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.
