Now I'm in trouble...

[Bill.Light at kp.org]

I noticed my postfix mail was being rejected by AOL...upon investigating, 
it's because of bad DNS.  I'm guessing that I totally missed what I did, 
because mail used to go from my domain to AOL...now it's not.  In the mail 
log I see:
http://postmaster.info.aol.com/errors/421dnsnr.html

Which basically says my reverse DNS is foobar'd.  The reason I'm in 
trouble is half my wife's friends have AOL...

SBC  gave me 5 usable addresses  66.124.156.120/29  and what I have done 
is:

==> As I understand  120 is the network

121 is their router
122 is my 1st usable address  (it is my 3-NIC firewall)
123 is my web/mail server
124  future use
125  future use
126  future use

what I have:  /etc/named.conf

zone "light-family.com" in {
        type master;
        also-notify {168.143.168.1; 168.143.171.129; 206.13.28.11; 
206.13.29.11; };
        allow-transfer {168.143.168.1; 168.143.171.129; 206.13.28.11; 
206.13.29.11; };
        file "db.light-family.com";
};
zone "hall-brothers.com" in {
        type master;
         file "db.hall-brothers.com";
};
zone "miss-light.com" in {
        type master;
         file "db.miss-light.com";
};
zone "120.156.124.66.in-addr.arpa" in {
        type master;
        file "db.66.124.156.120";
};
zone "123.120.156.124.66.in-addr.arpa" in {
        type master;
        file "db.66.124.156.120.123";
};
zone "123.156.124.66.in-addr.arpa" in {
        type master;
        file "db.66.124.156.123";
};

==============================================

"also-notify" & "allow-transfer" are my registrar's name servers
and SBC's name servers...

I am confused on the 123.120.156.124.66
coexisting with the  123.156.124.66  entry...

Have I at least got /etc/named.conf  correct ?

I am running SuSE 9.2 (2.6.8-24 kernel) with Bind 9.2.4
