/!\ Vérifier les droits du fichier sympa.conf dans /etc/sympa, il doit être en sympa:sympa

Mysql
faire un mysql_secure_installation,
puis creer la bdd, user et appliquer les droits (dans l’exemple)

mysql -u root -p
CREATE DATABASE dbsympa COLLATE UTF8_general_ci;
CREATE USER usersympa identified by 'motdepasse';
GRANT ALL PRIVILEGES ON dbsympa.* to usersympa@localhost identified by 'motdepasse';

Modification du script d’init de sympa

# vim /etc/init.d/sympa

ajouter les lignes suivantes en haut du fichier après la ligne #!/bin/sh

Activer fastcgi et suexec

# a2enmod fastcgi
# a2enmod suexec

Redemarrer apache

# systemctl restart apache2

Création du vhost

Puis activer le vhost et reloader apache

# a2ensite sympa.conf
# systemctl reload apache2

Postfix

Modification du main.cf pour que sympa ajoute les alias dans /etc/mail/sympa_aliases

# vim /etc/postfix/main.cf

Modifier alias_maps comme ci dessous

alias_maps = hash:/etc/aliases,hash:/etc/mail/sympa_aliases

Modifier alias_database comme ci dessous

alias_database = hash:/etc/aliases,hash:/etc/mail/sympa_aliases

Modifier egalement la directive mydestination en ajoutant le domaine du serveur sympa

mydestination = $myhostname, srv-sympa.mondomaine.tld, srv-sympa, localhost.localdomain, localhost

Renseigner relayhost si Sympa dépend d’un autre serveur de messagerie

relayhost = [serveurmail.mondomaine.tld]:25

Vérifier vos reseaux autorisés

mynetworks = 127.0.0.0/8 192.168.3.0/24

Modifier ensuite le fichier master.cf :

# vim /etc/postfix/master.cf

Ajouter en fin de fichier

  sympa     unix  -       n       n       -       -       pipe
      flags=R user=sympa argv=/home/sympa/bin/queue ${recipient}
     
  sympabounce  unix  -       n       n       -       -       pipe
      flags=R user=sympa argv=/home/sympa/bin/bouncequeue ${recipient}

Puis redémarrer postfix

# systemctl restart postfix

Syslog

Configurer les traces

# vim /etc/rsyslog.conf

Ajouter a la fin de fichier

# Specifique a Sympa
local1.*       /var/log/sympa

Puis de redémarrer le serveur de log :

# systemctl restart rsyslog

..

Installation de sympa est terminé.
/!\ Penser a configurer le record A

voici un exemple chez mon registrar

@           A     189.xxx.xxx.xxx
srv-mail    A     189.xxx.xxx.xxx
srv-sympa   A     234.xxx.xxx.xxx
@           MX    srv-mail.mondomaine.tld. (10)

/!\ Penser a ouvrir le port 25 sur le FW

voici un petit aperçu de la partie exploitation.
Il faut cliquer sur première connexion pour pouvoir modifier l’adresse du listmaster et pour que d’autres utilisateurs puisses creer un compte et des listes après validation du listmaster.

Entrer le mail du listmaster ou un utilisateur qui désire utiliser le service (requis validation)

 

A réception créer le mdp et modifier le nom

Cliquer sur accueil pour voir les différentes options
Choisir création de liste

Définir un nom, objet, description et choisir le type de liste.

Après validation, il faut activer la liste

L’Administrateur validera les listes

Chercher une liste regroupe les listes créer par les utilisateurs autorisés

Il y a énormément de possibilités avec Sympa,

Voici une très bonne documentation quand a la mise en place de sympa
