I can answer this one :)  $Junk and $NotJunk are designed to be set by the client in order to provide feedback to the server in order for it to update its engine (i.e. by feeding into a Bayes database). $Phishing is designed for the server to add an "I delivered this to your mailbox but since then I've learned that it's bad" - it's never set by clients.

This information is a direct copy of what's in the IANA registry already:
