DMARC, or Domain-based Message Authentication, Reporting, and Conformance, is an email authentication protocol that aims to prevent email fraud and phishing attacks by providing sender authentication. It ensures that emails are sent from a legitimate source and not from attackers using fake email addresses to trick recipients into disclosing personal information. DMARC offers a standardized mechanism for email receivers to verify the authenticity of incoming emails and reject unauthenticated emails to protect end-users from fraudulent emails.

After DMARC policies have been implemented and validated, it is important to verify and monitor them regularly to ensure that they are working effectively. Verification should be done by conducting frequent checks to ensure that the DMARC policies are successfully passing email authentication and that the email paths are correctly configured. DMARC reports can be used to identify any issues and fine-tune the DMARC configuration to enhance email authentication.
DMARC tags help identify the DKIM and SPF alignment status of an email message. DMARC tags are added to the DMARC record and provide additional information about how to handle messages which are considered authentic, failed authentication, or suspicious. Here are the common DMARC tags:
