I'm having some difficulty determining how (if possible) to email a customer's order and packing slip to a second party (warehouse) for shipping after an order has successfully been placed, as I don't stock/ship my own products.

Would this be something as simple as specifying a second email address under the email options/order confirmation setting, or would I need to install/modify a custom module? All I want to do is email the order/packing slip to another party (warehouse), after an order has been placed.

Thanks in advance.
