Yes, as I suspected, Evolution just grabs the whole message instead
of asking the server about the different parts. I think that means
that Thunderbird would be able to show the message without
downloading any large attachments, but Evolution will not show the
message until the whole thing is downloaded. Anyway, the Yahoo IMAP
implementation apparently doesn't like what Thunderbird is asking for
While I know that an IMAP server *can* be asked to send the message
(text portion) and separately deal with attachments (ignore or fetch),
I understood this to be a rarely implemented feature (on client or
server). And I'd be rather surprised that it would work with a large
mail with numerous sections/attachments (such as MIME digest mail).

There is no point trying to privately email me, I only get to see
the messages posted to the mailing list.
