In addition, we also develop a formal mathematical model to study the effectiveness of DMTP in controlling spam. Through numerical experiments we demonstrate that DMTP can effectively reduce the maximum revenue that a spammer can gather. Moreover, compared to the current SMTP-based email system, the proposed email system can force spammers to...
