Abaca(R) Unveils Breakthrough Approach in the Fight Against Spam.

Email Protection Gateway([TM]) Guarantees 99 Percent Accuracy for Small to Medium Businesses

SAN JOSE, Calif. -- Abaca Technology Corporation, an innovator in email protection and messaging security, today announced a new anti-spam technology for small to medium businesses that delivers the highest accuracy rate in the industry. Based on a sophisticated algorithm that uses receiver reputation to precisely differentiate spam from legitimate messages, Abaca's breakthrough solution is designed to achieve a 99 percent spam catch rate with less than one false positive in 20,000 emails.

"Many people regard the email security industry as already overcrowded," said Steve Kirsch, founder, chairman of the board, and chief executive officer of Abaca Technology Corporation. "However, we're not just another entrant using the same ineffective technologies everyone else does. Abaca's approach to spam filtering is novel, simple, and highly effective. We are first to market with a disruptive new technology that virtually eliminates spam--and we are offering it at a price point that is extremely competitive for small to medium businesses."

The core of Abaca's Email Protection Gateway is ReceiverNet[TM], a proprietary, patent-pending technology that works in any language and protects against existing and future spam techniques. ReceiverNet operates on the principle that an email message is more likely to be legitimate if it is sent to recipients that typically receive a low percentage of spam. Conversely, an email message is more likely to be spam when sent to recipients that typically receive a high percentage of spam. ReceiverNet rates messages based on each user's overall ratio of legitimate messages to spam messages.

By using the receiver's reputation to determine the likelihood that incoming messages are legitimate or not, ReceiverNet is designed to enable Abaca's Email Protection Gateway to effectively block 99 percent of spam, as well as viruses and phishing attacks. The solution automatically updates its own software and definitions, requiring near-zero system administration once it is installed.

"What a fantastic product!" said customer Steve Taffee, director of technology at Castilleja School in Palo Alto, California. "Since 2005 the email protection solution has been consistently filtering at rates above 99.9 percent. We have nothing but praise for the solution and the company."

99 Percent Accuracy--Guaranteed

Abaca is the latest brain child of legendary entrepreneur Steve Kirsch, who previously founded Frame Technology, which was acquired by Adobe Systems, and Infoseek, which was acquired by The Walt Disney Company. Personally frustrated by the proliferation of spam, Kirsch spent several years developing a sophisticated algorithm that would ensure near-perfect spam protection. The result is Abaca's Email Protection Gateway, which, combined with the company's ReceiverNet Service, is designed to deliver 99 percent accuracy in spam blocking.

Unlike anti-spam solutions whose blacklists and whitelists quickly become outdated, ReceiverNet continues to learn and gain in accuracy as it tracks spam statistics for each user added to the ReceiverNet network. Abaca's solution is so accurate, in fact, that the company guarantees 99 percent results for its customers.

"Kirsch has a track record of designing simple things that work really well, and he's done it again," said Spam Filtering Guru Gordon V. Cormack. "ReceiverNet is a clever technique that eclipses the more complex, intrusive, and less effective methods in use today."

"No other vendor stands behind their product like we do. We offer a performance guarantee that sets us apart from our competitors. The average spam-blocking rate for small to medium businesses is only 80 percent. Our product is guaranteed to deliver at minimum 99 percent accuracy," added Kirsch.
