As threatened, here's an I-D that says how one would publish a list of

Looks like a good start, and almost shockingly simple. Any MTA/MFA support
I still don't get why it's ok for John Levine to publish a list which
says that it's ok to discard unsigned mail from paypal.com, but st00pid
for paypal.com to publish the same thing. That is the essence of his
jihad against adsp.
Because presumably verifiers will trust John's process for compiling this
list more than they'd trust any random schmoe with the ability to create TXT
(If paypal were representative of all domains, this wouldn't be a concern.)
Well that's pretty ironic because paypal.com is listed in his database
as being discardable even after he got done telling them they were incompetent
for setting their ADSP record to discardable since they mix users and
mail all in the same sub domain. So it seems that John isn't any more competent
than paypal.com by his own competency test.
Personally, I think we'll need lists like this for a while in order to gain
more experience and determine best practices, and THEN we can decide whether
to change (or even scrap) ADSP to reflect those practices.
Who watches the watcher?
I'm very dubious that John can do that without explict bidirectional human
Which is no different than paypal.com publishing their ADSP record since
the people who put up the ADSP record are extremely likely to be the same people
telling John's list that they want to be set to discardable. What the value add
the middle man is here -- besides faithfully copying errors -- is a mystery.
NOTE WELL: This list operates according to
