Yes, have checked with ISP and the reversed DNS record
is added.

or have you modify any settings in the
Sendmail.conf...

As I was told that I need to add those internal IP or
my internal network to enable the reply options of the
Sendmail server.

This error seems the Sendmail server do a reversed
lookup my internal hosts as the IP is the NATed
address of my internal hosts to the DMZ when I'm using
hide behind the interface (which is 0.0.0.0).

Have you disable the NAT for Internal_Net to DMZ_Net?

thanks
Nick
