When a user types an e-mail message on a laptop or desktop machine, the e-mail client uses SMTP to submit the e-mail to a real server that can send it along to its destination.
E-mail servers themselves use SMTP to deliver messages, sending them across the Internet to the server in charge of the recipient e-mail address’s domain (the part of the e-mail address after the @ sign).
