Email not addressed to my .me or .icloud account is appearing in my inbox.
Why is mail that isn't addressed to my .me or .icloud account being sent to my inbox? For example, I've received mail addressed to hpyzf1qf*@gmail, ilz7xfyd4o*@icloud, and [my user name]@t-online.de. Why is this coming through? Can it be screened for and not sent through?
