Sun Internet Mail Server 3.5 Advanced Installation Guide: 6

Specifying Core Server Configurations

FIGURE 6-9 Core Components Configuration Page 1

11.

Enter the values in the SIMS core components configuration pages.

You may accept the default configuration values if they meet the requirements of your mail server.

Mail Server Domain Name Suffix--Enter the fully-qualified domain name of the mail server on which SIMS is being installed. For example, if this server resides in the eng domain at sun, then specify eng.sun.com in this field. This parameter has no default value; However, if installation can determine the domain name from resolv.conf, this value will be automatically supplied. This value can be the same as the Organization Top Level Domain Name field.

Note - SIMS 3.5 checks for a fully-qualified domain name and will display error messages, depending on its finding. See Chapter "Troubleshooting SIMS Server," for more information on configuring DNS setup.

Organization Top Level Domain Name Suffix--Enter the highest level domain name used within your organization. For example, the top level domain name for Sun Microsystems could be sun.com. This value can be the same as the Mail Server Domain Name.

Postmaster User ID--The Solaris user listed in this field has permission to run all SIMS commands, programs, and start or stop daemons on the mail server. By default installation assigns inetmail as the postmaster (the reserved user ID 72). Your input in this field should not exceed 64 characters. Although it is recommended that you use inetmail, you can change the default user name during the installation. You do not need to provide a password. However, the first time the postmaster logs into the mail server, the postmaster will be prompted for a new password before being able to execute any SIMS commands on the mail server.

You will need this postmaster name to administer the mail server after installing SIMS.

Administrator Name--Enter the administrator's name. The default name is admin. The administrator's name is needed to configure the mail server using the SIMS Administration Console after the installation is complete. Your input in this field should not exceed 64 characters. The name you provide in this field is logged in the directory configuration file so that the administrator always has access to the directory. This enables the administrator to solve problems associated with access control.

Administrator Password--Enter the administrator's password. The default password is secret. Once the installation is complete, the administrator's password is needed to configure the mail server using the Administration Console. The password you provide in this field is logged in the directory configuration file. By default, this password is stored encrypted.

Firewall Location--Choose the button that best indicates the location of your mail server in relationship to your company's firewall machine. The firewall controls access between the internet and your company's internal network.

No--Indicates that your mail server is on or outside the firewall, or if your company has no firewall.

Yes--Indicates that your mail server is behind a firewall. You will then be asked to specify the name of the smart host, which is the machine with more routing information and capabilities than your mail server.

Smart Host--If you chose to put your mail server behind a firewall, you need to enter the fully-qualified hostname of the machine that has the routing information about your mail server. If your mail server cannot route mail to a recipient's address, it forwards the message to its smart host.

A smart host usually knows how to route messages through your company's firewall. Without routing information, the mail server cannot forward messages outside the firewall. It may only be able to communicate with machines in its own domain, specified domains, or with its peers. In small companies, the smart host may also serve as the firewall machine, providing a communication link between the company and the outside mail community. If neither the smart host nor the firewall machine can route a recipient's address, they return the message to the sender with a non-delivery notice.

VAR MAIL Support-- Click on the button that best indicates your company's plans for this mail server. SIMS supports both /var/mail and Sun Message Store users. Sun Message Store (that runs under the user id inetmail), however, is more secure than /var/mail (that runs as root). Refer to the Sun Internet Mail Server 3.5 Administrator's Guide for migration instructions.

Country Name--Select a country name. The default value is United States of America. If you plan to implement multiple mail servers that are geographically distributed in multiple countries, then enter one country only, for example, the location of the organization's headquarters. Your input in this field should not exceed 2 characters.

Organization Name--Enter your organization's abbreviated name. For example, if your mail server domain name is eng.sun.com, your company's short name is sun. Your input in this field should not exceed 64 characters.

Organizational Unit--If your DNS contains sub-domains, enter the name of the division or department name within the specified organization. For instance, if you are referring to the eng domain, you may want to fill in eng in this field, or retain the defaults provided. Your input in this field should not exceed 64 characters. You can indicate multiple organizational units, up to a maximum of three, but all the organizational units must have a parent-child relationship within the same directory tree.

FIGURE 6-11 Hierarchy of Organizational Units

Note - After you have completed the installation of the product software, you can create peer groups at the same level as the Engineering group using the SIMS Administration Console.

The difference between the Mail Server Domain Name and your company's Organization Top Level Domain Name determines the number of organizational unit listings that are displayed. As shown in FIGURE 6-11, you would see prompts for two organizational units: Engineering and Quality Assurance. If the mail server domain name and the top level domain name are the same, the Organizational Unit field will not appear.
