What is DMARC?

DMARC or Domain-based Message Authentication Reporting and Conformance is a framework designed for 2 things:

  1. Allow the email sender to tell the receiver what to do in case of a forged email.
  2. Allow the email receiver to send back reports on the authentication checks, and the action it applied on the emails. 

Authentication Checks:

  1. SPF stands for the Sender Policy Framework. This authorizes which IP Addresses are allowed to send emails on your behalf.
  2. DKIM also is known as DomainKeys Identified Mail enables digital signatures on your outgoing emails. This helps to verify your message.

 These 2 checks are performed by the receiving mail server to verify the emails sender’s authenticity
