How e-mail works

How e-mail works

             The way electronic mail works on the Internet is similar to the way the
postal system works. The  addressis the most important part of both
standard letters and e-mail messages. If the address is incorrect the
intended recipient will never see the message.
Issuing a  sendcommand at your computer is similar to placing your
letter in a mailbox. Once you’ve sent your message on  its way, you
cannot retract it.
The postal service collects mail and takes it to the localpost office for
processing and routing. When you send electronic mail, your local post
office reads the e-mail address and either delivers the  message to
another local mail account or sends it to the Internet.
As your letter travels from one post office to another,the postal
service routes it based on the address, so that it continues to move
closer to its destination.
