Below is the source code of the program.

package com.test.test;

import java.security.Security;
import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.NoSuchProviderException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class JavaMailApp {
	
	
	public static void main( String[] args )
    {	

		String d_email = "[e-mail]";
		String d_uname = "ots.support";
		String d_password = "password";
		String d_host = "mail.test.com";
		String d_port  = "465"; //465,587
		String m_to = "[e-mail]";
		String m_subject = "Testing";
		String m_text = "Hey, this is the testing email.";
		
		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.debug", "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");
		
		SMTPAuthenticator auth = new SMTPAuthenticator();
		Session session = Session.getInstance(props, auth);
		session.setDebug(true);
		
		MimeMessage msg = new MimeMessage(session);
		try {
			msg.setText(m_text);
			msg.setSubject(m_subject);
			msg.setFrom(new InternetAddress(d_email));
			msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to));
			
			Transport transport = session.getTransport("smtps");
			transport.connect(d_host, 465, d_uname, d_password);
			transport.sendMessage(msg, msg.getAllRecipients());
			transport.close();
		} catch (MessagingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

    }
}

public class SMTPAuthenticator extends Authenticator{
	public PasswordAuthentication getPasswordAuthentication()
    {
        return new PasswordAuthentication("[e-mail]", "password");
    }
}

I have also added the certificate to my keystore using the following command and still i am facing this issue.

keytool -import -trustcacerts -alias root -file mail_test_com.crt -keystore keystore.jks
