postqueue -f é geralmente usado para liberar a fila, após a causa raiz da falha de entrega ser resolvida.

-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 pode ser usado para uma mensagem específica:

-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.

Se você tiver uma interrupção permanente de IPv6, poderá desabilitar o IPv6 no postfix com inet_protocols .

De link :

/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)
