How to Configure DMARC Forensic Reports (RUF): A Technical Step-by-Step Guide for Postmaster Debugging

Short summary

DMARC Forensic Reports (RUF) provide detailed debugging information when emails fail SPF or DKIM authentication checks, helping postmasters diagnose delivery issues and detect spoofing attempts. Enable RUF by adding the ruf tag with recipient addresses and failure options to your DMARC DNS record—fo=1 triggers reports for any authentication failure. Use a dedicated secure mailbox for reports, implement strict access controls, and start with p=none policy to monitor without impacting mail delivery.
