While working with adding a website to apache on my server something
caused a blanket resetting of all file permissions on the server to
apache:apache. I have most of the server running again but my mail
services is another story. I have configured vmail on a Postfix with
Dovecot and mariadb install. What I need is help with reestablishing the
correct file and folder permissions that dovecot uses. The following is
my configuration;
# OS: Linux 4.18.0-147.3.1.el8_1.x86_64 x86_64 CentOS Linux release

Keep your system updated! Current kernel is
4.18.0-240.1.1.el8_3.x86_64
and CentOS 8.3.2011 is the current OS minor release.
# Dovecot version# 2.2.36 (1f10bfa63)
Why is that this ancient version of dovecot? CentOS 8 ships
https://centos.pkgs.org/8/centos-appstream-x86_64/dovecot-2.3.8-4.el8.x86_64.rpm.html
on the x86_64 platform.

I really need help with this, thanks.
For dovecot and other packages installed through install / dnf use
rpm --setperms <packagename>
rpm --setugids <packagename>
For /var/vmail you have specified vmail:vmail. Same for /home/vmail.
