Add SPF and Domainkeys in cPanel

If you have a cPanel based server, adding an SPF record or domain keys entries for domains are so much easier than manually entering them.
cPanel provides the following scripts/commands to help us through this task:

# /usr/local/cpanel/bin/domain_keys_installer

# /usr/local/cpanel/bin/spf_installer

Note:: This would add the records for all domains under this cPanel account. Meaning for all Addon domains too.
