How to add DKIM and SPF records for your domain in cPanel – updated July 31st, 2020

DKIM and SPF are two mechanisms that allow you to prevent SPAM email messages. Also, they will improve your email delivery rates. You can easily enable them in cPanel.

DKIM is a means of verifying incoming email. It ensures that incoming messages are unmodified and are from the sender from whom they claim to be. This feature works to prevent incoming spam messages.

The SPF system allows you to specify servers and IP addresses that are authorized to send mail from your domain(s). This feature works to prevent outgoing spam messages.
