I think I agree with you here. I was just trying to give an example
why BigBank would like to publish ADSP records that cause MTA
operators to treat mails from
info(_at_)mail(_dot_)account(_dot_)bigbank(_dot_)com as
"suspicious" (or something).
Oh, I have no doubt that bigbank.com would like to blanket the DNS with
discardable ADSP records. The question is whether any receivers would
care. I wouldn't, since I don't consider a.b.foo.com any more similar to
foo.com than a-b-foo.com.
Among the many conceptual problems that plague ADSP is the fantasy among
some senders that this will somehow give them more control over what
receivers do with their mail.
