POP (Post Office Protocol) - The protocol that an e-mail server and client usewhen the client requests the downloading of e-mailmessages.
A typo of "IMAP 4", which is the "Internet Message Access Protocol" for accessing email messages.
Most email programs that use individual clients use POP (Post office protocol). Web based programs like Yahoo and Gmail use http protocol.
The POP protocol, by default, downloads messages to your computer and then deletes them from the mail server. If you leave all of your email on a primary computer (for example, your office computer) but want to have access to recently received email on a secondary computer (a home computer), you should leave your messages on the server for a limited period of time.
IMAP means Internet Message Access Protocol. In relation to email, IMAP enables one to access their email messages no matter where in the world they are.
Most email clients use one of three protocols to receive an email message. They are SMTP (Simple Mail Transfer Protocol), POP (Post Office Protocol), or IMAP (Internet Message Access Protocol).
Simple Mail Transfer Protocol, is the technology used to send out email messages. It goes hand in hand with POP (Post Office Protocol) that is, typically, employed for receiving emails from a web server to an email program or an email client.
