Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns01.elcompanies.com (glue 198.41.222.120, zone 198.41.222.120, 2400:cb00:2049:1::c629:de78); ns02.elcompanies.com (glue 162.159.8.110, zone 162.159.8.110, 2400:cb00:2049:1::a29f:86e); ns03.elcompanies.com (glue 198.41.223.63, zone 198.41.223.63, 2400:cb00:2049:1::c629:df3f). Update the glue at your registrar.

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns01.elcompanies.com: "2026.10.2"; ns02.elcompanies.com: "2026.10.2"; ns03.elcompanies.com: "2026.10.2". Hide or replace the version string.

DNSSEC · The zone is signed but the parent has no DS record, so the signatures are not used. Publish the DS record at your registrar.

DNSSEC · The zone is signed (DNSKEY present) but the parent has no DS record, so the chain of trust is incomplete. Publish the DS record at your registrar.

MX · The following MX hosts could not be resolved to IPv6 addresses: mxa-001a2001.gslb.pphosted.com, mxb-001a2001.gslb.pphosted.com, mx0a-001a2001.pphosted.com, mx0b-001a2001.pphosted.com

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mx (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.
