Port 25 accepts only configured domains and listed recipients, then forwards to an upstream; the outbound path is unchanged when the flag is off. Co-authored-by: Cursor <cursoragent@cursor.com>

# Alternative reverse-proxy: Caddy (spec 10.3) — the simplest option, fully
|
|
# automatic ACME with no separate certbot container. Caddy writes certificates
|
|
# as plain PEM under its own data directory, which this fragment bind-mounts
|
|
# to the host so SelfPost can read the same files.
|
|
#
|
|
# NOTE (spec 10.3 explicitly flags this): Caddy's on-disk cert path includes
|
|
# the ACME CA's name as a path segment, e.g.
|
|
# <data>/caddy/certificates/acme-v02.api.letsencrypt.org-directory/<hostname>/<hostname>.crt
|
|
# This has been stable across recent Caddy releases but is an internal
|
|
# storage detail, not a documented public API — VERIFY the exact path against
|
|
# the Caddy version you deploy (`docker compose exec caddy find /data/caddy/certificates -name '*.crt'`)
|
|
# before wiring it into the volume mount below.
|
|
#
|
|
# Merge with the base file — run this from the deploy/ directory (Compose
|
|
# resolves every relative path in both files against the directory of the
|
|
# FIRST -f file, i.e. deploy/, which is why paths below are ./caddy/...):
|
|
#
|
|
# docker compose -f docker-compose.yml -f caddy/docker-compose.caddy.yml up -d
