What are the requirements for RUA and RUF in DMARC policies?

DMARC policies utilize RUA and RUF tags for reporting. While neither tag is strictly required, RUA (Aggregate Reporting) is strongly recommended by experts, major email providers like Yahoo, and the email marketing community because it provides essential visibility into how emails are being handled, enabling monitoring of DMARC compliance and identifying potential issues. RUA specifies where aggregate reports about DMARC results should be sent, with the value being a mailto: URI. RUF (Forensic Reporting) is less critical due to privacy concerns, potential data leaks (containing personally identifiable information (PII) that often makes it useless after data trimming), and implementation challenges. It provides forensic data. It is less commonly used due to privacy concerns surrounding forensic data, and RUF reports are rarely sent. It specifies the URI(s) to which forensic (failure) feedback reports should be sent. For dedicated subdomains with a 'p=reject' policy, the RUA tag may not be required, but it's still beneficial for detecting misconfigurations or abuse.

DMARC policies utilize RUA and RUF tags for reporting. RUA (Aggregate) reports are widely recommended as they provide essential summaries of email traffic and authentication results, enabling monitoring of DMARC compliance and identification of potential issues. RUF (Forensic) reports, while offering detailed data on individual email failures, are less commonly used due to privacy concerns, potential data leaks, and implementation challenges. While neither tag is strictly required, especially with a 'p=reject' policy on dedicated subdomains, RUA is strongly advised for maintaining visibility and managing email authentication effectively. In summary, RUA is generally more important and universally supported, while RUF requires careful consideration due to privacy implications and limited availability.

Experts agree that RUA (Aggregate Reporting) is a critical component of DMARC implementation, providing essential visibility into how emails are being handled. While RUF (Forensic Reporting) can offer more granular insights into abuse instances, it's less critical due to privacy concerns. Major email providers like Yahoo are also strongly recommending the use of RUA.

DMARC policies utilize RUA and RUF tags for reporting purposes. The RUA tag specifies the URI (typically a mailto: URI) to which aggregate reports summarizing email traffic and DMARC results should be sent. RUF specifies where forensic or failure reports are sent. RUF is less commonly used due to privacy concerns.
