Docker

While evaluation a new setup for a mail service including SMTP, IMAP, Web GUI, AntiSpam etc. someone kindly recommended mailcow-dockerized.

Recent versions of the Docker CLI support the prune option in different flavors to keep the system clean.

If your disk capacity is exceeded by Docker’s data folder (e.g. /var/lib/docker) it’s time to cleanup at least the images and this is much more comfortable than usage of filters and pipelines in the past.

But I also want to bring some risks into focus.
