Lorsqu'un courriel est envoyé à un domaine ou à un destinataire inexistant, je voudrais que l'expéditeur reçoive immédiatement un courriel de mailer-daemon l'informant que le destinataire n'existe pas.
En fait, ce qui se passe sur mon système, c'est que le courriel est placé dans la file d'attente différée et y reste le temps spécifié dans la configuration. Comme je l'ai configuré delay_warning_time = 30m après 30 minutes dans la file d'attente, l'expéditeur reçoit une notification mais ce n'est pas ce que je veux pour les adresses non existantes. Ce que je veux, c'est rejeter l'email immédiatement et notifier l'expéditeur.
Quelqu'un sait-il ce que je fais mal ? Merci beaucoup.
Actuellement, les courriels des destinataires non existants se trouvent dans la file d'attente de Postfix :
