Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns2.hpe.com (glue 16.2.148.110, zone 16.2.141.20); ns5.hpe.com (glue 16.2.141.20, zone 16.2.148.110); ns7.hpe.com (glue 192.170.11.194, zone 16.2.148.110); ns8.hpe.com (glue 192.170.12.194, zone 16.2.132.115). Update the glue at your registrar.

Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

SOA · retry 1h should be shorter than refresh 1h. Current values: refresh 1h, retry 1h, expire 28d, negative TTL 15m.

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.

DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

MX · The following MX hosts could not be resolved to IPv6 addresses: mx0a-002e3701.pphosted.com, mx0b-002e3701.pphosted.com, mxa-002e3701.gslb.pphosted.com, mxb-002e3701.gslb.pphosted.com

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: dkim (1024 bits), s2 (1024 bits). Rotate to a 2048-bit key.

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.
