Problems

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns01.mostware.nl: "9.16.27-Debian"; ns02.mostware.nl: "9.16.27-Debian". Hide or replace the version string.

  • !
    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 10 iterations and a 0-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.

    4 of 10 DNS lookups, with problems

  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits), selector1 (1024 bits), selector2 (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    2 void lookups
    SPF · 2 include/redirect targets does not exist or has no records (limit is 2). This usually is a stale include; remove it.
    #26
  • !
    Not configured
    TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
