Several MacMinute readers reported earlier today that emails sent to .Mac users were being returned with a message stating that the account was over its storage limit. Apple has now addressed the issue, saying the problem has been fixed. “A small number of customers were having difficulties receiving mail due to database issues,” the company said in a note on its .Mac support site. “The sender of the email will receive a bounce-back claiming that the destination account is over quota. The issue is now resolved and mail should be delivered as expected.”
