My mail app keeps downloading hundreds of old emails which stop for several hours, then resume. Strangely these old emails don't appear in webmail (mail2web.com) which I use in the office. Also after I move them to trash most of them don't have the unread blue blob next to them (tho' a few do). I have OS10.3.9. Any suggestions please.
