Spamato - An Extendable Spam Filter System

Spam filter developers are confronted with the task of integrating their ideas in user-friendly products. In this paper, we introduce Spamato as an open, extendable, and multi-faceted spam filter framework. Spamato provides fundamental services commonly required by filter developers to facilitate the implementation of new approaches. Furthermore, we support email clients with add-ons to enable users to intuitively collaborate with Spamato. We also present a variety of filters and exhibit an evaluation of URL-based techniques.
