DMARC RUA XML Parser

Make sense of DMARC reports

DMARC aggregate reports arrive as dense XML that is unreadable by eye, yet they contain vital information about who is sending mail as your domain. This parser turns DMARC RUA XML reports into readable summaries, showing the top sending IPs and their authentication pass and fail results.

Why these reports matter

DMARC tells receiving mail servers what to do with mail that fails authentication, and the aggregate reports tell you who is sending mail claiming to be from your domain, both your legitimate senders and any spoofers. Read as raw XML they are impenetrable; summarised, they reveal whether your own mail is passing authentication and whether anyone is impersonating your domain. That visibility is the whole point of DMARC reporting, and it is how you tune your setup and detect abuse. Parsing them locally keeps the reports, which name your infrastructure, private.

Reports you can actually read
