From a brief look at a few example multipart mails in my inbox, there
isn't any kind of table of contents referring to the parts; they are
simply separated by a boundary string. So to be able to publish the
internal structure of the mail one would have to parse it completely,
which means downloading it completely.
It's done by the server, acquired via FETCH BODYSTRUCTURE. Otherwise,
client doesn't know the structure of the message and has to download
the entire message contents all at once, whether wanted or not. I think
it's a valuable feature, but maybe that's just me.
