smtp_fallback_relay

By default, mail is returned to the sender when a destination is not found, and delivery is deferred when a destination is unreachable.

The fallback relays must be SMTP destinations. Specify a domain, host, host:port, :port, or :port; the form turns off MX lookups. If you specify multiple SMTP destinations, Postfix will try them in the specified order.
