Can an address at sait-kirov.ru receive email?

No MX records are recorded for this domain. This alone does not prove that mail will bounce: some domains receive mail through their A or AAAA records. The disposable classification is separate from mail delivery.

Should I block sait-kirov.ru at signup?

If you need to reach the account holder later, or your product has a free tier, yes. Signups from disposable domains are rarely recoverable customers. If you only need a one-time confirmation, a challenge such as a phone number may be enough.

How do I block sait-kirov.ru and other disposable domains?

Send the address to GET /email/{address}, or the domain to GET /domain/{domain}, and reject the signup when disposable is true. The response covers every domain in the dataset, including ones added today, so there is no list to maintain. The guide to blocking disposable email addresses has code samples.
