This is the status quo. People may already be incorrectly unsubscribed. This is a real problem when it occurs. It can happen because a server refuses messages with illegal (RFC non-compliant) headers, as well as when the content is offensive.
Or when the server looks up your IP address and finds it on a black list, or thinks it finds it on a blacklist which no longer exists, or any number of other problems.
It doesn't matter. The point is that they're NOT saying the recipient doesn't exist. Currently, we treat this situation as if they do, and we shouldn't!
