　　The history of email is older than the Internet. It was not really invented but developed from simple beginnings. Email messages at first were not sent; they were left behind like leaving a note on someone’s desk. This message would be easily seen by the user when logged on.

　　The first email system of this type was called MAILBOX. It was used in 1965 at the Massachusetts Institute of Technology. SNDMSG was another early program that could send messages on the same computer. Thus before the arrival of the Internet, email messaging was only done with the same computer. When the Internet was developed, the problem at the time was sending the message to the right person. While the computers could recognize and talk to each other, identifying(证实) a particular person to receive the email message was not simple at all.
