The
purpose of DKIM is to check that an email is really from the domain or
sender that it said it was sent from and if it has been altered in any
way in transit. DKIM, like SPF, enables a specific aspect of the email sending process to be authenticated from your domain.
Specifically, DKIM (DomainKeys Identified Mail), provides a foundation for distinguishing legitimate mail. A DKIM signature is placed in the header of emails sent by StackCP's mail servers, so that the receiving mail server can then validate the signature using a public cryptographic key (2048 bit). It's added as a 'TXT record' in the 'Manage DNS' section for the domain name.
DKIM is not a guarantee that all emails will be
delivered. Instead, it provides the receiving mail server with
further information so it can make a more informed decision on the best
way to handle the email.
How to add a DKIM record through StackCP:
2. Head to 'Shared Hosting' and click 'Manage StackCP'
3. Inside StackCP click the Search Icons and enter DKIM.
4. Click on "DomainKeys" icon
The signature will be added immediately to emails sent from the
mailboxes under the domain selected. Our system will automatically add a
DNS record into the Manage DNS. Please wait a while for that record to become active and begin working on your email.
