+extra security, but some configuration files are missing or have

+In order
to run inside a chroot jail, the Postfix SMTP client and server
need copies of system configuration files inside the Postfix queue
directory. The exact list of files is very system dependent, but
Check out your Postfix <b>master.cf</b> file. If the SMTP client
runs chrooted, then it needs a bunch of files inside the Postfix
queue directory. Examples are in the source distribution in the
-<b>examples</b> subdirectory.
