need help with BIND9

["lists@pgrworld.com" <lists@pgrworld.com>]

Hello,

I need help setting up nameservers for my own domain.  The IPs and 
domains have been changed for privacy ;-)

I have a static IP on an ADSL line (i.e public IP 1.1.1.1).
I have a router that has a DMZ set up that is pointing to my deb box 
(local IP 10.10.10.10)
I have a domain (mydomain.com) that I bought and I've set it up to point 
to NS1.MYDOMAIN.COM at the public IP 1.1.1.1

I want to set up my deb box as a web/ftp/nameserver server with 
MySQL/PHP on it.

So far, I've configured LAMP on it. I'm having problems with BIND (or so 
I think).  I've read all over that "DNS IS A SIMPLE BUT EASILY 
MISCONFIGURED SYSTEM"

I've confirmed that NS1.MYDOMAIN.COM points to 1.1.1.1 as 
http://ns1.mydomain.com produces my apache page

I'm using BIND9. 

named.conf has this line at the bottom:

                       include "/etc/bind/named.conf.local";


my named.conf.local has this:

zone "mydomain.com" {
       type master;
       file "/etc/bind/mydomain.db";
};

zone "10.10.10.in-addr.arpa" {
       type master;
       file "/etc/bind/10.10.10.rev";
};


my mydomain.db has this:

; BIND data file for mydomain.db
; /var/named/mydomain.db
;
$TTL 1h
@ SOA ns1.mydomain.com. root.mydomain.com. (
 2007110805; Serial (date + two digit serial)
 10800 ; Refresh (3 hours)
 3600 ; Retry (1 hour)
 86400 ; Expire (1 day)
 60 ) ; Default TTL 1 min
 NS ns1.mydomain.com.
 MX mail.mydomain.com.
 A 1.1.1.1

	ns1	A	1.1.1.1
	mail	A	1.1.1.1
	www	A	1.1.1.1


It has been over 5 days, and www.mydomain.com still has not resolved to 
1.1.1.1
What could be the problem?
DIG only produces a QUESTION SECTION but no answers,etc:

I've also done a zonecheck report, and right away it spits out "Unable 
to find primary nameserver (SOA)"

Please help!  Thank you very much!
