I don't. I didn't see that header. The original set of quoted headers had an authenticated submission header so that RDNS_NONE had a different cause, that rule wont be triggered on a trusted identifiable submission server. You do need to be sure that your internal network is correctly configured (or autoguessed) for ordinary mail delivery. If it isn't you'll be missing a lot of useful look-ups. If your ISP feels it doesn't need to record rDNS, it's unlikely to change it just for you. You'd be better of scoring RDNS_NONE at 0, and using the BOTNET plugin which does its own rDNS lookups. The plugin also does a full circle DNS check.
