 then, ideally, the stuff that creates the chroot jail needs to be moved into
 a separate "helper" script that can be run in its own context

 and the postfix.te script needs to have these added:

	 allow postfix_cleanup_t postfix_cleanup_t:capability { sys_chroot };
	 allow postfix_master_t postfix_master_t:capability { sys_chroot };
	 allow postfix_pickup_t postfix_pickup_t:capability { sys_chroot };
	 allow postfix_qmgr_t postfix_qmgr_t:capability { sys_chroot };

 and possibly more?  i am only running a local-delivery-only postfix.


 or, i am sure that there are people on this list who can think of a
 safe way to do this.
