以下是发送电子邮件的源码，在这之前我已经从sun的网站下载了JavaMail文件和JAF文件，把里面的jar文件全放在了Classpath下
可是却产生了例外：
javax.mail.SendFailedException: Sending failed;
nested exception is: javax.mail.MessagingException: Unknown SMTP host: smtp.jspinsider.com;
nested exception is: java.net.UnknownHostException: smtp.jspinsider.com
我怀疑是这句 props.put("mail.smtp.host", "smtp.jspinsider.com");
产生了问题，可是不知道怎么改
在API文档中也没找到它的方法。
很急，希望高手们帮我解决这个问题，这里先谢了。
