1 Messaging Server System Administration Overview

About Messaging Server

Oracle Communications Messaging Server is an extensible framework of cooperative modules that creates an enterprise-wide, open standards–based, scalable electronic message handling system. This system is the combination of user message and transfer agents, message stores, and access units that together provide electronic messaging.

Messaging Server provides several messaging capabilities, including:

• Message Store. Provides a modular and scalable repository of user messages.

• Message Transfer Agent. Responsible for routing, transfer, and delivery of internet mail messages. Oracle Communications Messaging Server includes a fast, scalable, and flexible MTA that replaces the Sendmail utility bundled with most UNIX systems.

• Message Access. Provides client access to messages over standard protocols IMAP and POP3. HTTP-based access is offered for web clients and Lemonade Profile 1 is supported for mobile devices.

About Messaging Server Configuration

Messaging Server provides a set of tools called Unified Configuration to configure and administer the product. Unlike in legacy configurations, Unified Configuration uses validation to verify configuration accuracy, and employs a single tool to configure the entire Messaging Server configuration (with a few exceptions). See "Overview of Messaging Server Unified Configuration" for more information.

Overview of Messaging Server Administration Tasks

A Messaging Server administrator is responsible for the day-to-day tasks of maintaining and managing Messaging Server and its users. The tasks also include managing Messaging Server components and potentially other Unified Communications Suite components.

You perform the following tasks as a Messaging Server administrator:

• Stopping and starting Messaging Server

• Managing user accounts

• Monitoring Messaging Server

• Tuning Messaging Server performance

• Migrating data to Messaging Server

• Backing up and restoring files

• Troubleshooting Messaging Server

About Messaging Server Administration Tools

Messaging Server provides the msconfig command-line utility for administering the server. See "Messaging Server Command-Line Reference" for more information. In addition, Messaging Server provides command-line utilities to manage the message store and the mail transfer agent (MTA). See Messaging Server Reference for more information.
