What is DMARC?
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that helps protect your domain from email spoofing and phishing attacks. It builds on SPF and DKIM to provide a way for domain owners to:
- Specify how to handle emails that fail authentication
- Receive reports about email authentication results
- Gradually enforce stricter policies without disrupting legitimate email
DMARC Policy Levels
- p=none — Monitor mode. No action is taken on failing emails, but you receive reports.
- p=quarantine — Suspicious emails are sent to spam/junk folders.
- p=reject — Failing emails are rejected entirely and never delivered.
Example DMARC Record
v=DMARC1; p=reject; rua=mailto:[email protected]; pct=100
Why DMARC Matters
Without DMARC, attackers can send emails that appear to come from your domain. This can damage your brand reputation, lead to phishing attacks against your customers, and affect email deliverability. Major email providers like Google and Yahoo now require DMARC for bulk senders.
