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).
