After upgrading a few production servers from CentOS 5.4 to CentOS 5.5, I have identified a potential bug in the upgrade. For some reason the checkconfig setup for postfix gets deleted and postfix doesn't start automatically after a reboot. I couldn't find references to this anywhere else, so posting in hopes that it may help somebody else. This is an easy fix, but something you need to watch for as you update any servers running postfix.
After upgrade and reboot, running chkconfig no longer shows postfix in the list.
[root@mx1 ~]# chkconfig --list

I was able to get to to show up, simply by typing "chkconfig postfix on". I assumed I would need to do "chkconfig --add postfix" to *ADD* it first, but does not appear that this is the case.
[root@mx1 ~]# chkconfig postfix on
