What this means for your email list
What this means for addresses at this domain
The domain accepts mail, but whether a given person's mailbox exists depends on that organisation. Company domains often have staff who left, role mailboxes like info@ and sales@, and sometimes catch-all rules that accept everything. Verify the individual address before you send.
Sender authentication
volny.cz has DMARC in monitoring mode (p=none). It collects reports but does not yet block spoofed mail, so the domain is easier to impersonate.
