POP3 (Post Office Protocol version 3) is the protocol that allows retrieving emails from a mail server. Under POP3, the messages are held on the server until they are downloaded by the client. Once downloaded, they are deleted from the server, unless the client is set up to leave a copy on the server. IMAP, on the other hand, allows messages to be stored on the server and accessed from multiple devices, without deleting them unless instructed to do so. SMTP is a protocol for sending emails, and NNTP is a protocol for accessing newsgroups.
