DomainKeys & DKIM (Linux cPanel accounts)
DomainKeys & DKIM
DomainKeys Identified Mail (DKIM) is the successor to DomainKeys (DK). This is a feature that helps you to prevent spam by verifying the sender of incoming emails, and checking for modifications to the original message.
We fully support 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 a number of ways.
How to Enable DKIM for Incoming and Outgoing Mail:
1) Log in to cPanel.
2) In the Mail section, click Email Authentication icon.
3) Under DKIM -> click Enable.
