云计算平台下基于改进型DMTP的反垃圾邮件系统设计

Anti-spam system design based on improved DMTP under cloud computing platform

针对DMTP(differentiated mail transfer protocol,差分邮件传输协议)存在的类别划分模糊化问题,提出了改进型DMTP。将改进型DMTP与云计算结合,设计了云计算平台下基于改进型DMTP的反垃圾邮件系统总体模型,并详细描述了该模型中邮件传送的工作流程。通过引入对发送方类别进行判断的流程和综合云端反垃圾邮件集群系统的分析结果,该模型可以有效遏制垃圾邮件传播。最后,引用了基于Eucalyptus的反垃圾邮件系统构建模型。

This paper proposed an improved DMTP（differentiated mail transfer protocol） according to the problem that the SMTA intangible categorized in DMTP,and combined this improved DMTP with cloud computing.Then it designed an overall architecture of anti-spam system and described the work flow of mail delivery in the system in detail.By differentiating sender＇s category and integrating results from the cloud,the proposed system can effectively restrain the spam spread.Finally,it referenced an Eucalyptus-based anti-spam system.
