Before there was any internet, before there was the world wide web, and even before the term "information superhighway" was coined, there was email. In fact, email was one of the first widely-used applications on the ARPANET, the precursor to today's internet.
The history of email is a long and winding one, with many different people playing a role in its development. However, there is one person who is generally credited with inventing email: Ray Tomlinson.
In the early 1970s, Tomlinson was a computer engineer working for Bolt Beranek and Newman (BBN), a company that was contracted by the U.S. Department of Defense to develop ARPANET. At the time, ARPANET was a network of computers that allowed researchers to share files and send messages to each other. However, there was no way to send a message from one computer to another on the network.

ARPANET engineer
Ray Tomlinson was an ARPANET engineer. ARPANET was a network of computers that was developed by the U.S. Department of Defense in the 1960s. It was the precursor to today's internet.
-
ARPANET connections:
ARPANET allowed researchers to share files and send messages to each other. However, there was no way to send a message from one computer to another on the network.
-
Email development:
Tomlinson saw the need for a way to send messages between computers on ARPANET. He developed a program that allowed users to send messages to each other. This program was the first email system.
-
Email standards:
Tomlinson also played a key role in the development of email standards. He helped to develop the Simple Mail Transfer Protocol (SMTP), which is the protocol used to send email messages. He also helped to develop the Post Office Protocol (POP), which is the protocol used to retrieve email messages.
-
Global impact:
Tomlinson's work on email had a profound impact on the world. Email has revolutionized the way we communicate. It is now an essential tool for business, education, and personal use.
ARPANET engineers played a vital role in the development of email. Their work made it possible for people to send messages to each other across a network. This was a major breakthrough that paved the way for the development of the internet.
1971: first email
In 1971, Ray Tomlinson sent the first email message. This was a major breakthrough in the history of communication.
-
ARPANET network:
Tomlinson sent the first email message over the ARPANET network. ARPANET was a network of computers that was developed by the U.S. Department of Defense in the 1960s. It was the precursor to today's internet.
-
Simple Mail Transfer Protocol (SMTP):
Tomlinson used a program called SNDMSG to send the first email message. SNDMSG was a simple program that allowed users to send messages to each other on ARPANET. However, SNDMSG did not have a standard way to format email messages. Tomlinson developed the Simple Mail Transfer Protocol (SMTP) to address this issue. SMTP is still used today to send email messages.
-
The message:
The first email message was a simple test message. It consisted of the word "TEST" sent from one computer to another on ARPANET. The message was successfully delivered, and Tomlinson had invented email.
-
Impact:
The first email message was a major breakthrough. It paved the way for the development of email as we know it today. Email has revolutionized the way we communicate. It is now an essential tool for business, education, and personal use.
The sending of the first email message in 1971 was a pivotal moment in the history of the internet. It marked the beginning of a new era of communication.
@ sign separator
Before Ray Tomlinson invented email, there was no standard way to format email addresses. This made it difficult to send email messages to people on different networks.
Tomlinson solved this problem by introducing the @ sign as a separator between the user name and the domain name in an email address. The @ sign is used to indicate that the email message is being sent to a specific user on a specific domain.
For example, in the email address [email protected], the @ sign separates the username (username) from the domain name (example.com). This tells the email server that the message is being sent to the user "username" on the domain "example.com".
The @ sign is a simple character, but it is essential for the functioning of email. Without the @ sign, it would be very difficult to send email messages to people on different networks.
The @ sign is now a ubiquitous symbol in the world of email. It is used in every email address, and it is recognized by email servers all over the world. Tomlinson's decision to use the @ sign as a separator in email addresses was a stroke of genius. It made email much more accessible and使いやすい.
Email standards
In the early days of email, there were many different email systems. These systems were not compatible with each other, which made it difficult for people to send email messages to people on different systems.
To address this problem, Ray Tomlinson and other email pioneers developed email standards. These standards define how email messages should be formatted, sent, and received. The most important email standards are:
- Simple Mail Transfer Protocol (SMTP): SMTP is the protocol used to send email messages. It defines how email messages should be formatted and how they should be transferred from one email server to another.
- Post Office Protocol (POP): POP is the protocol used to retrieve email messages. It defines how email clients (such as Microsoft Outlook and Apple Mail) can connect to email servers and download email messages.
- Multipurpose Internet Mail Extensions (MIME): MIME is a standard that defines how different types of data (such as text, images, and attachments) can be sent in email messages.
These standards have made it possible for email to be used by people all over the world. Without these standards, email would be a much less useful and accessible tool.
Email standards are essential for the functioning of email. They ensure that email messages can be sent and received by email clients and servers all over the world. Email standards have made email a truly global communication tool.
SMTP protocol
The Simple Mail Transfer Protocol (SMTP) is the protocol used to send email messages. It defines how email messages should be formatted and how they should be transferred from one email server to another.
-
Email message format:
SMTP defines the format of email messages. This includes the header information (such as the sender's and recipient's email addresses) and the body of the message.
-
Email message transfer:
SMTP defines how email messages are transferred from one email server to another. This process is called "email routing". SMTP uses a store-and-forward mechanism to transfer email messages. This means that email messages are temporarily stored on email servers as they are being routed to their final destination.
-
Error handling:
SMTP defines how email servers should handle errors that occur during the email transfer process. This includes errors such as incorrect email addresses and full mailboxes.
-
Security:
SMTP supports a variety of security mechanisms to protect email messages from unauthorized access and modification. These mechanisms include encryption and authentication.
SMTP is a vital protocol for the functioning of email. It ensures that email messages can be sent and received by email clients and servers all over the world. SMTP is a reliable and secure protocol that has been in use for over 40 years.
POP3 protocol
The Post Office Protocol (POP) is the protocol used to retrieve email messages from an email server. It defines how email clients (such as Microsoft Outlook and Apple Mail) can connect to email servers and download email messages.
-
Email message retrieval:
POP3 defines how email clients can retrieve email messages from an email server. This includes logging into the email server, selecting the email messages to be downloaded, and downloading the email messages to the email client.
-
Email message deletion:
POP3 defines how email clients can delete email messages from an email server. This allows email users to manage their email storage space and keep their inbox organized.
-
Multiple email accounts:
POP3 supports the use of multiple email accounts. This allows email users to access all of their email accounts from a single email client.
-
Security:
POP3 supports a variety of security mechanisms to protect email messages from unauthorized access and modification. These mechanisms include encryption and authentication.
POP3 is a simple and reliable protocol that has been used to retrieve email messages for over 30 years. It is supported by all major email clients and email servers.
