Yahoo, unless you have the premium package, does not allow POP access. Hotmail and Gmail allow it for free. In Gmail, log-in, go to Settings, Click on Forwarding and POP, and choose your configuration options there. NExt, we will pull server information. On the same page as you are on now, click on Configuration Instructions, select your mail client, and follow the instructions provided. I'm not exactly sure about using Hotmail with POP access... I will research this for you and return soon.
