Before Installing SLmail

Before you install SLmail, you should first verify that the TCP/IP service is installed, configured, started, and working correctly on your system. Please refer to the previous section on SLmail Requirements for instructions on verifying that TCP/IP is installed.

In order to successfully install SLmail, you need the following information about your TCP/IP configuration and your connection to your ISP. If you do not know the answers to these questions, you should search them out prior to beginning the installation process.

What is the IP address of the SLmail system?

You can determine this information from the Windows NT Control Panel.

• Double-click the Network icon.

• Select the Protocols tab.

• Double-click on TCP/IP Protocol .

• Select the IP Address tab.

• Verify that Specify an IP Address is selected. (You cannot run a mail server on a system that receives its IP address from DHCP.)

• The IP address is displayed in the top line of the text box.

  Alternatively, you can determine the IP address by typing ipconfig at the command prompt.
