Apologies for filing this under "sendmail" but Bugzilla for pinstripe does
not have a "postfix" component.  Postfix is an MTA on the Powertools CD.

The chrooted directories are not included in the postfix RPM off of the
pinstripe Powertools CD.  From the RPM install:

<snip>
[pjl@maynard RPMS]$ sudo rpm -Uvh postfix-20000531-5.i386.rpm
postfix                     ##################################################
install: installing multiple files, but last argument
(/var/spool/postfix/etc) is not a directory
Try `install --help' for more information.
ln: create symbolic link `/var/spool/postfix/usr/lib/zoneinfo' to
`/etc/localtime': No such file or directory
<snip>

A listing of the RPM reveals that the following directories are not included:

/var/spool/postfix/etc
/var/spool/postfix/lib
/var/spool/postfix/maildrop
/var/spool/postfix/usr/lib/zoneinfo

Add the following to %files in the spec file:

%dir %attr(-, root, root) %verify(not md5 size mtime) %{queue_directory}/etc
%dir %attr(-, root, root) %verify(not md5 size mtime) %{queue_directory}/lib
%dir %attr(-, root, root) %verify(not md5 size mtime)
%{queue_directory}/usr/lib/zoneinfo

and all will be happy...
