Introduction to DMARC
Welcome to the comprehensive world of DMARC (Domain-based Message Authentication, Reporting, and Conformance). DMARC builds upon SPF and DKIM, providing guidelines for handling unauthenticated emails.
What is DMARC?
DMARC is the comprehensive framework that builds upon SPF and DKIM. It provides guidelines for handling unauthenticated emails.
How Does DMARC Work?
- Policy Enforcement: Domain owners publish DMARC records specifying their desired policy (e.g., “none,” “quarantine,” or “reject”). These policies dictate how receivers should handle unauthenticated emails.
- Reporting and Monitoring: DMARC enables domain owners to receive reports on email authentication failures, providing insights into unauthorized email activity.
- Impact on Deliverability: DMARC ensures consistent email authentication across domains, prevents phishing attacks, and improves overall email security.
Why DMARC Is Crucial
- Strengthen Security: DMARC validates senders consistently across domains.
- Reduce Phishing Risks: Unauthorized emails won’t deceive recipients.
- Enhance Trust: Consistent authentication builds confidence.
