+++ Notes
This describes modifications to IMP quota that can be configured to use one or two different devices (file systems). If using two devices, one is for INBOX and the other is for IMAP folders.
You can use one or two different devices (file systems) with quota enabled. This allows different quota values for INBOX and IMAP folders. Users use to keep messages on the INBOX. The bigger the quota, the bigger the INBOX file, with performance hit. In the other hand, messages are documents that must be filed, so you may want to give more space for IMAP folders than for the INBOX.
Uses system quota command.
Tested on Debian 5.0.5 (lenny), horde-3.3.8 and imp-h3-4.3.7.

You must modify the four files. Don't forget to change permission to each of them:
<code>
chown www-data command.php
</code>
Where www-data is the web user (Apache or equivalent).
You may need to give permission to your web user to execute quota:
<code>
chmod +s /usr/bin/quota
</code>

++++ command.php
* Function IMP_Quota_command accepts 2 new parameters:
> '**dev_inbx**' => User´s INBOX file system device - **REQUIRED**
> If you have INBOX and IMAP folders in the same device, use //ONLY// this parameter.
> If you have INBOX and IMAP folders in different devices and quota enabled on them you //MUST// use 'dev_fldrs' parameter also.
> Usually maps to /var/mail, /var/spool/mail.
> Examples: '/dev/hda6', '/dev/sdb2', '/dev/md2', '/dev/mapper/VOL1-VarM'.
> '**dev_fldrs**' => User´s home file system device - **OPTIONAL**
> Use only if you have INBOX and IMAP folders in different devices and quota enabled on them. \
Used for IMAP folders. Usually maps to /home.
> Examples: '/dev/hda7', '/dev/sda3', '/dev/md1', '/dev/mapper/VOL2-Home'.
> Obsolete parameters: grep_path, partition
* function getQuota:
> Function now takes care of exceeded quotas, quota not defined for that user and if it is using one or two devices (dev_inbx, dev_fldrs).
Backup your original imp/lib/Quota/command.php and create a new command.php with the following code:
<code type="php">
<?php
/**
* Implementation of the Quota API for IMAP servers with a unix quota command.
* This requires a modified "quota" command that allows the httpd server
* account to get quotas for other users. It also requires that your
* web server and imap server be the same server or at least have shared
* authentication and file servers (e.g. via NIS/NFS). And last, it (as
* written) requires the POSIX PHP extensions.
*
* You must configure this driver in horde/imp/config/servers.php. The
* driver supports the following parameters:
* 'quota_path' => Path to the quota binary - REQUIRED
* 'dev_inbx' => User´s INBOX file system device - REQUIRED
* If you have INBOX and IMAP folders in the same
* device, use ONLY this parameter.
* If you have INBOX and IMAP folders in different
* devices and quota enabled on them you MUST use
* 'dev_fldrs' parameter also.
* Usually: /, /var/mail, /var/spool/mail
* Examples: '/dev/hda6', '/dev/sdb2', '/dev/md2',
* '/dev/mapper/VOL1-VarM'
* 'dev_fldrs' => User´s home file system device - OPTIONAL
* Use only if you have INBOX and IMAP folders in
* different devices and quota enabled on them.
* For IMAP folders. Usually: /home
* Examples: '/dev/hda7', '/dev/sda3', '/dev/md1',
* '/dev/mapper/VOL2-Home'
