A new Request for Comments is now available in online RFC libraries. RFC 2919 Title: List-Id: A Structured Field and Namespace for the Identification of Mailing Lists Author(s): R. Chandhok, G. Wenger Status: Standards Track Date: March 2001 Mailbox: chandhok@within.com, wenger@within.com Pages: 9 Characters: 18480 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-chandhok-listid-04.txt URL: ftp://ftp.rfc-editor.org/in-notes/rfc2919.txt Software that handles electronic mailing list messages (servers and user agents) needs a way to reliably identify messages that belong to a particular mailing list. With the advent of list management headers, it has become even more important to provide a unique identifier for a mailing list regardless of the particular host that serves as the list processor at any given time. The List-Id header provides a standard location for such an identifier. In addition, a namespace for list identifiers based on fully qualified domain names is described. This namespace is intended to guarantee uniqueness for list owners who require it, while allowing for a less rigorous namespace for experimental and personal use. By including the List-Id field, list servers can make it easier for mail clients to provide automated tools for users to perform list functions. The list identifier can serve as a key to make many automated processing tasks easier, and hence more widely available. This is now a Proposed Standard Protocol. 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.
