Postfix n'accepte pas l'adresse du destinataire : connexion à private/policy : Connexion refusée

Je me suis dit que j'allais être malin et ajouter amavis/spamassassin/clamav à mon installation Postfix qui fonctionne. J'ai réussi à la faire fonctionner, puis j'ai fait un changement. Je suis parti, j'ai bu une bière et j'ai découvert que j'avais fait une erreur. Voici ce qui se passe maintenant

J'ai cherché une réponse sur Google, il semble que "451 4.3.5" soit une erreur générique.

Voici le fichier master.cf ...

Postfix ne peut pas traiter le courrier parce que votre smtpd_recipient_restrictions la configuration indique de check_policy_service mais le service de politique référencé ne peut pas être interrogé. (probablement, parce qu'il n'est plus lancé).

smtpd_recipient_restrictions = ..., check_policy_service unix:private/policy, ...

Ce paramètre spécifie un chemin d'accès au socket UNIX relatif à l'adresse de l'utilisateur. chroot (c'est-à-dire /var/spool/postfix/private ), mais le nom ne précise pas de quoi il s'agit, pas plus que ne le fait votre master.cf contient une ligne qui ferait en sorte que postfix démarre un tel service de politique pour écouter sur ce socket.

Puisque votre postconf -M ne le mentionne pas vous avez peut-être supprimé une ligne par inadvertance dans votre master.cf qui était censé le démarrer. S'il a été démarré par d'autres moyens, il ne sera probablement pas placé dans la section private répertoire.

Avez-vous configuré d'autres filtres de courrier, comme la limitation du débit, le SPF ou les renvois temporaires ( "Greylisting" ) ? Si ma supposition est correcte et que cette était précédemment configuré dans votre master.cf Tout ce que vous avez à faire, c'est

  • supprimez les références aux services de stratégie des listes de restriction, si vous ne les utilisez pas, OU :
  • ajoutez les lignes dans master.cf qui définissent quel programme est réellement appelé lorsque le service de stratégie unix:private/policy est interrogé.

Vous pouvez trouver des informations utiles sur ce que était précédemment écouté sur ce socket UNIX en examinant la propriété des fichiers, ou en recherchant les journaux mentionnant private/policy mais antérieur à vos récents changements.
