You would not use this: /etc/postfix/main.cf: mynetworks = hash:/etc/postfix/access Instead, you could use this: /etc/postfix/main.cf: smtpd_client_restrictions = check_client_access cidr:/etc/postfix/client_access.cidr /etc/postfix/client_access.cidr: # Order of rules is important. 192.168.1.0/24 OK 10.0.0.0/8 OK # These wildcard patterns must be last. 0.0.0.0/0 reject ::/0 reject See also; "man cidr_table".
