Email Communication

Abstract

Ray Tomlinson of BBN Technologies is recognized as the inventor of modern email, and he developed an email program in the early 1970s that allowed a user to send electronic mail to another user who was connected to a different host machine on ARPANET. The users of existing email systems could only send messages to others on the same mainframe computer, and Tomlinson introduced the @ sign to specify the machine name of the user where the message should be sent to (e.g., bob@mit). The addresses were initially of the form username@hostname, but this was later revised to username@host.domain with the development of the domain name system (DNS). Email systems are based on a store-and-forward model where the email server accepts, stores, forwards, and delivers messages, and neither the users nor their computers are required to be online.
