How to use this check
Enter a domain to read its DMARC record and understand whether receivers see none, quarantine or reject policy.
MailHealth reads _dmarc.domain TXT through the same bounded DNS resolver and returns only parsed tag facts.

Guide and interpretation
How to interpret the result
p=none is useful for observation, while quarantine or reject is stronger once SPF/DKIM alignment is ready.
Example
_dmarc.example.com with v=DMARC1; p=reject; rua=mailto:dmarc@example.com tells receivers to reject unauthenticated aligned failures and send aggregate reports.
Common issues and next steps
A domain may publish DMARC with p=none forever, which gives visibility but little protection.
Use reports to fix legitimate senders, then move gradually toward quarantine or reject with a pct rollout.
Methodology and limits
The free check does not collect, parse or store DMARC XML reports; report ingestion belongs in an account feature.
FAQ
Will MailHealth receive my DMARC reports?
No. Report ingestion is an account feature and is not active in the free check.
Is p=reject always safe?
No. Move to enforcement only after legitimate senders pass SPF or DKIM alignment.
