yandex kurumsal mail kullanmak istiyorum fakat DNS ile doğrulamayı yapamadım bir türlü

1. Make sure that you chose the correct domain.
   
   If the domain is specified in the service with the "www" prefix but you added a domain record without "www" (or vice versa), the domain won't be confirmed. It may take some time for DNS records to be updated.
2. Add a DNS TXT record for the domain kamber-zinkwaren.com:
   yandex-verification: xxxxxxxxxxxxx
3. После создания записи обновляются не сразу: обычно на обновление уходит до 72 часов (это трое суток).
4. Click "Check" after the records have been updated.

bu ksıımlara ne girmem gerekiyor?
