CUPERTINO, Calif. - June 2, 2003 - Symantec Corp.

Symantec Mail Security for Microsoft Exchange offers one-pass scanning of email content for inappropriate material and delivers enterprise customers comprehensive protection, detection and removal of security threats on Microsoft Exchange 2000 servers. For a preview of the solution, visit Symantec at booth #842.

"Symantec is providing its enterprise customers with a mail security solution that gives them more confidence in protecting their Exchange environment," said Kevin McCuistion, director of Exchange marketing at Microsoft Corp. "We're pleased to work with Symantec in providing security solutions that meet the varying needs of enterprise customers."

"Symantec understands how critical Exchange servers are to corporations and is committed to providing security solutions that keep them up and running," said Lily De Los Rios, vice president, product delivery and response, Symantec Corporation. "Symantec Mail Security for Microsoft Exchange provides corporate administrators with an integrated mail security solution that is easy to configure and manage and will not slow down system performance."

The fast, scalable solution can be centrally managed from a single console and is backed by Symantec Security Response, the world's leading Internet security research and support organization.

Symantec Mail Security for Microsoft Exchange, formerly named Symantec AntiVirus/Filtering for Microsoft Exchange, is designed to provide the highest scanning performance and protection with the lowest impact on server performance. The solution includes the following new and enhanced features:

• Enhanced Spam Prevention -- Supports all third party DNS-based Real-time Blacklists or RBLs (e.g. MAPS, spamhaus.org and orbd.org). Enterprises can use multiple blacklist services at the same time to stop spam based on different sources. Suspicious e-mail can be tagged as spam by adding a text prefix to warn of possible spam without deleting valid email.



• Enhanced Content Filtering -- Incorporates flexible and intuitive filtering rules to stop unwanted content from entering the network and prevent confidential information from leaving the network. Scans suspicious files and attachments. Allows administrators to set rules specifically for scanning inbound email versus both internal and external email, saving time and preserving bandwidth. Also utilizes Symantec's patented Dynamic Document Review (DDR) heuristic technology to automatically block objectionable content.



• Enhanced Virus Protection -- Provides enhanced protection against viruses, worms, Trojan horses, and blended threats. Purges mass mailer worms prior to reaching end-users, minimizing helpdesk calls and saving storage space. Proactive outbreak feature detects virus outbreaks in the early stages and automatically quarantines suspicious messages.
