Abstract

� � This document describes the use of a mechanism for identifying body

� � parts that a sender deems critical in a multi-part Internet mail

� � message.� The mechanism described is a parameter to Content-

� � Disposition, as described by RFC 3204.

� � By knowing what parts of a message the sender deems critical, a

� � content gateway can intelligently handle multi-part messages when

� � providing gateway services to systems of lesser capability.� Critical

� � content can help a content gateway to decide what parts to forward.

� � It can indicate how hard a gateway should try to deliver a body part.

� � It can help the gateway to pick body parts that are safe to silently

� � delete when a system of lesser capability receives a message.� In

� � addition, critical content can help the gateway chose the

� � notification strategy for the receiving system.� Likewise, if the

� � sender expects the destination to do some processing on a body part,

� � critical content allows the sender to mark body parts that the

� � receiver must process.
