It doesn't matter where you add it, as long as the "doveconf -n" output
looks correct.

Looks right.

Is there another mail_chroot setting elsewhere? The important thing is
that when you do:

doveconf mail_chroot

it shows the chroot, but when you do:

doveconf -f protocol=lmtp mail_chroot

the result should be empty.
