To access the Email Deliverability tool, connect to your cPanel interface and click on"Email Deliverability" in the"E-mail" section.

DKIM configuration

This section allows you to manage the DKIM record for a domain, and to check the sender and integrity of a message. In addition, it allows the messaging system to check that spammers have not modified an incoming message while it is in transit. Finally, this key is used to check that emails received by your domain actually come from the specified domain.

To install a DKIM record correctly, your server must be the authoritative name server

[tips_warning]Important :

Exposing your DKIM private key can be a security problem. If other people obtain your key, they will be able to sign emails pretending to be you. For this reason, only provide the DKIM key to people you trust.[/tips]

SPF configuration

This section allows you to manage the SPF registration of a domain. This zone checks that messages sent by your domains come from a listed and authorised server. If there are problems with this DNS Zone, a correct SPF configuration will appear in the "Suggested SPF record" section. This section also allows you to perform the following actions:

Customise an SPF record

You can use this interface to customise the SPF record recommended by the system for your domain. The interface displays the domain's current SPF name and value in the "SPF record (Zone TXT)" section of your DNS Zones, if this exists, and the system's recommendations in the "Suggested SPF record" section.

Here you can modify the following parameters:

Feature	Tool description
Domain setting (1)	This section lets you define the hosts or MX servers authorised to send emails from your domain name: Additional Hosts: Additional hosts authorised by the system to send emails. Click on "Add a New Host (+a) item" to add a new SPF record. Additional MX Servers: MX entries authorised to send emails from your domains. Click on "Add a New (+mx) item" to add a new MX entry to the domain's SPF record.
IP Address Setting (2)	This section allows you to add additional IP address blocks to the SPF record for your domain name.
Additionnal Setting (3)	This section allows you to modify additional SPF record settings: Include List (INCLUDE): Additional domain to include in your SPF settings. Use this setting to send an email from another service such as Mailchimp. Exclude All Other Hosts ("-all" Entry): Exclude all hosts that other SPF mechanisms do not allow.

Conclusion

You are now able to identify any problems related to DKIM or SPF configuration on your domain. Note that modifying your configuration may cause problems when sending emails. For this reason, it is preferable to only modify the SPF configuration if this has been requested by another service provider such as Mailchimp or if you have encountered an error when sending an email.
