DMARC Failure Reports (RUF)
Per-message forensic reports for DMARC failures — distinct from the daily aggregate (rua=) feed. Useful for live debugging; rare in practice because of privacy concerns.
What it is
DMARC Failure (forensic) Reporting — RFC 7489 §7.3. The `ruf=` tag on a DMARC record requests redacted copies of individual messages that fail authentication, formatted per the Authentication Failure Reporting Format (AFRF, RFC 6591).
Why it matters
RUF gives per-message visibility — what header the spoofer used, what selector failed — that aggregate reports flatten away. Most major receivers (Gmail, Microsoft) have stopped sending RUF for privacy reasons, so coverage is thin; useful when investigating a specific incident, less so as ongoing telemetry.
Who it applies to
Senders investigating active spoofing campaigns or running mature email-security operations.
