|
|
# 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:

#

# 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.
|
|
#
|
|
# REMEMBER: If you add any namespaces, the default namespace must be added
|

# session=yes makes Dovecot open and immediately close PAM session. Some

# PAM plugins need this to work, such as pam_mkhomedir.
|
|
#
|
|
# setcred=yes makes Dovecot establish PAM credentials if some PAM plugins

# need that. They aren't ever deleted though, so this isn't enabled by
|
|
# default.
|
|
#
|
|
# max_requests specifies how many PAM lookups to do in one process before

# recreating the process. The default is 100, because many PAM plugins

|
|
# cache_key can be used to enable authentication caching for PAM
|
|
# (auth_cache_size also needs to be set). It isn't enabled by default
|
|
# because PAM modules can do all kinds of checks besides checking password,
|
|
# such as checking IP address. Dovecot can't know about these checks
|
|
# without some help. cache_key is simply a list of variables (see
|
|
# doc/wiki/Variables.txt) which must match for the cached data to be used.
|
|
# Here are some examples:
|
|
# %u - Username must match. Probably sufficient for most uses.
|
|
# %u%r - Username and remote IP address must match.
|
|
# %u%s - Username and service (ie. IMAP, POP3) must match.
|
|
#
|

# The service name can contain variables, for example %Ls expands to
