docker-mailserver: dovecot overrided files permission denied at server start

📝 Preliminary Checks

I tried searching for an existing issue and followed the debugging docs advice, but still need assistance.

👀 What Happened?

i start a simple docker postfix with dovecot files overrided but in the server, permission denied

and the status of overrided files

👟 Reproduction Steps

execute sudo docker-compose up and check the logs

with this compose file

version: '3'
services:
  mailserver:
    image: docker.io/mailserver/docker-mailserver:latest
    container_name: mailserver
    hostname: mail.xx.ae
    domainname: xx.ae
    ports:
      - "25:25"
      - "143:143"
      - "587:587"
      - "993:993"
    volumes:
      - /usr/local/docker/mailserver/mail-data/:/var/mail/
      - /usr/local/docker/mailserver/mail-state/:/var/mail-state/
      - /usr/local/docker/mailserver/mail-logs/:/var/log/mail/
      - /usr/local/docker/mailserver/config/:/tmp/docker-mailserver/
      - /etc/localtime:/etc/localtime:ro
      - ./docker-data/dms/config/dovecot/dovecot.conf:/etc/dovecot/dovecot.conf
      - ./docker-data/dms/config/dovecot/dovecot-dict-sql.conf.ext:/etc/dovecot/dovecot-dict-sql.conf.ext
      - ./docker-data/dms/config/dovecot/dovecot-sql.conf.ext:/etc/dovecot/dovecot-sql.conf.ext
      
    environment:
      - ENABLE_SPAMASSASSIN=1
      - SPAMASSASSIN_SPAM_TO_INBOX=1
      - ENABLE_CLAMAV=1
      - ENABLE_FAIL2BAN=1
      - ENABLE_POSTGREY=1
      - ENABLE_SASLAUTHD=0
      - ONE_DIR=1
      - DMS_DEBUG=0
      - PERMIT_DOCKER=host
    cap_add:
      - NET_ADMIN
      - SYS_PTRACE
    restart: always

I just want to reproduce locally a server running to test shared mail not working in production

Because of this, you have to run this before: sudo docker exec -it mailserver apt-get update

O after some instigation as you mentionned selinux cause issue so adding :Z make the trick

version: '3'
services:
  mailserver:
    image: ghcr.io/docker-mailserver/docker-mailserver:latest
    container_name: mailserver
    hostname: mail.equitativa.ae
    #env_file: mailserver.env
    ports:
      - "25:25"
      - "143:143"
      - "587:587"
      - "993:993"
      - "8082:8082"
    volumes:
      - ./docker-data/mail-data/:/var/mail/:Z
      - ./docker-data/mail-state/:/var/mail-state/:Z
      - ./docker-data/mail-logs/:/var/log/mail/:Z
      - ./docker-data/config/:/tmp/docker-mailserver/:Z
      - /etc/localtime:/etc/localtime:ro
      - ./docker-data/dms/config/dovecot/10-master.conf:/etc/dovecot/conf.d/10-master.conf:Z
    environment:
      - ENABLE_QUOTAS=0 
      - PERMIT_DOCKER=host
    cap_add:
      - NET_ADMIN
    restart: always

then for the apt-get we need to do apt-get update, then the install work, but some cmd are not existing, like ifconfig or netstat

so then this is the issue i have
