You probably shouldn't turn off sendmail on a server, at least I never
do.  Out of the box, Fedora (your initial message indicates you're using
FC5) comes with sendmail configured to listen to localhost only.  There
are cron jobs that will run nightly and they will mail their results to
root.  You should either configure sendmail to be a null client for your
real mail server or alias root to another email account so you will
receive this information.  It can be quite important.

I have instructions on how to configure sendmail at
http://www.ultimateevil.org/~jeff/uuasc-2003-04-03.html and this
includes null client configuration in six lines.
