/// 使用CDO组件发送邮件CDO是Collaboration Data Objects的简称，它是一组高层的COM对象集合，并经历了好几个版本的演化，现在在Windows2000和Exchange2000中使用的都是CDO2.0的版本（分别为cdosys.dll和cdoex.dll）。CDOSYS构建在SMTP协议和NNTP协议之上，并且作为Windows2000 Server的组件被安装，您可以在系统目录（如c:\winnt或c:\windows）的system32子目录中找到它(cdosys.dll)。CDO组件相对于先前介绍的SmtpMail对象功能更为丰富，并提供了一些SmtpMail类所没有提供的功能，如通过需要认证的SMTP服务器发送邮件等。
