DMARC Resources and Information

May 25, 2017

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol, which includes a reporting function that allows senders and receivers to improve and monitor protection of the domain from fraudulent email. Implementation of DMARC will prevent Spammers from spoofing the “From” address on mail messages.  Depending on the DMARC policy settings, any mail messages originating from an unauthorized mail server will be either quarantined or rejected.

DMARC builds upon the existing authentication protocols: Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM).
