are mac.com addresses valid
I have always used the mac.com address for my email, although me.com is also usable. Yesterday people who write to my mac.com email reported that the mail derlivery system reported that no such address existed. Is this a temporary problem? I have lots of bill pay and other accounts where I list my mac.com address.
