Email Safe Lists

Since the last update, I'm not receiving important emails nor can I send any to sites I've been a member of for years..Following the instructions to turn on the Safe List, , I would have to add at least 50 emails one....at....a ....time. If I add the one that I haven't received this week because it was blocked means I'll only receive that one email and no others. I don't have time to site here and add each of the 50 one at a time.  Plus some of the important emails don't have a strict address. It may come from a different person each time. Now what? 

Why do software updates always make things harder, not easier. I know they're looking out for their customers but....there has to be an easier way.
