    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns3.keysight.com (192.25.21.142): read udp 46.225.38.91:38012->192.25.21.142:53: i/o timeout.

    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns3.keysight.com. pdns111.ultradns.biz, pdns111.ultradns.com, pdns111.ultradns.net, pdns111.ultradns.org report NS ns3.keysight.com pdns111.ultradns.biz pdns111.ultradns.com pdns111.ultradns.net pdns111.ultradns.org.

    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.

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mxa-003cac01.gslb.pphosted.com, mxb-003cac01.gslb.pphosted.com

    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits), dkim (1024 bits), selector1 (1024 bits). Rotate to a 2048-bit key.

  • !
    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.
