Sorry if this is the wrong subforum for my question.
I'm currently trying to make some changes to my system which requires changes to /etc/postfix/master.cf and /etc/postfix/main.cf
The configs already state in the header that changes there will be overwritten and it seems like postfix doesn't read .local files.
What other options do I have to change the files without doing the changes over and over again after upgrades?
I'm running Debian 10 with i-MSCP 1.5.3-maintenance (21.10.19) in case thats important.
