Email authentication helps prevent spam. The options below attempt to equip email messages with verifiable information so that the nature of incoming and outgoing messages can be detected automatically.

Enabling these features should reduce the number of failed delivery notifications you receive when spammers forge messages from your domain(s). These features also work to prevent spammers from forging messages that claim to be from your domain(s).

DKIM

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.

SPF

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.

Getting Started

cPanel Email Authentication Settings

1) Click on 'Authentication' in the Email section of cPanel shown above.

2) Click 'Enable' for DKIM and SPF.

This is all you need to do and the system will take care of the rest. You'll see your screen look like this image below.
