I am using Magento Enterprise 188.8.131.52.
After creating two client account to run tests, I placed two order, one for each client. An order confirmation for the first order is sent to both client 61 times per hour since then. I tried removing all mention of the sending sales@ email address from the configuration panel and disabling email sending from config. Both the server and the template support indicate that it stems from a bug in Magento.
How can I : 1. Stop the flow of email 2. Ensure proper functioning of automated order confirmation sending
