When moving a Quotation --> Save --> Confirm --> Create and View Invoice --> Post: 2 emails get sent to the Invoice address for a Customer.

Ideally it wouldn't send emails until I push Send by Email or Send and Print, or at least it sent single emails to the Main Contact and the Invoice emails.

Can anyone point me to the right direction where I can change this behavior? UI would be best as it's an ordeal to get my IT department to allow me to ssh into my server from VPN.
