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.

WHY!
Email was invented a gazillion years ago and it's still a shiit experience to setup on linux. Just give me ONE complete package!!
nooo i need to get postfix, dovecot, spamassassain mailscanner, antivirus, opendmarc, opendkim, dovecot-managesieve dovecot-sieve, roundcube, database, webserver and then i still have to configure everything and setup certs, spf, dnssec, dkimkeys on the domains, domains, mailboxes, deny weak certs etc.

I know the whole do one thing and do that one thing well but how about you just be a mailserver and do that ONE thing well without me needing to putting all of the puzzle pieces together myself! I don't want to waste time setting all this shit up. and don't even get me started on symantec and live.com and their blocking!
