Turn off CHROOT for the SMTP daemon. http://www.postfix.org/DEBUG_README.html#no_chroot A common mistake is to turn on chroot operation in the master.cf file without going through all the necessary steps to set up a chroot environment. This causes Postfix daemon processes to fail due to all kinds of missing files. The example below shows an SMTP server that is configured with chroot turned off: /etc/postfix/master.cf: # ============================================================= # service type private unpriv chroot wakeup maxproc command # (yes) (yes) (yes) (never) (100) # ============================================================= smtp inet n - n - - smtpd Inspect master.cf for any processes that have chroot operation not turned off. If you find any, save a copy of the master.cf file, and edit the entries in question. After executing the command "postfix reload", see if the problem has gone away. Wietse
