Having problem sending mail to yahoo using a yahoo id(SendMailException)

Question

Hi, I read almost all the post's related to javamail,but none of them seems to help me, and hence the reason for this post,
i've written a simple application(with reference to the one implemented on sun's site) that sends a message to a yahoo id using a yahoo id,
meaning
[email protected](recepient) and [email protected](sender)
the code is given below:
import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
import javax.mail.Authenticator;
public class MailSender
     String host = "smtp.mail.yahoo.com";
     String from = "[email protected]";
     String to = "[email protected]";
     public void sendMessage()
          try
               Properties props = System.getProperties();
               props.put("mail.smtp.host", host);
               props.put("mail.smtp.auth","true");
               Authenticator auth = new MyAuthenticator();
               Session session = Session.getInstance(props,auth);
               session.setDebug(true);
               MimeMessage message = new MimeMessage(session);
               message.setFrom(new InternetAddress(from));
               message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
               message.setSubject("Hello JavaMail");
               message.setText("Welcome to JavaMail");
               message.saveChanges(); // implicit with send()
               Transport.send(message);
          catch(Exception e)
               System.out.println("Sorry could not complete your Request, you have an error "+ e);
               e.printStackTrace();
     public static void main(String args[])     
          MailSender ms= new MailSender();
          ms.sendMessage();
     private class MyAuthenticator extends Authenticator
     public PasswordAuthentication getPasswordAuthentication() {
          return new PasswordAuthentication("someoneelse","password");
It compiles but when i execute it i get a nested exception
nested exception is:
javax.mail.AuthenticationFailedException
javax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.AuthenticationFailedException
at javax.mail.Transport.send0(Transport.java:218)
at javax.mail.Transport.send(Transport.java:80)
at MailSender.sendMessage(MailSender.java:32)
at MailSender.main(MailSender.java:45)
Does anyone know a solution to this problem?

Sure, you can put a local mail server on ur machine to test out sending and receiving in javamail. There r several mail server implementations out there, I personally prefer James (available at http://apache.org) It is pure java based mail server providing full POP3 and SMTP functionality.
Once u configure a local mail server, u can use emailids like xyz@localhost or acme@localhost
