authorize.net email notification

www.govenom.com

the customer isnt recvng notification emails when someone pays. i checked the plugin and it's set for instant capture; but this option was set to no:

Allow payment notifications from %s for email notification does this need to be set to yes or no---it was set to " no ".

please advise..
thanks

That option needs to be turned on, otherwise, the payment notifications are not allowed and HikaShop won't confirm the orders automatically.
