Update to Internet Message Format to Allow Group Syntax in the "From:" and "Sender:" Header Fields

Overview

RFC 6854, “Update to Internet Message Format to Allow Group Syntax in the "From:" and "Sender:" Header Fields”, is a Proposed Standard document published in March 2013 by B. Leiba. It updates RFC 5322. The canonical text is published by the RFC Editor.

Abstract

The Internet Message Format (RFC 5322) allows "group" syntax in some email header fields, such as "To:" and "CC:", but not in "From:" or "Sender:". This document updates RFC 5322 to relax that restriction, allowing group syntax in those latter fields, as well as in "Resent-From:" and "Resent-Sender:", in certain situations.

Abstract as published in the RFC, via rfc-editor.org.

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
