To be more clear, by hardcoded addresses I meant local delivery. Postfix has local accounts which exist on the machine as local users (eg. root@mailserver) and virtual domains where there is no local user backed to it. Your question didn’t state which type of transport you’re using so I provided both.
When setting up my smart host for my virtual domain I also found the Debian included instructions helpful https://sources.debian.org/src/postfix/3.5.23-0%2Bdeb11u1/debian/README.Debian/ Someone with more Postfix experience will correct me if wrong.
