DMARC
DMARC is the acronym for Domain-based Message Authentication, Reporting and Conformance.
Domain-based Message Authentication, Reporting and Conformance
An email authentication protocol designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing. The purpose and primary outcome of implementing DMARC is to protect a domain from being used in email phishing attacks, email scams, and other cyber threat activities. Key components of DMARC include:
- Linking the sender’s identity to the domain: DMARC ensures that the sender’s identity aligns with the visible sender’s address, enhancing the email’s legitimacy.
- Policy Implementation: DMARC allows domain owners to specify how an email receiver should handle emails that don’t pass DMARC authentication. This is expressed as a policy that can tell the receiver to do nothing, quarantine the message, or reject it outright.
- Reporting: It provides a mechanism for email receivers to report to the sender about messages that pass or fail DMARC evaluation. These reports are crucial for organizations to monitor and adjust email authentication practices.
DMARC is vital for maintaining the integrity and reliability of email communication. By implementing DMARC, businesses can protect their brand reputation, prevent email fraud, and increase the deliverability of their marketing emails, ensuring that these emails reach their intended audience.
