Hi ALL,
I've looked thru the archive of this group regarding Javamail but could
not find answer to my problem:
I just want to send a message.
HERE IS MY CODE:

      String host = "...";
      int port = 2525;
      String from = "myname@myserver";
      String to = "other_name@gmail.com";

      // Get system properties
      Properties props = System.getProperties();

      // Setup mail server
      props.put("mail.smtp.auth", true);

      // Get session
      Session session = Session.getDefaultInstance(props, null);

      // Define message
      MimeMessage message = new MimeMessage(session);

      try
      {
          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 tr = session.getTransport("smtp");
          tr.connect(host, port, "mylogin", "mypsw");
          tr.sendMessage(message, message.getAllRecipients());
          tr.close();
      }
      catch (MessagingException e)
      {
          e.printStackTrace();
      }

AND HERE IS EXCEPTION THAT I GET:

javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
      com.sun.mail.smtp.SMTPAddressFailedException: 473
