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 business email compromise attacks, phishing emails, email scams, and other cyberthreat activities. Once a DMARC DNS entry is published, any receiving email server can authenticate the incoming email based on the instructions published by the domain owner within the DNS entry. DMARC was defined in 2015 in RFC 7489. ← Wikipedia
