DMARC RUF Reports: Understanding Failures and How to Improve Email Security

downward arrow destroying the floor

As email security becomes more crucial for businesses, DMARC has emerged as one of the most effective protocols for preventing email fraud and phishing attacks. DMARC (Domain-based Message Authentication, Reporting & Conformance) enables email domain owners to publish policies that specify which mechanisms are allowed to send email on behalf of their domain. It works in conjunction with SPF (Sender Policy Framework) and DKIM (Domain-Keys Identified Mail) to authenticate email messages sent from a domain.

However, despite the strength of DMARC, there is still a possibility of email fraud, and this is where DMARC Failure Reports, also known as forensic reports, come in. In this blog, we will discuss what DMARC Failure Reports are, how they work, and how they can help protect your organization against email fraud.

What are DMARC Failure Reports?

DMARC Failure Reports are forensic reports (RUF) that provide detailed information about email messages that have failed DMARC authentication. They allow email domain owners to gain insight into what types of messages are failing DMARC authentication and why. By analysing DMARC Failure Reports, email domain owners can identify patterns and trends in failed messages and take appropriate action to prevent email fraud.

How Does DMARC Failure Reports Work?

When an email message fails DMARC authentication, the email receiver sends a DMARC Failure Report back to the email domain owner. This report contains a detailed analysis of the failed message, including the reasons for the failure, the IP addresses of the sending and receiving servers, and other relevant information.

DMARC Failure Reports are generated for messages that fail DMARC checks, which can occur for several reasons. For example, the message may not have passed SPF or DKIM checks, or the message may have been modified in transit. By analysing DMARC Failure Reports, email domain owners can gain insight into the specific reasons for failed messages and take appropriate action to prevent future email fraud.

How Can DMARC Failure Reports Help Protect Your Organization?

DMARC Failure Reports can be used to identify patterns and trends in failed messages, which can help organizations take proactive steps to prevent email fraud. By analysing these reports, email domain owners can identify the source of the failed messages and take action to prevent future incidents.

For example, an email domain owner might use DMARC Failure Reports to identify a pattern of failed messages originating from a specific IP address. They can then take action to block messages from that IP address or report it to the relevant authorities. Additionally, DMARC Failure Reports can help email domain owners identify fraudulent messages that are trying to impersonate their domain, which can help prevent their customers from falling victim to phishing attacks.

How to Access DMARC Failure Reports?

DMARC Failure Reports are generated and sent to email domain owners automatically by email receivers. However, accessing and analysing these reports can be a challenge, especially for organizations that receive a large volume of email. This is where third-party solutions like EmailAuth’s DMARC analysing feature come in.

EmailAuth’s DMARC analysing feature provides a user-friendly interface for accessing and analysing DMARC Failure Reports. It allows email domain owners to quickly identify failed messages, analyse the reasons for failure, and take appropriate action to prevent email fraud. With EmailAuth’s DMARC analysing feature, organizations can gain valuable insights into their email traffic and protect their customers against phishing attacks.

DMARC Failure Reports are an essential tool for organizations looking to protect their email domains from fraud and phishing attacks. By providing detailed information about failed messages, DMARC Failure Reports enable email domain owners to take proactive steps to prevent future incidents. 

To sum it up, DMARC Failure Reports offer valuable insights into email authentication failures and help organizations take proactive steps to prevent email fraud. Accessing and analysing these reports can be a challenge, but with EmailAuth’s DMARC analysing feature, it’s made easy.
