Dear LSTOWN-L Folks, With the help of <[log in to unmask]>, I found that this is simply NOT a MS Exchange issue - it's based on RFC 2298. [I guess some people might want Microsoft to be non-compliant with the standards - but that's another discussion.] Request for Comments: 2298 (March 1998) "An Extensible Message Format for Message Disposition Notifications" Oh, and thanks to <[log in to unmask]> for all that coding and effort. Wow.
