I have recently configured new order notification email for two different email ids but i received order notification on only first email but not receiving on second email or more and i am using default magento sender email `sales@example.com` and magento version is `1.9.0.1`. I have also tried using comma like `demo@gmail.com,demo1@gmail.com` but it is not working.
So please let me know how i configured it.

Thanks
