DMARC Compliance and Its Best Practices 1

What is DMARC?

DMARC (Domain-based Message Authentication, Reporting and Conformance) is a tool used to authenticate email messages to protect the organization from phishing attacks and email-based fraud. DMARC allows organizations to define policies to prevent unauthorized parties from using their domain names to send fraudulent emails to their customers or employees. When an email fails DMARC, it enables the sender domain to specify how receivers handle it.

Why is DMARC important?

DMARC is essential because it enhances email security and protects an organization’s reputation. It helps to maintain the credibility of the domain by ensuring that only authorized users send emails from it. DMARC compliance reduces the number of fraudulent emails that enter employees or customers’ inboxes, thus preventing them from becoming victims of phishing. Additionally, DMARC helps email providers recognize legitimate emails from authorized senders, making it less likely for those emails to end up in the recipient’s spam folder.

How DMARC Works

DMARC works through a three-tier system. The first tier involves the sender’s domain creating DMARC records, which inform receiving domains how they should handle inbound messages from unauthorized domains. The second tier is where the receiving domain checks if incoming emails comply with DMARC policies defined by the sending domain. The third tier is the feedback loop, where the receiving domain relays authentication and policy information back to the sender domain.

Best Practices for DMARC Compliance

Below are some of the best practices that organizations can implement to be DMARC compliant:

  • Monitor and analyze DMARC reports: Use DMARC reports to monitor email traffic and find any phishing attempts and vulnerabilities.
  • Use SPF and DKIM: DMARC builds on SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) mechanisms, which verify the sender of the email by authenticating the domain that is used to send the message.
  • Start with a monitor-only DMARC policy: Configure a DMARC policy that allows all emails to pass and generates a report on messages that fail authentication instead of blocking them.
  • Use a third-party email provider: Outsource email services to a third party and allow DMARC policy to enforce that all authorized domains send emails only via them.
  • Consistent email domain: Use a single domain for all email addresses, this ensures that no two different domains send emails, preventing confusion and phishing attempts.
  • Conclusion

    All in all, DMARC is a useful tool to enhance email security and protect an organization’s reputation. By following the best practices for DMARC compliance, organizations can have greater control over inbound emails and ensure that only authorized users can send emails from the domain. DMARC improves email deliverability and helps organizations prevent phishing attacks that can harm their customers and employees. With DMARC, businesses can rest assured that their email system is secure and free from fraudulent activities. Want to learn more about the subject covered?
