3.6 The scope of the listing MUST be disclosed
Some DNSBLs have adopted a policy of listing a range of IP addresses under
the control of a provider even though some of those IP addresses are not the
source of abusive email.
Spot the hidden assumptions.
They aren't true.
The theory is that customers impacted by such a
listing will apply pressure on the provider to take action against
the customer
which is the source of the abusive email.
Whose theory is that?
Such a DNSBL policy is highly
controversial, and discussion of its appropriateness is beyond the scope of
this document.
So why bring it up in the first place?
A DNSBL MUST specify the scope of the listing and disclose whether
it may include
an IP address which has not been identified as the source of abusive email.
How is that not part of the listing criteria in the first place?
"This DNSBL lists all IP addresses if the number of spam-emitting IPs
in their /24 exceeds 10." To anybody who can read, that discloses
whether it may include an IP address that didn't emit spam.
