Postfix wont start due to permissions, but permissions look correct.

I'm following the install steps from here to set up the email server of CentOS 7:

Status postfix.service output:

sudo systemctl -l status postfix.service
[sudo] password for tenraek: 
● postfix.service - Postfix Mail Transport Agent

Permissions match what I see on my CentOS7 install where Postfix is running.

Is it possible you're running SELinux and need to check the directory context related to that?
Run "sestatus" to see how SELinux. If not "disabled" your issue is likely the context settings.

Just an observation.
I don't see the file for which permission was denied in the ls output:
[CODE /usr/sbin/postconf: fatal: close /etc/postfix/ Permission denied[/CODE]
