Cette configuration fonctionnait mais après la mise à jour vers Dovecot 2 (Ubuntu 12.04) les mails vers mailman ne sont plus délivrés :
Au lieu de livrer à mailman, je reçois un rebond pour un utilisateur inexistant. mailinglist@my.host.tld

POSTFIX\_STYLE\_VIRTUAL\_DOMAINS = \['my.host.tld'\]Dovecot est configuré pour authentifier uniquement les utilisateurs via mysql - mais les alias de mailman sont identiques. Le domaine est un domaine virtuel postfix.
Des conseils pour savoir où chercher ? Que tester ? Cela fonctionnait avec la même configuration, mais maintenant j'utilise Dovecot-lda de Dovecot 2.0 et cela ne fonctionne plus, mais cela peut aussi être un autre problème, un changement de configuration.
