SpamScope (https://github.com/SpamScope/spamscope) is a fast and advanced tool for email analysis developed by Fedele Mantuano (@fedelemantuano). The analysis engine it’s based on Apache Storm and Streamparse.
Why use Apache Storm?
Apache Storm works with streams, and in this case we analyze a stream of email messages. Apache Storm allows you to start small and scale horizontally as you grow. Simply add more workers, that can be on different hosts.
An application is designed as a “topology” in the shape of a directed acyclic graph (DAG) with spouts and bolts acting as the graph vertices.
