proxy_interfaces

Possible values:

IP addresses

Default:

(null)

When a Postfix server is running on an internal network behind a proxy or NAT device, and it serves as the backup MX host for a domain, it’s possible to get mail delivery loops when the primary MX host is down. The proxy_interfaces specifies a list of network interface addresses that receive mail via a proxy device. Postfix avoids mail loops with listed interfaces.

Example:

proxy_interfaces = 192.168.15.23
