1. IMAP (Internet Message Access Protocol) -is an application layer that allows an e-mail client to access e-mail on a remote mail server. It supports both on-line & off-line modes of operation. The current version, IMAP version 4 revision 1 (IMAP4rev1), is defined by RFC 3501.
2. POP (Post Office Protocol) -is an application layer Internet standard protocol used by local e-mail clients to retrieve e-mail clients to retrieve e-mail from a remote server over a TCP/IP connection. POP and IMAP are the two most prevalent Internet standard protocols for e-mail retrieval. POP has been developed through several versions, with version 3 (POP3) being the current standard. Most webmail service providers such as Gmail and Yahoo! Mail provide both an IMAP and POP3 service.
3. SMTP (Simple Mail Transfer Protocol) -is an Internet standard for electronic mail transmission across Internet Protocol networks. While electronic mail servers and other mail transfer agents use SMTP to send and receive mail messages, user-level client mail applications typically use SMTP only for sending messages, user-level client mail applications typically use SMTP only for sending messages to a mail server for relaying. For receiving messages, client applications usually use either the Post Office Protocol or the Internet Message Acess Protocol or a proprietary system
4. TelNet -is a network protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection.
5. UDP (User Datagram Protocol) -is one of the core members of the Internet protocol suite (the set of network protocols used for the Internet). With UDP, computer applications can send messages, in this case referred to as datagrams,
