First mail sent

The first email was sent in 1971 by Ray Tomlinson, a computer programmer and engineer. At the time, Tomlinson was working on a project for the United States Department of Defense's Advanced Research Projects Agency (ARPA), which was developing a network of computers called ARPANET.

Tomlinson was tasked with finding a way to send messages between different computer systems, and he came up with the idea of using the @ symbol to separate the user's name from the hostname of the computer. He also developed the first email client, called SNDMSG, which allowed users to compose and send emails.

The first email was sent over ARPANET on October 29, 1971, from one computer to another at the University of California, Los Angeles (UCLA). The message was sent by Tomlinson himself, and it read "QWERTYUIOP" - a test message to see if the system was working properly.

The first email was sent using the following format:

From: [email address] To: [email address] Subject: [subject line] Message: [message body]

The email was sent using the SNDMSG program, which was run on a computer at the University of California, Los Angeles (UCLA). The recipient of the email was another computer at the Stanford Research Institute (SRI), which was located in Menlo Park, California.

Tomlinson's invention of email revolutionized the way people communicate, and it has since become an essential part of modern life. Today, email is used by billions of people around the world to send and receive messages, and it has become an integral part of business, education, and personal communication.
