Answer 1

(Assuming I understand your goal and it's not to send spam) The Apache Commons library we use does it by calling setPersonal on the InternetAddress. http://docs.oracle.com/javaee/7/api/javax/mail/internet/InternetAddress.html#setPersonal-java.lang.String-java.lang.String-

        Message message = new MimeMessage(session);
        InternetAddress me = new InternetAddress("from-email@gmail.com");
        me.setPersonal("My name");
        message.setFrom(me);

Here is the full code You can use the following code. This is working Fine for me

class SendMail {
public static void main(String[] args) {
    System.out.println("In side main()---------------------");

    Properties props = new Properties();


    props.put("mail.smtp.host", "hostname");
    props.put("mail.smtp.port", "port");//

    props.put("mail.smtp.socketFactory.port", "port");
    props.put("mail.smtp.socketFactory.class",
            "javax.net.ssl.SSLSocketFactory");



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

    Session session = Session.getDefaultInstance(props,
            new javax.mail.Authenticator() {

                protected PasswordAuthentication getPasswordAuthentication() {
                    System.out
                            .println("In side getPasswordAuthentication------------------And Before returning PasswordAuthentication");
                    return new PasswordAuthentication("from@gmail.com",
                            "password");

                }

            });
    System.out
            .println("mail and password has been sent********************");
    try {
        System.out
                .println("we are  in try{} block.................................");
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("from@gmail.com"));
        message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("to@gmail.com"));
        message.setSubject("Testing Subject");
        message.setText("Dear User," + "\n\n This is testing only!");

        Transport.send(message);

        System.out
                .println("Mail has been sent successfully..........................");

    } catch (MessagingException e) {
        System.out.println("we are in catch block...................");
        e.printStackTrace();

    }
}

}

Many reputable SMTP relays will not allow you to fake your identity (that would make it even easier for spammers to abuse the service). That said, if your goal is to avoid more mail in your inbox, Google allows you to modify your email address so that you could filter any replies to your email.

Faced Same problem while using "smtp.gmail.com". Use Mandrill,it will work. Once you setup a Mandrill account,use "smtp.mandrillapp.com" on port 587. For Authentication,set username=your mandrill username and password=API key generated in your account.
