Marketpress Confirmation emails are not sending.


I've installed marketpress and sucessfully setup products and my payment gateway; but it appears that confirmation emails are not being sent out when new orders are placed-- not to the order recipient, nor to as is set in the Messages tab of Marketpress' settings page.

I've confirmed that php_mail() is fuctioning correctly on my host, and also that the WordPress native password reset function is working properly.

Please Help??
