Configurer Postfix pour utiliser le LDA de Dovecot

Editer le fichier master.cf et ajouter :

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:mail argv=/usr/lib/dovecot/deliver -n -d ${recipient}

Le transport dovecot peut ensuite utiliser pour les boites virtuelles dans le fichier main.cf comme ceci :
```
dovecot_destination_recipient_limit = 1
virtual_transport = dovecot
```

On peut également utiliser transport_maps pour plus de souplesse et utiliser ainsi des backend LDAP / DB en retrounant de valeur comme dovecot:user@domain.

Configurer Postfix pour utiliser l'interface authentification de Dovecot pour du SASL

Dans la configuration de dovecot (dovecot.conf) :

  socket listen {
    master {
      # Master socket provides access to userdb information. It's typically
      # used to give Dovecot's local delivery agent access to userdb so it
      # can find mailbox locations.
      path = /var/run/dovecot/auth-master
      mode = 0600
      # Default user/group is the one who started dovecot-auth (root)
      user = vmail
      group = vmail
    }
    client {
      # The client socket is generally safe to export to everyone. Typical use
      # is to export it to your SMTP server so it can do SMTP AUTH lookups
      # using it.
      #path = /var/run/dovecot/auth-client
      path = /var/spool/postfix/private/auth
      mode = 0660
      user = postfix
      group = postfix
    }
  }

Dans la configuration de postfix (main.cf) :

# Authentification
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth

# Authentification seulement en ssl
smtpd_tls_auth_only = no
smtpd_tls_cert_file = /etc/dovecot/ssl/server.crt
smtpd_tls_key_file = /etc/dovecot/ssl/server.key
smtpd_use_tls = yes
