Debian Squeeze : Postfix VDA + MySQL + SASL + PostfixAdmin + Courier + Virtual Users Domains + Serveur de mail SMTP IMAP POP3 + Webmail

Je ne vais reprendre l'installation complète, car de nombreux tuto français ou anglais expliquent cela (chacun à sa manière et avec ses différences), mais voici quelques notes.

Notes

Postfix et quota

Par défaut Postfix n'inclus pas les quotas des utilisateurs, ils faut le patcher avec Posftix VDA, puis l'installer et le configurer (Available options and examples).

Description des fonctionnalités de "Posftix VDA" :

Brings per mailbox/maildir quota support to Postfix VDA
Support for Courier style maildir format, including maildirsize file
Limit either only INBOX or whole maildir
Customizable bounce message, used if mails are bounced (it's also an option)
Customisable suffix for Maildir support, sometimes needed for Courier IMAP
Enhanced patch delivery abilities using vfilter

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Debian Squeeze)

Install Postfix, Courier, Saslauthd, MySQL, phpMyAdmin

apt-get install postfix postfix-mysql postfix-doc mysql-client mysql-server courier-authdaemon courier-authlib-mysql courier-pop courier-pop-ssl courier-imap courier-imap-ssl libsasl2-2 libsasl2-modules libsasl2-modules-sql sasl2-bin libpam-mysql openssl phpmyadmin apache2 libapache2-mod-php5 php5 php5-mysql libpam-smbpass

Apply The Quota Patch To Postfix

# We have to get the Postfix sources, patch it with the quota patch, build new Postfix .deb packages and install those .deb packages:
apt-get build-dep postfix
cd /usr/src
apt-get source postfix
 
postconf -d | grep mail_version
# vérifiez la version (mail_version = 2.7.1)
 
# Patchin Postfix with VDA patch
wget http://vda.sourceforge.net/VDA/postfix-vda-2.7.1.patch
cd postfix-2.7.1
patch -p1 < ../postfix-vda-2.7.1.patch
dpkg-buildpackage
 
# Now we go one directory up, that's where the new .deb packages have been created:
cd ..
# Pick the postfix and postfix-mysql packages and install them like this: 
dpkg -i postfix_2.7.1-1_amd64.deb postfix-mysql_2.7.1-1_amd64.deb

Create The MySQL Database For Postfix/Courier

Utilisation de la configuration de PosftixAdmin

INSTALL.TXT

REQUIRED!!
----------
- You are using Postfix 2.0 or higher.
- You are using Apache 1.3.27 / Lighttpd 1.3.15 or higher.
- You are using PHP 5.1.2 or higher.
- You are using MySQL 3.23 or higher (5.x recommended) OR PostgreSQL 7.4 (or higher)


READ THIS FIRST!
----------------
When this is an upgrade from Postfix Admin 1.5.4 please read DOCUMENTS/UPGRADE.TXT!!

If you need to setup Postfix to be able to handle Virtual Domains and Virtual
Users check out :

http://high5.net/howto/
http://codepoets.co.uk/2009/postfix... (Debian+Courier+PostgreSQL+Postfix+Postfixadmin)
http://bliki.rimuhosting.com/space/... (Postfix+MySQL+Postfixadmin+Dovecot)
http://en.gentoo-wiki.com/wiki/Virt... (Postfix+MySQL+Postfixadmin+Courier) and Complete Virtual Mail Server

2. Setup a Database
-------------------

With your chosen/preferred database server (i.e. MySQL or PostgreSQL),
you need to create a new database. A good name for this could be :

  postfix

The mechanics of creating the database vary depending on which server
you are using. Most users will find using phpMyAdmin or phpPgAdmin the
easiest route.

If you wish to use the command line, you'll need to do something like :

For MySQL:
  CREATE DATABASE postfix;
  CREATE USER 'postfix'@'localhost' IDENTIFIED BY 'choose_a_password';
  GRANT ALL PRIVILEGES ON `postfix` . * TO 'postfix'@'localhost';


4. Check settings, and create Admin user
----------------------------------------

Hit http://yourserver.tld/postfixadmin/setup.php in a web browser.

