Sending mail using JavaMail APIs

In this example Google SMTP server is used to send email.

public class Email
{
    String  d_email = “your_id@gmail.com“,
    d_password = “your_password”,
    d_host = “smtp.gmail.com”,
    d_port  = “465″;
    public Email() { }
    public void sendEamil(String m_to , String m_subject , String m_text)
    {
        Properties props = new Properties();
        props.put(”mail.smtp.user”, d_email);
        props.put(”mail.smtp.host”, d_host);
        props.put(”mail.smtp.port”, d_port);
        props.put(”mail.smtp.starttls.enable”,”true”);
        props.put(”mail.smtp.auth”, “true”);
        //props.put(”mail.smtp.debug”, “true”);
        props.put(”mail.smtp.socketFactory.port”, d_port);
        props.put(”mail.smtp.socketFactory.class”, “javax.net.ssl.SSLSocketFactory”);
        props.put(”mail.smtp.socketFactory.fallback”, “false”);
        SecurityManager security = System.getSecurityManager();
        try
        {
            Authenticator auth = new SMTPAuthenticator();
            Session session = Session.getInstance(props, auth);
            session.setDebug(true);
            MimeMessage msg = new MimeMessage(session);
            msg.setText(m_text);
            msg.setSubject(m_subject);
            msg.setFrom(new InternetAddress(d_email));
            msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to));
            Transport.send(msg);
        }
        catch (Exception mex)
        {
            mex.printStackTrace();
        }
    }
    private class SMTPAuthenticator extends javax.mail.Authenticator
    {
        public PasswordAuthentication getPasswordAuthentication()
        {
            return new PasswordAuthentication(d_email, d_password);
        }
    }
}
