E-mail
Delivering e-mail can be thought of as a three-stage process, very much like sending a
letter through the local post office.
- You take your letter to the post office and mail it.
- The postal service delivers your letter to the post office at the far end.
- The recipient goes to the post office and picks up the letter.
E-mail addressing
When you address an e- mail message, you use the format
username@domainname.
Both username and domainname are unique to help ensure that e-mail messages are delivered
to the intended recipient.
In order to send e-mail successfully you must have the right
address of the person you are
e-mailing.
