You need to find an email provider and set up an email account with
them. Your internet provider has probably done this for you already.
You then need to get this email provider's instructions for setting up
to use their email servers. If they haven't written instructions for
Windows Mail yet, their instructions for Outlook Express should
also work under Windows Mail if they don't call for the HTTP
protocol. The instructions should be available somewhere on their
web site. Or, you could tell us who your email provider is and see
if anyone here already knows where to find their instructions.
