For two days I have been unable to access Mail email but get message to try again in an hour. I think AT&T is deleting old old email data but that has nothing to do with more recent and current email; moreover I use the Apple Mail app abd internet access via Yahoo. What's going on? I need to get this work SENT - already lost a day!
