-## 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

-# 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.

-## 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_write_locks = dotlock fcntl

-# 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.

-
-# Delay writing mbox headers until doing a full write sync (EXPUNGE and CHECK

-## Mailbox definitions
-##
-
-# Each mailbox is specified in a separate mailbox section. The section name
-# specifies the mailbox name. If it has spaces, you can put the name
-# "in quotes". These sections can contain the following mailbox settings:
-#
-# auto:
-#   Indicates whether the mailbox with this name is automatically created
-#   implicitly when it is first accessed. The user can also be automatically
-#   subscribed to the mailbox after creation. The following values are
-#   defined for this setting:
-# 
-#     no        - Never created automatically.
-#     create    - Automatically created, but no automatic subscription.
-#     subscribe - Automatically created and subscribed.
-#  
-# special_use:
-#   A space-separated list of SPECIAL-USE flags (RFC 6154) to use for the
-#   mailbox. There are no validity checks, so you could specify anything
-#   you want in here, but it's not a good idea to use flags other than the
-#   standard ones specified in the RFC:
-#
-#     \All       - This (virtual) mailbox presents all messages in the
-#                  user's message store.
-#     \Archive   - This mailbox is used to archive messages.
-#     \Drafts    - This mailbox is used to hold draft messages.
-#     \Flagged   - This (virtual) mailbox presents all messages in the
-#                  user's message store marked with the IMAP \Flagged flag.
-#     \Important - This (virtual) mailbox presents all messages in the
-#                  user's message store deemed important to user.
-#     \Junk      - This mailbox is where messages deemed to be junk mail
-#                  are held.
-#     \Sent      - This mailbox is used to hold copies of messages that
-#                  have been sent.
-#     \Trash     - This mailbox is used to hold messages that have been
-#                  deleted.
-#
-# comment:
-#   Defines a default comment or note associated with the mailbox. This
-#   value is accessible through the IMAP METADATA mailbox entries
-#   "/shared/comment" and "/private/comment". Users with sufficient
-#   privileges can override the default value for entries with a custom
-#   value.
-
