when i have mail_chroot = /var/vmail/ in 10-mail.conf
both doveconf mail_chroot and doveconf -f protocol=lmtp mail_chroot
result is same: mail_chroot = /var/vmail/

when i remove mail_chroot = /var/vmail/ in 10-mail.conf
both result is empty: mail_chroot =

i have only one mail_chroot setting in 10-mail.conf,
but i also have valid_chroot_dirs = /var/vmail/.
is it matter?
