Then figure out how to make it work. That should be your one and
only nameserver.

There's no "maybe", check. With a sufficiently recent version of Postfix you
can use:
$ postconf -F smtp/inet/chroot
or
$ postconf -Mf smtp/inet
otherwise, read master.cf. Then if chrooted (explicitly, or by default), check
the resolv.conf file in the chroot jail. Running:
# postfix check
may report whether some files in the chroot differ from those outside.

Not at all clear why logging from the LMTP delivery agent is relevant.
