#### Example Quadlet file
We have to use the .container extension for the quadlet generator to pick up the service.
Because dockermailserver uses multiple users inside the container, we will either have to use our own user as root, resulting in our e-mails being owned by a subuid. Alternatively, using UIDMap we can map our rootless user to UID 5000 in the container who owns our e-mails. Using UIDMap also maps root user 0 inside the container to an available sub-uid of our rootless user. Otherwise the container will not have permission to configure itself.

The example uses `Network=pasta` to use the pasta network driver, which will replace `slirp4netns`.
