This strikes me as unrelated to DNSBLs. Am I misunderstanding?
How is this DNSBL-specific?
Al, and others,
While many of us are less opposed to DNSBLs in principle
You misunderstand. Let's take a step back.
(1) If the system supporting the DNSBL is following the email
protocols and decides to reject the message or bounce it, rather
than, e.g., assigning a score and moving it into the
user-related mail store, it replies back to the IETF list
manager, not the original sender.
Let's reword that a bit.

protocols and decides to reject the message or bounce it, rather
than, e.g., assigning a score and moving it into the
user-related mail store, it replies back to the IETF list

Again, how is this DNSBL-specific?
I'm not trying to fight about whether or not DNSBLs are awesome. I'm
asking clarification for your point, which I'm not understanding. I'm
seeing, for example, a statement that says "DNSBLs do X" when it seems
to actually say "non-delivery of mail actually works like *this*", and
I am unable to see the connection to DNSBLs.
Apologies for not being clearer.
Regards,
Al Iverson
