-## Mailbox locations and namespaces
-##
-
-# Location for users' mailboxes. This is the same as the old default_mail_env
-# setting. The default is empty, which means that Dovecot tries to find the
-# mailboxes automatically. This won't work if the user doesn't have any mail
-# yet, 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 = 
-
-# If you need to set multiple mailbox locations or want to change default
-# namespace settings, you can do it by defining namespace sections.
-# NOTE: Namespaces currently work ONLY with IMAP! POP3 and LDA currently ignore
-# namespaces completely, they use only the mail_location setting.
-#
-# You can have private, shared and public namespaces. The only difference
-# between them is how Dovecot announces them to client via NAMESPACE
-# extension. Shared namespaces are meant for user-owned mailboxes which are
-# shared to other users, while public namespaces are for more globally
-# accessible mailboxes.
-#
-# REMEMBER: If you add any namespaces, the default namespace must be added
-# explicitly, ie. mail_location does nothing unless you have a namespace
-# without a location setting. Default namespace is simply done by having a
-# namespace with empty prefix.
-#namespace private {
-   # Hierarchy separator to use. You should use the same separator for all
-   # namespaces or some clients get confused. '/' is usually a good one.
-   # The default however depends on the underlying mail storage format.

-   # extension. You'll most likely also want to set list=no. This is mostly
-   # useful when converting from another server with different namespaces which

-   # hidden namespaces with prefixes "~/mail/", "~%u/mail/" and "mail/".

-## mbox-specific settings
-##
-
-# Which locking methods to use for locking mbox. There are four available:
-#  dotlock: Create <mailbox>.lock file. This is the oldest and most NFS-safe
-#           solution. If you want to use /var/mail/ like directory, the users
-#           will need write access to that directory.
-#  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
-# them simultaneously.
-#mbox_read_locks = fcntl
-#mbox_write_locks = dotlock fcntl

-#mbox_dotlock_change_timeout = 120

-# When mbox changes unexpectedly we have to fully read it to find out what
-# changed. If the mbox is large this can take a long time. Since the change
-# is usually just a newly appended mail, it'd be faster to simply read the
-# new mails. If this setting is enabled, Dovecot does this but still safely
-# fallbacks to re-reading the whole mbox file whenever something in mbox isn't
-# how it's expected to be. The only real downside to this setting is that if
-# some other MUA changes message flags, Dovecot doesn't notice it immediately.
-# Note that a full sync is done with SELECT, EXAMINE, EXPUNGE and CHECK 
-# commands.
-#mbox_dirty_syncs = yes

-#mbox_very_dirty_syncs = no
-
-# Delay writing mbox headers until doing a full write sync (EXPUNGE and CHECK

-  #   quota2 = dict:domain:%d:proxy::quota_domain
-  #   quota_rule = *:storage=102400
-  #   quota2_rule = *:storage=1048576
-  # Gives each user their own 100MB quota and one shared 1GB quota within
-  # the domain.
-  #
-  # You can execute a given command when user exceeds a specified quota limit.
-  # Each quota root has separate limits. Only the command for the first
-  # exceeded limit is excecuted, so put the highest limit first.
-  # Note that % needs to be escaped as %%, otherwise "% " expands to empty.

-  # ACL plugin. vfile backend reads ACLs from "dovecot-acl" file from maildir
-  # directory. You can also optionally give a global ACL directory path where
-  # ACLs are applied to all users' mailboxes. The global ACL directory contains
-  # one file for each mailbox, eg. INBOX or sub.mailbox. cache_secs parameter
-  # specifies how many seconds to wait between stat()ing dovecot-acl file
-  # to see if it changed.
-  #acl = vfile:/etc/dovecot-acls:cache_secs=300

-  # converted to destination storage (mail_location) when the user logs in.
-  # The existing mail directory is renamed to <dir>-converted.

-  # Trash plugin. When saving a message would make user go over quota, this
-  # plugin automatically deletes the oldest mails from configured mailboxes
-  # until the message can be saved within quota limits. The configuration file
-  # is a text file where each line is in format: <priority> <mailbox name>
-  # Mails are first deleted in lowest -> highest priority number order
-  #trash = /etc/dovecot-trash.conf
-
-  # Expire plugin. Mails are expunged from mailboxes after being there the
-  # configurable time. The first expiration date for each mailbox is stored in
-  # a dictionary so it can be quickly determined which mailboxes contain
-  # expired mails. The actual expunging is done in a nightly cronjob, which
-  # you must set up:
-  #   dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool
-  #expire = Trash 7 Spam 30

-
-  # Lazy expunge plugin. Currently works only with maildirs. When a user
-  # expunges mails, the mails are moved to a mailbox in another namespace
-  # (1st). When a mailbox is deleted, the mailbox is moved to another namespace
-  # (2nd) as well. Also if the deleted mailbox had any expunged messages,
-  # they're moved to a 3rd namespace. The mails won't be counted in quota,
-  # and they're not deleted automatically (use a cronjob or something).
