These tests are applied to email headers and content to classify email using advanced statistical methods. In addition to this, SpamAssassin has a modular architecture which allows other technologies to be quickly wielded against spam and is designed for easy integration into virtually any email system.SpamAssassin’s practical multi-technique approach, modularity, and extensibility continue to give it an advantage over other anti-spam systems.
