These unit files are meant to be used in the user session. You may drop them into `/etc/systemd/user` or `${XDG_DATA_HOME}/systemd/user` followed by `systemctl --user daemon-reload` to have systemd aware of the unit files.
These files are meant to be triggered either manually using `systemctl --user start offlineimap.service` or by enabling the timer unit using `systemctl --user enable offlineimap.timer`. Additionally, specific accounts may be triggered by using `offlineimap@myaccount.timer` or `offlineimap@myaccount.service`.
These unit files are installed as being enabled via a `mail.target` unit which is intended to be a catch-all for mail-related unit files. A simple `mail.target` file is also provided.
