For probably the last year I’ve been “losing” emails that come into Mail. Like most folks, I get a ton of email—problem ~100 emails each and every day. So, long ago I created a 2-layer mail folder structure under my Inbox and added a dozen or so filters to redirect some emails right into folders. Many other emails I manually Move to a folder after reading them. But for the last year many emails sent to a folder have “gone missing.” Not entirely gone—I can still see an email’s subject and date, but when I try to open it I (eventually) get the response, “This email has not been downloaded from the server.” And very often I’ve just read that email 10 minutes earlier.
Anyone have an idea what’s happening to these emails? Does Mail somehow lose the “pointer” to an email that’s been Moved out of my Inbox? Does the full text of an email get left behind on various servers, or left on the AT&T/YAHOO! server (my Internet service)?
