DKIM Configuration Procedure

1. Access to Domain Management:
  1. Log in to the Secure Exchanges online portal .
  2. Navigate to the "Domain Management" option.
2. SPF Configuration Verification:
  1. Before enabling SPF (Sender Policy Framework) validation , you must configure DKIM.
3. Creating the DKIM Selector:
  1. Click on the following icon to generate a new selector. The complete procedure will also be found there.


  1. The selector is a unique key that you will need to enter into your DNS settings.
4. DNS Configuration:
  1. Add the DKIM selector as a key and the DKIM record as a value in your domain's DNS records.
5. DKIM Activation:
  1. Once the DNS is updated, validate and activate the DKIM selector in the portal.

  1. This step is crucial for DKIM to be fully operational.

  1. This action is reversible, and you can reactivate DKIM at any time.

Important Tips:

  1. Domain Validation: Ensure that domain validation is complete before proceeding with DKIM activation.
  2. DNS Propagation Time: DNS changes can take up to 48 hours to propagate fully. Verify that all configurations are correct before considering the process complete.
  3. DKIM Key Management: Regular management and rotation of DKIM keys are recommended to maintain optimal security.
