What DMARC cares about is the Organizational Domain (OD), as a fallback when no DMARC record is found at the desired domain name. That is, PSL is literally outside the scope of DMARC. At the least, therefore, the DMARC specification should define a distinct interface to the outside functionality that tells DMARC where the OD is, which will return what suffix of the full domain name is the OD -- eg, getOrgDomain(full-domain) -> org-domain-suffix The PSL-related side of that interface should be a separate specification, so that changes to its behavior -- such as has been happening with the introduction of ODs that are TLDs or are otherwise 'above' where DMARC has been guessing the OD to be -- are isolated from DMARC. The current problems are that DMARC has embedded too much detail about the PSL world, yet DMARC has no involvement in that world. The current proposal embeds assumptions of PSL knowledge further, rather than separating PSL knowledge out. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net
