The sendmail setup should be the same for fedora or Centos.  They
ship sendmail intentionally broken so as not to accept any
mail from outside sources.   The first step, if you haven't
already done it, is to fix the broken part.  Be sure you have
installed the sendmail-devel package
  yum install sendmail-devel
In /etc/mail/sendmail.mc change:
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
to
DAEMON_OPTIONS(`Port=smtp,Name=MTA')dnl
and execute 'make' to rebuild sendmail.cf, then
put all the domain names you wish to accept
thisbox.com
sub.thisbox.com
in the /etc/mail/local-host-names file and
restart sendmail (note that you must restart sendmail after
changing sendmail.cf or local-host-names but not most of
the other files).

To permit outbound email, edit /etc/mail/access
and add lines like
192.168.0 	RELAY
for all your internal network addresses that should
be able to forward mail though this box.  (Other addresses
will only be able to send to destinations configured
as local).  Run 'make' again to rebuild the access database.

Look at /var/log messages to see what is happening. When things
are in the queue you can
sendmail -v -q
to force a delivery attempt and watch the responses.

Centos/fedora should have no differences in capabilities or
configuration.  Because of the nature of the distributions
you'll probably find more people running servers on the
centos list.  And anyone who successfully rebuilds a
sendmail.cf (even with the handy tools) shouldn't be consided
a newbie.
