Comment envoyer un email bloqué dans ma file d'attente de courrier Postfix?

Comment puis-je envoyer cet email de Postfix? J'utilise la version 6.8 de CentOS sous Postfix 2.6.6.

Pouvez-vous essayer ping6 au lieu de ping? Il semble y avoir des problèmes avec votre connexion ipv6.

# ping6 alt1.aspmx.l.google.com connect: Network is unreachable. ifconfig: inet6 addr: fe80::8f1:cff:fe13:xxxxx/64 Scope:Link.

postqueue -f est généralement utilisé pour vider la file d'attente après la résolution de la cause première de l'échec de livraison.

-f     Flush the queue: attempt to deliver all queued mail.

       This option implements the traditional "sendmail -q" command, by
       contacting the Postfix qmgr(8) daemon.

       Warning: flushing undeliverable mail frequently will  result  in
       poor delivery performance of all other mail.

postqueue -i peut être utilisé pour un message spécifique:

-i queue_id
      Schedule  immediate delivery of deferred mail with the specified
      queue ID.

      This option implements the traditional sendmail -qI command,  by
      contacting the flush(8) server.

      This feature is available with Postfix version 2.4 and later.

Si vous avez une panne permanente d'IPv6, vous pouvez désactiver IPv6 dans postfix avec inet_protocols.

De http://www.postfix.org/IPV6_README.html :

/etc/postfix/main.cf:
    # You must stop/start Postfix after changing this parameter.
    inet_protocols = ipv4       (DEFAULT: enable IPv4 only)
    inet_protocols = all        (enable IPv4, and IPv6 if supported)
    inet_protocols = ipv4, ipv6 (enable both IPv4 and IPv6)
    inet_protocols = ipv6       (enable IPv6 only)

Merci, ça a marché! C'était réglé pour inet_protocols = all. Maintenant, il envoie:
