Oh no, please

postconf -n
postconf -Mf
doveconf -n

Make sure your MUA is setup to make a STARTTLS connection to Postfix's 
submission port. I don't see that in your logs.

See https://doc.dovecot.org/admin_manual/logging/ for debugging your 
connections to dovecot.

I still see "warning: dict_nis_init: NIS domain name not set - NIS 
lookups disabled" in your pasted logs.

I'm sorry, here:
postconf -n https://pastebin.com/UQQhieMy
postconf -Mf https://pastebin.com/AHEUSkfQ
doveconf -n https://pastebin.com/s7DVY9XW

This is the configuration. Afaik thats also the correct port for SMTP.
I've also checked that all the ports are open on the server (via 
netstat): https://pastebin.com/tY6rSi8y
I have (currently) no firewall installed so there aren't any ports 
blocked either.
Since it's in an internal network there is also no ISP which can block 
any ports (and I've also already added a few mailboxes from other 
sources without any problems).

It's only there bc this logs are made before I made the change in config 
regarding this.
Can't find it in any newer entries after restarting postfix.
