Hello, Roelof, >From this:
totaal 16 drwxr-xr-x. 2 root root 24 5 jun 13:42 . drwxr-xr-x. 76 root root 8192 5 jun 15:26 .. -rw-r--r--. 1 postfix root 47 5 jun 13:42 smtpd.conf I believe you do not need to change owner/group of smtpd.conf; because postfix user already has access to read the file. You see, you have read+execute on the directory, and read on the file, for all users. So, postfix user *will* access and read the file. The problem is not that. Find it on another place. By the way, which is your distro? Regards!
