Notes
To check the default webmail client that a user uses for their email box on a cPanel server, you can use the following command:
egrep "roundcube|horde" /home/*/.cpanel/nvdata/*_default_webmail_app
It will show a user, email box and default webmail app that set up by the user by default
To change the master domain for an account on a cPanel server from the command line, you can use the cPanel API WHMAPI1. Here are the steps:
– Connect to the server via SSH using your preferred terminal emulator.
– Use the following command to change the master domain for the account:
whmapi1 modifyacct user=USERNAME newdomain=newdomain.com… Read the rest
Check if an account didn’t overuse its limits

Means you mistakenly chowned your /etc folder on cPanel server
chown root: /etc
find /etc -user USERNAME -exec chown root {} \;
find /etc -group USERNAME -exec chown .root {} \;
chown named: /etc/named.conf
chown root.named /etc/named/
