What's keeping businesscapitalclientupdates.com from an A

  1. Mail servers without IPv6
    _dc-mx.217104053cf7.businesscapitalclientupdates.com has no AAAA record, so mail from IPv6-only servers can't reach it directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
