may be running a Red Hat distribution. If that is the case then there is
a little configuration utility used to switch between sendmail and
postfix that should be a much easier solution. On the Fedora releases
its /usr/sbin/system-switch-mail, it is not installed by default, you
will probably need to install the system-switch-mail rpm. On RHEL
systems its called redhat-switch-mail and is in the redhat-switch-mail
rpm. 

On Red Hat systems we use the "alternatives" mechanism to support
multiple installed subsystems and switch between them. This is done via
symbolic links. If you're a "I program on bare metal" person you can
invoke alternatives directly, the system-switch-mail is just a simple
GUI that wraps "alternatives"
