1. Introduction
This document describes a mechanism to allow senders of an Internet
mail message to convey the message's contextual information. Taking
account of this information, the receiving user agent (UA) can make
decisions that improve message presentation for the user in the
context the sender and receiver expects.
In this document, the "message context" conveys information about the
way the user expects to interact with the message. For example, a
message may be e-mail, voice mail, fax mail, etc. A smart UA may
have specialized behavior based on the context of the message.
This document specifies a RFC 2822 header called "Message-Context".
