如何使用微软交换服务器使用javamail 1.5.1发送邮件？

Question

I've passed my day to search how sending mail with javamail 1.5.1 using microsoft exchange server and i didn't found a solution for my project.

  public static void sendMail(String message_dest,String message_objet,String message_corps){

  Authenticator auth;
  Session session;
  Message mesg;

  Properties props = new Properties();

  props.put("mail.transport.protocol", "smtp");
  props.put("mail.smtp.port", "25");
  props.put("mail.smtp.host", "10.X.X.X");
  props.put("mail.smtp.auth", "true");

  //Authenticator auth = new MyAuthentificator();
  auth = new javax.mail.Authenticator() {
     protected PasswordAuthentication getPasswordAuthentication() {

        return new PasswordAuthentication(
           "xx@xx.com", "xx");
     }
  };

  session = Session.getDefaultInstance(props, auth);

  session.setDebug(true);

  try {
     mesg = new MimeMessage(session);

     mesg.setFrom(new InternetAddress(xx@xx.com));

     InternetAddress toAddress = new InternetAddress(message_dest);
     mesg.addRecipient(Message.RecipientType.TO, toAddress);

     mesg.setSubject(message_objet);

     mesg.setText(message_corps);

     Transport.send(mesg);

  } catch (MessagingException ex) {
     while ((ex = (MessagingException)ex.getNextException()) != null) {
        ex.printStackTrace();
     }
  }
}

I've already try to move out my authentification in an other class but it won't work too...

Please help :(

PS: Sorry for my english...

There is no authentification in your option talib2608 :( But I looked at these links and now my authentication works fine. (thanks bill shannon)

   public static void sendMail(String message_dest,String message_objet,String message_corps){

  Authenticator auth;
  Session session;
  Message mesg;

  Properties props = new Properties();

  props.put("mail.transport.protocol", "smtp");
  props.put("mail.smtp.port", SMTP_PORT1);
  props.put("mail.smtp.host", SMTP_HOST1);
  props.put("mail.smtp.auth", "true");
  props.put("mail.smtp.ssl.enable", "true");

  session = Session.getInstance(props);

  session.setDebug(true); 

  try {
     mesg = new MimeMessage(session);

     mesg.setFrom(new InternetAddress(IMAP_ACCOUNT1));

     InternetAddress toAddress = new InternetAddress(message_dest);
     mesg.addRecipient(Message.RecipientType.TO, toAddress);

     mesg.setSubject(message_objet);

     mesg.setText(message_corps);

     Transport t = session.getTransport("smtp");
     try {
         t.connect("xx@xx.com", "mypwd");
         t.sendMessage(mesg, mesg.getAllRecipients());
     } finally {
         t.close();
     }

  }catch (MessagingException ex){
     System.out.println(ex);
  }
}

But when I try it, i don't receive my message...

DEBUG: setDebug: JavaMail version 1.5.2
DEBUG: getProvider() returning javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Oracle]
DEBUG SMTP: useEhlo true, useAuth true
DEBUG SMTP: trying to connect to host "xx.xx.xxx.xx", port 25, isSSL true
javax.mail.MessagingException: Could not connect to SMTP host: xx.xx.xxx.xx, port: 25;
  nested exception is:
    java.net.SocketException: Connection reset

This error message comes when i test on my local machine, not on the server.
