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.
  - Roadmap for deploying Domino® servers
    Use this as a tool when planning how to integrate IBM® Domino® into your existing environment.
  - Planning server-to-server connections
    Servers must connect to each other to exchange data, for example to replicate databases and exchange mail. You can create connections between servers across a local area network (LAN) or wide area network (WAN), by using a pass-through server (a server that acts as an intermediary server between a client and its destination), or over the Internet. Create a Server Connection document whenever you need to establish any new or additional server connections. You can modify this document when necessary.
  - Planning directory services
    IBM® Domino® provides a range of directory service features.
  - Planning a mail routing topology
    IBM® Domino® offers you considerable flexibility in configuring your mail system infrastructure, allowing you to use IBM Notes® routing, SMTP routing, or both, for internal and external messages.
    - Connection topologies for mail routing
      Network mail routing occurs across a mix of hub-and-spoke and peer-to-peer connections.
    - Clients accessing the Domino® server
      Users who have mail files on the IBM® Domino® server can use either the IBM Notes® client or an Internet mail client to access their mail.
  - Planning a cluster
    When planning a cluster, it is important to consider the performance and ability of your hardware. The cluster must have enough CPU power, memory, and disk space to handle the cluster traffic and the number of databases and replicas required.
  - Planning the TCP/IP network
    The default TCP/IP configuration for an IBM® Domino® server is one IP address that is globally bound, meaning that the server listens for connections at the IP addresses of all NICs on the computer. Global binding works as long as the computer does not have more than one IP address offering a service over the same assigned TCP port.
  - Planning the NetBIOS network
    The IBM® Domino® network is compatible with NetBIOS, a set of IBM session-layer LAN services that has evolved into a standard interface that applications use to access transport-layer network protocols.
  - Messaging overview
    The IBM® Domino® mail system has three basic components: Domino mail servers, Domino mail files, and mail clients. The Domino mail server is the backbone of an organization's messaging infrastructure, acting both as an Internet mail server and an IBM Notes® mail server. Domino provides standards-based Internet messaging through its support of the Simple Mail Transfer Protocol (SMTP), Post Office Protocol version 3 (POP3), Internet Message Access Protocol (IMAP), and Multipurpose Internet Mail Extensions (MIME). At the same time, Domino supports Notes mail through the use of Notes routing protocols -- Notes remote procedure calls (NRPC) -- and the Notes rich text message format.
  - Planning your Notes® client deployment
    Use the references listed here to plan for, install, upgrade to, and configure the IBM® Notes® client.
  - Planning security
    An important aspect of planning security for your Domino® environment is understanding the tasks and features involved with securing each type of resource.
- 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).
- Securing
  This section describes IBM® Domino® security features, including execution control lists, IDs, and SSL.
- Administering
  This documentation provides information about the administration tools for managing and monitoring IBM Domino® servers and databases.
- Tuning
  Use this information to improve IBM® 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 IBM® Domino® server and Administrator client.

Clients accessing the Domino® server

Users who have mail files on the IBM® Domino® server can use either the IBM® Notes® client or an Internet mail client to access their mail.

By default, Notes® clients use Notes® protocols to send and access mail on a Domino® server, but a Notes® client can also act as an Internet mail client. Internet mail clients access mail files through the Domino® POP3, IMAP, or HTTP servers. POP3 and IMAP clients send mail using SMTP.

When deciding how to route local mail, keep in mind what types of mail clients you support. For example, if users have Internet mail clients, such as POP3 or IMAP, you'll need servers that can receive mail over SMTP. On the other hand, if most users send mail from the Notes® mail client, you'll want to implement Notes® routing to ensure support for Notes® public key security and features such as Notes® Document links and workflow applications.
