dovecot_quota:
plugins:
# 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:
- limits:
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
# 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 executed, 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.
- warnings:
quota_warning: storage=95%% quota-warning 95 %u
quota_warning2: storage=80%% quota-warning 80 %u
# 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
- backends:
# quota: dirsize:User quota
# quota: maildir:User quota
# quota: dict:User quota::proxy::quota
quota: fs:User quota
# Multiple quota roots are also possible, for example this gives each user
# their own 100MB quota and one shared 1GB quota within the domain:
- backends_extended2:
quota: dict:user::proxy::quota
quota2: dict:domain:%d:proxy::quota_domain
quota_rule: "*:storage=102400"
quota2_rule: "*:storage=1048576"
# 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.
