What is a 'RUF' in the context of DMARC reporting, and why is it important?

RUF stands for 'Report URI Forwarding'. It's a mechanism where a DMARC reporting endpoint (the address where DMARC reports are sent) forwards those reports to a third-party service, like Cloudflare. This allows organizations to centralize DMARC report analysis even if their email sending infrastructure is distributed across multiple providers.
