mailgoserver/docker-deploy/docker-compose.yml

# Three independent setups, selected with --profile so they don't both start by accident:
#
#   docker compose --profile standalone up -d --build     # mailserver only
#   docker compose --profile with-rspamd up -d --build    # mailserver + rspamd, same container
#   docker compose --profile all-in-one up -d --build      # mailserver + rspamd + redis (Bayes/greylisting)
#
# Every profile mounts exactly one volume — server_data/ — since every persistent thing
# any of these processes own (mailgoserver's own data, rspamd's dbdir, redis's RDB
# snapshot) lives under that single directory now; see the Dockerfiles' comments.
#
# All three default to the standard mail ports on the host (25/465/143/993) — the app
# itself binds those directly (via a Linux file capability, not by running as root — see
# the Dockerfiles), no port remapping needed — plus port 80 (only actually used while
# Let's Encrypt HTTP-01 is enabled, see internal/webui's Let's Encrypt page) and the
# app's own non-privileged web ports (5000/5001; put a reverse proxy or your own 80/443
# mapping in front of those if you want the dashboard on standard web ports too — note
# port 80 is already claimed here for HTTP-01 if you enable it). Only run one profile at
# a time unless you've overridden the host ports for it (see .env.example) — they'd
# otherwise all try to bind the same host ports.
