 ## 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 = mbox:~/mail:INBOX=/var/mail/%u
 mail_location = maildir:/var/vmail/%d/%n/Maildir

 # 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.
 namespace inbox {
  # Namespace type: private, shared or public
  #type = 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.
  #separator = 
  separator = .

  # Prefix required to access this namespace. This needs to be different for
  # all namespaces. For example "Public/".
  #prefix =

  #location =

  # There can be only one INBOX, and this setting defines which namespace
  # has it.
  inbox = yes

  # If namespace is hidden, it's not advertised to clients via NAMESPACE
  # extension. You'll most likely also want to set list=no. This is mostly
  # useful when converting from another server with different namespaces which
  # you want to deprecate but still keep working. For example you can create
  # hidden namespaces with prefixes "~/mail/", "~%u/mail/" and "mail/".
  #hidden = no

  # Show the mailboxes under this namespace with LIST command. This makes the
  # namespace visible for clients that don't support NAMESPACE extension.
  # "children" value lists child mailboxes, but hides the namespace prefix.
  #list = yes

  # namespace handles them (empty prefix should always have this as "yes")

 ## Mailbox handling optimizations
 ##

 # Mailbox list indexes can be used to optimize IMAP STATUS commands. They are
 # also required for IMAP NOTIFY extension to be enabled.
 #mailbox_list_index = no

 # The minimum number of mails in a mailbox before updates are done to cache
 # file. This allows optimizing Dovecot's behavior to do less disk writes at
 # the cost of more disk reads.
 #mail_cache_min_mail_count = 0

 # When IDLE command is running, mailbox is checked once in a while to see if
 # there are any new mails or other changes. This setting defines the minimum
 # time to wait between those checks. Dovecot can also use dnotify, inotify and
 # kqueue to find out immediately when changes occur.
 #mailbox_idle_check_interval = 30 secs

 # Save mails with CR+LF instead of plain LF. This makes sending those mails
 # take less CPU, especially with sendfile() syscall with Linux and FreeBSD.
 # But it also creates a bit more disk I/O which may just make it slower.
 # Also note that if other software reads the mboxes/maildirs, they may handle
 # the extra CRs wrong and cause problems.
 #mail_save_crlf = no

 # Max number of mails to keep open and prefetch to memory. This only works with
 # some mailbox formats and/or operating systems.
 #mail_prefetch_count = 0

 # How often to scan for stale temporary files and delete them (0 = never).
 # These should exist only after Dovecot dies in the middle of saving mails.
 #mail_temp_scan_interval = 1w

 ##
 ## Maildir-specific settings
 ##

 # By default LIST command returns all entries in maildir beginning with a dot.
 # Enabling this option makes Dovecot return only entries which are directories.
 # This is done by stat()ing each entry, so it causes more disk I/O.
 # (For systems setting struct dirent->d_type, this check is free and it's
 # done always regardless of this setting)
 #maildir_stat_dirs = no

 # When copying a message, do it with hard links whenever possible. This makes
 # the performance much better, and it's unlikely to have any side effects.
 #maildir_copy_with_hardlinks = yes

 # Assume Dovecot is the only MUA accessing Maildir: Scan cur/ directory only
 # when its mtime changes unexpectedly or when we can't find the mail otherwise.
 #maildir_very_dirty_syncs = no

 # If enabled, Dovecot doesn't use the S=<size> in the Maildir filenames for
 # getting the mail's physical size, except when recalculating Maildir++ quota.
 # This can be useful in systems where a lot of the Maildir filenames have a
 # broken size. The performance hit for enabling this is very small.
 #maildir_broken_filename_sizes = no

 # Always move mails from new/ directory to cur/, even when the \Recent flags
 # aren't being reset.
 #maildir_empty_new = no

 ##
 ## 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.
 #
 # The Debian value for mbox_write_locks differs from upstream Dovecot. It is
 # changed to be compliant with Debian Policy (section 11.6) for NFS safety.
 #       Dovecot: mbox_write_locks = dotlock fcntl
 #       Debian:  mbox_write_locks = fcntl dotlock
 #
 #mbox_read_locks = fcntl
 #mbox_write_locks = fcntl dotlock

