for my store, I need to send copies of the orders to 2 different (administrative) people (besides the customer) after they are submitted... 1 to the order desk and 1 to the warehouse.
I'm pretty sure you will need to alter the code. Maybe you could sent the email to a dummy address like [email protected] and then forward to the 2 desired addresses.
Or, if your email host supports it, you can create a distribution group or MRA (multi recipient address) that goes to both email addresses. This is how have achieved this in the past.
