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 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.
Mailbox event notification
When the Domino® router is running in a steady state and a new message is deposited in MAIL.BOX, a copy of the message is made and placed on a mailbox event queue which is then used by a new MailEvent thread in the router. The router then uses this copy of the message without having to search MAIL.BOX to discover new messages nor perform a full note open for use in transfer or delivery. The message is cached and additional copies of this message are made as needed for multiple recipients. This router optimization prevents creating extra copies of the note.

- 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.
      - Mailbox event notification
        When the Domino® router is running in a steady state and a new message is deposited in MAIL.BOX, a copy of the message is made and placed on a mailbox event queue which is then used by a new MailEvent thread in the router. The router then uses this copy of the message without having to search MAIL.BOX to discover new messages nor perform a full note open for use in transfer or delivery. The message is cached and additional copies of this message are made as needed for multiple recipients. This router optimization prevents creating extra copies of the note.
      - Starting, stopping, and restarting the mail router
        By default, when you start the server, the Router task automatically loads and starts. You can manually shut down and restart the Router to troubleshoot server and messaging problems. You can also disable automatic loading of the Router.
      - Recalculating the server's routing table
        The Router on each server maintains a dynamic routing table, which specifies the best route to each possible destination server. The routing table builds on information contained in the server's NOTES.INI file and in the Configuration Settings, Domain, Connection, and Server documents in the Domino® Directory.
      - Routing mail on demand to a specific server
        You can route mail to another Domino® server between scheduled intervals, forcing all mail in the transfer queue of the specified server to route immediately.
      - Using Domain documents
        Domain documents define the domains used in mail routing.
      - Routing internal mail
        Internal mail consists of messages sent between users within an organization and its local Internet domains. The Domino® mail router (the Router) uses both SMTP and Notes® routing to transfer messages between network servers, and handles messages in both MIME format and Notes rich text format. By default, the Router transfers local mail using the Notes routing protocol only. Within a given Notes named network, servers that use Notes routing automatically transfer mail among themselves.
      - Creating a Configuration Settings document
        Use the Configuration Settings document to set up LDAP, mail, mail routing, and MIME on an IBM® Domino® server. You can also use this document to edit settings in the NOTES.INI file. A Configuration Settings document can define settings for all of your Domino servers in one IBM Notes® domain, for the servers in one specific group, or for one individual server.
      - Configuring Domino® to send and receive mail over SMTP
        Setting up an IBM® Domino® server as an SMTP server consists of enabling two separate tasks: a listener task and a routing task. Enabling the SMTP Listener allows a server to receive mail over SMTP. Enabling SMTP routing lets the Domino Router send mail to other servers using SMTP.
    - 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.
    - 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.
- Securing
  This section describes IBM® Domino® security features, including execution control lists, IDs, and SSL.

Mailbox event notification

When the Domino® router is running in a steady state and a new message is deposited in MAIL.BOX, a copy of the message is made and placed on a mailbox event queue which is then used by a new MailEvent thread in the router. The router then uses this copy of the message without having to search MAIL.BOX to discover new messages nor perform a full note open for use in transfer or delivery. The message is cached and additional copies of this message are made as needed for multiple recipients. This router optimization prevents creating extra copies of the note.

You can use NOTES.INI settings to limit the amount of memory used by open notes. The memory values are shared and maintained by mailbox event generation and any open router note.

For the following two NOTES.INI settings, RouterMaxEventMemorySizeBytes and RouterMaxEventMessageSizeBytes, if either of the maximum values specified are reached, the router falls back and searches mailboxes for new messages. New messages located during the search are not cached in the main message queue.

RouterMaxEventMemorySizeBytes

Memory limit for event generation.

The default setting is null, but when Domino® encounters a null value for this setting, it sets the value to equal the NSF buffer pool size divided by 5.
0 -- Disables the setting.

RouterMaxEventMessageSizeBytes

Maximum message size for any one message allowed to be copied and placed on the mailbox event queue.

The default value is null but when Domino® encounters a null value for this setting, it sets the value of 10000000 bytes (10 million bytes).
0 -- Disables the setting.

The following two NOTES.INI settings, RouterMaxQueueMemorySizeBytes and RouterMaxQueueMessageSize Bytes, provide limits for caching these notes in the main message queue for immediate use in delivery or transfer.

RouterMaxQueueMemorySizeBytes

Memory limit for main message queue caching of the note passed via mailbox event generation.

The default setting is null, but when Domino® encounters a null value for this setting, it sets the value to equal the NSF buffer pool size divided by 5.
0 -- Disables the setting.

RouterMaxQueueMessageSize Bytes

Message size limit for main message queue caching of notes.

The default value is null but when Domino® encounters a null value for this setting, it sets the value of 10000000 bytes (10 million bytes).
0 -- Disables the setting.
