    This is how email servers have worked for decades - there is no silver bullet and this comes closest. If you poorly admin your email instance, say allowing it to be an open relay (same as just allowing open registrations), you get blacklisted everywhere aka defederated. Same if you have a compromise and someone starts spamming out.
