While trying to setup the Mail application on my new iMac with Snow Leopard, I ran into difficulty. I use Yahoo Mail. The Mail application on the iMac tells me that I have to upgrade to Yahoo Mail Plus, which of course costs $19.00 per year. Why won't it setup Mail using the standard Yahoo Mail? Does that make sense? I found a temporary fix by going with GMail, which setup fine in the Mail application. But would like to continue with Yahoo Mail if possible.
