Hi, I have just noticed something a bit weird on both my iPhone and iPad in iOS 8.3. Under Mail, Contacts, Calendars > (Advanced) Mail > Allow Sending From I have a strange email address listed as well as my correct iCloud address. The correct iCloud address is greyed out and I cannot alter the switched on behaviour of that button. The strange email address radio button can be switched on and off but how do I actually delete it? Thanks.
