Gmail nor any other big provider enforce the equivalent of reject_unknown_client_hostname, but many of them do enforce the equivalent of reject_unknown_reverse_client_hostname. You might use that restriction instead. It rejects quite a bit of spambot mail yet seldom rejects a legit host, and is considered a safe restriction by most sites. http://www.postfix.org/postconf.5.html#reject_unknown_reverse_client_hostname -- Noel Jones
