Description:
Verifies that DMARC policies are published for all domains.
Why:
Without a DMARC policy available for each domain, recipients may improperly handle SPF and DKIM failures, possibly enabling spoofed emails to reach end users' mailboxes. Publishing DMARC records at the second-level domain protects the second-level domains and all subdomains.
Configured: DMARC policies are published for all domains.
Not Configured: DMARC policies are not published for all domains.
Scoring: Contributes up to 1 point to the Posture Recommendations score.
