I don't think we need to wait that long. I have heard the designated expert for the registry is open to early registration if the chairs determine there is rough consensus for psd=. > I think many of the required tasks can be discussed here.

Does such a role exist? I don't think so. In my experience it's external groups that are interested in a new technology that deal with evangelizing it once developed by the IETF. Since RFCs don't write themselves, there's generally someone. > > From your list further down the thread, why do you think having a psd=y > > tag on gov.uk, police.uk, and mil will have?

They do have a DMARC record. I have no idea why they are different, but that's the best example I've seen so far of a record for which psd=y would be important. Once the tag is assigned, someone should definitely discuss this with CentralNic. If no one on the list knows someone there, my guess is that it's almost a certainty that someone on the list knows someone who does. > > It's not even the ~500 domains on the PSL that have DMARC records > > published > > that we need to concern ourselves with, it's a small subset of them. > > I counted 238 of them, discarding the ones with '*'s.

I'm willing to work on this at the appropriate time and i know others who are as well. I think, for now, we should proceed on the assumption that the evangelization of the psd= tag will get done. It needn't be done overnight as it will have no effect until mail receivers implement the associated processing. That will be the bigger lift in my opinion.
