What does the DMARC rua= tag do?

DMARC `rua=` Tag: Aggregate Report URI (rua)

The DMARC rua tag sets where ISPs deliver daily aggregate RUA reports, the XML files showing every sender, IP address, and SPF/DKIM result for your domain. Without it you get no reports.

💬 What This Tag Does

The "rua" tag tells receiving ISPs where to send daily aggregate reports in XML format. These reports show every IP that sent mail claiming to be from your domain, along with SPF and DKIM pass/fail counts. Without rua, you're flying blind. You'll have no visibility into who is sending as your domain or where your configuration is failing.
