What's keeping nv.gov from an A

Mail servers without IPv6
d247857b.ess.barracudanetworks.com, d247857a.ess.barracudanetworks.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.
