    Yes, mbox formats vary; I was describing mboxrd above, which I
believe is the current Rmail default and does not suffer from this
problem.  See bug #6574 for why mboxo, which you describe above,
corrupts messages with ">From " lines.  Either way, unescaping is
required for forwarding or resending messages (destination system may
not use mbox at all).

    Agreed.  Base64 also works.  I don't think either of the message
sending libraries in Emacs does this, however.
