Hey Thanks a lots to @Rich Peck and @Mandeep for there efforts. I have solved the issue now.. by putting more effort on searching. I have just added one line and it works..

config.action_mailer.smtp_settings = {
      address: 'smtp.gmail.com',
      port: 587,
      domain: 'gmail.com',
      user_name: 'mygmail_id@gmail.com',
      password: 'mygmail_password',
      authentication: 'plain',
      enable_starttls_auto: true,
      :openssl_verify_mode => 'none'  # This line added and it works fine
}
