The Abaca CLX Anti-spam Solution is flexible enough to fit into any service provider's infrastructure and supports a variety of system architectures.

Fully redundant deployment is easily accomplished to ensure reliable and consistent service delivery.

"Service providers are under constant attack by spammers, and the volume of spam continues to grow," said Bill Kasje, Vice President Business Development of Abaca Technology Corporation. "The unmatched accuracy and scalability of the Abaca CLX Anti-spam Solution requires fewer servers to support hundreds of millions of users reducing the power footprint, saving rack space, and minimizing system administration costs. In addition to saving invaluable resources Abaca's solution also increases customer satisfaction helping to improve loyalty and retention for email service providers."

The proprietary and patent-pending technology behind the Abaca CLX Anti-spam Solution, ReceiverNet[TM], uses receiver reputations to filter spam. Using the receiver's reputation to determine the likelihood that incoming messages are legitimate or not, ReceiverNet enables the Abaca CLX Anti-spam Solution to effectively block a minimum of 99.9 percent of spam, along with viruses and phishing attacks. The system learns and updates itself by the real-time tracking of the ratio of spam versus legitimate email for each Abaca protected email user, making spam detection even more accurate as email users join the Abaca ReceiverNet Network.
