personally, I would backup copies of any config files that you altered -
i.e.

cp /etc/postfix/main.cf /etc/postfix/main.cf.saved

and then remove the symlink you created...

rm /usr/sbin/sendmail.postfix

and then reinstall postfix...

rpm -ivh --force \
http://download.fedora.redhat.com/pub/fedora/linux/core/4/i386/os/Fedora/RPMS/postfix-2.2.2-2.i386.rpm

and that should fix things

but I would recomend that you also install the system-switch-mail
package and run that to 'bless' postfix that I described earlier
