  • ✗
    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: dns01.sahibinden.com (85.153.147.101): dial tcp 85.153.147.101:53: connect: connection refused; dns02.sahibinden.com (85.153.147.102): dial tcp 85.153.147.102:53: connect: connection refused; dns03.sahibinden.com (35.195.18.111): dial tcp 35.195.18.111:53: i/o timeout; dns04.sahibinden.com (85.153.138.101): dial tcp 85.153.138.101:53: connect: connection refused; dns05.sahibinden.com (85.153.138.102): dial tcp 85.153.138.102:53: connect: connection refused.

    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    No EDNS
    Nameservers · These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: dns01.sahibinden.com (85.153.147.101), dns02.sahibinden.com (85.153.147.102), dns03.sahibinden.com (35.195.18.111), dns04.sahibinden.com (85.153.138.101), dns05.sahibinden.com (85.153.138.102).

    Unusual SOA timers
    SOA · refresh 5m is outside 20m–1d; retry 5m should be shorter than refresh 5m; expire 5m is shorter than 7d; secondaries stop answering too soon when the primary is down; expire 5m must be longer than refresh + retry. Current values: refresh 5m, retry 5m, expire 5m, negative TTL 5m.

    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

Problems

  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    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
  • !
    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.
