DMARC stands for Domain-based Message Authentication, Reporting and Conformance. DMARC is a protocol used for email validation, policy and reporting. DMARC enables the owner of an email domain to indicate what should be done with non-authentic emails using this domain name. DMARC also provides reporting capabilities, so that legitimate and non-legitimate outgoing email flows are documented for analysis and for detecting potential abuse.
