How to Set Up and Implement DMARC Email Security


Domain-based Message Authentication, Reporting and Conformance (DMARC) is an increasingly important approach for helping ensure the integrity of email coming from a given domain.

Unfortunately, DMARC is not turned on by default for every domain, at every web host or every email server. DMARC requires organizations and email administrators to configure and set up policies. While DMARC is not the default for email servers, adoption is now growing, thanks to adoption by the U.S. government and enterprises around the world.
