摘要： 提出了一种新的集群邮件服务系统DCMS。DCMS 从功能上将邮件服务划分为4 个部分：前端中转集群，服务集群，验证集群和后台存储集群，并对各个部分通过相关技术进行性能优化。测试结果表明该系统不仅具备高性能、高可用性、可伸缩性，而且易于扩展。

Abstract: The paper introduces a new E-mail system called DCMS. The DCMS is composed of four different parts in function: foreground directing cluster, service cluster, authentication cluster and background storage cluster. Experimental results show that the DCMS is highly available,highly scalable and highly extensible with high performance.
