WOBURN, Mass. - July 31, 2006 - Reflexion Networks, a hosted service provider of anti-spam and email security solutions, today announced that it has integrated award-winning SpamCompiler technology from San Francisco-based Mailshell Inc, the OEM anti-spam leader, into its advanced Reflexion Total Control (RTC) technology.

"The broad array of capabilities is highly configurable for different user needs, and can be deployed by service providers and email administrators in a simple, set-and-forget fashion."

Reflexion blends Mailshell's capabilities with supplemental address technology, whitelisting, content filtering, and inbound and outbound virus filtering in a hosted solution that provides accurate, proactive protection that is maintenance free. Users enjoy unparalleled control over access to their inbox, ensuring uninterrupted access for legitimate senders, along with other capabilities that enhance the email experience, such as the detection of address sharing and the use of topic-specific addresses for tracking communications.
