Problems

  • ✗
    Nameserver names don't resolve
    Delegation · These nameservers have no A or AAAA record, so they can't be reached (lame delegation): comserv2.ensae.fr.
    #9
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: comserv2.ensae.fr; only in the zone: dnsext2.ensai.fr, reld01.insa-rennes.fr. dnsext.ensai.fr, dnsext2.ensai.fr, reld01.insa-rennes.fr report NS dnsext.ensai.fr dnsext2.ensai.fr reld01.insa-rennes.fr.

Problems

  • !

  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: esa1.hc610-89.eu.iphmx.com, esa2.hc610-89.eu.iphmx.com

  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits), mta (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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.
