That isn't a helpful metric. The 99% most likely domains to

and they pass. So if you're only checking domains without
DKIM signatures (broken or otherwise), you're going to get
a self fulfilling prophecy.
A much better test would be compile a list of DKIM signing
domains, and do the ADSP query on them.
Yeah, that's what I meant when I referred to doing five figures worth of TXT
queries.
I think it would be worth it, since the numbers are almost
certainly going to be better, even if they're not great. There's
nothing worse than a stat-as-meme that originate from highly
flawed studies.
