Eudora may ask for your password the first time you check mail. Afterwards, it will not ask you again. Enter your password and click OK . POP stands for Post Office Protocol, a protocol that is used by almost all email servers on the internet today for receiving and holding e-mail. When you have entered your password, Eudora then will open a connection to the POP server.
POP server is just another way of saying the mail server.
Eudora will then begin downloading mail to your machine. Once finished, it will present you with this message box. Simply click on OK to dismiss the message box. The In Box You should then see your In box. This is where all incoming mail will end up.
