbound-only server, of course.
