What's keeping boreale.dev from an A

  1. Mail servers without IPv6
    mx001.dclux.xion.oxcs.net, mx002.dclux.xion.oxcs.net, mx003.dclux.xion.oxcs.net, mx004.dclux.xion.oxcs.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.
