Outlook delete attachment files if use POP3

Question

Hi every body,
I have a problem with outlook. I send a mail with attachment using java mail api. Anyone get the mail correctly (gmail, outlook, outlook express or thunderbird) via SMTP. But if outlook try to get the mail via POP3, it deletes attachment and show only other part of mail. Other clients dont do it include outlook express. I dont have any idea about this situation. Can any body help me?
My mail code is here:
Properties props = new Properties();
props.put("mail.smtp.host", server);
props.put("mail.smtp.port", String.valueOf(port));
session = Session.getDefaultInstance(props, null);
transport = session.getTransport("smtp");
     MimeMessage msg = new MimeMessage(session);
     msg.setSentDate(new Date());
     msg.setFrom(fromAddress);
     msg.setRecipients(Message.RecipientType.TO, toAddress);
     msg.setSubject(subject, "UTF-8");
     MimeBodyPart messageBodyPart = new MimeBodyPart();
     String htmlEncoded = TurkishLocaleHelper
               .convertTrToUTF8(message);
     messageBodyPart.setText(htmlEncoded);
     messageBodyPart.setHeader("Content-Type",
               "text/html;charset=UTF-8");
     messageBodyPart.setHeader("Content-Transfer-Encoding",
               "quoted-printable");
     MimeMultipart multipart = new MimeMultipart(
               "alternative");
     multipart.addBodyPart(messageBodyPart);
     if (mailItem.getAttachmentFileList() != null) {
          for (String fileName : mailItem.getAttachmentFileList()) {
               BodyPart fileBodyPart = new MimeBodyPart();
               DataSource source = new FileDataSource(fileName);
               fileBodyPart.setDataHandler(new DataHandler(source));
               fileBodyPart.setFileName(FileUtil.trimFilePath(fileName));
               multipart.addBodyPart(fileBodyPart);
     if (mailItem.getAttachmentFileMap() != null) {
          Map<String, String> fileMap = mailItem.getAttachmentFileMap();
          Set<String> keySet = fileMap.keySet();
          for (String filePath : keySet) {
               String fileName = fileMap.get(filePath);
               BodyPart fileBodyPart = new MimeBodyPart();
               DataSource source = new FileDataSource(filePath);
               fileBodyPart.setDataHandler(new DataHandler(source));
               fileBodyPart.setFileName(fileName);
               multipart.addBodyPart(fileBodyPart);
     msg.setContent(multipart);
     msg.saveChanges();
transport.sendMessage(msg, msg.getAllRecipients());Edited by: vistek on Apr 13, 2010 6:10 AM

Yes i was wrong. I use SMTP to sent mail, and POP3 to read it. Mail is shown with attachment in gmail but it is shown only body in outlook. If i open socket and sent mail via socket it is worked.
Now i search using this method with attachment. Does any body know that?
Example code:
import java.net.*;
import java.io.*;
public class SMTP {
  private String message;
  private String localMachine;
  private String senderName;
  private String recipient;
  private boolean valid_and_unsent = false;
  private BufferedReader in;
  private BufferedWriter out;
  // class constants
  public static final int SMTP_PORT = 25;
  private static final boolean logging = true;
  public SMTP() {
  public SMTP(String sender) {
    int indexOfAtSign = sender.indexOf('@');
    if (indexOfAtSign < 0) {
      throw new RuntimeException("Malformed sender address." +
        " Need full user@host format");
    this.senderName = sender.substring(0, indexOfAtSign);
    this.localMachine = sender.substring(indexOfAtSign + 1);
  public SMTP(String sender, String recipient, String message) {
    this(sender);
    setMessage(recipient, message);
  public void setMessage(String recipient, String message) {
    this.recipient = recipient;
    this.message = message;
    valid_and_unsent = true;
  public void send() throws IOException {
    if (!valid_and_unsent) {
      throw new RuntimeException("Attempt to send incomplete message," +
        " or send message twice");
    // if this message is legitimate, continue to extract
    // the remote machine name
    int indexOfAtSign = recipient.indexOf('@');
    if (indexOfAtSign < 0) {
      throw new RuntimeException("Malformed recipient address." +
        " Need full user@host format");
    String destinationMachine = recipient.substring(indexOfAtSign + 1);
    // attempt to make the connection, this might throw an exception
    Socket s = new Socket(destinationMachine, SMTP_PORT);
    in = new BufferedReader(
           new InputStreamReader(s.getInputStream(),"8859_1"));
    out = new BufferedWriter(
           new OutputStreamWriter(s.getOutputStream(),"8859_1"));
    String response;
    // discard signon message, introduce ourselves, and discard reply
    response = hear();
    say("HELO " + localMachine + "\n");
    response = hear();
    say("MAIL FROM: " + senderName + "\n");
    response = hear();
    say("RCPT TO: " + recipient + "\n");
    response = hear();
    say("DATA\n");
    response = hear();
    say(message + "\n.\n");
    response = hear();
    say("QUIT\n");
    // now close down the connection..
    s.close();
  private void say(String toSay) throws IOException {
    out.write(toSay);
    out.flush();
    if (logging) {
      System.out.println(toSay);
  private String hear() throws IOException {
    String inString = in.readLine();
    if ("23".indexOf(inString.charAt(0)) < 0) {
      throw new IOException("SMTP problem: " + inString);
    if (logging) {
      System.out.println(inString);
    return inString;
  public static void main(String args[]) throws Exception {
    BufferedReader in = new BufferedReader(
                               new InputStreamReader(System.in));
    System.out.print("Your address: ");
    System.out.flush();
    String sender = in.readLine();
    System.out.print("Recipient address: ");
    System.out.flush();
    String recipient = in.readLine();
    String message = "";
    String part;
    System.out.println("Message, end with '.' by itself:");
    for (;;) {
      part = in.readLine();
      if ((part == null) || part.equals(".")) {
        break;
      message += part + "\n";
    SMTP mailer = new SMTP(sender, recipient, message);
    mailer.send();
