NETSCAPE INTRODUCES NETSCAPE MAIL SERVER FOR MESSAGING APPLICATIONS

NEW OPEN SOFTWARE PRODUCT ROUNDS OUT NETSCAPE'S SERVER PLATFORM FOR COLLABORATION APPLICATIONS

MOUNTAIN VIEW, Calif. (November 27, 1995) -- Netscape Communications Corporation (NASDAQ: NSCP) today introduced Netscape Mail Server, an open client/server messaging system that enables corporate users to exchange information easily across their enterprise networks and the Internet. Netscape Mail Server provides intuitive server management, open standards support, safe administration and extensibility to create a complete and compatible software solution for internal and external electronic mail exchange.

Seamlessly integrated with Netscape Navigator client software to enable mail reading, posting and administration from anywhere on a network, Netscape Mail Server rounds out the Netscape server software family for creating and managing online applications. In addition to the new mail server, Netscape servers include Netscape Commerce Server and Netscape Communications Server for Web-based applications; Netscape News Server for creating and serving threaded discussion groups including Usenet news groups; and Netscape Proxy Server, for increased performance on internal networks. The servers are part of Netscape's open software platform for linking people and information on enterprise networks and the Internet.

"Effective collaboration and communication are essential in today's fast-paced and decentralized work environments," said Mike Homer, vice president of marketing at Netscape. "Netscape Mail Server is a key part of Netscape's complete online solution, providing users with an open, client/server based messaging system that ideally complements Netscape Navigator 2.0's integrated mail capabilities. Users now have a full suite of Netscape servers that can be accessed through a single user-friendly client for simple and cost-effective collaboration across the Internet or within the enterprise."

Netscape Mail Server is based on technology licensed from Software.com, a pioneer in Internet infrastructure development tools that is based in Santa Barbara, California. The product provides:

• Open standards support, including support for HTML (HyperText Markup Language) and HTTP (HyperText Transfer Protocol), for compatibility with the installed base of Internet clients and servers; SMTP (Simple Mail Transfer Protocol) and POP3 (Post Office Protocol Version 3), for compatibility and interoperability with the installed base of Internet mail clients and other client/server messaging systems; and MIME (Multipurpose Internet Mail Extensions) to enable organizations to send and receive rich content through electronic mail.

• Safe administration including multiple levels of password security; user management of accounts, enabling server administrators to focus on maintaining secure account administration; user access to mail without the need to have system login accounts, which reduces the server's vulnerability to security attacks. User access can also be restricted to specific domains or hosts, enabling administrators to control which users send and receive mail through a particular system.

• Intuitive server management using online HTML forms and Netscape Navigator's point-and-click interface. Administrators can use Netscape Navigator or other Internet browsers to manage the mail server easily and remotely.

• Extensibility, enabling Netscape Mail Server to incorporate additional features not present in traditional SMTP messaging systems. For example, the server can support automatic vacation notification, distribution of special information such as company news or product updates; or return of unwanted mail for accounts which have been deactivated.

Netscape's products are based on industry standards and protocols and are compatible with the installed base of World Wide Web browsers and servers. Netscape Mail Server will be available initially for Windows NT, Sun OS and Solaris operating environments in the fourth quarter of 1995 directly from Netscape and from Netscape authorized resellers. The product will be available for other popular UNIX operating environments beginning in the first quarter of 1996. Introductory pricing from Netscape is $495.
