>From my point of view, (sub)domain delegation is the best solution so far. It appears that some brands are using DNS services that can not deal with rfc1034/5 non-compliant records (such as _domainkey or _dmarc). But even the simple delegation setup (no other records than NS records in the zone) doesn't seems so easy for everyone. We recently also had to debug _several_ DNS services providers whose SOA servers wasn't replying the same thing. Best solution, but still far from full automation. The organizational domain is a bit more flexible, but usually the brand doesn't want to do half of the DNS job: either all setup (SPF, DMARC, DKIM), or the minimum (delegation). Benjamin
