I like the idea of using Notification Center to give me a small alert when I get an email but am using another app. But I am getting alerts (appear as a momentary bar at the top of the screen) for new emails even when email isn't running. This confuses me as I wouldn't think the email client is checking for mail or knowing any exists on the server unless it is running. Can I turn this off or otherwise configure it differently? PS YES, email is not running. I know how to close apps and am sure it is not running.
