Hi,
unfiltered postconf output is overwhelming. Please provide output of
postconf -n.
Also complete loglines of a failed smtp delivery would be very useful.
Seems you are using your host as smarthost, because no relayhost is set.
So it would be helpful to know if you have problems sending mail to all,
or only some, hosts.
