    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mxi0.daemon.convar.com, mxi1.daemon.convar.com

  • !
    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.
