Internet Express for Tru64 UNIX Version 6.8 Installation Guide (14234)

2.11 Configuring the SMTP Server
If the procedure detects that mail has been configured, it proceeds with Internet server
performance tuning (Section 2.12: Tuning Internet Server Performance).
If the installation procedure detects that mail needs to be configured for the system, the procedure
displays a form prompting you for mail configuration information.
Use the Configure SMTP Server form to set up the routing and delivery of mail for your system.
You can configure your system as one of the following:
• Standalone system (Section 2.11.1: Configuring a Standalone Mail System) — Does not send
or receive mail from any other system. A standalone system can send and receive mail from
other users on the same system only.
• Client (Section 2.11.2: Configuring a Mail Client) — Depends upon a mail server for all mail
processing. A client system must be connected to the same network as its mail server.
• Server (Section 2.11.3: Configuring a Mail Server) — Central host that performs all mail
processing, such as forwarding, routing, addressing, aliasing, and mail delivery.
2.11.1 Configuring a Standalone Mail System
To configure your system as a standalone mail system, follow these steps:
1. Choose Standalone under Select Configuration Mode.
2. Click on Configure.
3. Click on Continue to proceed with the installation.
2.11.2 Configuring a Mail Client
To configure your system as a mail client, follow these steps:
1. Choose Client under Select Configuration Mode, then click on Configure.
2. Enter the fully qualified name of the mail server that will address and route mail for your
system in the Mail Server field. If a default server name is provided, add the domain name
to fully qualify the mail server name. For example, if mailhub is shown as the default, the
fully qualified name might be mailhub.domain.name.
3. Click on Configure Client.
The installation procedure checks the syntax of your entry. If the syntax is valid, the
installation procedure informs you that the mail configuration is successful, and starts the
SMTP daemon.
4. Click on Continue to proceed with the installation.
2.11.3 Configuring a Mail Server
To configure your system as a mail server for SMTP, follow these steps:
1. Choose Server under Select Configuration Mode, then click on Configure. A top domain is
needed if your organization uses any other protocols besides TCP/IP to deliver mail (for
example, DECnet or UUCP). The top domain is used to:
• Encapsulate mail addresses for non-IP protocols before sending mail out over the
Internet
• Determine whether to omit the host name when rewriting the address on the From:
line
2. Accept the default top domain or enter another domain in the Top Domain field. (The top
domain is usually your company name and Internet domain; for example, hp.com or
isc.org.) You can enter from 1 to 21 alphanumeric characters (including special characters).
The address cannot start or end with a hyphen (-).
3. Choose one of the routing options for this mail server:
