Sorry, I am new on this list and not fully aware of your conventions. So here they are: drwxr-xr-x 20 root root 4096 jul 10 09:32 / drwxr-xr-x 113 root root 12288 jul 13 14:09 /etc -rw-r--r-- 2 root root 1277 jun 24 2007 /etc/nsswitch.conf -rw-r--r-- 1 root root 47 jul 13 14:09 /etc/resolv.conf > > And postfix does get answers from named.

I think postfix does need DNS assistance to check a number of thins. I understand that I don't need to run named on my own machine, as I just could use any nameserver, but running named here gives me greater control, and I can poke into logs etc. > > > > - Running Postfix chrooted without providing the necessary files > > > in the chroot jail. > > > > Postfix is not chrooted. > > If you are not willing to show the evidence, then we cannot > help you find the mistake. OK, here are the relevant lines of master.cf. I adderd the -v option to get more debugging. Still it does not show me communication with the name server. The name server log does show some communication, that stems from postfix, but it does not show me the responses. I would like to see what named tells postfix. # ========================================================================== # service type private unpriv chroot wakeup maxproc command + args # (yes) (yes) (yes) (never) (100) # ========================================================================== smtp inet n - y - - smtpd -v best regards keld
