Help please...I have an iMac, iPad 2 and iPhone 4S. Whenever I receive mail, I get a notification on my iPad and iPhone and receive the message. However, on the iMac, I don't always get all of the emails directed to my AT&T account and sometimes, I even fail to receive emails directed to my me.com account. I am missing emails when I don't check all devices to make sure they have received the same message. I always charge the iPad and iPhone in the evening to insure syncing occurs via Wi-Fi. Any ideas? I apologize if this question has been asked before. I tried a search and came up empty.
