Forum Disabling only automated e-mails in test forum
 

I know how to disable all e-mail functions on my test forum, but what I want to do for testing purposes is allow manual e-mails. What I don't want is any automated e-mails, like subscriptions or weekly summaries, etc.
Would I have to go to each scheduled task and turn them all off or is there a setting to allow a global disable for all automated e-mails?

Thanks for any help or advice with this.
