Use this information to configure your network, users, servers (including Web servers), directory services, security, messaging, widgets and live text, and server clusters.
Configuring users and servers
Topics in this section describe how to set up users and servers.
Configuring messaging
This section provides an overview of messaging and describes how to set up mail routing, how to set up and customize mail servers, and how to track mail.
The POP3 service
POP3 (Post Office Protocol Version 3) is an Internet mail protocol that allows a user running a POP3 client -- for example, the Notes® POP3 client, Eudora Pro, or Microsoft™ Outlook Express® -- to retrieve mail from a server that runs the POP3 service. You can set up a Domino® server to run the POP3 service. The Domino server receives and stores mail for POP3 users, who can then connect to the server to retrieve their mail.
Setting up the POP3 service
The Domino® POP3 service can run on any Domino server on which a TCP/IP port is configured. The POP3 protocol provides a mechanism for retrieving mail only; POP3 clients send mail using the SMTP protocol.
Starting and stopping the POP3 service
You can load the POP3 service manually or start it automatically when you start the Domino® server.

- Configuring a network
  This section presents the planning concepts and setup procedures necessary for a successful HCL Domino® deployment over a network. It provides information on network protocols from a Domino perspective but does not attempt to provide general network information.
- Configuring users and servers
  Topics in this section describe how to set up users and servers.
  - Understanding the Server document
    The Server document is set up when you register a server. It contains many of the settings that define how your server operates.
  - Policies
    Use Domino® policy settings to control how users work with Notes®. A policy is a document that identifies a collection of individual policy settings. Policy settings documents define a set of defaults that apply to the users and groups to which the policy is assigned. You can change policy settings and they will be automatically applied to the assigned users and groups.
  - Defining default settings for Notes® user registration
    Before you register new Notes® users, you can specify default settings that apply to all users. Default settings simplify user registration and ensure user settings consistency. You can define many default settings, such as what mail server users have or what certifier ID to use for user registration. You can also specify a default workstation execution control list (ECL) to protect data from unauthorized workstation access.
  - Using groups
    Groups are lists of users, groups, and servers that have common traits. They are useful for mailing lists and access control lists. Using groups can simplify administration tasks.
  - Replicas
    You can make a database available to users in different locations, on different networks, or in different time zones, by creating replicas of the database.
  - Calendars and scheduling
    The calendar and scheduling features allow users to check the free time of other users, schedule meetings with them, and reserve resources, such as conference rooms and equipment.
  - Editing the notes.ini file
    The Domino and Notes notes.ini files contain the settings required for the server and client to operate correctly. If you modify or add settings in a notes.ini file, do so cautiously and never edit the file directly with a text editor.
  - Configuring directory services
    This section describes how to plan, set up, and use HCL Domino® directory services.
  - Configuring messaging
    This section provides an overview of messaging and describes how to set up mail routing, how to set up and customize mail servers, and how to track mail.
    - The Domino® mail router
      The Domino® mail router (the Router) is a special server task responsible for the delivery and transfer of the messages in MAIL.BOX. Delivery refers to moving messages from MAIL.BOX into a local mail file or database; while transfer refers to sending messages from MAIL.BOX across the network to another server.
    - The POP3 service
      POP3 (Post Office Protocol Version 3) is an Internet mail protocol that allows a user running a POP3 client -- for example, the Notes® POP3 client, Eudora Pro, or Microsoft™ Outlook Express® -- to retrieve mail from a server that runs the POP3 service. You can set up a Domino® server to run the POP3 service. The Domino server receives and stores mail for POP3 users, who can then connect to the server to retrieve their mail.
      - Setting up the POP3 service
        The Domino® POP3 service can run on any Domino server on which a TCP/IP port is configured. The POP3 protocol provides a mechanism for retrieving mail only; POP3 clients send mail using the SMTP protocol.
        Starting and stopping the POP3 service
        You can load the POP3 service manually or start it automatically when you start the Domino® server.
        Enabling and configuring the POP3 service port
        For POP3 clients to access mail files on the server, you must enable a POP3 port on the server. You can enable the TCP/IP port, the TLS port, or both. By default, the Domino® POP3 service uses TCP/IP port 110. This topic explains how to enable and disable the POP3 port, how to set the POP3 service to use a nonstandard port, and how to change security options for the port.
      - Setting up POP3 users
        Perform these tasks to set up POP3 users.
    - The IMAP service
      The Domino® server supports the Internet Mail Access Protocol (IMAP4rev1), defined in RFC 2060, for reading mail. The Domino IMAP service lets users with IMAP mail clients access mail files on a Domino server. The IMAP service differs from the POP3 service in that users are not required to download messages to a local computer to read and manipulate them. Users can work with messages over the network, while the messages remain on the server.
    - Customizing mail
      After you set up basic mail routing, you can customize the HCL Domino® messaging system to improve performance and meet the specific needs of your organization.
  - Configuring iNotes®
    HCL iNotes® provides HCL Notes® users with browser-based access to Notes mail and to Notes calendar and scheduling features. Administrators specify mail policy and security policy settings as well as notes.ini file settings to complete the full implementation of HCL iNotes.
  - Configuring Web servers
    This section describes how to set up the HCL Domino® Web server, and the Domino Web Navigator.
  - Setting up a cluster
    Setting up a cluster includes the tasks of creating and verifying that it is working correctly, and then setting up user access, mail, replications, size quotas, directory assistance, roaming, web navigation, and use of a private LAN in the cluster.
  - Configuring Widgets and Live Text
    Widgets and Live Text enables end users to see and act on Live Text in supported documents, including HCL Notes® mail, using XML extensions (widgets) created specifically for their use.
  - Domain Search
    Notes® client and Web users can use Domain Search to search an entire Domino® domain for database documents, files, and attachments that match a search query.

Starting and stopping the POP3 service

You can load the POP3 service manually or start it automatically when you start the Domino® server.

About this task

Table 1. Ways to start or stop the POP3 service
To do this	Perform this task
Start the POP3 service manually	Enter the following command at the console: `load POP3`
Start the POP3 service automatically when you start the Domino® server	Edit the `ServerTasks` setting in the NOTES.INI file to include the command POP3. Domino® adds the POP3 task by default to the NOTES.INI file if you select the POP3 service during installation.
Stop the POP3 service	Enter the following command at the console: `tell POP3 quit`
