What is DMARC?
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a technological standard that is designed to prevent email spoofing. Email spoofing is a method used by cybercriminals to send emails from a fake sender’s address. Such emails are usually phishing emails or spam emails that are designed to trick the recipients into clicking on malicious links or downloading malware.
How does DMARC work?
DMARC works by combining two widely used authentication technologies: Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM). SPF enables the recipient to verify if an email message was sent from an authorized sender. DKIM ensures the integrity of the received email message by comparing the original signature added by the sender with the signature on the received message. DMARC acts as a policy engine that verifies if both SPF and DKIM authentication checks pass or fail, and decides how to handle the message based on the policy applied by the domain owner.
