Chapter 15
Understanding Messaging Server Pre-Installation Considerations and Procedures

This chapter describes considerations you need to think about, and procedures you need to perform, before installing Messaging Server. See the Sun Java Enterprise System 2005Q1 Installation Guide for instructions on running the Java Enterprise System installer:

This chapter contains the following sections:

Messaging Server Installation Considerations

This section describes installation considerations that help you prepare to install Messaging Server.

Messaging Server Installation Worksheets

When installing Messaging Server, use the following installation worksheets to record and assist you with the installation process. You can reuse these installation worksheets for multiple installations of Messaging Server, uninstallation, or for Messaging Server upgrades.


Record all the port numbers you specify during the installation, along with the specific component using that port number.

The following worksheets are included:

Directory Server Installation Worksheet

You either installed Directory Server through the Java Enterprise System installer, or have a previous Directory Server installation. Record your Directory Server installation and configuration parameters in the following table. You will need these parameters when you install and configure Administration Server and Messaging Server, as well as your initial Messaging Server runtime configuration. For additional help, see the Sun Java System Messaging Server Administration Guide:

Administration Server Initial Runtime Configuration Worksheet

When you run the Administration Server initial runtime configuration program through the Java Enterprise System installer, record your installation parameters in the following table. You will need some of these parameters for the Messaging Server initial runtime configuration. You might also refer to your Directory Server Installation Worksheet to answer certain questions.

Table 15-3  Administration Server Initial Runtime Configuration Program Parameters 




Your Answer

Fully Qualified Domain Name

Fully qualified domain name for the host machine.


Server Root Definition

Installation Root of the Administration Server dedicated to holding the server program, configuration, maintenance, and information files.



UNIX System User

Certain privileges designated to system users to ensure they have appropriate permissions for the processes they are running. Always use root.



UNIX System Group

The group to which certain UNIX System users belong. Always use other.



Configuration Directory Server

Host and Port specified on Directory Server Installation Worksheet.


Port 390


Configuration Directory Server Administrator and Password

Administrator ID specified on Directory Server Installation Worksheet.

Password of Administrator ID.




Administration Domain

A region of administrative control.

If you have installed Messaging Server and Directory Server on the same machine, then you should choose the same Administration Domain on Directory Server Installation Worksheet.

System Lab2


Administrative Server Port

A unique port number dedicated to the Administration Server.



Choosing Which Messaging Server Components to Configure

When you install Messaging Server software, the Java Enterprise System installer installs all the Messaging Server packages. You then configure the appropriate Messaging Server component (MTA, Message Store, Messenger Express, MMP) on a Messaging host through the Messaging Server configuration program.

The following table shows which components you need to configure for each type of Messaging host.

Table 15-4  Which Messaging Server Components to Configure?  

Type of Messaging Host Being Configured

Needs These Components Selected in the Configurator Program


Message Transfer Agent

Message Store (back end)

Message Transfer Agent, Message Store, Messenger Express

Note: You need to configure the store for an MEM proxy after configuration is done.

Messenger Express (front end only, no store or SMTP function)

Messenger Express, Messaging Multiplexor

Note: If you are only configuring Messenger Express, you must also select the Message Store and the MTA, or at least be able to point to an existing MTA.

Message Multiplexor (front end only, no store or SMTP function)

Messaging Multiplexor


Configuring the LMTP delivery mechanism requires configuration on both the MTAs and on the back-end stores. See the Sun Java System Messaging Server Administration Guide for instructions on configuring LMTP:

Disabling the sendmail Daemon

Prior to installing Messaging Server, you should disable the sendmail daemon if it is running. The Dispatcher, under which the Messaging Server SMTP server runs, needs to bind to port 25. If the sendmail daemon is running (on port 25), the Dispatcher will not be able to bind to port 25.

    To Disable the sendmail Daemon
  1. Change to the /etc/init.d directory.
  2. cd /etc/init.d

  3. Stop the sendmail daemon if it is running.
  4. ./sendmail stop

  5. Modify /etc/default/sendmail by adding MODE="".
  6. If the sendmail file does not exist, create the file and then add MODE="".

    If a user accidentally runs sendmail start, or if a patch restarts sendmail, then adding this modification prevents sendmail from starting up in daemon mode.


    In some cases (especially on Solaris 10), even after you run the /etc/init.d/sendmail stop command, sendmail is autorestarted. In this case, use the following command to stop the sendmail process:

    svcadmin disable network/smtp:sendmail
