    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns1.vkontakte.ru (2a00:bdc0:ff:1::2): read udp [2a01:4f8:1c1c:eebf::1]:43985->[2a00:bdc0:ff:1::2]:53: i/o timeout; ns2.vkontakte.ru (2a00:bdc0:ff:2::2): read udp [2a01:4f8:1c1c:eebf::1]:58424->[2a00:bdc0:ff:2::2]:53: i/o timeout; ns3.vkontakte.ru (2a00:bdc0:ff:3::2): read udp [2a01:4f8:1c1c:eebf::1]:41385->[2a00:bdc0:ff:3::2]:53: i/o timeout; ns4.vkontakte.ru (2a00:bdc0:ff:4::2): read udp [2a01:4f8:1c1c:eebf::1]:36205->[2a00:bdc0:ff:4::2]:53: i/o timeout.

    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

  • !
    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
  • !
    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: mx.vk.com
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    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.
