[dns-operations] Survey on DNS resolver operations and DNSSEC

I’m checking internally what ours does, but it’s not a “simple” binary question.
We did have it turned on in the past, but doing so meant we couldn’t get email from several organisations we work with as their DNSSEC setup was broken. And of course it took time to realise that we weren’t getting those emails.

Regards

Michele

Is that (economic) argument all there is to it? -- If so, wouldn't one expect all resolver operators to do DNSSEC validation? (Validation prevalence is far from 100%.)

Best,
