Even if your Mac is no longer supported or on Apple care you can always book an appointment with the genius bar to get questions answered regarding setting up email accounts or if something is malfunctioning.
Apple also sells one-on-one sessions if you are so inclined or need longer sessions than what the genius bar can help you with.
I wonder how "out of date" your Apple product can be and they will still help you with it? I think a trip to my local Apple Store with my trusty Apple ][+ is in order.
