Please help me to figure out.

Actually mail server is not supporting cross domain mail sending.
With in the same domain it is working.
But in spite of having a solution i still have a lot of problems .....

[code=java]
Properties props = new Properties();
props.put("mail .smtp.host", "iem.iitkgp.ern et.in");
props.put("mail .debug",true);

Session session = Session.getInst ance(props,new Authenticator() {
protected PasswordAuthent ication getPasswordAuth entication(){
return new PasswordAuthent ication("erp@ie m.iitkgp.ernet. in","erp2008" );
}
});
session.setDebu g(true);

Message msg = new MimeMessage(ses sion);
msg.setFrom(new InternetAddress ("erp@iem.iitkg p.ernet.in"));
InternetAddress[] address = {new InternetAddress ("debasis.jana. iit@gmail.com") };
msg.setRecipien ts(Message.Reci pientType.TO, address);
msg.setSubject( "JavaMail APIs Test");
msg.setSentDate (new Date());
msg.setText("Th is is a message body.\nHere's the second line.");

Transport.send( msg);
[/code]

This is my source code.
If i change the from address to wrong address and even it is from cross domain then still it's working.
Anyway I think need to go through the details of SMTP server.
I think then i can figure out myself what's wrong with it.
I need all of your best wishes.
