This feature would be awesome if it’s integrated into the zammad GUI.
We’re currently doing it on the zammad server (debian) via systemd.
My description might be a bit outdated though since it was my first time working with systemd timers (was using cron for something like that 'til now).
Update: I just read it again - it’s definitely outdated but i can’t update it since the thread is closed.
It’s working like that but you can do it a lot smoother so it’s not a big deal.
