If you are using 'Outlook Express'; open Outlook express, click on 'Tools' (top bar), click 'Accounts', make sure your account is hilighted, click the 'Properties' button, click the 'Servers' button. You will see the 'Incoming Mail(POP3) and 'Outgoing Mail (SMTP)' options. Those are your pop settings. They should say something along the lines of "pop.mail.yourISP.net" and "smtp.mail.yourISP.net" . Obviously the 'yourISP.net' will depend on your service provider.
