Currently Missive keeps a list of email addresses which force a message to go to spam.

When we were trying to figure out why some messages were going to spam, it took a very long time to figure out it was missive.

We could stop messages from going to spam only when figured that out, and only by finding a message, marking it "not spam" and hoping that worked.

It would be nice if this "system rule" were visible, especially in the case where a user doesn't even realize they marked an email as spam.
