What's keeping thedobuy.org from an A

  1. Mail servers without IPv6
    inbound-smtp.ap-northeast-1.amazonaws.com, receive-apne1.forge.rmta.net 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.
