Hi,

bin recht neu mit Mailcow unterwegs, gefällt mir aber alles sehr gut bislang. Die Kuh läuft bei mir auch soweit einwandfrei, allerdings gab es sowohl beim neu aufsetzen als auch nach image-updates und anschliessendem docker-compose down && docker-compose up -d ein Problemchen mit Postfix. In den Logs von Postfix sind diverse warnings bzgl. Rechten, sprich div. files werden als non-root owned angemeckert:

Ergebnis dabei ist, dass ich keine Mails versenden kann. Ich habe mir jetzt damit beholfen, dass ich die angemeckerten files mittels chown root “angepasst” habe und aus der mailcow-ui heraus postfix neu starte. Damit tauchen keine neuen Fehlermeldungen in den logs mehr auf und ich kann normal mails versenden. Ich kann mir allerdings nicht vorstellen, dass das so gewollt ist.
Docker host ist ein Alpine-Linux, docker-compose führe ich als non-root-user aus.
