Reverse DNS not working for new server

[dhottinger at harrisonburg.k12.va.us]

I added a new webmail server several weeks ago.  I made the pert. DNS  
entries to the zone file and the reverse lookup file.  Within my  
domain using my DNS servers everything resolves correctly.  When I do  
an nslookup for 204.111.40.8 I get newproxy.harrisonburg.k12.va.us.   
However, outside my domain I get
UnKnown can't find 204.111.40.10: Non-existent domain.  Now the rest  
of my ip's resolve correctly.  Heres my zone file:

$ORIGIN .
$TTL 259200     ; 3 days
harrisonburg.k12.va.us IN SOA ns1.harrisonburg.k12.va.us.  
rlineweaver.harrisonburg.k12.va.us. (
                                 2006112601 ; serial
                                 28800      ; refresh (8 hours)
                                 7200       ; retry (2 hours)
                                 2419200    ; expire (4 weeks)
                                 86400      ; minimum (1 day)
                                 )
                                 NS      ns1.harrisonburg.k12.va.us.
                                 NS      ns2.harrisonburg.k12.va.us.
Heres the entry for newproxy:
newproxy                        A       204.111.40.10

Heres my reverse dns file for this zone:
$ORIGIN .
$TTL 259200     ; 3 days
40.111.204.in-addr.arpa         IN SOA  ns1.harrisonburg.k12.va.us.  
rlineweaver.harrisonburg.k12.va.us. (
                                 2006112601  ; serial
                                 28800      ; refresh (8 hours)
                                 7200       ; retry (2 hours)
                                 2419200    ; expire (4 weeks)
                                 86400      ; minimum (1 day)
                                 )
                         NS      ns1.harrisonburg.k12.va.us.
                         NS      ns2.harrisonburg.k12.va.us.
Heres the entry for Newproxy in reverse dns
10                      PTR     newproxy.harrisonburg.k12.va.us.

Heres my named.conf spelling out my upstream dns notifiers:
options {
         directory "/var/named";

         forward first;
         forwarders {
                 204.111.1.36;
                 204.111.1.35;
         };
Ive added several servers in the past with no issues.  Im using bind  
9.2.3.  I cant figure out why other servers arent getting the updates.  
  Im not seeing any error's logged at all.

thanks,
