+## 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.

+# Which locking methods to use for locking mbox. There are four available:

+#           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.
+#
+# The Debian value for mbox_write_locks differs from upstream Dovecot. It is

+# 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

+# For the sql passdb module, you'll need a database with a table that
+# contains fields for at least the username and password. If you want to
+# use the user@domain syntax, you might want to have a separate domain
+# field as well.
+#
+# If your users all have the same uig/gid, and have predictable home
+# directories, you can use the static userdb module to generate the home
+# dir based on the username and domain. In this case, you won't need fields
+# for home, uid, or gid in the database.
+#
+# If you prefer to use the sql userdb module, you'll want to add fields
+# for home, uid, and gid. Here is an example table:
+#
+# CREATE TABLE users (
+#     username VARCHAR(128) NOT NULL,
+#     domain VARCHAR(128) NOT NULL,
+#     password VARCHAR(64) NOT NULL,
+#     home VARCHAR(255) NOT NULL,
+#     uid INTEGER NOT NULL,
+#     gid INTEGER NOT NULL,
+#     active CHAR(1) DEFAULT 'Y' NOT NULL
+# );

+# HA / round-robin load-balancing is supported by giving multiple host

+#   Basic options emulate PostgreSQL option names:

+#
+#   But also adds some new settings:
+#     client_flags           - See MySQL manual
+#     ssl_ca, ssl_ca_path    - Set either one or both to enable SSL
+#     ssl_cert, ssl_key      - For sending client-side certificates to server
+#     ssl_cipher             - Set minimum allowed cipher security (default: HIGH)
+#     ssl_verify_server_cert - Verify that the name in the server SSL certificate
+#                              matches the host (default: no)
+#     option_file            - Read options from the given file instead of

+# passdb query to retrieve the password. It can return fields:
+#   password - The user's password. This field must be returned.
+#   user - user@domain from the database. Needed with case-insensitive lookups.
+#   username and domain - An alternative way to represent the "user" field.
+#
+# The "user" field is often necessary with case-insensitive lookups to avoid
+# e.g. "name" and "nAme" logins creating two different mail directories. If
+# your user and domain names are in separate fields, you can return "username"
+# and "domain" fields instead of "user".
+#
+# The query can also return other fields which have a special meaning, see
+# http://wiki2.dovecot.org/PasswordDatabase/ExtraFields
+#
+# Commonly used available substitutions (see http://wiki2.dovecot.org/Variables
+# for full list):
+#   %u = entire user@domain
+#   %n = user part of user@domain
+#   %d = domain part of user@domain
+# 
+# Note that these can be used only as input to SQL query. If the query outputs
+# any of these substitutions, they're not touched. Otherwise it would be
+# difficult to have eg. usernames containing '%' characters.
+#
+# Example:
+#   password_query = SELECT userid AS user, pw AS password \
+#     FROM users WHERE userid = '%u' AND active = 'Y'
+#
+#password_query = \
+#  SELECT username, domain, password \
+#  FROM users WHERE username = '%n' AND domain = '%d'
+
+# userdb query to retrieve the user information. It can return fields:
+#   uid - System UID (overrides mail_uid setting)
+#   gid - System GID (overrides mail_gid setting)
+#   home - Home directory
+#   mail - Mail location (overrides mail_location setting)
+#
+# None of these are strictly required. If you use a single UID and GID, and
+# home or mail directory fits to a template string, you could use userdb static
+# instead. For a list of all fields that can be returned, see
+# http://wiki2.dovecot.org/UserDatabase/ExtraFields
+#
+# Examples:
+#   user_query = SELECT home, uid, gid FROM users WHERE userid = '%u'
+#   user_query = SELECT dir AS home, user AS uid, group AS gid FROM users where userid = '%u'
+#   user_query = SELECT home, 501 AS uid, 501 AS gid FROM users WHERE userid = '%u'
+#
+#user_query = \
+#  SELECT home, uid, gid \
+#  FROM users WHERE username = '%n' AND domain = '%d'
+
+# If you wish to avoid two SQL lookups (passdb + userdb), you can use
+# userdb prefetch instead of userdb sql in dovecot.conf. In that case you'll
+# also have to return userdb fields in password_query prefixed with "userdb_"
+# string. For example:
+#password_query = \
+#  SELECT userid AS user, password, \
+#    home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \
+#  FROM users WHERE userid = '%u'
