Chroot and multiple instance support are, or should be, handled properly by the Postfix init scripts. If you are using a distro Postfix package, these scripts are written and maintained by distro staff. For a thorough description of the cause of this problem, and fixes, it is worth the time to read this: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=560682 Even if you're using something other than Debian, the knowledge gained from this doc is valuable in understanding the issue. -- Stan
