OLEXP: Setting Up Internet Mail for Different SMTP and POP3 Servers

This article describes how to use different servers for sending and receiving Internet mail.

When you use the Internet Mail Service with Microsoft Exchange Server clients or with Outlook Express, Post Office Protocol version 3 (POP3) is used solely for receiving mail. Simple Mail Transfer Protocol (SMTP) is used solely for sending mail on the Internet. Although most Internet service providers (ISPs) have both POP3 and SMTP set up on the same server, you may encounter service providers that have different servers for these tasks. If you encounter such a provider, you can configure the Internet Mail Service to use different servers for sending and receiving mail. To configure the Internet Mail Service to do so, use one of the following methods, as appropriate.

Exchange Server Clients

Use the following steps for Outlook 97, Outlook 98 installed with the Corporate or Workgroup option (CW), Outlook 2000 (CW), and Exchange Client.

NOTE: To determine your Outlook installation type, click About Microsoft Outlook on the Help menu. In About Microsoft Outlook, you should see "Corporate or Workgroup" if you have the Corporate or Workgroup installation.

1. Quit the Exchange Server client.
2. Click Start, point to Settings, click Control Panel, and then double-click Mail And Fax.
3. Click Internet Mail Service, and then click Properties.
4. In the Internet Mail Server box, type the name of the POP3 server (the server from which you receive mail).
   
   NOTE: The name of the POP3 server is provided by your ISP. If you do not know the name of the POP3 server, contact your ISP.
5. Click Advanced Options.
6. Type the name of the SMTP server (the server that sends your mail) in the text box.
   
   NOTE: The name of the SMTP server is provided by your ISP. If you do not know the name of the SMTP server, contact your ISP.
7. Click OK or Close until you return to Control Panel.

When you next use the Exchange Server client, outbound mail is sent to the SMTP server that you specified.

Outlook Express, Outlook 98 (IMO), and Outlook 2000 (IMO)

Use the following steps for Outlook Express, Outlook 98 installed with the Internet Mail Only option (IMO), and Outlook 2000 (IMO).

NOTE: To determine your Outlook installation type, click About Microsoft Outlook on the Help menu. In About Microsoft Outlook, you should see "Internet Mail Only" if you have the Internet Mail Only installation.

1. In Outlook Express, Outlook 98 (IMO), or Outlook 2000 (IMO) (as applicable), click Accounts on the Tools menu.
2. Click the Mail tab, click Properties, and then click the Servers tab.
3. In the Outgoing Mail (SMTP) box, type the name of the SMTP server (the server that sends your mail).
   
   NOTE: The name of the SMTP server is provided by your ISP. If you do not know the name of the SMTP server, contact your ISP.
4. In the Incoming Mail (POP3) box, type the name of the POP3 server (the server from which you receive mail).
   
   NOTE: The name of the POP3 server is provided by your ISP. If you do not know the name of the POP3 server, contact your ISP.
5. Click OK, and then click Close.
