N-PLEX GLOBAL™ Internet Server for Large Organizations and Service Providers N-PLEX Global is a scalable, high-performance Internet server software solution designed for commercial service providers and large organizations with high-end messaging requirements. N-PLEX Global features a distributed message store architecture that handles millions of users across multiple servers within a single domain. This distributed architecture provides maximum performance and reliability for multiple servers clustered in a central location, or geographically distributed across multiple locations. The Manage Service Provider Solution Developed with a strong emphasis on management and security, N-PLEX Global addresses the specific requirements of service providers and organizations with high-volume messaging environments. The centralized administration interface, called the ISOCOR Management Center, is easy to use, yet provides sophisticated capabilities that include multi-level system administration, message store management facilities, message filtering, performance monitoring, and message archiving. For managing multiple servers, N-PLEX Global has extensive remote management facilities for installation and upgrade of software components, configuration, stopping and starting of services, log file analysis, and SNMP monitoring. Additionally, Web-based administration utilities allow users and administrators to perform simple routine tasks from a standard Web browser. For simplified management of mailing lists, a List Management Agent allows users to easily subscribe to or delete themselves from mailing lists. Scalable, High-Performance Messaging N-PLEX Global features a multi-threaded architecture that natively supports the latest Internet standards for SMTP, MIME, POP3, IMAP4, HTTP, and LDAP. The scalable architecture allows you to easily expand your environment with additional servers and components. N-PLEX Global consists of the following core components: High-Performance Internet (SMTP) Mail Server. Allows fast, reliable handling of incoming and outgoing messages. Multiple servers may be configured in clusters to distribute messaging traffic. Distributed POP3/IMAP4 Message Store. Robust, large-scale message store seamlessly supports both POP3 and IMAP4 clients simultaneously across multiple servers in a distributed configuration. Directory Services. Powerful, high-speed LDAP Directory server and X.500-compliant Directory services access user addresses and routing information. Directory information is easily accessible via LDAP, X.500, and HTTP using a standard Web browser. A number of product options are available to extend the functionality and capabilities of N-PLEX Global, including server-based virus scanning to enhance the integrity of the user environment. Virtual Private Network N-PLEX Global allows you to create a virtual private network within a service provider or large corporate environment. Within this virtual private network, you can establish administration and access rights on a per-domain basis. Subscribers can manage user accounts and perform routine administration tasks without assistance from the service provider. Additional virtual private network features and services can also be incorporated to provide enhanced value-added services. High Performance Internet Mail Server N-PLEX Global features superior message handling with an Internet Mail Server (SMTP MTA) designed for fast, high-volume switching of incoming and outgoing messages. The Internet Mail Server accepts incoming messages, looks up user routing information in the Global Directory Server, and routes the messages to the appropriate message store. The Global Directory Server contains user names, addresses, and other relevant information. The Internet Mail Server uses DNS or static routing information, as configured by the administrator in the ISOCOR Management Center, to relay outgoing messages and deliver them to remote hosts. You can also configure N-PLEX Global as an application gateway firewall. This allows you to filter incoming SMTP messages and limit access by IP address. For example, you can configure the server to exclude a list of addresses to help prevent unsolicited e-mail (spamming) and enhance access control. Distributed POP3/IMAP4 Message Store N-PLEX Global features a robust, large-scale message store designed to handle millions of users, distributed across a large number of messaging servers, within a single domain and across multiple domains. The integrated POP3/IMAP4 message store enables simultaneous access and transparent migration of POP3 and IMAP4 clients, and supports encryption for authenticating users. The IMAP4 features include synchronization with off-line mobile clients, extensive text searching facilities, and shared folder support. Global Directory Services N-PLEX Global utilizes a common directory called the Global Directory Server that stores user addresses, provides routing information, and unifies the components in the environment. The Global Directory Server supports LDAP for directory access and features an X.500-compliant Directory that provides high-speed access to users, message routing information, and other relevant directory information. Alternatively, you can use the integrated LDAP Internet Directory server for storing user names and addresses in environments where a distributed message store configuration is not needed or implemented. The Global Directory Server uses the following protocols to provide a distributed directory service: LDAP for client access, DAP (Directory Access Protocol) for N-PLEX Global routing information, DSP (Directory System Protocol) for forwarding requests to remote directory servers and obtaining results, DISP (Directory Information Shadowing Protocol) for replicating information between servers, and HTTP for access from Web browsers. The Web/Directory gateway facilitates access to LDAP and X.500 Directory information from a standard Web browser, and utilities allow you to import and export data to other applications, including user registration from other mail systems. Flexible, Global Enterprise Configurations For extended configurations, you can use N-PLEX Global with other server solutions in the N-PLEX Product Family: N-PLEX Office for small businesses and organizations, N-PLEX Enterprise for corporate Internet/intranets, and N-PLEX Hub for connectivity and integration of heterogeneous mail environments. For service providers and telecommunications organizations, the extensive management capabilities provide value-added system administration services. The unique remote management features of the N-PLEX Product Family allow you to install N-PLEX Office and N-PLEX Enterprise in a CPE (Customer Premises Equipment) configuration and centrally manage them with N-PLEX Global. This configuration allows N-PLEX Office and N-PLEX Enterprise to reside in remote office locations and minimizes system administration requirements. Reliable, Available Messaging Services N-PLEX Global is designed to ensure continuous availability and data consistency. To enhance system availability and prevent interruption of service, you can implement fault-tolerant configurations for your environment, such as disk mirroring and redundant servers. The Global Directory Server also allows fully redundant configurations with automatic replication of directory contents in the event of system failure. A database backup and restore utility with a roll-back and roll-forward feature quickly recovers data and restores data integrity. N-PLEX Global servers can be monitored from other management centers that use SNMP, allowing integration with existing network monitoring for routers and other network components. Application Programming Interfaces ISOCOR offers APIs and protocols separately, to allow customization of N-PLEX Global and integration with other applications and systems. Submission API. Enables platform and language-independent Internet mail access. Message Filtering API. Provides filtering and processing of SMTP messages by another program. Mail Agent API. Allows the development of mail agents to carry out actions described in the message and return results in a reply message. Gateway API. Enables the attachment of external gateways for message conversion. Additionally, PLEXLINK POP3 Provider, a MAPI POP3 service provider, enhances the ability of N-PLEX servers to integrate into existing environments where proprietary MAPI-based mail clients may be in use. This provides POP3 connectivity for clients such as Exchange, Outlook™, cc:Mail&REG, and GroupWise™.
