Yesterday I started to receive this strange email error for every message that I send from one of my iCloud accounts (all others seem to be functioning fine). Does anyone have any idea what might be happening? I have done a search and nothing really comes up. I think the system is suggesting that the @me.com account is not valid, but it clearly is.
