This presumes a machine on a network with site-local addresses. The OP's machine is presumably single-attached to a network with public addresses and no external firewall. We should close this thread, the OP is long gone or in any case has the answer in hand: - Firewall rules are out of scope for Postfix. - Postfix can listen on multiple IPs, ... which supports internal-only SMTP services when the Postfix server is connected to multiple networks, or uses secondary IP addresses on a single network behind a firewall which permits external SMTP traffic only to a subset of the machine's IP addresses (or address:port combinations). -- Viktor.
