Previous versions of this client allowed to opt-out. The latest two

I think I am not mistaken in saying that the original purpose of IMAP was to
access a remote database, vs POP's approach to download it. When the IMAP
client opens a folder, the server uploads the *index* of its content. When the
client requests a specific item, the server uploads the item

Aki, the IMAP client can receive the e-mails with an empty body without any
damage. This is how IMAP works normally. The full body is queried again by the
client when reading the e-mail for real.

That would not be nice. Breaking IMAP protocol that way. Some rate

This sounds rather dangerous. Client is expecting full body download,
not headers.

Don't tell the client about the mails -> user will miss old mails.
Stop him from fetching body with a temporary "UNAVAILABLE" failure?

By default, Apple Mail downloads all e-mails from server's account. Previous
versions of this client allowed to opt-out. The latest two versions? however,
only allow to opt-out from downloading the attachments.
