Using plugins
#############
**************************
Enable or disable a plugin
**************************
Modoboa provides an online panel to control plugins activation. You
will find it at *Modoboa > Extensions*.
To activate a plugin, check the corresponding box and click on the
*Apply* button.
To deactivate a plugin, uncheck the corresponding box and click on the
*Apply* button.
****************
Per-admin limits
****************
This plugin offers a way to define limits about how many objects
(aliases, mailboxes) a domain administrator can create.
It also brings a new administrative role: ``Reseller``. A reseller is a domain
administrator that can also manipulate domains and assign permissions
to domain administrators.
If you don't want to limit a particular object type, just set the
associated value to -1.
Default limits applied to new administrators can be changed through
the *Modoboa > Parameters > Limits* page.
.. _amavis_frontend:
********************
Amavisd-new frontend
********************
This plugin provides a simple management frontend for `amavisd-new
<http://www.amavis.org>`_. The supported features are:
* SQL quarantine management : available to administrators or users,
possibility to delete or release messages
* Per domain customization (using policies): specify how amavisd-new
will handle traffic
.. note::
The per-domain policies feature only works for new
installations. Currently, you can't use modoboa with an existing
database (ie. with data in ``users`` and ``policies`` tables).
.. note::
This plugin requires amavisd-new version **2.7.0** or higher. If
you're planning to use the :ref:`selfservice`, you'll need version
**2.8.0**.
Database
========
You must tell to Modoboa where it can find the amavis
database. Inside :file:`settings.py`, add a new connection to the
``DATABASES`` variable like this::
DATABASES = {
# Stuff before
#
"amavis": {
"ENGINE" : "<your value>",
"HOST" : "<your value>",
"NAME" : "<your value>",
"USER" : "<your value>",
"PASSWORD" : "<your value>"
}
}
Replace values between ``<>`` with yours.
.. note::
Modoboa doesn't create amavis tables. You need to install them
following the `official documentation
<http://www.amavis.org/#doc>`_.
Cleanup
-------
Storing quarantined messages to a database can quickly become a
perfomance killer. Modoboa provides a simple script to periodically
purge the quarantine database. To use it, add the following line
inside root's crontab::
0 0 * * * <modoboa_site>/manage.py qcleanup
Replace ``modoboa_site`` with the path of your Modoboa instance.
By default, messages older than 14 days are automatically purged. You
can modify this value by changing the ``MAX_MESSAGES_AGE`` parameter
in the online panel.
Release messages
================
To release messages, first take a look at `this page
<http://www.ijs.si/software/amavisd/amavisd-new-docs.html#quar-release>`_. It
explains how to configure amavisd-new to listen somewhere for the
AM.PDP protocol. This protocol is used to send requests.
Below is an example of a working configuration::
$interface_policy{'SOCK'} = 'AM.PDP-SOCK';
$interface_policy{'9998'} = 'AM.PDP-INET';
$policy_bank{'AM.PDP-SOCK'} = {
protocol => 'AM.PDP',
auth_required_release => 0,
};
$policy_bank{'AM.PDP-INET'} = {
protocol => 'AM.PDP',
inet_acl => [qw( 127.0.0.1 [::1] )],
};
Don't forget to update the ``inet_acl`` list if you plan to release from
the network.
Once amavisd-new is configured, just tell Modoboa where it can find
the *release server* by modifying the following parameters in the
online panel:
+--------------------+--------------------+------------------------+
|Name |Description |Default value |
+====================+====================+========================+
|Amavis connection |Mode used to access |unix |
|mode |the PDP server | |
+--------------------+--------------------+------------------------+
|PDP server address |PDP server address |localhost |
| |(if inet mode) | |
+--------------------+--------------------+------------------------+
|PDP server port |PDP server port (if | |
| |inet mode) 9998 | |
+--------------------+--------------------+------------------------+
|PDP server socket |Path to the PDP |/var/amavis/amavisd.sock|
| |server socket (if | |
| |unix mode) | |
+--------------------+--------------------+------------------------+
Deferred release
----------------
By default, simple users are not allowed to release messages
themselves. They are only allowed to send release requests to
administrators.
