Re: [ietf-dkim] protecting domains that don't exist

 DNS administrators ...
But they are, as far as this protocol is concerned, our customers.

No, they're not.  They one of many suppliers to our customers.  Our 
customers are people who send and recieve mail.

The requirement to publish large numbers of ADSP records is a barrier to its 
widespread adoption, at least its adoption in a way that provides broad 
coverage for domains.  This can be addressed with tools, but the requirement 
to add tooling to achieve good ADSP coverage is also a deployment barrier.

Perhaps, although as I've said, reducing the work for DNS toolsmniths from 
N changes to N-1 changes doesn't strike me as as a very good rationale for 
a long term gross hack.  If the history of SPF is any guide, should we 
ship ADSP with this hack, people will start claiming that all domains must 
change their naming conventions so they're only two levels deep.
