用Java写的一个发邮件的东东(群发+多附件)。没什么好玩的了，最近看到好多地方有发邮件的东东，正好在看Java，就用Java写了，需要下载mail.jar和activation.jar，此外，用到我前次写的操作XML文件的一个类（上篇文章），好了，不多说了，代码贴贴，怎么用就看自己了：
//JavaMail中一些我们需要的类 //1.Properties
// //JavaMail需要Properties来创建一个session对象，其属性值就是发送邮件的主机，如：
// //Properties props = new Properties (); //props.put(“mail.smtp.host”, “smtp.xxxx.com”);//可以换上你的smtp主机名，就像你在OutLook中设置smtp主机名一样。
//props.put(“mail.smtp.auth”, “true”); //通过验证 // //2.Session
// //所有的基于JavaMail的程序都至少需要一个或全部的对话目标。 // //Session session = Session.getInstance(props, null); // //3.MimeMessage
// //信息对象将把你所发送的邮件真实的反映出来。 // //MimeMessage msg = new MimeMessage(session); // //4.Transport // //邮件的发送是由Transport来完成的：
// //Transport.send(msg);
