Hello,

Using an internal access only postfix mail server to relay mail, however after adding new subnets to our network I'll need to add those network address ranges and, also, a single host on yet another subnet. Where in postfix or in the main.cf can I add the new address ranges and what is the correct syntax?

Your question is unclear. What is the role of these networks? If they are to be allowed to use the server to relay mails, then they have to appear in a check that permits the relaying before reject_unauth_destination is called. example: /etc/postfix/main.cf: mynetworks = 192.168.1.0/24, 10.10.0.0/16, 192.168.2.1 smtpd_recipient_restrictions = permit_mynetworks check_client_access cidr:/etc/postfix/clients_allowed_relay reject_unauth_destination /etc/postfix/clients_allowed_relay: 1.2.3.4 OK All of the mentioned ip addresses are allowed to relay. If you want Postfix to listen on these networks then you need to define inet_interfaces. -- Sandy List replies only please!
