Domain-based Message Authentication, Reporting, and Conformance (DMARC) work with Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to authenticate mail senders and ensure that destination email systems trust messages sent from your domain. Implementing DMARC with SPF and DKIM provides additional protection against spoofing and phishing emails. DMARC helps to receive mail systems to determine what to do with messages sent from your domain that fail SPF or DKIM checks. 

End users and companies suffer from the high volume of spam and phishing on the Internet. Over the years several methods have been introduced to try and identify when mail ‘from’ for example, ‘IRS.GOV’ is legitimate or not. 


• These mechanisms work in isolation from each other. 

• Each receiver makes unique decisions to evaluate the results. 

• The legitimate domain owner (e.g. IRS) never gets any feedback. 

DMARC attempts to address this by providing coordinated and tested methods for: 

1.    Domain owners to: 

• Signal that they are using email authentication (SPF/ DKIM) 

• Provide an email address to gather feedback on messages using their domain – legitimate or otherwise. 

• A policy to apply to the messages that fail authentication (report, quarantine or reject) 

2.    Email receivers to: 

• Be certain that the sending domain is using email authentication. 

• Consistently evaluate SPF and DKIM along with what the end-user sees in their inbox. 

• Determine the domain owner’s preference (report, quarantine, or reject) for messages that do not pass authentication checks. 

• Provide the domain owner with feedback on messages using their domain.
