Mail servers for email.cz
DNS lists 2 mail hosts for email.cz, starting with mx1.seznam.cz. Lower priority values are tried first; the rest exist for failover.
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
For email.cz, verification runs the whole pipeline: syntax, live MX, the open lists, and then the SMTP handshake with the mail host, with no message ever transmitted. Each verdict carries a machine-readable reason.
