The rapid growth of the Internet and corporate intranets and extranets call for new messaging scaling requirements while supporting a broad range of user types. Oracle9i Application Server Email gives service providers, large enterprises, and online commercial applications an open, secure, massively scalable, distributed object network architecture that can accommodate explosive growth while providing highly reliable messaging services. 

Background
Electronic mail solutions historically were proprietary. Users were required to operate proprietary clients working in conjunction with proprietary mail servers, communicating with proprietary protocols. The explosive acceptance of the Internet has standardized electronic mail solutions. This allows Oracle to exploit its strengths in providing scalable, reliable mail servers with a high quality of service. 
 

Highly Flexible, Scalable Architecture 
Oracle9iAS Email is designed to grow to almost any size while maintaining its performance and ease of administration. You can customize your Oracle9iAS Email system based on the number of messages you need to store, how many users will access the system under peak loads, and how many messages will be sent and received over a time period. Oracle9iAS Email's unique N-tier Internet computing architecture allows you to support thousands of users on a single piece of hardware, if necessary.  You have the option of creating a two-tier system with a single host supporting a few thousand users, or a three-tier system where the protocol access servers are separated from the message database supporting several thousand users. This architecture allows you to add hardware at any tier, virtually expanding to support an unlimited number of users. 

Flexible Oracle9iAS Email architecture 
 

Open Standards-Based Messaging 
Oracle9iAS Email lets users access their messages with the messaging client of their choice. Messages can be accessed using any Internet Message Access Protocol version 4 (IMAP4)- or Post Office Protocol version 3 (POP3)-compliant client such as Netscape Messenger, Microsoft Outlook Express, or Eudora Pro Lite.  Oracle9iAS Email also supports any SMTP-compliant message transfer agent.  And Oracle9iAS Email provides directory services with any directory that is compliant with the light-weight directory access protocol (LDAP) standard, such as Oracle Internet Directory. 
 

Oracle8i-based Message Store 
Oracle9iAS Email stores messages and attachments in an Oracle8i-based message store. Oracle8i, the world's leading information management platform, enables Oracle9iAS Email to offer unmatched data availability, data integrity, low recovery time, and fault-tolerance capability.  Oracle9iAS Email takes advantage of Oracle 8i's multithreading, parallel processing, high availability support, and high performance so thousands of users can run with rapid response times. 
 

Server Side Rules
Oracle9iAS Email's server side rules can be used to set up automatic filters that can be performed on all incoming messages, for multiple users, independent of client. With email messages stored as relational data, this mechanism allows other database applications to easily apply consistent database transaction logic to both mail data and external data. 
 

Integration With Other Applications 
PL/SQL programmers can create custom application interfaces to integrate Oracle9iAS Email with other applications.  Oracle9iAS Email PL/SQL packages enable applications to directly manipulate stored messages as well as create MIME-standard outgoing messages.  Combined with server side rules, applications integrated with Oracle9iAS Email have a powerful means to efficiently process and manage an increasing number of email messages. 
 

Thin Client
Oracle9iAS Email  5.2 provides a customizable thin client based on Oracle9i Application Server that enables service providers and enterprises to give their users access to their email through a web browser. Users thus do not even need a standard email client to access their messages. 
 

Enhanced Administration Features 
Oracle9iAS Email 5.2 contains some important new features for administrators that ease management of messaging servers in the changing market. 

• Monitor Charts 
  Administrators of Oracle9iAS Email  5.2 can graph the size of queues, number of concurrent connections, the sum of messages sent and received, and other statistics about an installation. 

  Virus Cleanup Tool 
  New email-borne viruses crop up all the time, so it is impossible to filter them all out as they come in. Oracle9iAS Email's virus cleanup tool augments a site's MTA virus scanner. An administrator can simply define the fingerprint of a new virus in the virus cleanup tool to check messages that have already entered the system. Any messages matching that fingerprint can then be set aside into a separate queue for closer review and processing. 

  OFA Compliance 
  Multiple instances of Oracle9iAS Email 5.2 can be supported on one Oracle database server. This provides Internet Service Providers and enterprises with more flexibility in setting up their system architectures. 

Performance Enhancements 
Oracle9iAS Email 5.2 contains performance enhancements that support the needs of growing numbers of users on enterprise and hosted systems. 

• Speedier Email Delivery 
  The protocol servers (IMAP4, POP3, and SMTP Gateways) of Oracle9iAS Email 5.2 are enhanced to perform a directory lookup in order to directly deliver emails or log into the correct email node. This enhances performance of message delivery to a large number of users in large installations. This also provides Oracle9iAS Email with the ability to support multiple back end databases and domains behind a common protocol server. 

  Dedicated Sorting Postman 
  Administrators of Oracle9iAS Email 5.2 can set up a Postman process dedicated to sorting higher priority messages. Use of dedicated sorting Postmen processes could speed delivery of high priority emails when queues are large. 

Unified Messaging
Oracle9iAS Email 5.2 works with Oracle9iAS Unified Messaging 2.1.2 to provide users with access to voicemail and faxes through their Oracle9iAS Email Inbox, for a true messaging solution. Oracle9iAS Unified Messaging users can also retrieve their voicemails and emails from their telephones. For more information on Oracle9iAS Unified Messaging, read the Unified Messaging Feature Overview. 

Oracle9iAS Email: The Messaging Solution 
Oracle9iAS Email is a highly scalable, open standards-based solution for providing electronic messaging services to support the current and future electronic messaging needs of growing companies, large enterprises, and service providers. Oracle9iAS Email uses the power and scalability of the Oracle 8i database to store and process emails. Furthermore, customers can email-enable applications by integrating them with Oracle's customizable, flexible messaging system using Oracle9iAS Email's PL/SQL application programming interfaces.
