It still gets the wrong answer for psd=n above psd=y.
Why?
See the example I posted last week.
(If the one beneath it has no DMARC record, is it still the org domain? I think
it is.)
This seems to be inconsistent with the sentence that follows. Would the
landscape change if .com suddenly publishes psd=y?
Currently with the PSL lookup, foo.com is an org domain whether or not it
publishes a DMARC record, and mail.foo.com and sales.foo.com are in
relaxed alignment. While I think it would be reasonable to say that an
org domain has to publish a DMARC record if it's going to be used for
relaxed alignment, that would be a change from the current rule.
Since there is no chance that .com .net .org or other large TLDs will ever
publish a PSD record it makes little difference in practice, but if we
agree the org domain needs a DMARC record, we should make clear that this
is a deliberate change. It's a good idea since if foo.com has no DMARC
record and .com has no PSD record, it won't work as an org domain anyway.
