+# Same stand as docker-compose.jambotron.yml, but from the ready image — nothing is built on the VM:
+# gitea.jambotron.com/jambotron_gang/reactive-mail-server (Drone builds it from master, see .drone.yml).
+# Pin a build: MAIL_IMAGE_TAG=<first 8 chars of the master commit>; default latest (pulled again on every deploy).
+# Test deploy on Jambotron (v0.2.3 75.3): pick this file in the deploy wizard.
+# Outside, only the web client + API (service "mail", port 8080) through Jambotron's Caddy — give it a domain.
+# SMTP (3025) stays inside the VM's docker network; nothing is sent outside (OUTBOUND_MODE=off).
+# Secrets are generated on the first start into the "secrets" volume — nothing to type in, nothing in git.
+# Mailboxes admin@<MAIL_DOMAINS> and trap@mail.test (catch-all): passwords in the "mail" log on the first start
+# (Jambotron: project → Services → mail → Logs) and in /app/data/initial-passwords.txt
+# of the "mail" container (docker exec <mail container> cat /app/data/initial-passwords.txt).
