What does this mean?

These are public DNS facts about the domain century21.fr. MX records list the servers that accept mail for the domain. SPF and DMARC are DNS policies that help receivers fight spoofing. A catch-all domain accepts mail to every address, so the existence of a single mailbox cannot be confirmed.

This page does not reveal any individual email address or whether a specific mailbox exists — to verify one address, use the email checker.
