[Asrg] 6. Proposals - Trust of Addressing Information SMTP Extension

[Yakov Shafranovich <research@solidmatrix.com>]

Abstract of the Internet Draft 
(http://www.ietf.org/internet-drafts/draft-pelletier-smtp-trust-00.txt):

Abstract
   This document defines an SMTP service extension [ESMTP] whereby an
   SMTP client may establish a trust relationship with the server
   attesting its confidence in the validity of the originator of a
   message.  This confidence, or its absence, can then be used to
   mitigate the cost of undesirable messages (primarily spam) without
   disrupting operations between, or with, SMTP implementations not
   supporting the extension.
