DMARC ruf= Tag — Forensic Report URI (ruf)
The DMARC ruf tag specifies where to send forensic (failure) reports, which contain redacted copies of individual failing messages. Privacy concerns limit receiver support.
✅ Valid Values
mailto: URI(s), comma-separated
💬 What This Tag Does
The "ruf" tag requests forensic reports (also called failure reports) — individual per-message reports sent when a message fails DMARC. Unlike aggregate reports, these contain message details and can help diagnose specific failures. However, privacy concerns mean most major ISPs (Google, Microsoft, Yahoo) no longer send forensic reports, limiting their practical value.
