DMARC (Domain-based Message Authentication, Reporting, & Conformance) is an email authentication protocol that builds on SPF and DKIM to protect your domain from email spoofing and phishing attacks. Setting up a DMARC record for your domain enhances your email security and provides visibility into how your emails are handled by receiving mail servers. This guide will walk you through the steps to set up a DMARC record for your domain.

Why DMARC is Important

DMARC helps to:

  • Prevent email spoofing and phishing attacks by verifying that incoming messages are from legitimate senders.
  • Improve email deliverability by ensuring that recipient servers trust your emails.
  • Provide reports that offer insights into your email authentication performance and potential issues.

  1. Understand DMARC Policies:
    • None (p=none): Monitors your email traffic without affecting delivery.
    • Quarantine (p=quarantine): Mark emails that fail DMARC as spam or move them to the junk folder.
    • Reject (p=reject): Blocks emails that fail DMARC from being delivered.
  2. Log in to your domain’s DNS management:
    • Re-access your domain.
  3. Create a DMARC TXT Record:
    • Add a new TXT record in your DNS settings.
    • In the name/host field, enter. _dmarc.
    • In the value/data field, enter the DMARC policy. For example, copy codev=DMARC1; p=none; rua=mailto:dmarc-reports@yourdomain.com; ruf=mailto:dmarc-reports@yourdomain.com; pct=100 Here:
      • v=DMARC1Specifies the DMARC version.
      • p=none Sets the DMARC policy (none, quarantine, or reject).
      • rua=mailto:dmarc-reports@yourdomain.com is the email address to receive aggregate reports.
      • ruf=mailto:dmarc-reports@yourdomain.com is the email address to receive forensic reports.
      • pct=100 Indicates that the policy applies to 100% of emails.
  4. Save the DMARC Record:
    • Save the TXT record in your DNS settings.
    • It may take up to 48 hours for the DNS changes to propagate.
  5. Monitor DMARC Reports:
    • Regularly check the email addresses specified for DMARC reports.
    • Analyze the reports to understand your email authentication performance and adjust your SPF and DKIM settings.

Example DMARC Record Setup

For a domain hosted with GoDaddy, here’s how you would set up a DMARC record:

  1. Log in to your GoDaddy account.
  2. Go to the DNS Management page for your domain.
  3. Click “Add” to create a new TXT record.
  4. In the name/host field, enter. _dmarc.
  5. In the value/data field, enter the copy code.v=DMARC1; p=quarantine; rua=mailto:dmarc-reports@yourdomain.com; ruf=mailto:dmarc-reports@yourdomain.com; pct=100
  6. Save the record.