As administrators are not always available or logged into Modoboa, a
notification tool is available. It sends reminder e-mails to every
administrators or domain administrators. To use it, add the following
example line to root's crontab::
0 12 * * * <modoboa_site>/manage.py amnotify --baseurl='<modoboa_url>'
You are free to change the frequency.
.. note::
If you want to let users release their messages alone (not
recommended), go to the admin panel.
The following parameters are available to let you customize this
feature:
+--------------------+--------------------+------------------------+
|Name |Description |Default value |
+====================+====================+========================+
|Check requests |Interval between two|30 |
|interval |release requests | |
| |checks | |
+--------------------+--------------------+------------------------+
|Allow direct release|Allow users to |no |
| |directly release | |
| |their messages | |
+--------------------+--------------------+------------------------+
|Notifications sender|The e-mail address |notification@modoboa.org|
| |used to send | |
| |notitications | |
+--------------------+--------------------+------------------------+
.. _selfservice:
Self-service mode
=================
The *self-service* mode let users act on quarantined messages without
beeing authenticated. They can:
* View messages
* Remove messages
* Release messages (or send release requests)
To access a specific message, they only need the following information:
* Message's unique identifier
* Message's secret identifier
This information is controlled by *amavis*, which is in charge of
notifying users when new messages are put into quarantine. Each
notification (one per message) must embark a direct link containing
the required identifiers.
To activate this feature, go the administration panel and set the
**Enable self-service mode** parameter to yes.
The last step is to customize the notification messages amavis
sends. The most important is to embark a direct link. Take a look at
the `README.customize <http://amavis.org/README.customize.txt>`_ file to
learn what you're allowed to do.
Here is a link example::
http://<modoboa_url>/quarantine/%i/?rcpt=%R&secret_id=[:secret_id]
.. _stats:
********************
Graphical statistics
********************
This plugin collects various statistics about emails traffic on your
server. It parses a log file to collect information, store it into RRD
files (see `rrdtool <http://oss.oetiker.ch/rrdtool/>`_) and then
generates graphics in PNG format.
To use it, go to the online parameters panel and adapt the following
ones to your environnement:
+--------------------+--------------------+--------------------------+
|Name |Description |Default value |
+====================+====================+==========================+
|Path to the log file|Path to log file |/var/log/mail.log |
| |used to collect | |
| |statistics | |
+--------------------+--------------------+--------------------------+
|Directory to store |Path to directory |/tmp/modoboa |
|RRD files |where RRD files are | |
| |stored | |
+--------------------+--------------------+--------------------------+
|Directory to store |Path to directory |<modoboa_site>/media/stats|
|PNG files |where PNG files are | |
| |stored | |
+--------------------+--------------------+--------------------------+
Make sure the directory that will contain RRD files exists. If not,
create it before going further. For example (according to the previous
parameters)::
$ mkdir /tmp/modoboa
To finish, you need to collect information periodically in order to
feed the RRD files. Add the following line into root's crontab::
*/5 * * * * <modoboa_site>/manage.py logparser &> /dev/null
Replace ``<modoboa_site>`` with the path of your Modoboa instance.
Graphics will be automatically created after each parsing.
.. _postfix_ar:
***************************
Postifx auto-reply messages
***************************
This plugin let users define an auto-reply message (*vacation*). It is
based on Postfix capabilities.
The user that executes the autoreply script needs to access
:file:`settings.py`. You must apply proper permissions on this file. For
example, if :file:`settings.py` belongs to ``www-data:www-data``, you can add
the ``vmail`` user to the ``www-data`` group and set the read permission
for the group.
To make Postfix use this feature, you need to update your
configuration files as follows:
``/etc/postfix/main.cf``::
transport_maps = mysql:/etc/postfix/maps/sql-transport.cf
virtual_alias_maps = mysql:/etc/postfix/maps/sql-aliases.cf
mysql:/etc/postfix/mapfiles/sql-domain-aliases-mailboxes.cf,
mysql:/etc/postfix/mapfiles/sql-email2email.cf,
mysql:/etc/postfix/maps/sql-autoreplies.cf,
mysql:/etc/postfix/mapfiles/sql-catchall-aliases.cf
.. note::
The order used to define alias maps is important, please respect it
``/etc/postfix/master.cf``::
autoreply unix - n n - - pipe
flags= user=vmail:<group> argv=<modoboa_site>/manage.py autoreply $sender $mailbox
``<modoboa_site>`` is the path of your Modoboa instance.
