Adding New DKIM Selector to your Domain

To manually add a new DKIM selector to your domain:

  1. On the DKIM Management page, click the domain to which you need to add a selector.
  2. Click Insert Selector next to the Instructions at the top of the page.
  3. In the pop-up that appears, enter a unique selector name in the Selector field.
  4. In the Type CNAME/TXT field, select the required option from the list.

    • CNAME: URL to another domain

    • TXT: DKIM public key

  5. In the Value field, enter the value relevant to the selected Type CNAME/TXT.
  6. (Optional) In the Notes field, enter the description as required.
  7. In the Service field, enter the service that the selector is used for.
  8. (Optional) Select the t=s? checkbox to support only exact domain signing.

    If you select this checkbox, the DKIM signature is valid only for the exact domain in the record.

    For example, if you select this checkbox and the domain is example.com, any email sent from sales.example.com will not pass DKIM validation using the existing key for example.com. To enable DKIM for sales.example.com, you must add a separate DKIM record.

  9. Click OK.
