I doubt this is a problem that will need a change in davmail. Container related issues are usually not fixed in user applications. What is the result of the following line in a LXC container? (lxc)$ systemd-run --property=DynamicUser=yes /usr/bin/true Are there any kernel messages (i.e. journalctl -t kernel) when the failure happens? We're looking for some permission denied stuff. My guess is that your lxc setup requires extra permissions for this to work. Thanks, Alex
