Mailshell's SpamCompiler Brings New Muscle to Lyris Product

SAN FRANCISCO, CA, February 10, 2005 - Lyris' MailShield Server provides highly advanced, cost-efficient mail filtering and tracking, and now includes Mailshell SpamCompiler version 3.2, which optimizes, compiles and executes more than one million filter checks in a fraction of a second. SpamCompiler technology combines a fast, compact, flexible decision tree with an intelligent, self-tuning engine.

"Our MailShield customers include major, multi-national corporations with high-volume messaging, so we needed a solution that could easily scale to their needs," said Luis Rivera, General Manager of Lyris Technologies. "Mailshell's SpamCompiler was the clear OEM frontrunner because it's extremely sophisticated, yet also lightening-fast."

Lyris MailShield Server launched in 1998 and offers administrators a wide choice of filters and rules to protect enterprise installations. MailShield Server 4.0 is available with either a Standard feature set in Windows or Solaris, or a Pro feature set for Windows. Each version incorporates Mailshell's SpamCompiler technology. The Pro version offers an extra degree of transparency by recording all SMTP transactions and providing a complete, searchable audit trail of every incoming and outgoing message.

Mailshell's SpamCompiler SDK, the embedded engine in Lyris MailShield Server, is the world's leading anti-spam engine licensed by over 20 US and International OEMs and used by more than 5,000 enterprises and 10 million consumers on over a dozen platforms. The SDK starts at 200k of code, can handle more than two million messages a day, and can be embedded anywhere in the email flow. Mailshell's OEM partners generate new anti-spam revenue, upsell existing products to new anti-spam customers, and cut anti-spam engineering and support costs to near zero.
