MIME messages can have so-called preambles and epilogues (see RFC 2046), which are ‘discardable’ text parts outside of the MIME harness (boundaries). One application is to signal that the message is a multi-part MIME message to non-MIME capable clients.
IMAP servers allow partial fetches of all kinds of parts and subparts of a (MIME) message, but I did not find a way to get just the preamble and epilogue. (Of course it is possible to fetch the whole message and do client-side MIME parsing, but I would like to use the server.)
Is it possible to fetch just the preamble and epilogue, or not? If yes, how?
(This is just out of curiosity, without a specific application in mind.)
