How do I configure DKIM?

How do I configure DKIM for my domain?

To properly configure and manage DKIM (DomainKeys Identified Mail) in the Secure Exchanges online portal, it is essential to follow specific steps to ensure the security and authenticity of sent emails. Here is a detailed guide.

Step 1: Access to domain management

  1. Log in to the Secure Exchanges online portal.
  2. In the left-hand menu, under "Domains", click "Manage your domains".

Step 2: SPF configuration verification

Before enabling SPF validation (Sender Policy Framework), you must configure DKIM.

Step 3: Creating the DKIM selector

  1. In the "Actions" column for your domain, click the outlined shield, marked 3 below. The complete procedure is also shown there.

  • 1. The green checkmark: the domain validation status.
  • 2. The solid shield: the SPF configuration.
  • 3. The outlined shield: the DKIM configuration.
  • 4. The trash can: removes the domain from your organization.
2. The selector is a unique key that you will need to enter into your DNS settings.

Step 4: DNS configuration

Add the DKIM selector as a key and the DKIM record as a value in your domain's DNS records.

Step 5: DKIM activation

Once the DNS is updated, validate and activate the DKIM selector in the portal.

Note: This step is crucial for DKIM to be fully operational.

Step 6: DKIM key rotation

To increase security, you can consider rotating the DKIM key after a certain period of time. To do this, click the DKIM shield again in the "Actions" column for your domain.

You will see this page there:

  • 1. The active DKIM selector, along with the full selector including your domain.
  • 2. The DKIM key to publish in your DNS.
  • 3. The "Create new rotation selector" button.
  • 4. The "Deactivate DKIM" button.

You can click on "Create a new rotation selector" and follow the same steps seen previously.


Step 7: Disabling DKIM

If necessary, you can disable DKIM by clicking the "Disable DKIM" button; to do this, SPF validation (Sender Policy Framework) must be disabled beforehand.

Note: This action is reversible, and you can re-enable DKIM at any time.

Important tips

  • Domain validation: Make sure the domain validation is complete before proceeding with DKIM activation.
  • DNS propagation delay: DNS changes can take up to 48 hours to fully propagate. Check that all settings are correct before considering the process complete.
  • DKIM key management: Regular management and rotation of DKIM keys is recommended to maintain optimal security.

This detailed procedure will help you configure and manage DKIM for your domain through Secure Exchanges, increasing the security of your email communications.
