What is DMARC?
Domain-based Message Authentication, Reporting & Conformance (DMARC) is an email authentication protocol designed to combat email spoofing and protect users from phishing attacks. It works by providing a mechanism for domain owners to establish policies that specify how messages claiming to be from their domain should be handled if they fail SPF and DKIM checks.

DMARC consists of three primary components:
- Alignment - Ensures that the domain of the sender matches the domain in the SPF and DKIM checks.
- Policy - The domain owner sets a policy that instructs email receivers on how to handle unauthenticated messages.
- Reporting - DMARC provides two types of reports, Aggregate and Forensic, that offer valuable insight into email authentication performance and potential threats.
DMARC Forensic Report
A DMARC forensic report, also known as a failure report, provides detailed information about individual messages that fail DMARC checks. These reports are triggered when messages do not align with the domain owner's DMARC policies. Forensic reports are beneficial as they help domain owners understand the specifics of unauthorized email activity, enabling them to identify and remediate potential security threats.
Components of a DMARC Forensic Report
Forensic reports contain important information about the email in question, including:
- Message headers with authentication results as observed by the receiving email server.
- The reason for DMARC authentication failure.
- The original message source IP address and domain.
- The sending domain's DMARC policy.
- Indication whether the message was blocked, quarantined, or delivered according to the domain owner's DMARC policy.
Benefits of DMARC Forensic Reports
Utilizing DMARC forensic reports offers numerous benefits to domain owners and security professionals, such as:
- Increased visibility into email traffic originating from their domain, enabling them to detect potential security threats.
- Identification of malicious activities, such as email spoofing.
- Information required to improve email authentication, leading to better deliverability and trust among recipients.
- Enhanced email security by quickly identifying and rectifying configuration errors that lead to unauthorized email activity.
DMARC Forensic Report Example:
Imagine that your organization recently implemented DMARC to protect your brand and customers from email spoofing and phishing attacks. One day, you receive a DMARC forensic report signaling that an email failed the DMARC authentication.
The report reveals that the message originated from a suspicious IP address and failed the SPF check. This information helps you assess the situation and determine that a malicious attacker sent a spoofed email in an attempt to compromise sensitive information from your customers.
Armed with this knowledge, you trace the origin of the attack and tighten your email security further by refining your DMARC policy. This quick response prevents potential harm to your customers and reputational damage to your brand.
Staying vigilant against email-based threats is invaluable in today's digital environment. By using DMARC forensic reports to gain deeper insight into your email authentication performance, you can effectively reduce the risk of phishing attacks and ensure a safer inbox for your users. Don't let your brand fall victim to email fraud – start implementing and benefiting from DMARC today!
