There is no meaning to the words 'authenticated,' 'unauthenticated,' or 'login' if SASL is disabled. The only 'login' possible in SMTP in Postfix is via SASL. It is not possible to "spoof" an authentication system that is not present. So, in a sense, this is a known and logically obvious behavior. -- Bill Cole _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
