Wietse,
All of these services are tunning with chroot ENABLED. Check
your $queue_directory/etc/resolv.conf file again.
smtp inet n - y - - smtpd
pickup unix n - y 60 1 pickup
cleanup unix n - y - 0 cleanup
tlsmgr unix - - y 1000? 1 tlsmgr

bounce unix - - y - 0 bounce

verify unix - - y - 1 verify
flush unix n - y 1000? 0 flush
smtp unix - - y - - smtp

showq unix n - y - - showq

retry unix - - y - - error
discard unix - - y - - discard
lmtp unix - - y - - lmtp
anvil unix - - y - 1 anvil
scache unix - - y - 1 scache
$queue_directory/etc/resolv.conf is the same as /etc/resolv.conf. I've also
disabled chroot with the same result. Two points that puzzle me are why the
system does not attempt a SASL connection to the submission port and why
this configuration works in versions 3.1 and 2.9 of Postfix.
