Hallo Ralf!

Vielen Dank für deine kompetente Antwort. Das Problem hat sich mittlerweile auch wieder gelegt und alle mails waren plötzlich draussen.

Allerdings liegen einige mail sehr lange in der queue, bis diese dann endlich rausgehen.

Könntest du meine Postfix Konfiguration prüfen, ob dir was negatives auffällt?
Was hälst du von der Art, wie Amavisd eingebunden wird.  (Im Tutorial von https://dokuwiki.nausch.org/doku.php/centos:mail_c7:start ist ja beschrieben, dass bei smtpd mittels amavisd_milter und bei submissionport mittels content_filter=smtp:[127.0.0.1]:10024 gearbeitet wird)

1.) Würdest du das anders machen?

2. ) Was kann ich verbessern?

Hallo liebe Postfixler!

Ich bin am verzweifeln, bitte um rasche Hilfe!

Wie ich heute schon unter einem anderen Mailaccount geschrieben haben 
wir seit unserer Umstellung auf einen neuen postfix Probleme mit der Mailq.

Es gibt ungefähr 20 mails die in der Mailq hängen und bei jedem erneutem 
Ausliefern z. B. mit postsuper -r ALL eine andere QUEUEID bekommen uns 
wieder hängenbleiben.

Naja, es ändert sich ja nix, warum sollten die nach einem "postsuper -r ALL" auch rausgehen...
 

... und landet mit **C39423087F6584 wieder in der mailq

und in der "mailq" Ausgabe steht der Grund dran, warum nix passiert..

Beispiel:
3tTspy5cRWz5vMx     385271 Thu Dec  1 09:45:46 absender@domain.de.example
                (connect to 943rs2.de[54.93.180.215]:25: Connection timed out)
                                               empfaenger@943rs2.de
                (connect to meinberlin.net[193.203.122.97]:25: Connection timed out)
                                               empfaenger@meinberlin.net
