If you are a Mac user and for some reason have a Hotmail account  (There is not a lot after all)  and want to use this account with Apple's superiour Mail application here is the solution:

1: Download this plugin. Choose the version matching your Mac Os X - Panther, Tiger or Leopard.

2: Read the instruction and install it.

3: Send and receive mail from your Hotmail account from your Mail application on your mac.

I am using it for my Hotmail, though I have a new email which I prefer: This e-mail address is being protected from spambots. You need JavaScript enabled to view it
