发送html格式的邮件

使用phplist系统给搜狐和新浪的邮箱发送html格式的邮件，邮件能够接收到并正常显示出来，但是，邮件还把html格式邮件里的文字和超链接都提取并显示了出来，为什么会出现这样的情况？使用163和qq邮件就没有出现这样的情况，大家知道这个原因能给指点一下吗？谢谢！

发送html格式的邮件void jButton8_actionPerformed(ActionEvent e) {
try
{//此段代码用来发送带有html信息的邮件

//设置邮件正文
String htmltext= " <h1> hello </h1> "+ " <a href=\ " http://www.sina.com.cn\ " target=\ "_blank\ "> click me please! </a> ";
message.setContent(htmltext, "text/html ");//text/plain设置邮件的格式因为是带有html文档的，所以用text/html格式

message.setSubject(mail_subject);
// message.setText(mail_body);在使用message.setContent()时候，好象不能用message.setText()
message.setHeader(mail_head_name,mail_head_value);
message.setSentDate(new Date());

追问

谢谢你的回答，但是我想问的是为什么搜狐和新浪的邮箱在打开html格式的邮件时，还要把html里的文字和超链接都显示一遍，其他的邮箱都能正常显示没有出现上面的问题。
