"pop" is not a valid mail server name. You get the correct mail
server names from your mail provider. Who provides your email service?
Or to ask that question another way, what is the part of your email
address after the @ symbol?
Your mail provider will typically have a web page that shows how to
set up an email program. If you need more help, tell us the name of
your email service provider. If you currently don't have an email
address, we can help with that also.
