•Enter the name of the relay system in the Relay Hostname field. You can enter from 1 to 21 alphanumeric characters (including special characters). The name cannot start or end with a hyphen (-).

•Select the relay protocol (the protocol that will be used to forward mail to the relay) from the Relay Protocol pull-down menu. SMTP is the default.

5.Enter the DECnet node address for this server (area.node) for this server in the Node Address field; for example, 32.958.

6.A pseudo domain is used by Sendmail to determine the protocol that a mail message requires. The message is properly encapsulated by Sendmail before being sent out over the Internet. Accept the default pseudo domain (ENET) or enter another pseudo domain in the Pseudo Domain field.

7.Click on Submit. A message is displayed indicating that the changes have been accepted. Click on Continue to return to the Configure Sendmail Server form.

If an error occurs, use the navigation bar to return to the Configure DNET4 Protocol form.

8.On the Configure Server form, you can select another protocol to configure.

If you are finished configuring protocols, click on Submit. A message is displayed confirming that the configuration was successful, and that the Sendmail server has been restarted. Use the navigation bar to return to the Configure Sendmail Server menu.

Configuring the DECnet/OSI Protocol

If DECnet is installed and configured on your system, you can configure the DECnet/OSI protocol.

To configure the DECet/OSI (Phase V) protocol for the Sendmail server, complete the Configure DNET Protocol form as follows:

1.Create one or more pseudo domain aliases, if needed (see Section : Creating and Deleting Pseudo Domain Aliases).

2.Create one or more host aliases, if needed (see Section : Creating and Deleting Host Aliases for a Mail Server).

3.Select one of the following routing methods:

•Internet—Forwards mail over the Internet to an unspecified gateway. The Internet depends on BIND/DNS to select an appropriate relay; therefore, you do not need to specify a relay host name for Internet routing.

•Direct—Sends mail directly to the addressee. This option is not displayed if the DECnet/OSI protocol is not installed on this server.

•Relay—Forwards mail to another system (called the relay host) for processing.

4.If you chose Relay routing:

•Enter the name of the relay system in the Relay Hostname field. You can enter from 1 to 21 alphanumeric characters (including special characters). The name cannot start or end with a hyphen (-).

•Select the relay protocol (the protocol that will be used to forward mail to the relay) from the Relay Protocol pull-down menu. SMTP is the default.

5.The default DNS Name Space is the total collection of names that one or more DECdns servers know about, look up, manage, and share. The name space for your site is the token before the colon ( : ) in your Phase V node name. For example, dec is the name space for the address dec:.foo.bar. Accept the default DNS name space or enter another name space in the DNS Name Space field.

6.A pseudo domain is used by Sendmail to determine the protocol that a mail message requires. The message is properly encapsulated by Sendmail before being sent out over the Internet.
