So you are on Debian then, be aware that Debian's repackaging of Postfix breaks "postfix upgrade-configuration", "postfix set-permissions", etc. The fix is to reconcile postfix-files with reality. Also, if using multiple instances, to fix the definition of the dynamicmaps.cf entry so it is global rather than per-instance. I think Scott K. was looking into improving the Debian Postfix package, not sure how far along that effort might be. -- Viktor.
