I did not see a definition of a “non-existent domain” (the np policy). A definition is needed.
To my thinking, the obvious rule should be to query for a NS record for the domain. If the record exists, then the domain owner could create a DMARC record for that domain, or could create a default entry for the domain at the organizational level. If no record exists, it is because the domain owner chose to not create one. However, the DMARC Bis document conflicts strongly with this. In section A.4, it suggest several ways to do a test of this type, then repudiates all of them. NS lookup is not one of the mentioned options. There is a possible second-level policy test for a “mail-enabled domain”. I would define that test as “MX record exists or SPF policy exists”. That could be an additional option to NP, but should not be a replacement for it. PSD for DMARC clearly intends for the NP policy to be a general solution to a general problem. If there are still objections to it becoming a general solution, this should be addressed soon. Doug Foster From: dmarc [mailto:dmarc-boun...@ietf.org] On Behalf Of Tim Wicinski Sent: Friday, November 13, 2020 1:42 PM To: IETF DMARC WG Cc: dmarc-cha...@ietf.org Subject: [dmarc-ietf] Second WGLC for draft-ietf-dmarc-psd All During the IESG reviews of draft-ietf-dmarc-psd, there were several issues raised with some of the document. Most of them are editorial but the one big item was the description of the Experiment. The chairs sat down and broke out the experiment section into three separate experiments, and included language on how to capture the data to confirm how the experiment worked. It's enough of a change that we wanted to do a second working group last call to make sure the working group agrees with our changes. The diff of the current version with the previous version is here: https://www.ietf.org/rfcdiff?url1=draft-ietf-dmarc-psd-08 <https://www.ietf.org/rfcdiff?url1=draft-ietf-dmarc-psd-08&url2=draft-ietf-dmarc-psd-09> &url2=draft-ietf-dmarc-psd-09 This starts a *one* week second working group last call for draft-ietf-dmarc-psd Please review the changes and offer up comments to the working group. This working group last call 20 November 2020 Thanks,
