What is DMARC?
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that builds upon SPF and DKIM. It helps protect your domain from email spoofing, phishing attacks, and business email compromise by specifying how to handle emails that fail authentication checks.
DMARC Policy Options Explained
p=none: Monitor mode - no action taken on failed emails. p=quarantine: Failed emails sent to spam/junk folders. p=reject: Failed emails are completely blocked. Start with p=none to monitor, then gradually increase strictness.
Frequently Asked Questions
Should I start with p=none or a stricter policy?
Always start with p=none to monitor your email authentication without affecting delivery. Collect reports for 2-4 weeks, then gradually move to p=quarantine and finally p=reject once you're confident your legitimate emails pass authentication.
Do I need SPF and DKIM before implementing DMARC?
Yes, DMARC requires either SPF or DKIM (preferably both) to be properly configured first. DMARC checks if emails pass SPF and/or DKIM authentication and are properly aligned with your domain.
What are DMARC reports and why are they important?
DMARC reports show you who is sending emails using your domain and whether they pass or fail authentication. These reports help you identify legitimate email sources, detect spoofing attempts, and fine-tune your email authentication setup.
