What's keeping amberday.app from an A

  1. Mail servers without IPv6
    mx0.mail.ovh.net, mx2.mail.ovh.net, mx1.mail.ovh.net, mx3.mail.ovh.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.
