It could, and Dovecot does that for several commands. But I'm a bit afraid of adding such code for APPEND, because it could easily break some clients. I know an old version of Evolution broke if it got any extra data during APPEND. > How could the client distinguish between an upload progressing, and > the connection having stalled.

If your router/whatever swallows the entire 10 MB at once and starts uploading it for the next 60 seconds, I guess there's nothing that a client can do.
