+## 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={{postfix.dovecot.quota.general}}
+  quota_rule2 = Trash:storage={{postfix.dovecot.quota.trash}}
+
+  # 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 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 /etc/dovecot/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 = 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:
+plugin {
+  #quota = dict:user::proxy::quota
+  #quota2 = dict:domain:%d:proxy::quota_domain
+  #quota_rule = *:storage=102400
+  #quota2_rule = *:storage=1048576
+}
