We are using external billing system for our customers, and don't want that WHMCS is sending "new invoice" or "Reminder" -emails. I propably can disable reminders with some mysql oneliner because it exist in GUI also, but i can't disable "New Invoice" -email from anywhere.
So what i understand i need some hook to do that ?
Oh, and i still wan't that customers can have emails, like "Forgotten Password".
If this is trivial please give me an example and where to put that hook file, im not a developer, just old Linux admin 🙂
