A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Applications Area Working Group Working Group of the IETF. Title : The Require-Recipient-Valid-Since Header Field and SMTP Service Extension Authors : William J. Mills Murray S. Kucherawy Filename : draft-ietf-appsawg-rrvs-header-field-11.txt Pages : 25 Date : 2014-04-19 Abstract: This document defines an extension for the Simple Mail Transfer Protocol called RRVS, to provide a method for senders to indicate to receivers a point in time when the the ownership of the target mailbox was known to the sender. This can be used to detect changes of mailbox ownership, and thus prevent mail from being delivered to the wrong party. This document also defines a header field called Require-Recipient-Valid-Since that can be used to tunnel the request through servers that do not support the extension. The intended use of these facilities is on automatically generated messages, such as account statements or password change instructions, that might contain sensitive information, though it may also be useful in other applications.
