Welcome to the IBM® Domino 10.0.1 Administrator Help.
Configuring
Use this information to configure an IBM® Domino® network, users, servers (including Web servers), directory services, security, messaging, widgets and live text, and server clusters. Also use this information to set up IBM iNotes® on a server using Domino Off-Line Services (DOLS).
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 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 the IMAP service
You customize the IMAP service by editing the Server document and Configuration Settings document.

IBM® Domino 10.0.1 Documentation
Welcome to the IBM® Domino 10.0.1 Administrator Help.
- What's new in IBM® Domino® 10?
  Learn about all of the new features for administrators in IBM® Domino® 10.
- Overview
  Welcome to IBM® Domino® Administrator Help.
- Installing
  Use this documentation to install the IBM® Domino® server and subsequently deploy the IBM Notes® client.
- Planning
  Use this topic as an overview of planning task.
- Configuring
  Use this information to configure an IBM® Domino® network, users, servers (including Web servers), directory services, security, messaging, widgets and live text, and server clusters. Also use this information to set up IBM iNotes® on a server using Domino Off-Line Services (DOLS).
  - Configuring a network
    This section presents the planning concepts and setup procedures necessary for a successful IBM® 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 IBM® Support Services recommends that you do so.
  - Configuring directory services
    This section describes how to plan, set up, and use IBM® 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.
    - 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.
      - How Domino® modifies mail files to support IMAP
        IMAP clients use a standard Domino® mail file that must be specially enabled for IMAP. If you enable IMAP access for the mail file of a registered Notes® user, the user can access the file from either the Notes client or from an IMAP client.
      - Setting up the IMAP service
        The Domino® IMAP service can be run on any Domino server on which a TCP/IP port is configured.
      - Starting and stopping the IMAP task
        You can load the IMAP task manually or start it automatically when you start the Domino® server.
      - Customizing the IMAP service
        You customize the IMAP service by editing the Server document and Configuration Settings document.
        Enabling and configuring the IMAP service port
        In addition to enabling or disabling the IMAP TCP/IP or SSL port, you can change the port number, and enable or disable TCP/IP or SSL authentication options.
        Setting IMAP session limits
        You can set limits on IMAP sessions by setting the maximum number of IMAP sessions, or by setting a default timeout value
        Setting the IMAP service to automatically enable mail files at login
        User mail files must be specially enabled for IMAP use. After a mail file is enabled, Domino® converts information about each message in the mail file, such as its message ID and folder location, into a set of IMAP attributes. IMAP clients use these attributes to organize messages for display. An additional attribute informs the Router to add IMAP attributes to new messages delivered to the mail file.
        Enabling the IMAP service to automatically display all accessible mail folders
        The Domino® IMAP service complies with RFC 2342, which defines a method by which the IMAP service automatically presents a client with a list of all mail files to which the current user has access
        Configuring IMAP Public folders
        To provide IMAP clients with access to a public mail database you first enable a database for IMAP use, and then specify the appropriate level of access to that database for users. Finally, you designate the database as an IMAP public folder. This procedure provides steps for configuring a database as an IMAP public folder.
        Configuring Other Users IMAP folders
        If NAMESPACE support is enabled on the server, in addition to displaying the current user's primary personal mail folders, an IMAP client displays the personal namespaces of other users who have explicitly granted access to their personal mail files to the currently authenticated user.
        Configuring IMAP internal thread use
        The IMAP service acts as an intermediary between IMAP clients attempting to retrieve messages and the IBM® Domino® mail server. IMAP clients do not have direct access to mail files on the Domino server; instead, the IMAP service acts as a proxy, relaying each client's request to retrieve messages to the mail server. To return message data to the client, Domino opens the mail database and passes on the requested information to the IMAP service. The IMAP service then sends the requested message information to the client.
        Specifying the default IMAP service greetings
        In the Server document, you can configure the ports that IMAP clients can use to connect to the IMAP service. IMAP clients can connect over a TCP/IP port or an SSL port. If you have SSL set up on the server, you can configure the TCP/IP port so that it redirects connections to the SSL port.
      - Setting up IMAP users
        To set up IMAP users, you can create a full-text index of the mail file so the IMAP user can search for information in the file.
    - Customizing mail
      After you set up basic mail routing, you can customize the IBM® Domino® messaging system to improve performance and meet the specific needs of your organization.
  - Configuring iNotes®
    IBM® iNotes® (previously IBM Domino® Web Access) provides IBM 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 IBM iNotes.
  - Configuring Web servers
    This section describes how to set up the IBM® Domino® Web server, the Domino Web Navigator, and other Web servers such as IBM HTTP.
  - 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.
