try{

request.setCharacterEncoding("gb2312");

String from=request.getParameter("jname");

String to=request.getParameter("sname");

String subject=request.getParameter("title");

String messageText=request.getParameter("message");

String password=request.getParameter("password");

String S =request.getParameter("jname");

int n =S.indexOf('@');

int m=S.length() ;

String server =S.substring(n+1,m);

//建立邮件会话

Properties pro=new Properties();

pro.put("mail.smtp.host","smtp."+server);

pro.put("mail.smtp.auth","true");

Session sess=Session.getInstance(pro);

sess.setDebug(true);

//新建一个消息对象

MimeMessage message=new MimeMessage(sess);

//设置发件人

InternetAddress from_mail=new InternetAddress(from);

message.setFrom(from_mail);

//设置收件人

InternetAddress to_mail=new InternetAddress(to);

message.setRecipient(Message.RecipientType.TO ,to_mail);

//设置主题

message.setSubject(subject);

//设置内容

message.setText(messageText);

//设置发送时间

message.setSentDate(new Date());

//发送邮件

message.saveChanges(); //保存邮件信息

Transport transport =sess.getTransport("smtp");

transport.connect("smtp."+server,from,password); //这一句很关键，相当于登陆管理员邮箱来发邮件// transport.connect("",wode@,"123456");

transport.sendMessage(message,message.getAllRecipients());

transport.close();

out.print("发送邮件成功");

}catch(Exception e){

out.print("发送邮件失败,原因可能是
