N e v e r, fucking e v e r chmod/ chown permissions recursive on the linux /etc folder❗

I did yesterday (, because I am fucking dumb and know little about linux systems) and got the result today. My whole mailserver wasn't working.
After fucking tons of googling and searching and log-digging I found that postfix and opendkim require specific permissions on their respective folders and files.

After changing a fucking amount of permissions on those fucking files the fucking mailserver worked and I can send and receive mails, now. 😤😤😤

What a torture. Lesson learned. Never will repeat this mistake.
