## 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 =

mail_location = maildir:~/Maildir

mail_home = /var/vmail/%d/%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.

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 =

  # Prefix required to access this namespace. This needs to be different for

  # all namespaces. For example "Public/".

  #prefix =

  # Physical location of the mailbox. This is in same format as

  # mail_location, which is also the default for it.

  #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 its own subscriptions. If set to "no", the parent

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

  #subscriptions = yes

  # See 15-mailboxes.conf for definitions of special mailboxes.

  # expands to the logged in user's data. %%n, %%d, %%u and %%h expand to the

  # destination user's data.

## 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 = yes

# Trust mailbox list index to be up-to-date. This reduces disk I/O at the cost

# of potentially returning out-of-date results after e.g. server crashes.

# The results will be automatically fixed once the folders are opened.

#mailbox_list_index_very_dirty_syncs = yes

# Should INBOX be kept up-to-date in the mailbox list index? By default it's

# not, because most of the mailbox accesses will open INBOX anyway.

# 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 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.

}

##

## 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.

# 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.

#mbox_read_locks = fcntl

#mbox_write_locks = dotlock fcntl

mbox_write_locks = fcntl

# 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 = 10M

# Maximum dbox file age until it's rotated. Typically in days. Day begins

## Mail attachments

##

#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}

# Settings to control adding $HasAttachment or $HasNoAttachment keywords.

# By default, all MIME parts with Content-Disposition=attachment, or inlines

# with filename parameter are consired attachments.

#   add-flags-on-save - Add the keywords when saving new mails.

#   content-type=type or !type - Include/exclude content type. Excluding will

#     never consider the matched MIME part as attachment. Including will only

#     negate an exclusion (e.g. content-type=!foo/* content-type=foo/bar).

#   exclude-inlined - Exclude any Content-Disposition=inline MIME part.
