First, make sure logging works: $ postlog -p warn -t postfix/test "warning: this is a test". find the log message in the log file. If that shows up, but still cleanup warnings in the same file, then look for inadvertent or unwanted settings of "receive_override_options" that might disable header checks. And of course do look into chroot issues as suggested by Wietse. -- Viktor.
