Separate test/e2e Go module drives the shipped deploy/docker-compose.yml (plus a test-only override: self-signed cert, low ports, isolated compose project) against a fake DNS zone (CoreDNS) and an smtp-sink MX, exactly as an administrator and their applications would over HTTP/SMTP — covering the class of failure unit tests can't see (container wiring). Positive path: setup -> login -> domain -> DKIM record published into the fake zone -> application -> SMTP AUTH send -> DKIM verified against the DNS-published key -> send-log queued->sent. Negative: no-AUTH/unauthenticated relay, sender/login mismatch, L1 (anvil) and L2 (panel) rate limits, journal-milter fail-open, SELFPOST_HOSTNAME gate, session survives docker restart. release.yml moves off qemu to a native per-arch build (amd64/arm64), each gated by this suite before its tag is pushed and merged into the version manifest. Verified green on selfpost.example.com via `make e2e`; go vet/gofmt clean in both modules. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

# SMTP sink-MX for the e2e stand (plan C.4): accepts any mail on 25 and dumps

# each transaction to its own file under /mail, so the test harness can read

|
# the raw received message (headers + body, including the DKIM-Signature
|
|
# Postfix/OpenDKIM added) straight off disk. smtp-sink ships in the postfix
|
|
# package itself — no new dependency.
