Years ago I would turn off X-Originating-IP, but now I keep it turned on because It is necessary for the IP blocking capability of DoSFilter, which I find very useful. The false positives in my experience are all from ZCO users on dynamic and other IP addresses that SpamAssassin wants to block/score...
