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. On Tue, Oct 31, 2017 at 1:52 PM, Aki Tuomi wrote: >>> What's in your mind

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. The stress on the server is unbearable. We cannot ask users to be considerate:
