hotbox.ru MX records
hotbox.ru publishes a single MX host, mx.yandex.net. With no backup host, a sender that can't reach it queues the message and retries until the server answers or the queue gives up.
4 other domains we checked on the same day also hand their mail to Yandex Mail servers, with different records from hotbox.ru: inbox.kz, yandex.by, yandex.com.tr and yandex.kz.
hotbox.ru SPF record
The record on 5 November 2026 was v=spf1 redirect=_spf.yandex.net.
In plain terms, it delegates to _spf.yandex.net. The top level uses 1 DNS-querying term; SPF allows 10 in total including nested includes (RFC 7208 §4.6.4).
hotbox.ru DMARC policy
_dmarc.hotbox.ru returned no DMARC record on 5 November 2026. Receivers therefore get no instruction about mail that fails SPF and DKIM, which makes @hotbox.ru easier to spoof (RFC 7489).
Can you verify @hotbox.ru addresses?
Our checker treats @hotbox.ru like any domain: syntax, MX, disposable and role checks first, then a made-up address to rule out a catch-all, then your address at RCPT TO, disconnecting without sending. We have not published a test of how mx.yandex.net answers for @hotbox.ru, so we make no claim here about whether single mailboxes can be confirmed; each result carries its own reason.
Cleaning a list with these addresses
DNS tells you where mail goes, not whether one person's mailbox still exists. For a list, run the whole file through a verifier before you send: invalid rows come out, risky rows (catch-all, unknown, refused) go in their own segment, and valid rows are safe to mail.
