In attempting to fix my Postfix situation on my CentOS 7, CyberPanel Community setup, I uninstalled and reinstalled Postfix via terminal (“yum install…”). The result is Postfix no longer works for sending emails. I imagine I need default configuration files (master.cf and main.cf?) to fix this. How can I get the default Postfix configuration for CyberPanel back?
mv /etc/postfix/main.cf.rpmsave /etc/postfix/main.cf
mv /etc/postfix/master.cf.rpmsave /etc/postfix/master.cf
systemctl restart postfix
