The POP3 server name is the computer name of the Microsoft Exchange Server computer that has the POP3 mailbox account that the POP3 client accesses.
Note Some POP3 clients, such as Eudora Light, do not allow you to specify the name of the POP3 server. If this option isn't available, you can often specify the name of the POP3 server in the POP3 account field. To do so, add an at sign (@) and the server name to the end of the POP3 account. For example, if your POP3 account is SuzanF, and the server your account is located on is called Exchange1, specify your POP3 account as SuzanF@Exchange1.
