I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG.

The Abuse Reporting Format (ARF) is used to report email abuse feedback between email operators, or from email operators to end user network access operators. This document is an applicability statement for using the ARF in these two contexts.
