What would be the correct behavior with incorrect settings? I guess and error during startup?

We are sorry for not addressing this issue in RHEL-4. As postfix is not
scheduled for an update in RHEL-4.9, I'm closing this bug as WONTFIX. If you
are still experiencing this issue with RHEL-5, please reopen it against RHEL-5.
