Mail servers without IPv6 mx.stackmail.com 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.
Nameservers without IPv6 ns3.serverbyt.in, ns2.serverbyt.in, ns1.serverbyt.in, ns4.serverbyt.in 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.
