SendFailedException: 554 - Access denied ?!

Question

Hi people,
The following is a piece of code, my first try on JavaMail API....
public class SendMail {
public static void main(String[] args) {
try {
String host = "smtp.vsnl.com";
String from = "[email protected]";
String to = "[email protected]";
// Get system properties
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", host);
// Get session
Session session = Session.getDefaultInstance(props, null);
// Define message
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");
// Send message
System.out.println("Sending the message.......");
Transport.send(message);
System.out.println("Message sent..............");
}catch(Exception ex){
ex.printStackTrace();
The output -
Sending the message.......
Sending failed;
nested exception is:
javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
javax.mail.SendFailedException: 554 <[email protected]>: Sender address rejected: Access denied
The mail ids here are valid and infact I also tried some other non-yahoo / hotmail ids, but it still does not work !!!!!!!
Any fixes to be done to the code ??
Regards.

The SMTP server is setup to not relay messages for [email protected] This is generally done so someone cannot use the server to send spam out to the net. The server is probably setup to only relay messages for addresses and machines on its own domain. Try changing the from address to an address on the servers domain. It may not need to be a valid address although some machines are setup to check that too.
You can also try contacting the administrator of the server to see if there is anything he can/will do.
