It's been like that for a couple of years, don't think it's likely to
change.

Clarified that I'm referring to the section

I'm trying to keep all the operational stuff in the companion BCP.

How could anyone tell?  They pop up and disappear dailt.

Actually, the most common use of domain name DNSBLs is for the names
found in URLs in the bodies of spam, which doesn't need any
authentication.

Authentication only matters if you're whitelisting by sender, but I
don't know of anyone using DNSWLs for that.
