yes, like you said

root at shell:[/etc/dovecot/conf.d]# doveconf -f protocol=imap mail_chroot
mail_chroot = /var/vmail/
root at shell:[/etc/dovecot/conf.d]# doveconf -f protocol=lmtp mail_chroot
mail_chroot =

but still have the error
Couldn't drop privileges: Process is already chrooted, can't un-chroot 
for this user

and lmtp can not delivery mail
