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.
