Even running your own local resolver, if you generate enough traffic they'll still block you. I think their definition of open relay is based on traffic volume.

(which is their right, of course - just a warning that might help someone not find this out at 4am like I did)

Yes, because Spamhaus is a commercial enterprise. My own experience with their "free tier" limit is that it's generous and sufficient for personal use.

Oh sure, and their service is great and very much worth paying for.
