How Spamato code works?

  • Hi! I am trying to understand how Spamato code works in order to make some modifications. Although, i can understand how to add my own filter i have a hard time to understand some things more about how Spamato-internals work. Where can i find some help? (even some guidance)
    * I am a postgraduate student, i have good knowledge of Java but i am not a professional programmer.
