README

A plugin that shows quota information with a pie chart for Roundcube.

Requirements

I only test this plugin with following environments. Other setup may work with luck.

Quota plugin is used in Roundcube to show used space and free space for given mailbox.

This plugin has been published on Packagist by the name of jfcherng-roundcube/quota.

Go to your ROUNDCUBE_HOME (i.e., the root directory of your Roundcube).
Run composer require jfcherng-roundcube/quota.
You may edit the config.inc.php under this plugin's directory if you want to do some configurations.

Create folder quota in ROUNDCUBE_HOME/plugins if it does not exist.
Copy all plugin files there.
Copy config.inc.php.dist to config.inc.php and edit config.inc.php if you want.
Edit ROUNDCUBE_HOME/conf/config.inc.php locate $config['plugins'] and add 'quota', there:

<?php

// some other codes...

$config['plugins'] = array(
    // some other plugins...
    'quota', // <-- add this
);

sudo vim /etc/dovecot/conf.d/90-quota.conf

  plugin {
    quota = maildir:User quota
    quota_rule = *storage=900M
    quota_rule2 = Trash:storage=+100M
    ...
  }

sudo service dovecot restart
