Since last monday my .mac mail account keeps showing this message whenever i try to send e-mails. (see below) It has also stopped me from looking in my inbox and receiving mail. When i look in preferences it shows my mail account as offline. This has happened once before but it only lasted for a day this has now lasted just over a week has any one had this sort of problem? Advise needed please
