Before you can check your e-mail, you must be connected to the Internet. This is the most common mail protocol. Using POP, mail that is sent to your e-mail address is stored on a server until you check your mail. Your messages will only be left on the server if you specify your mail program to leave messages on server. This however can sometimes cause you to receive duplicate messages when you check your mail.
POP is beneficial in that it is the quickest and easiest protocol for checking mail.
