Because you don't serve 164.69.212.in-addr.arpa and you
tried to access the cache. You should slave
164.69.212.in-addr.arpa so you have the CNAMEs locally.
This will also make the above dig directed at your server
work as the answer will come from the zone rather than
the cache.
Note: the lookups are working remotely because interative
resolvers ask for 57.48-28.164.69.212.in-addr.arpa rather
that 57.164.69.212.in-addr.arpa as generated by the above
dig.

Mark
P.S. Complain to your MUA vendor. Quoted printable is supposed to
be readable by people that don't support mime. Spaces should stay
as spaces. They should not be converted to 0xA0 because html doesn't
like multiple spaces.
