DMARC Is Changing. Is Your Domain Ready?

DMARC has moved beyond being a DNS record that you publish once and forget. RFC 9989, published by the IETF in 2026, updates the DMARC specification and replaces the earlier RFC 7489 and RFC 9091 documents. At the same time, major mailbox providers continue to enforce email authentication requirements for bulk senders.

A properly configured DMARC record helps receiving systems determine what to do with messages that fail DMARC evaluation and gives domain owners visibility into how their domain is being used. But checking whether a record merely exists is not enough. You also need to understand the published policy, reporting destinations, subdomain policy, SPF and DKIM alignment settings, percentage controls, and whether the record contains configuration issues or outdated elements.

That is why I built the Advanced DMARC Record Analyzer — a live, read-only DNS analysis tool that reads the published DMARC record and turns the raw record into structured findings and DNS evidence instead of simply telling you “DMARC found.”

{
  "status": "ok",
  "service": "ai-discovery-builder",
  "tool": "dmarc_analyze",
  "analysis": {
    "domain": "example.com",
    "lookupName": "_dmarc.example.com",
    "record": "v=DMARC1; p=reject",
    "tags": { "v": "DMARC1", "p": "reject" },
    "findings": [{
      "code": "DMARC_REJECT",
      "severity": "info",
      "message": "The DMARC policy is p=reject."
    }],
    "evidence": {
      "source": "cloudflare-dns-json",
      "query": "_dmarc.example.com",
      "recordFound": true
    }
  }
}

Important: The analyzer reports the DMARC policy published in DNS and applies deterministic checks to the observed record. A DNS record check alone does not prove that every legitimate sending source passes SPF/DKIM authentication or alignment.
