电子邮件E-mail是Internet最基本的和最重要的服务之一。据统计,Internet上百分之三十以上的业务量是电子邮件。由于我国的通讯基础设施较差,网络速度较慢,因而,与Internet其它功能如WWW、FTP、News等相比,电子邮件服务具有更大的实用性。《CINNIC中国互联网络发展状况统计报告(2000年1月)》中指出,71.65％的中国用户最常使用的网络服务就是电子邮件,这个比例远远高于搜索引擎(50.40％)和软件上传或下载服务(44.16％)等其它服务。本专题为电信运营商、ISP、ICP、企业用户在构建邮件系统时如何选择服务器端的系统软件提供参考。专题涉及的三个大容量邮件系统——亚信AIMC、世纪鼎点的鼎点飞鸿、世纪永联的For-mail系统是目前国内有代表性的系统。
E-mail is one of the most basic and important services on the Internet. According to statistics, more than thirty percent of the business volume on the Internet is e-mail. Due to the poor communication infrastructure in our country and the slower network, e-mail service is more practical than other Internet functions such as WWW, FTP, News, and so on. “CINNIC Statistical Report on the Internet Development in China (January 2000)” states that 71.65% of Chinese users use the most commonly used Internet service as e-mail, which is much higher than that of search engines (50.40%) and software uploads Download service (44.16%) and other services.
