So each message (apart from the leaves) has a Content-Type of
multipart/mixed, and its content is a MimeMultipart object. The
MimeMultiparts contain MimeMessages (of MIME type message/rfc822) and
other content types (the "files"), whatever they are. The leaf messages
have some other Content-Type, maybe text/plain.

Or maybe it's more complex than that? The superordinate messages contain
text as well as other messages? If so, that text is part of its
MimeMultipart content.
