An example of an email authentication report is a DMARC report. It offers details on communications that pass or fail DMARC analysis. It is intended to provide email domain owners with knowledge on who and how their domains are being utilized.

DMARC, which stands for “Domain-based Message Authentication, Reporting, and Conformance,” is an email authentication protocol that is built on top of two other protocols: Sender Policy Framework (SPF) and Domain-Keys Identified Mail (DKIM). The goal of DMARC is to give email domain owners a way to protect their domains from unauthorized use, such as phishing and email spoofing.

Explaining DMARC report.

When an email message is received, the receiving mail server compares it against the DMARC policy issued by the domain owner. The message is sent to the recipient’s inbox if the DMARC evaluation is successful. Nevertheless, depending on the DMARC policy and setup, the receiving mail server may reject, quarantine, or deliver the message to the recipient’s spam folder if it passes DMARC review.

Email domain owners receive DMARC reports from mail servers, which provide vital details about the messages that pass or fail DMARC analysis. This reporting system is a crucial component of DMARC, since it enables domain owners to monitor who is using their domains and how.

A DMARC report is an XML file that contains information about messages that have been sent to a mail server. The report includes the following information:

  • The email domain that the message was sent from.
  • The IP address of the server that sent the message.
  • The results of the SPF and DKIM evaluation.
  • The action taken by the receiving mail server (delivered, rejected, quarantined).
  • Additional information, such as the message headers and the authenticated identity of the sender.

Here’s an example of DMARC Report:

v=DMARC1; p=reject; rua=mailto:dmarc-reports@emailauth.io

A DMARC record comprises a single line of plain text. It contains a series of DMARC tags and values separated by semicolons. Certain tags are required, while others are not. Domain owners can instruct the receiving servers what to do when an incoming message fails authentication by establishing a DMARC policy. When configuring the DMARC record, the “p” tag is where the DMARC policy specifies the action to be taken. It is important to note that only the “v” and “p” tags need to be mentioned in sequence; all other tags can be put in any order.

Importance of DMARC Reports for Email Domain Owners.

  • Provides valuable insights into email authentication failures and potential security threats.

  • Allows domain owners to monitor and improve their email authentication policies over time.
  • Helps improve email deliverability and reduce the risk of emails being marked as spam or junk.
  • Increases email security and defends against email fraud, phishing, and spoofing.
  • Facilitates compliance with industry standards and regulations such as GDPR, HIPAA, and CCPA.

A DMARC report is a useful tool for owners of email domains who want to protect their domains against unauthorized use. These reports give domain owners access to information on who and how their domains are being used. by disclosing details on messages that pass or fail DMARC assessment. Using DMARC may greatly improve email security and protect against email fraud. It’s critical to regularly analyze DMARC reports. As it works with your email service provider to properly set up your DMARC policy. In general, DMARC is a reliable and crucial standard for protecting email systems and email domains.
