Understanding DMARC Reports

Table of Contents

DMARC reports are the heart of your DMARC implementation. They provide valuable insights into the health of your email sending infrastructure and help you understand how your DMARC policies are being enforced. These reports give you a detailed view of the email traffic that is being sent on your behalf, allowing you to identify and address any potential issues.

There are two main types of DMARC reports:

  • Aggregate Reports: These reports summarize the overall performance of your DMARC policy over a specified time period. They provide information on the number of emails sent, the number of emails that passed or failed DMARC checks, and the percentage of emails that were aligned with your DMARC policy. Think of these as high-level summaries of your email traffic.
  • Forensic Reports: These reports provide detailed information about individual emails that failed DMARC checks. This includes the sender's email address, the recipient's email address, the reason for the failure, and the time of the failure. You can use these reports to investigate individual email spoofing attempts and take steps to prevent future attacks.

Why are DMARC reports important?

DMARC reports are important for several reasons:

  • They help you identify and address potential email spoofing attempts. By monitoring your DMARC reports, you can identify emails that are being sent on your behalf without your permission. This allows you to take steps to prevent future spoofing attempts, such as reporting spoofers to their email providers or blocking their emails at the source.
  • They help you improve your email deliverability. A high percentage of emails that fail DMARC checks are likely to be flagged as spam. By addressing the issues that are causing these failures, you can improve the deliverability of your legitimate emails.
  • They help you build trust with your recipients. DMARC helps to protect your brand reputation by ensuring that only legitimate emails from your domain are delivered to recipients. This increases the trust that your recipients have in your brand and helps to ensure that your emails are not treated as spam.

How to read DMARC reports

DMARC reports can be a bit confusing at first, but they are not as complex as they might seem. Here's a quick guide to help you understand the basics:

  • The report's summary: This provides a high-level overview of the report's contents, including the reporting period, the number of emails that passed or failed DMARC checks, and the percentage of emails that were aligned with your DMARC policy.

  • The report's details: This section provides detailed information about individual emails that passed or failed DMARC checks. The details typically include the sender's email address, the recipient's email address, the reason for the failure, and the time of the failure.
  • The report's policy: This section shows the DMARC policy that is being enforced for your domain. This includes the policy's p and sp values.

Analyzing DMARC reports

Once you have a basic understanding of how to read DMARC reports, you can start to analyze the data they contain to identify and address any potential issues. Here are a few things to look for:

  • The percentage of emails that failed DMARC checks. If you see a high percentage of failures, it indicates that there are potential problems with your email sending infrastructure. You should investigate these failures to determine the cause and take steps to address the issue.
  • The reasons for the failures. DMARC reports will include information on why emails failed DMARC checks. This could be due to a number of reasons, including misconfigured SPF or DKIM records, or unauthorized senders using your domain. [INSERT_IMAGE - DMARC report showing the reasons for DMARC failures]

Interpreting DMARC Metrics

Once you have a DMARC policy in place and you are receiving reports, the next step is to interpret the metrics within those reports to understand how your policy is working. These metrics can provide valuable information about your email infrastructure and the effectiveness of your DMARC policy in preventing spoofing attempts.

Key DMARC Metrics

DMARC reports provide two primary metrics: p (policy) and sp (speaks for). Both metrics are represented as percentages, and understanding their meaning is crucial for effective DMARC monitoring.

  • p (policy): This metric indicates the percentage of emails that passed your DMARC policy. A high p score indicates that a significant portion of your emails are aligned with your DMARC policy and are less likely to be flagged as spoofed.
  • sp (speaks for): This metric indicates the percentage of emails that passed DMARC alignment checks but originated from a sender domain that you explicitly authorized. A high sp score is desirable as it indicates that most emails coming from your domain are truly authorized by you.

Example:

Imagine your organization receives 100 emails. Of those 100 emails, 80 pass the DMARC alignment checks. However, only 60 of those 80 emails are actually authorized by your organization.

  • In this case, your p score would be 80% (80/100). This means 80% of the emails passed your DMARC policy.
  • Your sp score would be 75% (60/80). This means 75% of the emails that passed your DMARC policy were actually authorized by your organization.

Analyzing DMARC Metrics

The interpretation of DMARC metrics involves considering various factors:

  • Policy Alignment: A high p score indicates that your email sending infrastructure aligns well with your DMARC policy. If your p score is low, it suggests that a significant portion of your emails are not adhering to your DMARC policy, which could be due to misconfigured senders or unauthorized email sources.
  • Authorized Email: A high sp score indicates that most of your emails are truly authorized by you. A low sp score may suggest that unauthorized senders are spoofing your domain, resulting in potential deliverability issues and reputation damage.
  • Trends: It's essential to monitor the trends in both p and sp scores over time. Any sudden drops in these metrics may indicate potential security issues or changes in your email infrastructure that require immediate attention.

DMARC Reports: The Backbone of Monitoring

DMARC reports are critical for understanding how your policy is working and for identifying potential issues. There are two main types of DMARC reports:

  • Aggregate Reports: These reports provide a summary of your DMARC policy enforcement for a specific period. Aggregate reports provide insights into overall policy alignment, unauthorized senders, and potential spoofing attempts. [INSERT_IMAGE - A graphical representation of a DMARC aggregate report]
  • Forensic Reports: These reports provide detailed information about specific email messages that failed your DMARC policy. Forensic reports can help you investigate individual instances of spoofing and understand the root cause of the problem.
