Question: no sender emails from 1969-12-31
My inbox filled yesterday with over 1700 (yes) emails from 'No Sender' with No Subject and the date code above from 1969. I see this has happened to others a few years ago - and the fix was to 'restart' the device. (in my case an iPhone 7) Are any additional 'security measures' needed?
iPhone 7, iOS 11.1.2
