A new Request for Comments is now available in online RFC libraries. RFC 7293 Title: The Require-Recipient-Valid-Since Header Field and SMTP Service Extension Author: W. Mills, M. Kucherawy Status: Standards Track Stream: IETF Date: July 2014 Mailbox: wmills_92105@yahoo.com, msk@fb.com Pages: 24 Characters: 54440 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-appsawg-rrvs-header-field-11.txt URL: http://www.rfc-editor.org/rfc/rfc7293.txt This document defines an extension for the Simple Mail Transfer Protocol (SMTP) called "RRVS" to provide a method for senders to indicate to receivers a point in time when 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. This document is a product of the Applications Area Working Group Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements. Please refer to the current edition of the Internet Official Protocol Standards (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
