Description

Got a VM running with: Rocky Linux, VERSION="8.6 (Green Obsidian)"
podman version 4.0.2, podman-composer version 0.1.7dev
Went for podmans rootless mode: https://docker-mailserver.github.io/docker-mailserver/edge/config/advanced/podman/#installation-in-rootless-mode

Prepared the VM with the following commands:

mkdir -p /srv/docker-mailserver/{mail-data,mail-state,mail-logs,config}
restorecon -vv -F -r /
systemctl enable --now --user podman.socket
curl -LO https://raw.github.com/docker-mailserver/docker-mailserver/v11.0.0/docker-compose.yml

I had a few denials, so I put SELinux into permissive mode: setenforce 0.
