# If you're in a hurry, see http://wiki.dovecot.org/QuickConfiguration

## 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

# 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. 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.
#
# 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.

## Dictionary server settings

# Currently this is only used by dict quota backend. The dictionary can be
# used either directly or though a dictionary server. The following dict block
# maps dictionary names to URIs when the server is used. These can then be
# referenced using URIs in format "proxy:<name>".

# Path to Berkeley DB's configuration file. See doc/dovecot-db-example.conf

## Plugin settings
##

plugin {
  # Here you can give some extra environment variables to mail processes.
  # This is mostly meant for passing parameters to plugins. %variable
  # expansion is done for all values.

# Quota plugin. Multiple backends are supported:
  #   dirsize: Find and sum all the files found from mail directory.
  #            Extremely SLOW with Maildir. It'll eat your CPU and disk I/O.
  #   dict: Keep quota stored in dictionary (eg. SQL)
  #   maildir: Maildir++ quota
  #   fs: Read-only support for filesystem quota
  #
  # Quota limits are set using "quota_rule" parameters, either in here or in
  # userdb. It's also possible to give mailbox-specific limits, for example:
  #   quota_rule = *:storage=1048576
  #   quota_rule2 = Trash:storage=102400
  # User has now 1GB quota, but when saving to Trash mailbox the user gets
  # additional 100MB.
  #
  # Multiple quota roots are also possible, for example:
  #   quota = dict:user::proxy::quota
  #   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.
  #   quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95
  #   quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80

quota_exceeded_message = "Mailbox is full / Blocks limit exceeded / Inode limit exceeded"

# 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:cache_secs=86400

# To let users LIST mailboxes shared by other users, Dovecot needs a
  # shared mailbox dictionary. For example:
  #acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes

# Convert plugin. If set, specifies the source storage path which is
  # converted to destination storage (mail_location) when the user logs in.
  # The existing mail directory is renamed to <dir>-converted.
  #convert_mail = mbox:%h/mail
  # Skip mailboxes which we can't open successfully instead of aborting.
  #convert_skip_broken_mailboxes = no
  # Skip directories beginning with '.'
  #convert_skip_dotdirs = no
  # If source storage has mailbox names with destination storage's hierarchy
  # separators, replace them with this character.
  #convert_alt_hierarchy_char = _

# 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
  #expire_dict = db:/var/lib/dovecot/expire.db

# 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).
  #lazy_expunge = .EXPUNGED/ .DELETED/ .DELETED/.EXPUNGED/
