About the domain
Its mail is handled by an unrecognised provider.
How Spaw treats addresses at onet.pl
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.
