About DMARC Lookup

DMARC tells receivers what to do when SPF/DKIM alignment fails: monitor (p=none), quarantine or reject. A healthy setup usually moves from p=none (with rua reporting) toward quarantine/reject once sources are known.

This tool fetches the DMARC TXT record, highlights the policy, and shows related SPF/BIMI checks.

Frequently asked questions

Where is the DMARC record published?

At _dmarc.yourdomain.com as a TXT record beginning with v=DMARC1.

Is p=none enough?

p=none is useful for monitoring, but it does not tell receivers to block forged mail. Aim for quarantine or reject once legitimate sources pass SPF/DKIM.
