I have been having problems with getting emails from my @mac.com / @me.com accounts using non-Apple devices, namely Android phone and Blackberry Playbook. They were working before, but all of the sudden the email app can no longer update emails. For imap setting, I have tried: mail.mac.com mail.me.com imap-04.mail.mac.com (imap-04 found on my Mac email setting) imap-04.mail.me.com My iPhone, iPad, and iMac are working fine. So, it's just my non-Apple devices that are experiencing problem. Any clues?
