What is DMARC?
DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that builds on SPF and DKIM. It tells receiving mail servers what to do with emails that fail authentication — monitor them, send them to spam, or reject them entirely.
Strongest protection — failing emails are blocked
Failing emails are sent to spam folder
Monitor mode — no action taken on failures
