What does POP mean?

POP stands for post office protocol. It is most commonly used as a protocol to retrieve e-mail from a mail server. Most of the e-mail application is used as a POP protocol, although some can use the newer IMAP access protocol. 

There are two versions of POP called as a POP2 and POP3. The first called POP2 became a standard in the mid-'80s and it requires SMTP to send a message. The second one and newer version POP3 can be used with or without SMTP.
