    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 100 iterations and a 16-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 not reachable
    TLS · The MTA-STS record exists but the policy could not be fetched, so senders ignore MTA-STS: https://mta-sts.datenschutz-mv.de/.well-known/mta-sts.txt returned HTTP 403.
    #33
  • !
    Policy: quarantine
    DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.
    #4
  • !
    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.
    #7
  • !
    Addresses without reverse DNS
    MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 2a02:1006:c000:0:194:25:109:19 (mx03.mvnet.de), 2a02:1006:c000:0:194:25:109:20 (mx04.mvnet.de). Ask your hosting provider to set one.
