Post Office Protocol Version 3

The Post Office Protocol has been in use since 1984 and is one of the most commonly used email protocols alongside IMAP and Exchange; the current revision is version 3. POP3 is a simple protocol that functions in a download-and-delete manner (commonly referred to as "maildrop"). This means that it downlods the email to the users computer then deletes the email from the mail server.
