What's keeping cr-consulting-services.com from an A

  1. Mail servers without IPv6
    mx1.spacemail.com, mx2.spacemail.com have no AAAA record, so mail from IPv6-only servers can't reach them directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
