Implements the secure single-admin panel entry (spec 7.6). - internal/store: modernc.org/sqlite (pure Go, static build), WAL + foreign keys, embedded PRAGMA user_version migrations; schema 0001 covers admin/settings/domains/applications/send_log/rate_limits (spec 9). - Setup secret-link (spec 7.6.1): 128-bit crypto/rand token, printed to log + /data/setup-token (0600), 10-min TTL with regeneration, per-IP rate limit, subtle.ConstantTimeCompare, failures don't invalidate, one-time admin form, permanent invalidation once admin exists (/setup 404). - bcrypt admin password; server-side username/password validation. - Login + in-memory sessions, crypto-random token, cookie HttpOnly/Secure/SameSite (Secure toggleable for dev HTTP), login rate limit, auth middleware. - html/template base layout + setup/login/dashboard, vendored htmx 2.0.4. - build/entrypoint.sh: fix bind-mounted /data ownership as root before supervisord drops to the unprivileged panel user (found via container test). Verified on selfpost.mixfed.ru: go vet/build/test/gofmt clean; e2e curl of setup+login flows; docker build + run with -v ./data:/data creates the DB and 0600 token owned by panel.

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.
