Welcome to the HCL Domino 11.0.1 documentation
Welcome to the HCL Domino® 11.0.1 documentation. Here administrators can find information about planning, installing, configuring, and administering Domino 11.0.1.
Configuring
Use this information to configure your network, users, servers (including Web servers), directory services, security, messaging, widgets and live text, and server clusters.
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.

- Translated documentation
  The HCL Domino 11.0.1 documentation is currently available in the following languages.
- What's new in Domino® 11?
  Learn about all of the new features for administrators in HCL Domino® 11.
- Overview
  Welcome to HCL Domino® Administrator Help.
- Domino trial
  A trial version of HCL Domino® 11.0.1 is available free of charge.
- Installing
  Use this documentation to install the HCL Domino® server and subsequently deploy the HCL Notes®client.
- Planning
  Use this topic as an overview of planning task.
- Configuring
  Use this information to configure your network, users, servers (including Web servers), directory services, security, messaging, widgets and live text, and server clusters.
  - 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.
  - Editing the NOTES.INI file
    You should rarely, if ever, need to modify a server's or client's NOTES.INI file. The NOTES.INI file contains many settings that Domino® and Notes® rely on to work properly. An accidental or incorrect change may cause Domino or Notes to run unpredictably. Therefore, you should edit the NOTES.INI file only if special circumstances occur or if Support recommends that you do so.
  - 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 SSL 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.
- Securing
  This section describes security features, including execution control lists, IDs, and SSL.
- Administering
  This documentation provides information about the administration tools for managing and monitoring servers and databases.
- Tuning
  Use this information to improve HCL Domino® server, Domino Web server, and messaging performance through the use of resource balancing and activity trends, Server.Load commands, advanced database properties, cluster statistics, and the Server Health Monitor.
- Troubleshooting
  This section describes how to find and solve problems with HCL Domino® server and Administrator client.
