In article <CAHej_8kpT2ooFoJdsj1X+AV90HEA29yABJVp+EhrpJNXxWpnOA@mail.gmail.com> you write:
>Is it not also important to note that the recipient of the failure report

The exact same issue applies to aggregate reports which can leak a
fair amount of PII from domains with modest amounts of traffic so you
can guess who sent what.  See my prior message about the county government.
