I just posted this over on comp.mail.sendmail, but the gist of it is:
Sometimes spamhaus hands off a query to their dnsbls of 127.255.255.255 or 127.255.255.254, indicating that you're being rate limited.
This is bad, as when you get that, you start rejecting mail. I recently discovered this on my personal system as my OS's built in resolver was silently forwarding to 1.1.1.1/8.8.8.8. Obviously I've already fixed the DNS problem, but I'd like to prevent this in the future.
It looks like the version of enhdnsbl.m4 simply checks for *any* return code and doesn't know how to skip those responses. And I don't know where to buy the brand of LSD that they did at UC Berkeley when they wrote this, in order to make m4 make sense.
