Netscape Mail Server 2.0 is the next generation of an open standards-based client-server messaging system that provides superior administration, scalability, performance, security and remote connectivity. Netscape Mail Server is seamlessly integrated with Netscape Navigator and many other messaging clients, creating a turnkey messaging system at the core of an intranet environment.

Companies have traditionally made investments in "islands" of messaging systems which were made interoperable through a patchwork of gateway solutions. Administration is always problematic by such an approach and the messages are often modified during transmission if not lost altogether. Consequently, an organization's communications with trading partners and customers is often compromised. More important, with the lack of scalability and performance limitations of such communications networks, a customer's costs of ownership skyrocket. While a number of vendors are promising open standards-based solutions on their client, their infrastructures tend to be proprietary, slow, and difficult to integrate with other Internet applications. Netscape Mail Server was developed to overcome all of these problems.

Netscape Mail Server is a full-featured message transport engine built to the open standards of the Internet. It includes features to:

  • support remote, sometime-connected clients
  • significantly improve the cost of ownership by supporting thousands of users per server
  • transmit messages reliably and efficiently
  • enhance the security of any intranet/Internet messaging system
  • integrate seemlessly with existing Web technology investments

Netscape Mail Server is a native SMTP/MIME system which allows it to interoperate with any other SMTP-compliant messaging system or gateway. By using Netscape Mail Server as an integral component of their messaging backbone, companies are assured faster message delivery and higher message content quality. Netscape Mail Server integrates seamlessly with Netscape SuiteSpot's intuitive, integrated network management services.

Netscape Mail Server, when coupled with Netscape Directory Server, provides companies with a scalable, high-performance messaging and directory services intranet/Internet solution.


Employees who travel and need to access the corporate network have often been overlooked when it comes to messaging solutions. Mail users want the support for controlled downloads and slow modems. Netscape Mail Server provides solutions for these and other problems by supporting remote connected users through the Internet Message Access Protocol Version 4 specification (RFC 1730). Features supported via this protocol include:
  • create, delete, and rename mailboxes
  • check for new messages
  • permanently remove messages
  • search messages
  • selectively fetch messages all or portions of:
    • message headers
    • message contents

Through these features, Netscape Mail Server provides

a rich, yet fully managable alternative to proprietary remote messaging solutions. Customers are able to deploy the upcoming IMAP4 enabled release of Netscape Navigator or any other IMAP4 client to take advantage of the Netscape Mail Server's support for remote connectivity.

Netscape Mail Server's innovative client-server implementation delivers performance that is several times greater and more scalable than most messaging systems. As information being transmitted over Internet/intranets becomes increasing complex, customers are looking for messaging solutions that will grow as their business grows. Netscape Mail Server easily supports the load and throughput requirements of today's intranet/Internets.
  • Netscape Mail Server delivers unparalleled scalability compared to traditional file-sharing messaging systems. Thousands of users can be supported from a single machine, unlike file-sharing systems which can only support 100 users per post office. Netscape Mail Server's scalability significantly reduces the cost of ownership and provides a messaging solution which will painlessly grow as needed.
  • Netscape Mail Server outperforms other file-sharing and client-server messaging systems in its processing of messages, message queue, and directory lookups. As a company increases the quantity and size of messages transmitted through its network, they need not worry about whether the Netscape messaging system will be able to handle the traffic.

Business communications are the backbone of any organization, and companies need to be assured their Internet-based solution is secure. Netscape Mail Server has numerous features to ensure messaging system security. These features include:
  • SSL 3.0 support. Netscape Mail Server supports Secure Sockets Layer (SSL) 3.0 in its administration system. This ensures the management of a messaging system is uncompromised by attacks from the network. More important, through SSL 3.0, companies can manage the messaging server from any point on the network, securely.
  • S/KEY single-session key. With S/KEY, a dynamic single session key is generated to encrypt client-server communications. Companies do not have to worry that their user passwords are being transmitted in clear text on the network when POP3 or IMAP4 clients connect to the mail server over the network.
  • Multiple levels of password security. Administrators can set separate passwords for system configuration, account changes, and message retrieval. Organizations are able to deploy and manage Netscape Mail Server enterprise-wide through a password hierachy that matches their organization.
  • Minimally privileged process. Netscape Mail Server runs with minimum privileges. By reducing the privileges associated with the application, Netscape Mail Server reduces the risk of security break-ins.
  • Users are stored in a separate database. The server does not require users to have system log-in accounts to send and receive mail. Companies need not fear that the integrity of their intranet will be compromised by this traditional break-in strategy.
  • Restricted access. Administrators can control which domains or hosts can send and receive email.

Netscape Mail Server conforms to open Internet standards, enabling wide interoperability with other mail systems. Customers will not have to force fit Netscape Mail Server into an established messaging network. In fact, by natively supporting all of the popular Internet protocols for messaging, Netscape Mail Server allows customers to integrate an easily manageable, high-quality solution as the cornerstone of their messaging network. The standards Netscape Mail Server supports include:
  • HTTP (HyperText Transfer Protocol) 1.0 - for compatibility with any HTTP-compliant clients or servers.  By supporting HTTP (and HTML) Netscape Netscape Mail Server allows customers to manage their Netscape Mail System from any forms-capable Web client on the Internet.
  • SMTP (Simple Mail Transfer Protocol) - for interoperability with other messaging systems that support Internet mail. With native SMTP support, customers are assured of consistent success when transmitting messages to other Internet-compliant mail systems.
  • MIME (Multipurpose Internet Mail Extensions) - so users can send and receive messages with rich content types. Netscape Mail Server supports a large number of MIME data types, including HTML. Organizations can Netscape Mail Server can transmit JavaScript-enabled HTML forms between users and have the forms executed in each user's mailbox. For example, this functionality can be used to distribute HR information and software updates without any other specialized software.
  • IMAP4 (Internet Mail Access Protocol Version 4) - for remote connectivity features (off-line usage, partial downloading of messages, and mailbox synchronization) from an Internet messaging network.
  • POP3 (Post Office Protocol Version 3) - enables Netscape Mail Server to be used with many email clients such as Zmail, Eudora Pegasus Mail, and Microsoft Exchange.

Netscape Mail Server's setup and administration is easy, as it can be performed using HTML forms and Netscape Navigator's point-and-click user interface.
  • Integrated with Netscape Navigator. Administrative functions are simplified through HTML (or email) forms, allowing the administrator to use Netscape Navigator to manage the system. There are no configuration files to edit by hand, greatly simplyfing the administration of the system.
  • NIS/NIS+ integration. Integration with Network Information Servers in the resolution of message addresses allows Netscape Mail Server to take full advantage of all the available information in a network.
  • Easy importing. User accounts are easily imported from existing sendmail servers.
  • Multiple domains. The server handles multiple domains on a single machine.
  • User-managed accounts. End users manage aspects of their accounts, including passwords, auto-replies, and auto-forwards. Administrators are relieved of the burden of managing all of the user's account information while still maintaining the secure account information.
