My @me address has stopped sending email and receiving from several sources that it formerly trusted. It's not an account or authentication error since emails from other sources, albeit much reduced, are coming through fine. I've used the same address since I began using iOS on my iPhone 3GS. Emails from my own mother (who uses iCloud), newsletter updates from an architecture site, Amazon.com notifications, etc. It's not going in my spam/junk bin, there are no rules to be messing things up.... super frustrating because it used to be so fast and stable. Any clue as to why emails that *used to receive* are no longer receiving my mail, and vice versa? :?
