One finding blocks deliverability.
khnpp.atom.gov.ua has no enforceable DMARC policy, so mail that forges its domain is not blocked at the recipient.
Your DMARC setup is not being read correctly because one of the settings is written in an invalid format. DMARC helps mail providers decide what to do with messages that claim to come from your domain, so a broken record can hurt deliverability and make spoofed email harder to block. Fix it by correcting the DMARC settings in DNS so the policy and reporting tags use valid names and values.
