The default RedHat setup (for 7.x anyway) has relaying disabled by

Find /etc/sendmail.mc or /etc/mail/sendmail.cf (depending on where it
is in a RH8 box).

You need to comment out (prefix 'dnl ') to the four line below (I've
left the comment in):

dnl This changes sendmail to only listen on the loopback device
dnl and not on any other network devices. Comment this out if you
dnl to accept email over the network.
DAEMON_OPTIONS(`Port=smtp,Addr=, Name=MTA')

Then run it through m4 to create your new sendmail.cf file.
