Wie kann ich meine alte E-Mail Adresse wieder Aktiviren, p.herrmann@mac.com?
mac.com
You can probably still use it as your Apple ID... but you cannot receive email at it. I am in the same boat. I have a @mac.com but through the .Mac -> MobileMe -> iCloud transition I stopped paying for it and now I can't receive email at it. Which is annoying, because Apple does send App Store invoices to it. (they just never arrive)
