Add section 10.1 covering tag-triggered CI build, version from git tag flowing into both ldflags and the image tag (enforcing the 7.5.A restore invariant), and publishing to ghcr.io. Document Quay.io as an alternative registry. Update 11.7 (GitHub is no longer a dumb mirror) and add the workflow as deliverable 11.10. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
SelfPost
Self-hosted outbound SMTP relay with a web control panel, shipped as a single
Docker image. Postfix + OpenDKIM + a small Go panel run together under
supervisord; the panel manages multiple sending domains, per-domain DKIM keys
and SASL-authenticated applications bound to their domain.
SelfPost sends mail straight to the internet from your own IP, with DKIM signing, and is configured once through the panel. It is outbound only — it does not receive mail, provide mailboxes, or offer webmail.
Status: under active development. See docs/specification.md for the full requirements and docs/implementation-plan.md for the phased build plan.
Requirements (site prerequisites)
SelfPost assumes the host already provides the conditions for sending from your own IP — an unblocked outbound port 25, a static IP, configurable PTR/rDNS and a reasonable IP reputation. Providing these is the operator's job, not a feature of SelfPost. Detailed deployment docs land in a later phase.
