DomainKeys and DKIM

DomainKeys Identified Mail (DKIM) is the successor to DomainKeys (DK). It is a feature that helps to prevent spam by verifying the sender of incoming emails and checking for modifications to the original message.

It is recommended that everyone begin using DKIM instead of the older DK. Our servers are compatible with DKIM and implement the newer version.

cPanel

Currently, HostGator fully supports the DKIM outgoing authentication specification, which is available with version 11.32 (or later) of cPanel/WHM. As of version 11.32, cPanel & WHM's existing DK implementation was converted to DKIM and extended in many ways.

How to Enable DKIM in cPanel

1. Log in to cPanel.
2. In the Email section, click the Email Deliverability icon. 

   

3. Navigate to the  Manage button of the domain you will be modifying.

   

4. On the next page, scroll down and click Install the Suggested Record Button.

   

Plesk

Currently, HostGator fully supports the DKIM outgoing authentication specification. Users with Windows shared hosting plans should contact us via phone or chat with the domain name(s) that DKIM should be applied to.

Users with dedicated servers may enable DKIM as follows:

• Windows Dedicated Server - MailEnable
