About This DMARC Checker
Mailvovo checks the DMARC record published for a domain, determines the effective policy using DMARC policy discovery, reviews alignment settings, reporting destinations, and available policy evidence. A valid DNS record does not prove that a specific email passed DMARC.
Frequently Asked Questions
A DMARC record is a DNS policy that tells receivers how to handle messages that do not align with SPF or DKIM, and where to send reports.
p=none is a valid monitoring policy. It requests reporting without asking receivers to quarantine or reject messages solely because of DMARC policy.
The published record is the DNS policy found at a policy domain. The effective policy is the policy calculated for the domain being checked, including inheritance where applicable.
When a direct subdomain policy is absent, DMARC policy discovery can find an applicable organizational-domain policy.
rua defines aggregate-report destinations; ruf defines failure-report destinations when receivers support them.
No. DNS configuration does not prove real message alignment or receiver behavior. That requires message-level evidence.
