Sendmail config/firewall Problem

Hello sendmail group,

I am trying to get sendmail to run on my linux system (Fedora Core
6). I am wishing it would just send log message emails to root. For
some reason my localhost and my local ip are conflicting.
I am using the box primarily as a firewall, running iptables. I have
two network cards, one (eth0) for the internet, and configure via DHCP
from the DSL provider - it has an outside ip address. The other
network card is for my local network (with 3 systems). I am using ip
masquerade, to allow the 3 boxes behind the firewall to access the
internet, etc. It's ip address is 192.168.1.1. I do not want to use
sendmail for anything but on the localhost, which I have named
"ewhlinux" - and set its name and ip in the /etc/hosts file (...
192.168.1.1 ewhlinux).
I also have a line in the hosts file for the localhost.localdomain
which is just 127.0.0.1.

I have removed the sendmail program using rpm -e, and reinstalled it
using the rpm -Uvh, etc to return to a "generic" setup - I seem to
still be missing something. Perhaps someone will see my error?

That describes my setup more or less. I have included here the text
of the "mail" message I get:

The default configuration for sendmail is to accept connections on the
local interface only (lo, or 127.0.0.1). Look for the comments around
the DAEMON_OPTIONS('Port=smtp,Addr=127.0.0.1...) and it should become
clear.

Hello Mark,
I will double check the file. Both my sendmail.mc and sendmail.cf
include the line "DAEMON_OPTIONS('Port=smtp,Addr=127.0.0.1"
I will check the .mc file for info, etc.
Thanks for the reply,
