Can someone send email as you?
The rua and ruf addresses in your DMARC record, and the permission record an outside destination must publish to receive them.
The reports are how you learn who is sending as you. A policy with no reporting address is flying blind.
A failure is a finding in your result. The check is scored, so it can lower your score, and the Full Report gives every finding its severity and a fix. If the check cannot finish, it is recorded as unknown: it carries no penalty, and it is never a pass.
A receiver can still choose not to send reports, which nothing outside can see.
Check 10 is one of 16 in Email authentication. See it in its row on the scanner page, beside the rest of Email authentication.
The DMARC checker runs it on its own. It reads your instruction to inboxes about mail that fails, and whether its reports reach anyone.
The free check includes this one and takes about 30 seconds. No account. Nothing to install.
