About the DMARC Check
DMARC Check locates and parses a domain's DMARC record, a TXT record published at the _dmarc subdomain and starting with v=DMARC1. It interprets the policy (none, quarantine, or reject), the alignment modes, and the reporting addresses for aggregate and forensic reports. DMARC builds on SPF and DKIM to tell receivers how to handle mail that fails authentication.
How to use
- Enter the domain whose DMARC policy you want to check.
- Run the check to read the TXT record at _dmarc.yourdomain.
- Review the policy, alignment settings, and rua reporting addresses.
Frequently asked questions
- Where is the DMARC record published?
- DMARC is a TXT record at the _dmarc subdomain, for example _dmarc.example.com, and begins with v=DMARC1.
- What does the DMARC policy tag do?
- The p tag sets the action for failing mail: none monitors only, quarantine sends it to spam, and reject blocks it outright.
- What are the rua and ruf addresses?
- rua receives aggregate XML reports summarizing authentication results, while ruf receives forensic reports about individual failures, where supported.
