Understanding DMARC

Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an email authentication protocol that helps protect your brand reputation and customers from email phishing and spoofing. Email phishing is a fraudulent attempt by malicious actors to obtain sensitive information or data by posing as a reputable source through email. Spoofing is when a hacker assumes the identity of a genuine sender to trick victims into opening and acting on an email.

Setting Up DMARC for Your Domain

To set up DMARC, you must first verify that the domain authority is under your control. Domain authority is the ability to control the domain name system records for your domain.

  • Step 1: Publish DMARC Record

    • The first step in setting up DMARC is to publish a DMARC record in the DNS. This record sets the policy for email receivers to follow when they encounter an email message from your domain. You can do this by adding a new TXT record to your domain’s DNS, which contains the DMARC policy settings. Make sure to specify the subdomains you want to include in your DMARC policy.

  • Step 2: Set the DMARC Policy

    • You can set three levels of DMARC policy: None, Quarantine, and Reject.

  • None: This policy allows email receivers to monitor email messages that fail DMARC checks but will not reject them.
  • Quarantine: This policy instructs the email receivers to treat a message that fails DMARC as suspicious and send it to the user’s spam folder.
  • Reject: This policy tells the email receivers to block any message that fails DMARC checks.

    • It is recommended to start with the “None” policy before moving to “Quarantine” and “Reject” policies to minimize the impact on your email deliverability.

    DMARC Reporting and Monitoring

    DMARC reporting is a critical feature that helps you monitor and analyze your email authentication status. It provides valuable insights into the effectiveness of your DMARC policy and helps identify any unauthorized use of your domain name and email servers.

    You can use DMARC reporting to:

  • Detect and prevent email phishing and spoofing attacks.
  • Improve email deliverability by identifying and fixing any issues with your email infrastructure.
  • Gain visibility into all emails sent on behalf of your domain, including legitimate and unauthorized emails.

    • DMARC Best Practices

    Here are some best practices to follow when setting up and managing your DMARC record:

  • Start with the “None” policy before moving to “Quarantine” and “Reject” policies.
  • Make sure to include all subdomains in your DMARC policy.
  • Monitor your DMARC reports regularly to identify unauthorized use of your domain name and email servers.
  • Correct any issues or errors identified in your DMARC reports promptly.
  • Test your DMARC policy using email testing tools before publishing it in your DNS.

    • Conclusion

    Setting up DMARC for your email domain can significantly improve your email security and reduce the risk of unauthorized use of your domain name and email servers. By using DMARC, you can protect your customers from email phishing and spoofing and gain valuable insights into your email infrastructure’s health and performance.
