 Nous allons ajouter maintenant des utilisateurs virtuels, comptes qui ne sont pas des utilisateurs, **users** de la machine. Ces utilisateurs n'ont pas de compte Unix sur la machine, pas de shell, pas de répertoire personnel: ils n'existent que pour les composants du serveur de messagerie.

 Pour les systèmes de bases de données **sql**, il faudra fournir les données d'accès à la base de données dans des fichiers séparés.
 
-Nous allons utiliser **sqlite** car le nombre de comptes émail sera très réduit.
+Les adresses émail ainsi que les mots de passe seront stockés dans une base de données.

+![Notre base de données avec les utilisateurs virtuels](Images/dessin8.svg)
+
+Il est certainement possible d'ajouter la configuration des comptes mail virtuels à notre configuration actuelle. Après mûre réflexion, j'ai chois de procéder différemment: nous allons tester les différentes solutions de stockage à partir d'une installation propre de postfix/dovecot. Les solutions testées seront: *dbm*, *sqlite* et *postgresql* que nous avons déjà installée pour *gogs*. Les solutions à base de mysql sont très souvent déployées et sont donc documentées. Nous pourrons toujours rajouter cette dernière si le temps (et l'envie) le permet(tent).
+
+### Mise à blanc de nos configurations
+
+Nous avons mis plusieurs serviecs en route pour configurer notre serveur de mails; voici la liste des services à arrêter:
+
+* postfix
+* dovecot
+* dkim
+* dmarc
+* spf
+
+```shell
+root@atom:/home/ericadmin# service postfix stop
+root@atom:/home/ericadmin# service dovecot stop
+root@atom:/home/ericadmin# service opendkim stop
+root@atom:/home/ericadmin# service opendmarc stop
+root@atom:/home/ericadmin# service openspf stop
+Failed to stop openspf.service: Unit openspf.service not loaded.
+root@atom:/home/ericadmin#
+```
+Vérification des ports:
+
+```shell
+root@atom:/home/ericadmin# netstat -tlpn
+Connexions Internet actives (seulement serveurs)

+```
+
+Voilà, notre serveur de messagerie est arrêté ainsi que tous les services accessoires.
+
+### Sauvegarde de l'ancienne configuration
+
+Nous allons maintenant sauvegarder les répertoires contenant notre configuration actuelle. Nous laisserons les répertoires *opendmarc*, *opendkim*, *openspf* tels qu'ils sont; nous configurerons notre serveur d email sans les utiliser. Il vous sera toujours possible de vous réferer à leur installation/configuration dans la partie du tutoriel correspondante.
+
+```shell
+root@atom:/home/ericadmin# cd /etc
+root@atom:/etc# mv postfix postfix.user
+root@atom:/etc# mv dovecot/ dovecot.user
+root@atom:/etc# cd /var/lib
+root@atom:/var/lib# mv dovecot dovecot.user
+```
+
+### Suppression des paquets postfix et dovecot
+
+Nous allons maintenant procéder à la suppression des paquets dovecot et postfix:
+
+```shell
+root@atom:/etc# apt install exim4-daemon-light
+etc ....
+
+root@atom:/etc# dpkg -l | grep dovecot
+ii  dovecot-core                 1:2.2.27-3+deb9u3              i386         secure POP3/IMAP server - core files

+Traitement des actions différées (« triggers ») pour man-db (2.7.6.1-2) ...
+root@atom:/etc#
+```
+Voilà, les paquets sont supprimés (on a aussi purgé les fichiers de configuration, ce qui permet l'installation de nouveaux fichiers; on va les réinstaller et avoir une copie propre des fichiers de configuration.
+
+```shell
+root@atom:/etc# apt install postfix postfix-pgsql postfix-sqlite
+
+root@atom:/etc# dpkg -l | grep postfix
+ii  postfix                      3.1.9-0+deb9u2                 i386         High-performance mail transport agent
+ii  postfix-pgsql                3.1.9-0+deb9u2                 i386         PostgreSQL map support for Postfix

+root@atom:/etc#
+```
+Nous avons donc postfix d'installé avec les modules postgresql et sqlite.
+
+```shell
+root@atom:/etc# apt install dovecot-core dovecot-sqlite dovecot-pgsql dovecot-imapd

+ii  dovecot-imapd                1:2.2.27-3+deb9u3              i386         secure POP3/IMAP server - IMAP daemon

+root@atom:/etc#
+```
+Voilà, dovecot est ré-installé avec le support de sqlite et postgresql.
