Some DNS providers answer for every DKIM name with one wildcard record, often v=DKIM1; p=. Import current records on a domain's DNS page used to add a copy of it for each of about 30 common DKIM names. It now imports it once, as *._domainkey, and keeps any DKIM record that has its own key.
No more dozens of identical DKIM records after an import
**Import current records** now brings in a wildcard DKIM record once, instead of one identical record for every DKIM name it checked.
