Javaメール認証を使用しているときに、Javaからの電子メールの送信に問題があります。次の例外が発生する方法がわかりません。

javax.mail.AuthenticationFailedException: 530 Access denied

コード全体を下に表示します。私が間違っていることを教えていただけますか？
認証を追加する前に、すべてが正常に機能したことに注意してください。また、2つの異なるドメイン（Gmailからyahooなど）間でメールを送信できるかどうか知っていますか？

これは、JSPアカデミックプロジェクトでGmailアカウントを介してメールを送信するために使用したコードです。

package my_util;

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

public class Mail
{
    private String  d_email = "myemailid@gmail.com",
                    d_password = "mypassword",
                    d_host = "smtp.gmail.com",
                    d_port  = "465";


    public boolean sendMail(String strTo, String strSubject, String strBody){

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

        try
        {
            Session session = Session.getDefaultInstance(props, null);
            MimeMessage msg = new MimeMessage(session);
            msg.setText(strBody);
            msg.setSubject(strSubject);
            msg.setFrom(new InternetAddress(d_email));
            msg.addRecipient(Message.RecipientType.TO, new InternetAddress(strTo));
            msg.saveChanges();

            Transport transport = session.getTransport("smtp");
            transport.connect(d_host, d_email, d_password);
            transport.sendMessage(msg, msg.getAllRecipients());
            transport.close();
            return true;
        }
        catch (Exception mex)
        {
            mex.printStackTrace();
            return false;
        }
    }

}

お役に立てば幸いです。:)
