Mail servers for onet.pl
onet.pl publishes 1 MX record. Senders deliver to the lowest-priority host first, mx.poczta.onet.pl, and fall back down the list if it does not answer.
Who runs the mail
The hosts match the pattern of an unrecognised provider. The mail hosts do not match a known provider pattern, so the domain is probably self-hosted or on a smaller provider. Catch-all behaviour varies from server to server, which is exactly why a mailbox-level probe, not the MX record, decides whether an address exists.
What this means for verification
An address at onet.pl passes the free checks (syntax, MX, lists), so the API goes on to the mailbox-level SMTP handshake, which ends before any message is sent. The result is deliverable, risky, or undeliverable with a reason field that names the evidence.
