# ':' separated list of directories under which chrooting is allowed for mail
# processes (ie. /var/mail will allow chrooting to /var/mail/foo/bar too).
# This setting doesn't affect login_chroot or auth_chroot variables.
# WARNING: Never add directories here which local users can modify, that
# may lead to root exploit. Usually this should be done only if you don't
# allow shell access for users. See
# /usr/share/doc/dovecot-common/configuration.txt for more information.
#valid_chroot_dirs =

# Default chroot directory for mail processes. This can be overridden by
# giving /./ in user's home directory (eg. /home/./user chroots into /home).
#mail_chroot =
# Default MAIL environment to use when it's not set. By leaving this empty
# dovecot tries to do some automatic detection as described in
# /usr/share/doc/dovecot-common/mail-storages.txt. There's a few special
# variables you can use:
#
#   %u - username
#   %n - user part in user@domain, same as %u if there's no domain
#   %d - domain part in user@domain, empty if user there's no domain
#   %h - home directory
#
# You can also limit a width of string by giving the number of max. characters
# after the '%' character. For example %1u gives the first character of
# username. Some examples:
#
#   default_mail_env = maildir:/var/mail/%1u/%u/Maildir
#   default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u
#   default_mail_env = mbox:/var/mail/%d/%n/:INDEX=/var/indexes/%d/%n
