What's keeping aibusiness.cool from an A

Mail servers without IPv6
mx1.mail.ovh.net, mx2.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.
Nameservers without IPv6
ns200.anycast.me, dns200.anycast.me all have no AAAA record, so a resolver that only speaks IPv6 can't look your domain up. Most DNS providers offer IPv6 nameservers; ask yours, or move DNS to one that does.
