XML / local processing

Report summary

Load XML to review senders and authentication results.

How to read DMARC results

DMARC passes when aligned DKIM or SPF passes. Failure does not prove malicious mail; forwarding or sender setup can cause it. Investigate before changing enforcement.

DMARC specification ↗

How to use

Upload an uncompressed aggregate XML report, review authentication results by source IP and export the table.

What to check

No DNS checks, IP enrichment or monitoring. Reported SPF/DKIM alignment results do not independently establish whether mail is legitimate.
