I have rented web hosting and some basic emails there were made. How do I transform then to catchall? Or maybe its not possible on all hostings? Anyway How I do that? Im asking because if I upload 100 emails straight to GSA its a big waste, because some emails will trigger errors (used already for a domain, so domain is skipped and lowers LPM), but changing every project ever,y day is painful too. So how to do catch all?
