DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication protocol. It is 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 business email compromise attacks, phishing emails, email scams and other cyber threat activities. Once the DMARC DNS entry is published, any receiving email server can authenticate incoming emails on the basis of the instructions published by the domain owner within the DNS entry. If the email passes the authentication, it can be trusted and will be delivered. If the email fails the check, depending on the instructions held within the DMARC record the email will either be delivered, quarantined or rejected.
