Aladdin Systems Licenses Mailshell Spam Filter for Global Retail Distribution

WATSONVILLE, CA - October 8, 2003 - Aladdin Systems, Inc., an Aladdin Systems Holdings, Inc., company (OTC BB: ALHI), today announced that it will publish SpamCatcher, a desktop spam-filtering program developed by Mailshell Inc., the leading OEM provider of anti-spam software. Aladdin also licensed Mailshell's software developers' kit to create additional SpamCatcher products for other languages and platforms.

"We looked at the top anti-spam providers and selected Mailshell for its ease of use, superior technology and proven customer satisfaction," said Jonathan Kahn, president of Aladdin Systems Inc. "Licensing Mailshell's engine will allow us to develop customized products for each vertical and geographic market, while leveraging a proven, award-winning core technology."

Mailshell's anti-spam engine is deployed at more than 300 enterprises and by thousands of consumers. It identifies spam by using more than a thousand spam-blocking rules, including pattern matches, heuristic functions, and proprietary and third party databases. Complex algorithms are applied to compute the probability that each piece of e-mail is spam. The Mailshell Engine also creates a fingerprint ID for every e-mail message and uses it to continuously analyze new spam, create new rules and adjust the weighting of existing rules. Since spam constantly evolves, customers can opt to receive scheduled or real-time rules updates.

"Aladdin's expertise as a software publisher and marketer will quickly bring SpamCatcher to the attention of millions of people worldwide," said Tonny Yu, president of Mailshell. "Aladdin is an ideal OEM partner for us given its strong global network of retailers."

SpamCatcher 3.0 is available for a suggested retail price of $29.99 from retail, catalog, and online channels.
