Problems

  • ✗
    Nameserver names don't resolve
    Delegation · These nameservers have no A or AAAA record, so they can't be reached (lame delegation): ec2amaz-cbir0nl.
    #9
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ec2amaz-cbir0nl. dns1.altn.com, dns2.altn.com report NS dns1.altn.com dns2.altn.com ec2amaz-cbir0nl.
    #7
  • !
    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.

Problems

  • !
    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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: sg.mdaemon.com, smtp1.mdaemon.com
    #11
  • !
    Policy in testing mode
    TLS · With mode: testing, senders only report TLS problems (via TLS-RPT) and still deliver without TLS. Switch to mode: enforce once reports are clean.
    #33
  • !
    MX hosts missing from policy
    TLS · These MX hosts are not listed in the MTA-STS policy (mx: mail.mdaemon.com, sg.mdaemon.com): smtp1.mdaemon.com. This will break delivery once the policy is enforced.
    #34
  • !
    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.
