DMARC Validation
DMARC Record Checker - Validate DMARC Policy
Check and validate DMARC (Domain-based Message Authentication) records for email security.
How It Works
This tool looks up the DMARC record at _dmarc.domain.com and validates its syntax. It checks the policy (none, quarantine, reject), reporting addresses, and alignment settings.
Understanding Results
Results show the DMARC policy, parsed tags (p, rua, ruf, pct, etc.), and validation status. A properly configured DMARC record helps protect your domain from email spoofing and provides visibility into email authentication.
