What's keeping xn--80ahcnaul4e.com from an A

The certificate served over IPv6 is wrong
The certificate served over IPv6 at 2a0a:7d80:1:7::168 isn't valid for xn--80ahcnaul4e.com: DEPTH_ZERO_SELF_SIGNED_CERT. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2a0a:7d80:1:7::168 serves the same certificate as your IPv4 address.
Mail servers without IPv6
mx.hoster.by has no AAAA record, so mail from IPv6-only servers can't reach it directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
