POP3 is not a valid server name. Ask your email provider (who is
probably also your internet provider) for their 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 as long as they don't call for using
the HTTP protocol. The instructions should be somewhere on their
web site. Or, if you need help finding the instructions, you could ask
on this newsgroup and find more people who will recognize their
instructions if they find them:
