[Postfixbuch-users] POSTFIX: Active-queue arbeitet nichts ab, warum?

[Rustedt, Florian]

Hallo zusammen,

Irgendwie "hängt" die active-queue bei uns?

Folgendes laut qshape:
./qshape.pl -l -b 10 -t 5 incoming
                                               T  5 10 15 20 25 30 35 40 45
45+
                                      TOTAL 1383 65 32 25 14 26 38 36 21 17

Aus irgendeinem Grund "versauern" die Emails in dieser Queue, obwohl die
Ziele allesamt bei diesen Domains nahezu vollständig lokal liegen
(imap/lmtp)?!

Wie man sieht, ist die active-queue-size auch nicht "bedroht", was laut der
Doku auf postfix.org als Ursache aufgelistet ist...

Hat jemand irgendeine Idee, warum mein Postfix sich weigert, die Emails zu
verarbeiten und diese dort liegen lässt??

Load und CPU-Last sind völlig im Rahmen, er idlet sogar etwas?!

Hier die Configs aus der main.cf:
