Problems

  • ✗
    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: ns1.argewebhosting.eu (31.25.98.210): read tcp 46.225.38.91:33174->31.25.98.210:53: i/o timeout; ns1.argewebhosting.eu (2a05:1500:702:0:1c00:eff:fe00:ce): read tcp [2a01:4f8:1c1c:eebf::1]:56250->[2a05:1500:702:0:1c00:eff:fe00:ce]:53: i/o timeout.
    #19
  • ✗
    Invalid contact address
    SOA · The SOA RNAME "hostmaster\\@argeweb.nl" contains an @; it must be written with a dot instead (hostmaster.example.com).
    #25
  • !
    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 1 iteration and a 1-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
    DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.
    #4
  • !
    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
  • !
    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.
