Aha.  Maybe you could add something like this after the "## End Gnus
Sieve Script" marker:

fileinto "INBOX.spam";

I guess I was thinking of adding a always-matching rule on your spam
group

if header :contains "Received" "" {
	fileinto "INBOX.spam";
}

and making sure it was last in the file (which unfortunately isn't
possible right now, I think).
