I realize (having read the RFC), that IMAP does not deal with the envelope "From " at all. I also realize that IMAP calls something else the "envelope", so I'll refer to it as the Unix (mbox) "From " line.
Often called the "From_" line as well
However, the mbox format does store those lines, and they even still have some meaning.
Why not let your MDA or local delivery agent add a proper Return-Path: header. It contains the same information as the From_ line, but it works with all mailbox types, it's easier to parse and you can get at it using IMAP.
That is a good positive suggestion about how to maintain "envelope from." I don't think it counters the desire *not* to muck with the existing "From_" line though. I would not want that disturbed without some very good reason (and I can't really think of one).
