What is a DMARC XML Report?
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication policy that builds on SPF and DKIM. When enabled, mail receivers send aggregate reports (RUA) as XML files — either directly to your inbox or to a reporting service. These reports list every IP address that sent email claiming to be from your domain, how many messages were sent, and whether they passed SPF and DKIM checks.
How to Use This Tool
- Download the DMARC report attached to an email (usually a
.zipor.gzfile containing an.xmlfile). - Drag and drop the file above, or click Select File.
- The tool parses the XML entirely in your browser and shows you a clear breakdown of the results.
You can also upload the inner .xml file directly if you have already extracted it.
Understanding the Results
- DMARC Pass — the message passed SPF or DKIM alignment with your domain policy.
- DMARC Fail — neither SPF nor DKIM was aligned; the disposition field shows what the receiving server did (none / quarantine / reject).
- Source IP — the IP address that delivered the message. Unknown IPs sending on your behalf may indicate spoofing or a misconfigured sending service.
- Disposition — the action taken by the receiver:
none(delivered),quarantine(spam), orreject(blocked).
