Approach T Create Top-Level, RFC 822 Message Attribute, Message-Context T Use of Attribute is Local to UA or MTA S Presentation / Icons S Viewer to Use S Reply Composition Tool S etc. T Only a Hint: OK if Wrong S Otherwise Allows Mail Bomb Attack By Sending Messages With Wrong Message Context December 2000 draft-ietf-vpim-hint-01.txt 3
