This last statement is really what it boils down to.  Running a chrooted
postfix in anything but the simplest configuration is asking for
trouble.

I managed to get it working on some servers some time ago, but gave up
on it.  Anytime I have to setup Postfix, i just unchroot it.  Besides,
if security is your concern, things like Xen and other virtualzation
technologies have made it close to trivial to dedicate a machine just to
running Postfix.
