Install the sendmail RPMs if you have not yet done so.
Become root.
cd /etc/mail
Edit sendmail.mc (this is a macro config file)
I would uncomment the line with SMARTHOST and fill in the hostname of 
your outgoing email server.
Type make
restart the sendmail daemon with /etc/init.d/sendmail restart
Configure it to always start with: chkconfig sendmail on

It should work for accepting mail from the local system and forwarding 
it on to your actual email server (the smarthost system).
