    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: gwa.fe.bosch.de (glue 194.39.219.2, 2a03:cc00:ff0:2f02::10, zone 194.39.219.2, 2a03:cc00:ff0:2f02::10, 2a03:cc00:ff0:200a::d); gwa2.fe.bosch.de (glue 103.4.124.215, 2401:d00:ff0:2f01::11, zone 103.4.124.215, 2401:d00:ff0:2f01::11, 2401:d00:ff0:2003::8). Update the glue at your registrar.

Problems

  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: buderus-de.mail.protection.outlook.com
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    No aggregate reports (rua)
    DMARC · DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...
    #19
  • !
    Subdomains unprotected (sp=none)
    DMARC · DMARC subdomain policy is sp=none, so spoofed mail from subdomains is not blocked. Consider sp=quarantine or sp=reject.
    #20
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits), selector1 (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    Not configured
    TLS · MTA-STS or DANE is used without TLS-RPT, so you get no reports when senders fail to deliver because of TLS problems. Publish _smtp._tls TXT "v=TLSRPTv1; rua=mailto:...".
