PMG: postfix notification on compatibility mode

[Glowsome]

I installed PMG (LXC template available on PVE ) recently, and whenever a restart/reload is performed of postfix the following is seen in the log:

2024-09-06T23:18:31.639328+02:00 pmg postfix[1673160]: Postfix is using backwards-compatible default settings
2024-09-06T23:18:31.639808+02:00 pmg postfix[1673160]: See http://www.postfix.org/COMPATIBILITY_README.html for details
2024-09-06T23:18:31.640308+02:00 pmg postfix[1673160]: To disable backwards compatibility use "postconf compatibility_level=3.6" and "postfix reload"
2024-09-06T23:18:31.685936+02:00 pmg postfix/postfix-script[1673166]: refreshing the Postfix mail system

My question :

• Does PMG need/require to operate Postfix in 'backwards compatibility mode' ?

If this is not the case:

• can the setting to not use compatibility-mode be adopted in a fresh install/template ?
