Description

Hi,
So I found a similar issue in the repo, but the person closed it without any comment... #333

I recently moved my anonaddy docker deployment to another instance. Before restarting it I made sure to sudo chown -R 1000:1000 ./data.

I'm starting the container with docker-compose, I didn't change any user/group id.

  addy:
    image: anonaddy/anonaddy:latest
    container_name: addy
    depends_on:
      - db
      - redis
    ports:
      - "25:25/tcp"
      - "127.0.0.1:8484:8000/tcp"
    volumes:
      - "./data:/data:rw"
    env_file:
      - "./addy.env"
    environment:
      - "DB_HOST=db"
      - "DB_DATABASE=${MYSQL_DATABASE}"
      - "DB_USERNAME=${MYSQL_USER}"
      - "DB_PASSWORD=${MYSQL_PASSWORD}"
      - "REDIS_HOST=redis"
    restart: always

The service starts but outputs this error in loop:

Alright, so after checking a bit more it seems that the default user in the container is root (0) and not 1000.
I deleted the postfix folder and now it works.

But before we close the issue, I just want to make sure this is expected. It's written in the Readme that the default user is PUID: user id (default 1000) but I get this:

$ docker compose exec addy id   
uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel),11(floppy),20(dialout),26(tape),27(video)

Is that expected ?

Thanks !

Hi,
I have the same issue. I've delted /etc/postfix and /var/spool/postfix (separately and together) and the error logs still appear - even after a restart or recreating the container. Which folder did you delete exactly?

Perhaps as additional information: I've explicitly set PUID and PGID to 1000 in the env file.

[RobinFrcd]

I mount my volume with

    volumes:
      - "./data:/data:rw"

And I did a mv data/postfix data/postfix.bak

Thank you very much. Now it works for me again🥳
