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

public class ForwardMail {

  public static void main(String args[]) throws Exception {
  String host = "192.168.10.205";
  String user = "test";
  String password = "test";

  // Get system properties
  Properties properties = System.getProperties();
  properties.setProperty("mail.smtp.host", "192.168.10.205");

  // Get the default Session object.
  Session session = Session.getDefaultInstance(properties);

  // Get a Store object that implements the specified protocol.
  Store store = session.getStore("pop3");

  //Connect to the current host using the specified username and password.
  store.connect(host, user, password);

  //Create a Folder object corresponding to the given name.
  Folder folder = store.getFolder("inbox");

  // Open the Folder.
  folder.open(Folder.READ_ONLY);

  Message message = folder.getMessage(1);

  // Here's the big change...
  String from = InternetAddress.toString(message.getFrom());
  if (from != null) {
  System.out.println("From: " + from);
  }
  String replyTo = InternetAddress.toString(
  message.getReplyTo());
  if (replyTo != null) {
  System.out.println("Reply-to: " + replyTo);
  }
  String to = InternetAddress.toString(
  message.getRecipients(Message.RecipientType.TO));
  if (to != null) {
  System.out.println("To: " + to);
  }

  String subject = message.getSubject();
  if (subject != null) {
  System.out.println("Subject: " + subject);
  }
  Date sent = message.getSentDate();
  if (sent != null) {
  System.out.println("Sent: " + sent);
  }
  System.out.println(message.getContent());

  // Create the message to forward
  Message forward = new MimeMessage(session);

  // Fill in header
  forward.setSubject("Fwd: " + message.getSubject());
  forward.setFrom(new InternetAddress(from));
  forward.addRecipient(Message.RecipientType.TO,
  new InternetAddress(to));

  // Create your new message part
  BodyPart messageBodyPart = new MimeBodyPart();
  messageBodyPart.setText("Oiginal message:\n\n");

  // Create a multi-part to combine the parts
  Multipart multipart = new MimeMultipart();
  multipart.addBodyPart(messageBodyPart);

  // Create and fill part for the forwarded content
  messageBodyPart = new MimeBodyPart();
  messageBodyPart.setDataHandler(message.getDataHandler());

  // Add part to multi part
  multipart.addBodyPart(messageBodyPart);

  // Associate multi-part with message
  forward.setContent(multipart);

  // Send message
  Transport.send(forward);

  System.out.println("msg forward ....");
  }
}
