Send an email over SSL + authentification(TLS)

Hi guys!

I need to send a mail in java.

I currently use javamail, with the user authentification, but without any SSL/TLS.

I need to do this very fast because I've a demo in a place where it's the only way to send an email.

So how can I do it?

//my current function
public void sendMessage(User usrto, String content, String subject) {
        try {
            Properties props = new Properties();
            props.put("mail.transport.protocol", "smtp");
            props.put("mail.smtp.host", SMTP_SERVER);
            props.put("mail.smtp.auth", "true");
 
            Authenticator auth = new SMTPAuthenticator();
            if (mailSession == null) {
                mailSession = Session.getDefaultInstance(props, auth);
 
                // uncomment for debugging infos to stdout
                //mailSession.setDebug(true);
            }
            Transport transport = mailSession.getTransport();
 
            MimeMessage message = new MimeMessage(mailSession);
            message.setContent(content, "text/plain");
            message.setSubject(subject);
            message.setFrom(new InternetAddress(EMAIL_FROM));
            message.addRecipient(Message.RecipientType.TO, new InternetAddress(usrto.getEmail()));
 
            transport.connect();
            transport.sendMessage(message, message.getRecipients(Message.RecipientType.TO));
            transport.close();
        } catch (Exception ex) {
            Logger.getLogger(EmailMessage.class.getName()).log(Level.SEVERE, null, ex);
        }
 
    }
