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 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 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 'Email Delivery' in the Email section of cPanel shown above.

2) Next click on 'Manage' next to the domain that you want to enable DKIM and SPF for.

3) On the next screen, click 'Enable' for DKIM and SPF. If the records are already added, this screen will tell you whether they are valid or if there is an error instead.

Records can be manually modified under 'Zone Editor' found in the 'Domains' section of cPanel or you can click 'customize' on the page mentioned in step 3 above.

Note: Creating an invalid record can prevent your email from being properly delivered to your recipients. If you have questions, please submit a ticket to us for Tech Support.

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.