 # Maximum time to wait for lock (all of them) before aborting.
 #mbox_lock_timeout = 5 mins

 # If dotlock exists but the mailbox isn't modified in any way, override the
 # lock file after this much time.
 #mbox_dotlock_change_timeout = 2 mins

 # 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

 # Like mbox_dirty_syncs, but don't do full syncs even with SELECT, EXAMINE,
 # EXPUNGE or CHECK commands. If this is set, mbox_dirty_syncs is ignored.
 #mbox_very_dirty_syncs = no

 # Delay writing mbox headers until doing a full write sync (EXPUNGE and CHECK
 # commands and when closing the mailbox). This is especially useful for POP3
 # where clients often delete all mails. The downside is that our changes
 # aren't immediately visible to other MUAs.
 #mbox_lazy_writes = yes

 # If mbox size is smaller than this (e.g. 100k), don't write index files.
 # If an index file already exists it's still read, just not updated.
 #mbox_min_index_size = 0

 # Mail header selection algorithm to use for MD5 POP3 UIDLs when
 # pop3_uidl_format=%m. For backwards compatibility we use apop3d inspired
 # algorithm, but it fails if the first Received: header isn't unique in all
 # mails. An alternative algorithm is "all" that selects all headers.
 #mbox_md5 = apop3d

 ##
 ## mdbox-specific settings
 ##

 # Maximum dbox file size until it's rotated.
 #mdbox_rotate_size = 2M

 # Maximum dbox file age until it's rotated. Typically in days. Day begins
 # from midnight, so 1d = today, 2d = yesterday, etc. 0 = check disabled.
 #mdbox_rotate_interval = 0

 # When creating new mdbox files, immediately preallocate their size to
 # mdbox_rotate_size. This setting currently works only in Linux with some
 # filesystems (ext4, xfs).
 #mdbox_preallocate_space = no

 ##
 ## Mail attachments
 ##

 # sdbox and mdbox support saving mail attachments to external files, which
 # also allows single instance storage for them. Other backends don't support
 # this for now.

 # Directory root where to store mail attachments. Disabled, if empty.
 #mail_attachment_dir =

 # Attachments smaller than this aren't saved externally. It's also possible to
 # write a plugin to disable saving specific attachments externally.
 #mail_attachment_min_size = 128k

 # Filesystem backend to use for saving attachments:
 #  posix : No SiS done by Dovecot (but this might help FS's own deduplication)
 #  sis posix : SiS with immediate byte-by-byte comparison during saving
 #  sis-queue posix : SiS with delayed comparison and deduplication
 #mail_attachment_fs = sis posix

 # Hash format to use in attachment filenames. You can add any text and
 # variables: %{md4}, %{md5}, %{sha1}, %{sha256}, %{sha512}, %{size}.
 # Variables can be truncated, e.g. %{sha256:80} returns only first 80 bits
 #mail_attachment_hash = %{sha1}

 #
 # 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
 # );

 # Database driver: mysql, pgsql, sqlite
 #driver = 

 # Database connection string. This is driver-specific setting.
 #
 # HA / round-robin load-balancing is supported by giving multiple host
 # settings, like: host=sql1.host.org host=sql2.host.org
 #
 # pgsql:
 #   For available options, see the PostgreSQL documention for the
 #   PQconnectdb function of libpq.
 #   Use maxconns=n (default 5) to change how many connections Dovecot can
 #   create to pgsql.
 #
 # mysql:
 #   Basic options emulate PostgreSQL option names:
 #     host, port, user, password, dbname
 #
 #   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
 #                              the default my.cnf location
 #     option_group           - Read options from the given group (default: client)
 # 
 #   You can connect to UNIX sockets by using host: host=/var/run/mysql.sock
 #   Note that currently you can't use spaces in parameters.
 #
 # sqlite:
 #   The path to the database file.
 #
 # Examples:
 #   connect = host=192.168.1.1 dbname=users
 #   connect = host=sql.example.com dbname=virtual user=virtual password=blarg
 #   connect = /etc/dovecot/authdb.sqlite
 #
 #connect =

 # Default password scheme.
 #
 # List of supported schemes is in
 # http://wiki2.dovecot.org/Authentication/PasswordSchemes
 #
 #default_pass_scheme = MD5

 # 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'

 # Query to get a list of all usernames.
 #iterate_query = SELECT username AS user FROM users
