Authorize.net SIM Confirm Email Sent Prior to Payment Entry

I am running opencart 1.4.9 and am using Qphoria's Authorize.net SIM payment module. The order confirmation emails are sent out when the customer presses "Confirm Order" which is prior to their credit card actually being processed. Is there a solution for this? Obviously an order isn't final until someone pays.

Any help is appreciated.

Thank you,
Susan

I would also like to know more about the email notifications. It seems logical that any order or payment confirmation should not be sent until after the payment is complete.
