The spam protection systems used today only filter spam from the user’s inbox (i.e. recipient’s edge), but the spam already travels the network, and provokes non-negligible cost to network operators in terms of bandwidth and infrastructure. On the other hand, content-based filtering, one of the most widely adopted defense mechanism, has turned spam problem into false positive and negative one. In consequence, this makes email delivery unreliable. | The spam protection systems used today only filter spam from the user’s inbox (i.e. recipient’s edge), but the spam already travels the network, and provokes non-negligible cost to network operators in terms of bandwidth and infrastructure.
