If I remember well: appeareance of 'hosts' acl condition *always* causes
reverse dns lookup and causes some kind of failure if the address can't
be verified. But I'm NOT sure.

You could accept the messages from authenticated clients first.

    accept  authenticated = *
    deny    !verify = reverse_host_lookup
