Finding SMTP mail server

[rajujrk]

hi, i am currently sending mail through the JavaMail API. I had a problem to find out the SMTP mailserver. First i tried in airtel broadband Connection its works fine..
but now i using it in my college lab. we have broadband internet connection, but dont know what kindof connection..
Here is my Code

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

class SendMail{
  public static void main(String[] jrk)throws Exception{
  String email="tomail@gmail.com";
  Properties props = new Properties();
  props.put("mail.smtp.host", "smtp.tn.airtelbroadband.in");
  
  Session s = Session.getInstance(props, null);
  MimeMessage message = new MimeMessage(s);
  InternetAddress from = new InternetAddress("frommail@gmail.com");
  message.setFrom(from);
  
  InternetAddress to = new InternetAddress(email);
  message.addRecipient(Message.RecipientType.TO, to);
  message.setSubject("Login Information");
  message.setText("Thank you for logged in..");
  Transport.send(message);
 }
}

How to find out the SMTP mail server..
This is a stand alone program, used in any machine..

Thanks in Advance..

You should probably ask your professor/instructor about the mail server name, it should work. Also, if you're not supposed to know it, you cannot connect to it.

Hope this helps direct you!