You should see a list of 'OK' messages.

The setup.php script will attempt to create the database structure
(or upgrade it if you're coming from a previous version).

README.Debian

PostfixAdmin for Debian
=======================

After installing the package, you should find that :

http://youserver/postfixadmin/setup.php works. This should
guide you through the appropriate process.

You will need to create a database (either MySQL or PostgreSQL)
and know the username and password for it. The Database does not need
to be on the same server as the Postfixadmin install.



Recommended and Suggested Packages
==================================

 - Postfix
 - MySQL or PostgreSQL
 - Courier or Dovecot

Quota Exceedance Notifications

Visualiser le quota mail (imap) utilisé

Avec les Webmail (Roundcube, Squirrelmail, ...) en général c'est affiché si c'est configuré (avec au besoin le plugin quota).
Avec les clients lourds installés sur le poste client
1. Windows Live Mail ?.. je ne crois pas que cela soit possible... faut il la version pro ?..
2. Thunderbird : Add-ons : Display Quota

Alerter (l'administrateur et ou les utilisateurs) qui ont les boites mail qui saturent leur quota

quota.pl et quota_notify.pl (Author <jps@tntmax.com>)

Rajoutez ce script perl dans votre cron pour alerter l'admin des utilisateurs dont le quota dépasse un pourcentage. Et optionnellement alerter les utilisateurs que leur boite mail est bientôt pleine.

#!/usr/bin/perl -w
 
# Author <jps@tntmax.com>
#
# This script assumes that virtual_mailbox_base in defined
# in postfix's main.cf file. This directory is assumed to contain
# directories which themselves contain your virtual user's maildirs.
# For example:
#
# -----------/
#            |
#            |
#    home/vmail/domains/
#        |          |
#        |          |
#  example.com/  foo.com/
#                   |
#                   |
#           -----------------
#           |       |       |
#           |       |       |
#         user1/   user2/  user3/

Courier IMAP quota problem

La commande IMAP GETQUOTAROOT "INBOX" ne retourne pas le STORAGE attendu :

A001 GETQUOTAROOT "INBOX"
* QUOTAROOT "INBOX" "ROOT"
* QUOTA "ROOT"
A001 OK GETQUOTAROOT Ok.

au lieu de

A001 GETQUOTAROOT "INBOX"
* QUOTAROOT "INBOX" "ROOT"
* QUOTA "ROOT" (STORAGE 2046 2048)
A001 OK GETQUOTAROOT Ok.

N'oubliez pas de configurer le champ quota dans /etc/courier/authmysqlrc :

##NAME: MYSQL_QUOTA_FIELD:0
#
# Define MYSQL_QUOTA_FIELD to be the name of the field that can optionally
# specify a maildir quota.  See README.maildirquota for more information
#
MYSQL_QUOTA_FIELD       quota

De relancer les services courrier concernés :

/etc/init.d/courier-authdaemon restart

/etc/init.d/courier-imap restart

Et ensuite de vous envoyer un mail, qui aura pour conséquence de mettre à jour la valeur du quota utilisé par l'utilisateur dans le fichier "maildirsize" :

# cat /var/mail/virtual/mondomaine.fr/seb@mondomaine.fr/maildirsize
2097152S
     2076371           25
4608 1
6038 1
7537 1

Modification du quota de l'utilisateur alors que son fichier maildirsize indique un quota plein

Pour gérer le problème de maildirsize, le plus simple est de supprimer le fichier maildirsize (qui sera recréé lors de la prochaine réception de mail) de(s) l'utilisateur(s).

/var/mail/virtual# rm */*/maildirsize

##NAME: DEBUG_LOGIN:0
#
# Dump additional diagnostics to syslog
#
# DEBUG_LOGIN=0   - turn off debugging
# DEBUG_LOGIN=1   - turn on debugging
# DEBUG_LOGIN=2   - turn on debugging + log passwords too
#
# ** YES ** - DEBUG_LOGIN=2 places passwords into syslog.
#
# Note that most information is sent to syslog at level 'debug', so
# you may need to modify your /etc/syslog.conf to be able to see it.
