1. What is E-Mail and How Does it Work?  Electronic mail (e-mail) is the most popular use of the Internet. It is a fast and inexpensive way of sending messages and data to each other.  When you send an e-mail message it is sent to a mail server which is a system that determines from the recipients address a route to send the message

2. Protocols are rules that determine how the Internet transmits messages:  SMTP (Simple Mail Transfer Protocol) decides which paths your e-mail message takes on the Internet  POP (Post Office Protocol) takes care of incoming messages  IMAP (Internet Message Access Protocol) is for retrieving mail messages from a server  MIME specifies how to encode nontext data so it can travel over the Internet

3. Email  When you receive a message, it is held on the server until you check for new messages. The software that downloads your mail to your computer is called mail client software.

4. Anatomy of an E-mail Message  An e-mail message consists of two major parts:  The message header contains the information about the message.  The message body contains the e-mail message.  The To line designates where to type the email address of the message recipient. You must type this correctly or the message will not be delivered. You can send the same message to several email addresses by typing a comma between multiple addresses.

5. Anatomy of an E-mail Message (cont.)  The From line holds the senders email address.  The Subject line allows the reader to have a hint of the message's contents and importance.  You can use Cc (carbon copy) and Bcc (blind carbon copy) to send copies of the message to people other than the recipient.

6. An attachment  An attachment is encoded so that it can "tag along" to a message and be carried safely over the Internet. You can attach more than one file to an e-mail message. To open an attachment click on the icon representing the attached file.

7. Email Signatures  An optional signature identifies more detailed information about the sender. A signature file contains the information you usually type at the end of your e-mail messages.

9. An informal signature contains:  senders name  e-mail address  graphics  quotations  other casual information  E-Mail Addresses

10. An Internet Protocol address  An Internet Protocol address (IP address) identifies the computer at the o rganization you want to contact. The e-mail address must identify the recipient's user name followed by the "@" (at) sign followed by the host name. An example is amooneyhan@bscn.com amooneyhan@bscn.com  When mail cannot be delivered, a message to that effect will be delivered to the sender.

11. E-Mail Programs  Several programs for managing e-mail are available today.  Some programs are clients that run on your computer and receive mail from the mail server  Other programs run on a server machine you access from your personal computer  A dumb terminal is a computer that passes all your keystrokes to another computer to which you are connected.

You can choose to respond to all the original recipients or just the sender (Be careful; there may be blind carbon copy recipients who you are replying to).
