Question

I am trying to send an email without SSL/TLS but receiving following exception:

javax.mail.MessagingException: Could not connect to SMTP host: mymail.test.com, port: 25;
 nested exception is:java.net.SocketException: Permission denied: connect
at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1282)

My code that send email : I have put System.setProperty("java.net.preferIPv4Stack" , "true") also as suggested in other posts and I m using java-6.

            String smtpHostServer = "mymail.test.com";
    String emailID = "user@test.com";
    System.setProperty("java.net.preferIPv4Stack" , "true");
    Properties props = System.getProperties();
    props.put("mail.smtp.host", smtpHostServer);
    props.put("mail.smtp.auth", "false");
    props.put("mail.smtp.starttls.enable", "false");

    Session session = Session.getDefaultInstance(props);
try {
        MimeMessage msg = new MimeMessage(session);
        // set message headers
        msg.addHeader("Content-type", "text/HTML; charset=UTF-8");
        msg.addHeader("format", "flowed");
        msg.addHeader("Content-Transfer-Encoding", "8bit");

        msg.setFrom(new InternetAddress("noreply@test.com",
                "NoReply-JD"));

        msg.setReplyTo(InternetAddress.parse("noreply@test.com",
                false));

        msg.setSubject(subject, "UTF-8");

        msg.setText(body, "UTF-8");

        msg.setSentDate(new Date());

        msg.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse(toEmail, false));
        System.out.println("Message is ready");
        Transport.send(msg);

        System.out.println("EMail Sent Successfully!!");
    } catch (Exception e) {
        e.printStackTrace();
    }
Was it helpful?

For above code just accept receiver and sender email id, password, subject and body part from user.
