Email application programs

The simple mail transport protocol (SMTP) is used to send email, and the post office protocol (POP) is used to read email.

Windows comes with an email client called Outlook Express which combines both SMTP and POP clients.

A message is composed and sent using and SMTP client. The SMTP server forwards the message to a server used by the message recipient. It is stored there until the recipient reads his or her email using a POP client. The POP client retrieves and displays the message.

Windows comes with an email client called Outlook Express (OE) which can send and receive messages. Since it is both an SMTP client and a POP client, the user must specify several parameters before using OE:

Your name
Your email address
The IP address or domain name of your SMTP server
The IP address or domain name of your POP server
Your account login name and password for POP and SMTP (alternatively, you can enter the passwords every time you run OE)

You can do that using the Windows account configuration wizard using the Tools > Accounts > New command in OE or you can directly complete and edit the account property sheet:

Another handy option is whether or not to leave messages on your POP server after you have read them. That is done on the Advanced tab of the property sheet.
