Having gone to a lot of MAAWG meetings, and talked to people who run
the mail systems at every large ISP in the country, and quite a few in
other countries, I can report that their experience with DNSBLs is
utterly unlike yours.  There are plenty of incompetently run DNSBLs,
but nobody uses them so they don't matter.

In that initial order which as based efficiency and turn around time. The algorithm monitors changes the order based on response rates. Higher overhead lookups moves the site to the bottom, better responses move it to the top of the query test.

I have my reservations about the wisdom or utility of providing fine
grained reports to people whose mail you don't accept, but not because
of error rates in DNSBLs.
