Apologies for the top-posting, but this is exactly the scenario that has been discussed earlier on the list: https://www.ietf.org/mail-archive/web/dmarc/current/msg04151.html as well as during the recent IETF101 meeting: https://datatracker.ietf.org/doc/minutes-101-dmarc/
The problem really is (at the moment) that there is no basis in the lookup algorithm to ever query the "last public" domain (aka "org-1"). Would the community be open to adding a third potential lookup to the algorithm? 1 - check the domain itself 2 - check the org domain 3 - check org-1 --Kurt On Wed, Apr 4, 2018 at 9:52 AM, Paul Rock <paul.r...@teamaol.com> wrote: > Considering that the qld.gov..au <http://qld.gov.au> record includes an > sp tag, I'd say that they intend and expect that the TLD entry does exactly > that - puts DMARC reporting in place for all subdomains that don't have > their own record. > > On Tue, Apr 3, 2018 at 3:02 PM, Tomki Camp <tki=40tomki....@dmarc.ietf.org > <tki=40tomki....@dmarc.ietf..org>> wrote: > >> Currently defined policy discovery https://tools.ietf.org/html/rf >> c7489#section-6.6.3 >> >> This begs the question (for which a real example now exists): what if a >> listed suffix (TLD?) itself has a DMARC record?
