Also known as: Domain-based Message Authentication Reporting and Conformance
Last updated August 8, 2026
Definition
DMARC builds on SPF and DKIM to tell receivers how to handle mail that fails authentication and to report abuse back to domain owners.
Real-World Example
A domain with a strict DMARC policy asks providers to reject forged messages that pretend to be from that domain.
