I don't know if mx1.freebsd.org delays or refuses delivery when DNS
reverse lookup fails for the source of incoming connections, but
at least there are some problems in the delegation under
2.0.0.2.ip6.arpa: out of 4 authoritative servers,
ns-arin.6to4.nro.net seems to be down, and ns-ripe.6to4.nro.net
returns SEVFAIL.  You should probably contact dns-admin at apnic.net,
which is the maintainer mail address according to the SOA record of
the 2.0.0.2.ip6.arpa zone.
