mail malady - dns/postfix

[Jerod Prothe]

Greetings all,
On my network, we used to have some NT box acting as the mail exchanger and a 
faulty dns for our domain.  That box has nearly crumbled.  It's still active, 
but no longer accepting mail.  I set up a computer (called galley) with 5.4 and 
it is (supposedly) running authoritative dns for our domain, and is handling 
mail via postfix.  Since I changed the dns, I alerted our registrar, which was 
originally doing lookups for us.
The problem is, now local citizens are trying to send mail to us, but they are 
getting bounce messages reporting that it couldn't talk to otto, the old NT box.



Here is my /etc/namedb/named.conf :

// $FreeBSD: src/etc/namedb/named.conf,v 1.15.2.3 2005/03/23 17:35:58 dougb Exp $
//

options {
         directory       "/etc/namedb";
         allow-query { any; };
         recursive-clients 15000;
         pid-file "/var/run/named/pid";
         forwarders {
                 209.42.72.2;
         };
};

zone "." {
         type hint;
         file "named.root";
};

zone "0.0.127.IN-ADDR.ARPA" {
         type master;
         file "localhost.rev";
};

/*
zone "domain.com" {
         type slave;
         file "s/domain.com/bak";
         masters {
                 192.169.1.1;
         };
};

zone "0.168.192.in-addr.arpa" {
         type slave;
         file "s/0.168.192.in-addr.arpa.bak";
         masters {
                 192.168.1.1;
         };
};
*/

zone "usd217.org" {
         type master;
         file "db.usd217.org";
};

zone "72.42.209.in-addr.arpa" {
         type master;
         file "usd217-reverse";
};

key "rndc-key" {
         algorithm hmac-md5;
         secret "VR7Bsxrqrrtf38pGNzog1A==";
};

controls {
         inet 127.0.0.1 port 953
         allow { 127.0.0.1; } keys { "rndc-key"; };
};


And here is my /etc/namedb/<localzone>:

There may be more at stake here:  If this doesn't work well, then any 
credibility that I have with my employer concerning using open-source may be 
exhausted.  Any other conf's I should show?

Thanks
