    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: doug.ns.cloudflare.com: "2026.10.2"; lily.ns.cloudflare.com: "2026.10.2". Hide or replace the version string.

Problems

  • ✗
    21 DNS lookups, over the limit of 10
    SPF · SPF record needs 21 DNS lookups (including nested includes), more than the limit of 10. Receivers will return a permerror; reduce includes or flatten the record. Problems found: include:phxrelay.tbe.taleo.net does not exist or has no records.
    #2
  • !
    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
  • !
    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
    #7
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: us-smtp-inbound-1.mimecast.com, us-smtp-inbound-2.mimecast.com
    #11
  • !
    1 void lookup
    SPF · 1 include/redirect target does not exist or has no records (limit is 2). This usually is a stale include; remove it.
    #26
  • !
    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.
    #32
  • !
    No certificate (a=)
    BIMI · The logo is published without a Verified Mark Certificate. Gmail and Apple Mail only show BIMI logos with a VMC or CMC; Yahoo shows it without one.
