Up-front listing of DNS domain requirements

Ok, as linked to from elsewhere,

Also, support for wildcard DNS use, records on *.sub on domain.tld. Can be set up in advance for domains. at least A, AAAA, CAA, though in my experience, yunohost generates different DKIM keys for each domain it manages, so some mail records need to be unique. SPF and DMARC can be shared, all of which are stored on TXT records of sub-domains, or sub-sub-domains, of the domains they help attest and validate.

Using these wildcard records can, for now, let you avoid having to add new entries, though you’ll need to diagnose and ignore expected records.
