I have a big problem with the new requirement to set DS or DSKEY records: the registrar of my domains (Freenom) does not offer this option. I can set a NS record, that’s it.
I fear the currently - quite nice - e-mails might change soonish to “do what we request or your domain gets suspended”. I would like to do that, but as I said, they don’t offer that feature.
So what now!? It would be great to exclude hobby projects or domains hosted by … not the best registrars in the world … from your rule.
