The score was pretty much informational only previously and arbitrarily
set. The current score is what the mass-checks and GA result in.

I guess you need to correct your trusted and internal networks. The rule
does not deep parse, and never has.

  header __RDNS_NONE  X-Spam-Relays-Untrusted =~ /^[^\]]+ rdns= /
  describe RDNS_NONE  Delivered to trusted network by a host with no rDNS

That host with an IP in a private, reserved range (the originating IP,
running the MUA?) delivered directly to your MX, as it seems...
