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.
