    Hi I have a question about Feedback Loops (FBL), I tried searching and got confused. For example, this is a site on SMTP and it says: "The Feedback Loop notifies you which of your messages were 'marked as spam' by which recipients. Based on this information, you can modify your email list and messages accordingly," but the page doesn't explain further. So I wonder, are feedback loops something that can be implemented using SMTP? Are they automatic? How do they work?

    Thank you in advance!
