What is Email?

A short form used for Electronic Mail. One of the earliest standard Internet protocols which enables people with different computers and operating systems to communicate with each other. E-mail allows one-to-one or one-to-many mailings.

E-mail is part of the standard TCP/IP set of protocols. Sending messages is typically done by SMTP (Simple Mail Transfer Protocol) and receiving messages is handled by POP3 (Post Office Protocol 3), or IMAP (Internet Message Access Protocol). IMAP is the newer protocol, allowing you to view and sort messages on the mail server, without downloading them to your hard drive.

The Internet e-mail standards include no provision for authenticating the sender, and creates possibility of using false From addresses and routing.
