POP is a protocol used to retrieve email messages from an Internet email server.  Generally, when you use POP it is best to use it from one particular computer.  When you download your messages, the POP email server will automatically delete them from the server when the trasfer is sucessfully completed.  If you go to another computer to connect and retrieve that same message, it will no longer be on the POP server.

You can also download a copy of new e-mail messages and not delete items from the POP3 e-mail server.  This is useful if you check your POP3 e-mail account from a number of computers or profiles.  For example, you can download a copy of the messages on your work computer, and then on your home computer, you could download the e-mail messages and delete them from the POP3 server.
