Problems

  • !
    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 24 iterations and a 8-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.

Problems

  • !
    Policy: quarantine

  • !
    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
