Makes sense. But I’m not sure inverting is really what you’re doing. It seems to me that the people most effected by this will be people who actually want to reach you - Friends, family, work associates. They’ll have to jump through an extra hoop until they’re on your whitelist. On the other hand the spammers don’t really care if their message hits your particular inbox or not, as you’re just one of very many people they’re sending to. Still a cool solution though, and kudos to you for devising a system that works for you.
