## Quota configuration.
##
# Note that you also have to enable quota plugin in mail_plugins setting.
# <doc/wiki/Quota.txt>
##
## Quota limits
##
# Quota limits are set using "quota_rule" parameters. To get per-user quota
# limits, you can set/override them by returning "quota_rule" extra field
# from userdb. It's also possible to give mailbox-specific limits, for example
# to give additional 100 MB when saving to Trash:
plugin {
#quota_rule = *:storage=1G
#quota_rule2 = Trash:storage=+100M
# LDA/LMTP allows saving the last mail to bring user from under quota to
# over quota, if the quota doesn't grow too high. Default is to allow as
# long as quota will stay under 10% above the limit. Also allowed e.g. 10M.
#quota_grace = 10%%
# Quota plugin can also limit the maximum accepted mail size.
#quota_max_mail_size = 100M
}
##
## Quota warnings
##
# 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.
# The commands are executed via script service by connecting to the named
# UNIX socket (quota-warning below).
# Note that % needs to be escaped as %%, otherwise "% " expands to empty.
plugin {
#quota_warning = storage=95%% quota-warning 95 %u
#quota_warning2 = storage=80%% quota-warning 80 %u
}
# Example quota-warning service. The unix listener's permissions should be
# set in a way that mail processes can connect to it. Below example assumes
# that mail processes run as vmail user. If you use mode=0666, all system users
# can generate quota warnings to anyone.
#service quota-warning {
# executable = script /usr/local/bin/quota-warning.sh
# user = dovecot
# unix_listener quota-warning {
# user = vmail
# }
#}
##
## Quota backends
##
# 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
plugin {
quota = maildir
quota_grace = 10%
quota_status_success = DUNNO
quota_status_nouser = DUNNO
quota_status_overquota = "522 5.2.2 Mailbox is full"
#quota = dirsize:User quota
#quota = maildir:User quota
#quota = dict:User quota::proxy::quota
#quota = fs:User quota
}
service quota-status {
executable = quota-status -p postfix
inet_listener {
port = 12340
}
}
# Multiple quota roots are also possible, for example this gives each user
# their own 100MB quota and one shared 1GB quota within the domain:
plugin {
#quota = dict:user::proxy::quota
#quota2 = dict:domain:%d:proxy::quota_domain
#quota_rule = *:storage=102400
#quota2_rule = *:storage=1048576
