What's keeping houseofdata.xyz from an A

  1. Mail servers without IPv6
    mx01.mail.icloud.com, mx02.mail.icloud.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.
