I am getting this error on executing the email sending code using webtop 6.7

My ERROR:

javax.mail.SendFailedException: Sending failed;nested exception is:class javax.mail.MessagingException: 530 5.7.1 Client was not authenticated

MY CODE:

 

        Properties props = new Properties();
        //props.setProperty("mail.transport.protocol", "smtp");
        System.out.println(new DfTime().toString() +" - PRINT : "+ RexConstants.DOCBASE_NAME +" - EmailUtils : onInit() SendMessage :");
        props.setProperty("mail.host", RexConstants.SMTP_HOST);

        try {
            Session session = Session.getDefaultInstance(props, null);
            Message msg = new MimeMessage(session);
            //session.setDebug(debug);
            msg.setFrom(new InternetAddress(from));
            InternetAddress[] addressTo = new InternetAddress[recipients.length];
            for (int i = 0; i < recipients.length; i++) {
                addressTo[i] = new InternetAddress(recipients[i]);
                System.out.println(new DfTime().toString() +" - PRINT : "+ RexConstants.DOCBASE_NAME +" - EmailUtils : onInit() recipients : "+i+" "+recipients[i]);
            }
            msg.setRecipients(Message.RecipientType.BCC, addressTo);            

            // Set the subject of the email message
            msg.setSubject(subj);

            // Add the email message
            msg.setContent(body, "text/plain");
            msg.setDataHandler(new DataHandler(new ByteArrayDataSource(body, "text/plain")));

            if (pFlg)
                msg.setHeader("X-Priority", "1");

            Transport.send(msg);

What client is the error exaclty talking abt?

Is it a version mismatch error.I am moving the code from 5.3 to 6.7 CS and Webtop

Thanks in advance !!!

Your smtp-server tells you, that you need some kind of authentication before sending a mail, sometimes it might be just a valid sender-domain...
