DMARC Report Formats: XML and JSON

Table of Contents

DMARC reports are crucial for understanding your email authentication performance and identifying any potential issues that might impact email deliverability. These reports are generated by receiving mail servers and provide valuable insights into how your emails are being authenticated and treated.

DMARC reports come in two primary formats:

  • XML (Extensible Markup Language): This format is the original and widely supported format for DMARC reports. It uses a hierarchical structure with tags and attributes to represent the data. XML reports are more verbose and can be challenging to parse manually.
  • JSON (JavaScript Object Notation): This format is more modern and offers a simpler, more human-readable representation of DMARC report data. JSON reports use key-value pairs and nested objects to organize information. This makes them easier to analyze and integrate with data processing tools.

Understanding DMARC Report Elements

Both XML and JSON DMARC reports include similar data elements, providing information about the following:

  • Report Metadata: This section contains details about the report itself, including the reporting domain, the reporting period, and the report's creation date.
  • Policy: This section summarizes the sender's DMARC policy, including the enforcement mode (none, quarantine, reject), the alignment policy (strict, relaxed, or loose), and the DMARC record's rua and ruf values.
  • Records: This is the heart of the DMARC report, containing individual records for each email that has been authenticated. Each record provides details like:
    • The sender's email address
    • The email's domain
    • Authentication results (SPF and DKIM)
    • The receiving mail server's policy applied to the message
    • The reason for any rejection or quarantine

Troubleshooting DMARC Authentication Problems

DMARC reporting provides valuable insights into your email authentication performance, highlighting areas that need attention and improvement. While the reports provide a wealth of information, deciphering them and identifying the root causes of authentication failures can be challenging. This section will equip you with the knowledge and strategies to effectively troubleshoot DMARC authentication issues, leading to enhanced email deliverability and a better sender reputation.

Understanding Common Authentication Errors

DMARC reports are like a diagnostic tool for your email authentication strategy. They highlight areas where your emails fail to pass authentication checks, leading to potential deliverability issues. Common error types you might encounter in your DMARC reports include:

  • SPF Mismatch: This error occurs when the sending server's IP address doesn't match the allowed senders listed in your SPF record. For example, if your SPF record specifies that only your company's primary email server is authorized to send emails, but your email marketing platform is also sending emails on your behalf, you'll likely encounter an SPF mismatch.
  • DKIM Failure: DKIM failures happen when the digital signature generated by your email server doesn't match the one included in the email header. This could occur due to incorrect configuration of your DKIM record, compromised server, or issues with your email sending process.
  • Domain Alignment Issues: Domain alignment errors occur when your SPF and DKIM records don't align correctly with your DMARC policy. For instance, if your DMARC policy is set to p=quarantine, but your SPF record doesn't explicitly permit the sending server, you'll receive a domain alignment issue in your DMARC reports.

Strategies for Effective Troubleshooting

Pinpointing the root cause of DMARC authentication failures requires a systematic approach. Here's a step-by-step guide to help you effectively troubleshoot these issues:

  1. Review Your DMARC Policy: Start by examining your current DMARC policy. Ensure your policy aligns with your desired authentication outcome. A p=none policy simply reports on authentication results, while p=quarantine will quarantine emails that fail authentication, and p=reject will outright reject them. If your DMARC policy is too restrictive, it could be causing legitimate emails to be rejected.
  2. Analyze DMARC Reports: Carefully review your DMARC reports for patterns and trends. Look for the most frequent error types, affected domains, sending servers, and rejection reasons. This will provide valuable insights into the root causes of authentication failures. Consider using DMARC aggregator tools like to simplify the analysis process. These tools offer automated reporting, visualization, and alert features.
  3. Verify SPF Record: Double-check your SPF record to ensure it's correctly configured and includes all authorized sending servers. Use a tool like SPF Record Checker to validate your SPF record and identify potential issues. Make sure to include your email marketing platform, if you use one, in your SPF record.
  4. Inspect DKIM Record: Ensure your DKIM record is correctly set up and properly aligned with your DMARC policy. Verify the selector and public key are correct, and that the DKIM record is properly signed. Use a tool like DKIM Validator to test your DKIM record for errors.
  5. Address Alignment Issues: If your DMARC policy doesn't align with your SPF and DKIM records, correct the mismatches. Ensure your SPF record permits the sending server specified in your DKIM record. Make sure your DMARC policy reflects the desired authentication actions for your organization.
  6. Investigate Sending Servers: Examine the sending servers identified in your DMARC reports. If you notice a specific server is causing frequent authentication failures, investigate its configuration and ensure it's correctly configured to meet DMARC requirements.
  7. Monitor and Adjust: Continuously monitor your DMARC reports to track the effectiveness of your troubleshooting efforts. If you continue to see authentication errors, adjust your SPF and DKIM records or DMARC policy accordingly.

Case Study: Identifying and Resolving a DKIM Failure

Let's explore a real-world example of troubleshooting a DMARC authentication issue. Imagine you receive a DMARC report indicating a high number of DKIM failures. The report shows that emails sent from your company's marketing platform are consistently failing the DKIM check. After further investigation, you discover that the marketing platform's DKIM record is configured with a different selector than the one used in your emails. By correcting the selector mismatch in the marketing platform's DKIM record, you resolve the authentication issue and ensure that your emails pass the DKIM check.

Best Practices for Preventing Future Issues

Implementing effective preventative measures can significantly reduce the likelihood of encountering DMARC authentication issues in the future. Here are some key best practices to consider:

  • Consistent DMARC Implementation: Ensure a consistent DMARC policy across all your domains and sending servers. This will minimize confusion and prevent authentication conflicts.
