The message endpoint used implicit TLS and the PDF endpoint STARTTLS on the same port, so one of them always failed. Both now share one connection path with an explicit SMTP_RELAY_SECURITY, log in only with credentials, and take SMTP_FROM and SMTP_REPLY_TO. /health answers 503 when the SMTP server refuses, so the container turns unhealthy instead of looking fine. The old tests never ran; eight new ones do, in CI too.
libreshop/mail
Python microservice for transactional shop mail.
Part of the libreshop toolkit. Image
published at git.librete.ch/libreshop/mail on every push to main
and on v* tags.
Source
This repo was extracted from mp/mail/ on 2026-04-29; mp was the
first concrete adapter consuming the toolkit. mp's compose.yml now
pulls git.librete.ch/libreshop/mail:<pin> instead of building locally.
Build locally
docker build -t libreshop/mail:dev .

Adapter contract
See docker-entrypoint.sh and Dockerfile for the runtime surface.
Adapters configure the component via env vars and bind-mounted volumes;
do not patch the running container or rely on internal paths.
