Are we talking about RedHat 7.1 or 7.2? If so you need to modify
/etc/mail/sendmail.mc and comment out or remove the line that reads:

DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')

Then you need to build a new sendmail.cf with:

# m4 /etc/mail/sendmail.mc > /etc/sendmail.cf

and restart sendmail (/etc/init.d/sendmail restart). Also note that for
either of those versions of Redhat the default installation will run a
firewall that will prevent access to the SMTP port. You can modify the
firewall rules to allow inbound SMTP or disable the firewall completely with:

# /etc/init.d/ipchains stop
# chkconfig --level 2345 ipchains off

-- 
The instructions said to use Windows 98 or better, so I installed RedHat.
