getmail error: exec command deliver failed about docker-dovecot-getmail

[gw0]

This output Error: default config/data dir "/test_user/.getmail/" does not exist suggest you missed the /home part of the path.

The Docker command parameter -v /srv/mail/home:/home specifies which host/outside directory is mapped into the container as /home directory. Of course, the user in the container (which is not root) needs access to the directories outside for this to work. So, check the permissions and if uid/gid 1000:1000 has access.

The entrypoint.sh generates new users based on directories it finds in /home, but unfortunately does not take into account their existing uid/gid and just assigns new uid/gid numbers, for the first user this is 1000:1000. You are welcome to submit a PR to take uid/gid into account when creating these users (and maybe even check if they will have access).

okay i understand the workflow.
I managed to make getmail work correctly when setting permissions 1000:1000 to the volume mapped to /home.
Unfortunately i ran into similar problem when adding more users.

1. order of users. As uid/gid in the container are just counting up and list of users is in some order i dont't really understand (could be alphabetic?) ids inside and outside do not match. maybe this can solved by reading the uid:gid from the directorys using $(stat -c '%u' /path/to/folder):$(stat -c '%g' /path/to/folder) in the entrypoint.sh
2. As /home also gets permissions of a specific user, i can only run getmail for this user. this means another user cannot execute getmail cause of missing permisons for /home and the owner of home cannot execute getmail for another user cause of missing permissions for /home/<some_other_user>. It returns Error: default config/data dir "/home/some_other_user/.getmail/" does not exist.

I tried to set gid=100 inside and outside the container but it didn't work. Any suggestions.

Yes, exactly. Please clone the repository, make modifications, rebuild the Docker image locally, and when it works submit a PR with your changes.

As /home also gets permissions of a specific user...

The best approach (Docker creates it by default if the directory does not exist) would be for /home to be owned by root (uid:gid 0:0) and with world readable flags (chmod 755), like:

drwxr-xr-x 3 root root 4096 Feb 27  2017 home

With this everything should just work once the entrypoint.sh script is fixed to respect existing uid:gid.

It will be my first work with GitHub but I will give it a try. Send you an PR soon.
