Bind and MailScanner

I am trying to get mailscanner to send to an isp via smtp. I have the
mailscanner box in the local 192.168.1.x subnet. I set up dns in rh 9.0,
and I have webmin's latest version. I have sendmail sending to a relay
server at the ISP. Webmin bind says it is version *BIND version 9.2.1*

When I run the dig -x 192.168.1.250 command it shows it to belong to an
outside address at internic as opposed to my internal domain:

[root at mail root]# dig -x 192.168.1.250

; <<>> DiG 9.2.1 <<>> -x 192.168.1.250
;; global options:  printcmd
;; Got answer:

;; MSG SIZE  rcvd: 121

So, when I send email from 192.168.1.250 it shows up in the mailscanner
log as being rejected for relay as it can not do a domain lookup on
192.168.1.250. I tried entering a reverse dns record, but that didn't
seem to help.

 From what I could figure, it almost seemed like dns wasn't working from
webmin or something.

Any thoughts?
