A step-by-step guide on “How to Publish a DMARC Record with Cloudflare”

Publishing a DMARC record with Cloudflare involves a few straightforward steps. Here’s a step-by-step guide:

  1. Log In to Your Cloudflare Account:
    • Visit the Cloudflare website and log in to your Cloudflare account.
  2. Select Your Domain:
    • From the Cloudflare dashboard, choose the domain for which you want to publish a DMARC record.
  3. Access DNS Settings:
    • Navigate to the “DNS” section in your Cloudflare account. This is where you manage your domain’s DNS records.
  4. Create a DMARC Record:
    • Click on the “Add Record” or “Create Record” button, typically located near the existing DNS records.
  5. Fill in the DMARC Record Details:
    • For the DMARC record, you’ll need to provide the following information:
      • Name (or Hostname): Enter “_dmarc” (note the underscore).
      • Type: Choose “TXT” from the record type options.
      • TTL (Time to Live): Set the TTL to your preference (e.g., 1 hour or as desired).
      • Data (or Value): Here, enter your DMARC policy. A typical DMARC record might look like this: “v=DMARC1; p=quarantine; rua=mailto:dmarc@example.com; ruf=mailto:ruf.dmarc@example.com; fo=1″
  6. Save the Record:
    • After entering the required information, save the record to publish it in your DNS settings.
  7. Verify the DMARC Record:
    • It may take some time for the DMARC record to propagate. You can use a DMARC record checker tool or Cloudflare’s DNS lookup feature to verify the record’s publication.
  8. Monitor and Adjust:
    • Regularly check your DMARC reports and adjust your DMARC policy as needed to improve email authentication and security.

Remember that the specific steps may vary slightly within the Cloudflare interface, so consult Cloudflare’s documentation or support if you encounter any issues.
