Or as soon as the remote side acknowledges receipt?

And "acknowledgement" can happen at different levels. For example, a mail server might indicate that TCP packets containing an email have been received, but you shouldn't consider that email "sent" until the receiving side sends a "250 OK" message (which might be after SpamAssassin has run, so potentially many milliseconds later).
