The IESG has approved the following document: - 'Email Greylisting: An Applicability Statement for SMTP' (draft-ietf-appsawg-greylisting-09.txt) as Proposed Standard This document is the product of the Applications Area Working Group. The IESG contact persons are Barry Leiba and Pete Resnick. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-appsawg-greylisting/ Technical Summary Preferred techniques for handling email abuse explicitly identify good actors and bad actors, giving each significantly differential service. In some cases an actor does not have a known reputation; this can justify providing degraded service, until there is a basis for provider better service. This latter approach is known as "greylisting". Broadly, the term refers to any degradation of service for an unknown or suspect source, over a period of time. Working Group Summary There was nothing of note. Because this is documenting existing practice, there was broad agreement no real debate about the technical details. Document development was mostly a matter of wordsmithing and clarifying, to make sure the text was accurate and complete. Document Quality This technique is quite widely implemented, and has been discussed in the community for some time. This is documenting that implementation, demonstrating how to apply SMTP to this use case. Personnel Document shepherd: Alexey Melnikov Responsible AD: Barry Leiba
