I am using java mail bean to send a email & I am receving this
error message

javax.mail.SendFailedException: Sending failed; nested exception is: javax.mail.SendFailedException: Invalid Addresses; nested exception is: javax.mail.SendFailedException: 553 sorry, Authentication failed or timed out. Please do get messages first to authenticate yourself.(#4.4.3)

I have used a mail bean the code of which is given below



import java.*;
import sun.net.smtp.SmtpClient;
import java.io.*;
import java.util.Date;

public class mailbean {

public void send (String to, String from, String sub, String mes) {
try{
Date dt = new Date();
SmtpClient client = new SmtpClient(" ");
client.from(from);
client.to(to);
PrintStream message = client.startMessage();
message.println("From: " + from);
message.println("To: " + to);
message.println("Sent: " + dt);
message.println("Subject:"+sub);
message.println();
message.println(mes);
message.println();
client.closeServer();
}
catch (IOException e){
System.out.println(e);
}
}

}

This code was working fine before. We have changes our mail server to rediff. When I am replacing the old smtp addrress with the new one I am getting the above error.
I would request someone of you to provide a solution for this .
Thanks a lot in advance for the solution

Welcome to JavaRanch!

We're pleased to have you here with us in the JSP forum, but there
are a few rules that need to be followed, and one is that proper names are
required. Please take a look at the
JavaRanch Naming Policy and
adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious. You may use initials for the first name but not the last.

You can change it here

The new server seems to require authentication (username/password), which the code is not supplying. Add that and see if it makes any difference.

Your name still does not match our naming policy. Please correct it ASAP.
