(Diesmal zusätzlich mit meiner master.cf)
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?
