一家大型电子邮件服务提供商需要一个高度可扩展且可用的电子邮件系统，以适应不断增加的电子邮件流量以及不断增加的电子邮件用户数量。为了降低系统开发和维护成本，要求使用现成的组件将系统模块化。在本文中，我们提出了一种基于集群的电子邮件系统架构，以实现高可扩展性和可用性以及低开发和维护成本的目标。我们采用典型的单服务器互联网电子邮件系统的内部结构，称为MTA-MDA结构，来提出系统架构以满足低成本的要求。我们使用 MTA-MDA 结构实现了四种不同的系统配置并比较了它们的性能。实验结果表明，所提出的系统架构实现了所有设计目标。
A large-scale e-mail service provider requests a highly scalable and available e-mail system to accommodate the increasing volume of e-mail traffic as well as the increasing number of e-mail users. To reduce the system development and maintenance cost, it is requested to make the system modular using off-the-shelf components. In this paper, we propose a cluster-based e-mail system architecture to achieve the goals of high scalability and availability, and low development and maintenance cost. We adopt the internal structure of a typical Internet e-mail system for a single server, called the MTA-MDA structure, to the proposed system architecture for the low cost requirements. We have implemented four different system configurations with the MTA-MDA structure and compare their performances. Experimental results show that the proposed system architecture achieves all the design objectives.
