Benefits of Using DMARC Failure Reports

Unlike DMARC Aggregate Reports, DMARC Failure Reports are generated instantly, which is one of the key benefits of this report type. Forensic reports are sent to the URI configured on your website’s DMARC policy under the “ruf” tag.

By receiving DMARC Failure Reports, domain owners can identify malicious actors attempting to use their domain for spoofing or phishing and take appropriate action.

DMARC Forensic Reports provide valuable insights into how a domain is used, allowing domain owners to take steps to protect their domain from abuse. This can help improve email deliverability, reduce email spoofing and phishing, and protect their domain reputation.

Frequently Asked Questions

What Is a DMARC Failure (Forensic) Report?

DMARC Failure Reports are essentially the copy of your email sent when SPF and DKIM alignment fails. They provide details into the reasons behind DMARC failures, which help discover the root cause, track email fraud and phishing attempts, and improve your email security posture.

DMARC Failure Reporting includes details about the type of failure:

Infrastructure problems
Lack of verification from the ESP
Various other reasons

DMARC Failure (Forensic) Reports are much more detailed than DMARC Aggregate reports, as they show a sample of an email message that failed SPF, DKIM, or DMARC tests.

Failure Reports offer specific information about each email you sent from your domain, detailing everything that goes wrong with the message and why it was rejected.

DMARC Failure (Forensic) Reports contain all the information about individual email messages, including:

Sending source IP
"From" and "To" email addresses
Email subject line
SPF and DKIM authentication results
Received time
Email Header

In-depth analysis of the emails that failed DMARC
Information on the root cause of the failure

How To Analyze DMARC Failure Reports?

To analyze DMARC Failure Reports, you will need to look at the data provided in the report to identify the following:

Emails that failed DMARC authentication
The source IP address
The domain
The DKIM signature used
Other information

From there, you can use this data to identify the source of the failed messages and determine why the messages are failing. Some common issues that can lead to DMARC failures include using the wrong DKIM signature, misconfigured SPF records, or misusing a domain name associated with the sending IP address.

Additionally, you can use the data from the Failure Report to look for any malicious activity or spam emails from your domain.

What To Do With DMARC Failure Reports?

With DMARC Failure Reports, domain owners can identify potential sources of domain spoofing or email phishing and take appropriate actions to mitigate these threats.

Failure Reports can also help identify misconfigurations in the sender's email authentication settings, such as incorrect SPF or DKIM records, and help ensure proper authentication for all future emails.

How Often Are DMARC Failure Reports Sent?

DMARC Failure Reports are generated and sent immediately after the Mail Receiver detects a DMARC failure. Depending on the number of emails sent by your domain, you may receive multiple Failure Reports per day or even per hour.

What Information Is Included in DMARC Forensic Reports?

DMARC Forensic Reports contain detailed information about emails that have failed DMARC authentication, including:

Email subject line
Email Header information (i.e., To and From)
The IP address of the sending server
SPF, DKIM, and DMARC authentication result

Additionally, the DMARC Failure Report may include the body of the message and other data that may help troubleshoot why the message failed authentication.

DMARC Aggregate Report vs. DMARC Forensic Report: Which Is Better?

DMARC Aggregate Reports and Forensic Reports serve different purposes. Saying that one is better than the other wouldn’t be entirely correct.

DMARC XML Aggregate Reports are an overview of the authentication status of all emails sent from a domain. In contrast, the Forensic Reports provide detailed information about each email that failed DMARC validation.

Depending on your organization's needs, one or the other may be more suitable. Generally, the Aggregate Report is better for getting an overall picture of your domain's performance. The Forensic Report is better for analyzing individual emails that fail DMARC authentication.
