-## Mailbox locations and namespaces
-##
-
-# Location for users' mailboxes. The default is empty, which means that Dovecot
-# tries to find the mailboxes automatically. This won't work if the user
-# doesn't yet have any mail, so you should explicitly tell Dovecot the full
-# location.
-#
-# If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u)
-# isn't enough. You'll also need to tell Dovecot where the other mailboxes are
-# kept. This is called the "root mail directory", and it must be the first
-# path given in the mail_location setting.
-#
-# There are a few special variables you can use, eg.:
-#
-# %u - username
-# %n - user part in user@domain, same as %u if there's no domain
-# %d - domain part in user@domain, empty if there's no domain
-# %h - home directory
-#
-# See doc/wiki/Variables.txt for full list. Some examples:
-#
-# mail_location = maildir:~/Maildir
-# mail_location = mbox:~/mail:INBOX=/var/mail/%u
-# mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n
-#
-# <doc/wiki/MailLocation.txt>
-#
-mail_location = mdbox:~/mail
-
-# If you need to set multiple mailbox locations or want to change default
-# namespace settings, you can do it by defining namespace sections.
-#
-# You can have private, shared and public namespaces. Private namespaces
-# are for user's personal mails. Shared namespaces are for accessing other
-# users' mailboxes that have been shared. Public namespaces are for shared
-# mailboxes that are managed by sysadmin. If you create any shared or public
-# namespaces you'll typically want to enable ACL plugin also, otherwise all
-# users can access all the shared mailboxes, assuming they have permissions
-# on filesystem level to do so.

-# dotlock_try: Same as dotlock, but if it fails because of permissions or
-# because there isn't enough disk space, just skip it.
-# fcntl : Use this if possible. Works with NFS too if lockd is used.
-# flock : May not exist in all systems. Doesn't work with NFS.
-# lockf : May not exist in all systems. Doesn't work with NFS.
-#
-# You can use multiple locking methods; if you do the order they're declared
-# in is important to avoid deadlocks if other MTAs/MUAs are using multiple
-# locking methods as well. Some operating systems don't allow using some of
