starting up postfix under fedora 9?

Wed May 14 15:54:06 UTC 2008

    What is the recommended approach under Fedora 9 to configure
postfix to automatically startup at boot? Under Fedora 8, I was
using...

chkconfig --add postfix
chkconfig --levels 2345 on

However this chkconfig setting didn't survive the Fedora 9
upgrade process. Is there a better approach which will allow
postfix to continue to startup after future upgrades (say
to Fedora 10)?
