Configuring TCP/IP for e-mail

You need to set up TCP/IP before you can configure e-mail on your i5/OS^® operating system. If you are setting up e-mail on your system for the first time, complete the following steps. If you already have TCP/IP configured on your system, you can proceed directly to Configure Simple Mail Transfer Protocol (SMTP) and (POP) servers for e-mail.

1. In iSeries™ Navigator, expand your system > Network > TCP/IP Configuration.

2. Right-click Interfaces and select New Interface and the type of network the new interface represents. Follow the wizard's instructions to create a new TCP/IP interface. The wizard asks you to supply the following information:

   • Type of connection

   • Hardware resource

   • Line description

   • IP address

   • Host name

   • Domain name

     The host name and domain name you use for the wizard constitute your fully qualified domain name. SMTP requires a fully qualified domain name to communicate with other SMTP hosts.

     For example, if the local host name is ASHOST and the local domain name is DOMAIN.COMPANY.COM, the fully qualified domain name is ASHOST.DOMAIN.COMPANY.COM.

   • Servers to start

3. After you are finished with the wizard, right-click TCP/IP and select Properties. The TCP/IP Properties dialog appears.

4. Click the Host Table tab.

5. Click Add. The TCP/IP Host Table Entry dialog appears.

6. Enter the IP address and the host name you used in the New TCP/IP Interface wizard.

7. Click OK to close the TCP/IP Host Table Entry dialog.

8. Click OK to close the TCP/IP Properties dialog.