Then, create the requested map files::
$ modoboa-admin.py postfix_maps mapfiles --categories autoreply
`mapfiles` is the directory where the files will be stored. Answer the
few questions and you're done.
.. note::
Auto-reply messages are just sent one time per sender for a
pre-defined time period. By default, this period is equal to 1 day
(86400s), you can adjust this value by modifying the **Automatic
reply timeout** parameter available in the online panel.
*************
Sieve filters
*************
This plugin let users create server-side message filters, using the
`sievelib module <http://pypi.python.org/pypi/sievelib>`_ (which
provides Sieve and ManageSieve clients).
Two working modes are available:
* A raw mode: you create filters using the Sieve language directly
(advanced users)
* An assisted mode: you create filters using an intuitive form
To use this plugin, your hosting setup must include a *ManageSieve*
server and your local delivery agent must understand the *Sieve*
language. Don't panic, Dovecot supports both :-) (refer to
:ref:`dovecot` to know how to enable those features).
.. note::
The sieve filters plugin requires that the :ref:`webmail` plugin is
activated and configured.
Go the online panel and modify the following parameters in order to
communicate with the *ManageSieve* server:
+--------------------+--------------------+--------------------+
|Name |Description |Default value |
+====================+====================+====================+
|Server address |Address of your |127.0.0.1 |
| |MANAGESIEVE server | |
+--------------------+--------------------+--------------------+
|Server port |Listening port of |4190 |
| |your MANAGESIEVE | |
| |server | |
+--------------------+--------------------+--------------------+
|Connect using |Use the STARTTLS |no |
|STARTTLS |extension | |
+--------------------+--------------------+--------------------+
|Authentication |Prefered |auto |
|mechanism |authentication | |
| |mechanism | |
+--------------------+--------------------+--------------------+
.. _webmail:
*******
Webmail
*******
Modoboa provides a simple webmail:
* Browse, read and compose messages, attachments are supported
* HTML messages are supported
* `CKeditor <http://ckeditor.com/>`_ integration
* Manipulate mailboxes (create, move, remove)
* Quota display
To use it, go to the online panel and modify the following parameters
to communicate with your *IMAP* server (under *IMAP settings*):
+--------------------+--------------------+--------------------+
|Name |Description |Default value |
+====================+====================+====================+
|Server address |Address of your IMAP|127.0.0.1 |
| |server | |
+--------------------+--------------------+--------------------+
|Use a secured |Use a secured |no |
|connection |connection to access| |
| |IMAP server | |
+--------------------+--------------------+--------------------+
|Server port |Listening port of |143 |
| |your IMAP server | |
+--------------------+--------------------+--------------------+
Do the same to communicate with your SMTP server (under *SMTP settings*):
+--------------------+--------------------+--------------------+
|Name |Description |Default value |
+====================+====================+====================+
|Server address |Address of your SMTP|127.0.0.1 |
| |server | |
+--------------------+--------------------+--------------------+
|Secured connection |Use a secured |None |
|mode |connection to access| |
| |SMTP server | |
+--------------------+--------------------+--------------------+
|Server port |Listening port of |25 |
| |your SMTP server | |
+--------------------+--------------------+--------------------+
|Authentication |Server needs |no |
|required |authentication | |
+--------------------+--------------------+--------------------+
.. note::
The size of each attachment sent with messages is limited. You can
change the default value by modifying the **Maximum attachment
size** parameter.
Using CKeditor
==============
Modoboa supports CKeditor to compose HTML messages. To use it, first
download it from `the official website <http://ckeditor.com/>`_, then
extract the tarball::
$ cd <modoboa_site_dir>
$ tar xzf /path/to/ckeditor/tarball.tag.gz -C sitestatic/js/
And you're done!
Now, each user has the possibility to choose between CKeditor and the
raw text editor to compose their messages. (see *User > Settings >
Preferences > Webmail*)
