Authorize.net Email Receipt

[FredJones]

Says in http://wiki.civicrm.org/confluence/display/CRMDOC/Authorize.net+Configuration :

Email Receipt: If this is set, Authorize.Net will send an email when a payment is processed. If Send Email is also selected in the CiviCRM Authorize.Net Payment Processor settings, two emails will be sent per payment.

I see no way to set this on my page /civicrm/admin/paymentProcessor?action=update&id=1&reset=1 yet the email IS going out from Authorize.net and they say it's b/c CiviCRM is requesting it to go out.

How can I disable this so that NO email goes out from Authorize.net?

I can't be 100% sure on the CiviCRM end of the configuration. But there is a setting over on the Authorize.net site that says

Enable Email Confirmation
   Email transaction receipt to customer (if email address is provided)

It is on the Account / Settings page under
Transaction Format Settings /   Transaction Response Settings /  Email Receipt(Link)
