I understand (or I only think so) what you're saying. But it's not completely related with my problem (or I only think so). I need to reject them with my own custom error message. That's why I'm asking how to do it as I'm afraid that if I will put restriction like: smtpd_client_restrictions = reject_unknown_reverse_client_hostname, check_client_access hash:/etc/postfix/client and in /etc/postfix/client I will put: unknown REJECT 550 5.1.2. "FIX YOUR REVERSE DNS" then the client accepted by the first rule will be rejected by the second one, won't it ? As it has got PTR but no hostname. Regards, Jarek
