Mail not working after install

[Ralph Brown]

After setting up Bind 9.1 on my RH node, the DNS name resolution is working
fine, but now I notice in my maillog  that I am getting an error message
that host name has no address:

Oct 17 17:38:51 www postfix/smtpd[12385]: warning: 66.120.4.162: hostname
policing.net verification failed: Host name has no address
Oct 17 17:38:51 www postfix/smtpd[12385]: connect from unknown[66.120.4.162]
Oct 17 17:38:51 www postfix/smtpd[12385]: 66F0CEBF06:

Oct 17 17:38:51 www postfix/smtpd[12385]: reject: RCPT from
unknown[66.120.4.162]: 554 <php4u at pacbell.net>: Recipient address rejected:

Oct 17 17:39:00 www postfix/smtpd[12385]: disconnect from
unknown[66.120.4.162]

The web server and mail are both on the same RH box. Mail has worked fine
before starting up named. When I turn named off, then I can send/receive
mail just fine. Here the problem is sending mail. Is someone send me mail, I
get it. But if try to send from server account: mail.policing.net, I get the
error???

My ISP has DNS pointing both my domain name and mail account to my static
IP.
I noticed that I don't have a "zone" setup, ot the static ip even mentioned
in my named.conf or one of the files in /var/named. Do I need to add the
static ip# somewhere?

Resolv.conf = 

#domain policing.net
#search pacbell.net
search policing.net
nameserver 192.168.123.139 # RH ip#
nameserver 127.0.0.1
nameserver 206.13.28.12 # pacbell dns
#nameserver 206.13.30.12 # pacbell dns
