I don't think hotmail works with the mail program. Sorry. Also, if you use hotmail and Safari, some people are having problems getting it to open on Safari. Mine works but very slowly, even on DSL. I'm going to use Chimera until Safari is improved.
I had the same problem with hotmail, however I found a way around it.
When I first log into hotmail it sends me to a page that says my browser does not support JavaScript (it is turned on). If you go just below this it has a link that says "Hotmail Sing In".
If you click this, you will be able to login and use hotmail until you Quit Safari then you have to dp the prosess over again.
It is a little slow for Hotmail but everything else seems to fly.
