What's keeping atualizacaoclientes.click from an A

Mail servers without IPv6
route1.mx.cloudflare.com, route2.mx.cloudflare.com, route3.mx.cloudflare.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.
