A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : The Require-Recipient-Valid-Since Header Field Author(s) : William J. Mills Murray S. Kucherawy Filename : draft-wmills-rrvs-header-field-00.txt Pages : 7 Date : 2013-07-15 Abstract: This document defines an email header field, Require-Recipient-Valid- Since, to provide a method for senders to indicate to receivers the time when the sender last confirmed the ownership of the target mailbox. This can be used to detect changes of mailbox ownership, and thus prevent mail from being delivered to the wrong party.
