Sure is this possible. Just setup the second NIC and tell Apache2 and
Sendmail to not bind to this IP:

Apache2 -> Listen directive in httpd.conf
Sendmail -> DAEMON_OPTIONS directive in sendmail.mc

I just wonder about your comment, both daemons would only bind to the
NIC #2 (private address space). This is nothing from default. If in
doubt post your /etc/sysconfig/network-scripts/ifcfg-eth{0,1} config
files.

OK...so here's what happens.  I activate the second NIC (eth1) and internet
browsing is unavailable on the server.  Going to an outside line, I try
going into a web page or checking email.  Both fail. I can't even ping my IP
address.  Inside on the LAN, Samba doesn't respond properly.  Computers know
it's there, but nothing can connect.  I checked the Firewall Options in the
Security Level panel and set eth1 to a trusted interface.  However, no
change in behavior.  I deactivate eth1 and just leave eth0 running, web and
outside lines are all happy again.  

So below is my ifcfg files.  Let me know what you think...
THANKS!
