The ISP can consent, but what about the users of the ISP? In most
cases the users have no knowledge of the fact that a blacklist is
even in use.
That depends on the ISP. We provide our users with the ability to control
how or if their mail is blocked/filtered.
Their widespread use indicates that many receivers of
email have confidence in at least some DNSBLs.
Very few end users know that blacklists are in use.
Again, that depends on the ISP. DNSbls can be a very effective tool,
especially when users are aware of their availability and have control
over their use.
Thirdly, in the "BEST PRACTICES" section, you talk about creating some
sort of "common agreement on best practices for blacklists setting out
criteria for issues such as notice to the listed parties, appeals
processes and the acceptability of `collateral damage'." This is both
unnecessary and undesirable.
It is unnecessarey because DNSBLs can not force anyone to do anything,
their only authority comes from others who freely choose to use them.
Again, this is a very sysop centric view of the world. I do not believe
that system or network operators are the ultimate arbiters of the
Internet.
ISPs can and should decide how best to run their own mail servers with
the customer's best interest in mind. If that includes use of DNSbls,
then so be it.
The 'right' that appears to be being defended here is the right of
sysops to make decisions on behalf of their users with no
accountability.
Nobody said anything about "no accountability." I sense here nothing more
than a strong hatred of DNSbls, likely due to a bad experience with them.
