I found out, my disk recently ran out of storage and needed to upgrade. Since Mailcow Dockerized is the only thing running on the server, I had checked it first.
Mailcow container uses over 9 GB of storage while my domains just got about 5. How comes it that the Mailcow service uses that much storage? Is there a safe way to cleanup without reset?
