Rather than calling a solitary policy flag "I sign everything", this
flag would be better described as "I am being phished". The use of this
flag will come to represent a dire situation as it will also likely
induce a myriad of delivery issues. As such, this policy might be
published by only a small portion of the overall domains.
A rare policy will expend greater efforts searching each 2822.From for
policies up name trees that in the end are unlikely to exist. Even if
DKIM were being used, the suitable default is implied when nothing is
published. A repository listing phished domains would likely gain
greater adoption and consistent use by DKIM verifiers. This repository
could identify those being phished as well as their look-alikes.
