What's keeping cicku.me from an A

  1. Mail servers without IPv6
    mxb.global.inbound.cf-emailsecurity.net, mxa.global.inbound.cf-emailsecurity.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.
