Thanks for everyones help. I ended up figuring it out... the problem was that
the Windows Mail that came with Vista on my computer does accept http's
(which covers most e-mail services). So, I ended up installing a program
called "Windows Live Mail Beta" and it fixed everything. It even
automatically detected which server to use for each of my e-mail providers.
Now, with Yahoo you have to subscribe to their Yahoo Mail Plus (for a charge,
of course) if you want to be able to use it on the Windows Mail. Maybe all of
this may help someone else out and they won't have to go through everything
that I have. Anyways, thanks again to everyone who helped!
