What is IMAP4?
IMAP4:
           Abbreviation for Internet Message Access Protocol, which is a standard protocol for accessing e-mail on a remote server. It allows users to check headers of the emails; create, delete and rename mailboxes; check for new messages; permanently remove messages; search for certain parts or an entire note remotely without having to download the mail on their local hard drive. IMAP requires more Internet time as it needs continual access to the server, while handling the mail. It was developed in 1986. Its latest version is IMAP4.
What is POP3?
  POP3:           
             POP3, which is an abbreviation for Post Office Protocol 3, is the third version of a widespread method of receiving email. Much like the physical version of a post office clerk, POP3 receives and holds email for an individual until they pick it up. And, much as the post office does not make copies of the mail it receives, in previous versions of POP3, when an individual downloaded email from the server into their email program, there were no more copies of the email on the server; POP automatically deleted them.
POP3 makes it easy for anyone to check their email from any computer in the world, provided they have configured their email program properly to work with the protocol.
