Network tool
DMARC Checker
Inspect the DMARC policy and reporting settings published for a domain.
What this result means
DMARC builds on SPF and/or DKIM and requires alignment with the visible From domain. Its policy requests receiver handling; it does not guarantee delivery or eliminate all abuse.
How this check works
p=none requests monitoring without enforcement, p=quarantine requests suspicious failing mail be quarantined, and p=reject requests rejection. adkim and aspf control DKIM and SPF alignment; absent values default to relaxed. Aggregate (rua) and failure (ruf) reporting support varies by receiver and is never contacted by this tool.
