import java.util.Properties;

import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
public class SendMailExchange {
     public boolean sendMail() {
          try {
               String from = "email";
               String to = "email";
               String host = "servername";
               String username = "sumant_chhunchha";
               String password = "password";
               Properties p = System.getProperties();
               //p.put("mail.smtp.host", host);
               p.put("mail.transport.protocol", "smtp");
               p.put("mail.smtp.port", "25");
               p.put("mail.smtp.auth", "true");
          //     p.put("mail.smtp.allow8bitmime", "true");
          //     p.put("mail.smtp.auth.mechanisms", "GSSAPI NTLM");
          //     p.put("mail.smtp.starttls.enable","true");
          //     p.put("mail.smtp.starttls.required","true");
                    Authenticator auth = new SMTPAuthenticator(username, password);
               Session session = Session.getInstance(p, auth);
               // Session session = Session.getInstance(p);
               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();
               // Send message
               Transport transport = session.getTransport("smtp");
               transport.connect(host, username, password);
               transport.sendMessage(message, message.getAllRecipients());
               transport.close();
               // Transport.send(message);
          } catch (Exception e) {
               e.printStackTrace();
               return false;
          return true;
     public static void main(String args[]) {
          new SendMailExchange().sendMail();
     class SMTPAuthenticator extends Authenticator {
          String username;
          String password;
          public SMTPAuthenticator(String username, String password) {
               super();
               this.username = username;
               this.password = password;
          public PasswordAuthentication getPasswordAuthentication(
                    String username, String password) {
               return new PasswordAuthentication(username, password);
}I have just kept commented code to show what else I have tried.
