dns_cpmail.sh

#!/bin/bash
#
# Name: dns_cpmail
# Version: 1.0
# By MarcelFox
#
#	HOW TO WORK WITH?
# 	As 'root' and in a cPanel server run:
#	  bash dns_cpmail.sh
#
# WHAT DOES?
#	Check for DMARC, DKIM & SPF of a primary domain 
#	of a user direct from his $HOME. If none of those
# entries (or one of those), are not found, dns_cpamail
# will adjust, check the zone and reload the services
# rndc and named.
#
#	WHY ROCKS?
#	It's flawless so far, and it gives you links to
# check for the entries on MXToolBox, which is a relief!
# It's also pretty, with colors and styles :)
#
