That's a payment notification email which can't be turned off when using E-junkie.

BTW, this doesn't involve anything sent from Authorize.net, but if you want to disable the transaction notification that E-junkie sends to your buyers, you can do this on a per-product basis (unfortunately, there is no blanket way to disable E-junkie buyer notification across the board all at once). In Seller Admin, for each product you don't want to have sending an E-junkie email:



* Edit that product (or Add a new one);

* On the Product Configuration screen, checkmark Enable Templated Email;

* Leave the Email Subject and Email Message boxes blank (it cannot send templated email if there is no subject nor template to send!).

Why can the authorize.net email feature not be turned off? Why would e-junkie automatically override this control without giving users the option to control this? It really defeats the point in Authorize.net providing that option to users in the first place.

I spoke to our Lead Developer, and he says he'll have a solution devised for you within a few days. You'll know more as soon as we do. :^)
