The Messaging Server provides simple graphical administration using the Server Manager. This chapter describes:
Note: We strongly recommend that you implement a backup procedure for your Messaging Server immediately.
For more information, see "Chapter 2. Configuration and Administration" and "Chapter 3. Mail Administration" in the Administrator's Guide.
The Messaging Server has a single administrative account named "admin". This is the name you use to log into the Server Manager for administering your messaging server. It is a valid mail account and can receive mail.
The admin account is managed like other user accounts as described in "Managing Mail Users". You can also change the admin password by clicking on Admin Password under the System menu in the Server Manager.
Note: Before proceeding with Messaging Server configuration, we recommend that you change the initial admin password, set by default to "admin."
In addition to the admin account, the Messaging Server provides a default postmaster mail alias. Postfix (as well as most other MTAs) require that an account for "postmaster" exists so that messages to the address "postmaster@host.domain" can be delivered successfully. It also receives any error messages generated by Postfix. The postmaster mail alias is created automatically during installation with the "admin" administrator account as its sole member. This alias should not be deleted from the server.
The Server Manager is the principle Messaging Server administrative utility. It is a web-based management interface with support for all functions required to administer an office mail server, including the ability to:
Add/delete/modify virtual hosts, mail domains, mail users, and mail aliases.
Monitor mail services.
Control client user privileges (ACLs, Access Control Lists).
The Server Manager provides mail server administration screens accessible only by an administrator account with the login name "admin". By default, the Server Manager is served by the Apache webserver at:
http://hostname/msg
where hostname is the value returned by the hostname(1) on the Messaging Server system.The Server Manager screen includes menus for managing:
It also includes:
a Domain selection box.
a general HELP link that connects to the DocView online help system.
screen specific Help screens that connect to individual topics in the Administrator's Guide.
a LOGOUT button.
Note: To protect Messaging Server security, we recommend that you log out of the Server Manager, rather than simply closing the browser window, whenever you are not actively using the Server Manager.
To administer domains with the Server Manager, click on these buttons in the Domains menu:
View Domains | List the mail domains controlled by the Messaging Server. | |
Create Domain | Enter a mail domain name and description. | |
Delete Domain | Delete the domain names you select. |
The Messaging Server supports multiple mail domains, with user and alias lists displayed in per-domain views. To switch to a different domain, select it from the Domain box in the upper right of the screen.
For information about managing virtual domains (multiple mail domains presented by the same mail server), see "Managing Mail Domains" in Chapter 2 of the Administrator's Guide.
You can use the Server Manager to create and modify mail accounts for users who receive mail on the Messaging Server. In the Users menu, click on:
You can use the Server Manager to create and modify mail aliases. In the Aliases menu, click on:
Create Alias | Creates a new alias in the current domain. Required entries are marked with an asterisk (*):
If users have permission to create aliases (see "Managing System Services" below), they can also view and manage these fields. However, only the admin user can enable the following alias features (on some browsers, these options are displayed when you click on More):
When you have entered all required and optional information, click on Create to enter the new alias information. | |||||||
View Aliases | Lists all aliases in the selected mail domain, sorted by Alias. Clicking on the Alias link displays the complete alias information. From this display you can take these Alias Actions:
| |||||||
Find Alias | Searches for an alias in the selected mail domain. You can enter a full or partial word to be found in the Alias or Name fields. Click on the Alias links in the search results to display alias information and take Alias Actions. | |||||||
Delete Alias | Selects an Alias to delete. You can also delete users from the View Aliases display. |
Note: We recommend that every alias have at least two owners, and that important aliases also include the admin user as an owner or member.
Use the selections in the Server Manager System menu to control general Messaging Server system services:
