Adds the second F2 sub-project on top of the merged IMAP core: full
SEARCH criteria matching (flags, dates, size, headers, body/text,
NOT/OR), EXPUNGE (soft-delete via expunged_at), COPY, and MOVE (RFC
6851, advertised via CapMove/CapUIDPlus). Verified end-to-end with a
real go-imap/v2 client against embedded Postgres.

Merges the first F2 sub-project: a real :143 IMAP listener with Argon2id
auth, folder listing/selection, message FETCH (real ENVELOPE/BODY[] from
stored MIME), and flag STORE. Verified end-to-end with a real go-imap/v2
client against a message seeded through F1's SMTP path. See commit
9fa1929 for full details.
Adds a real :143 IMAP listener to the Go protocols service: a mailbox
owner authenticates over IMAP (Argon2id against mailboxes.password_hash,
enumeration-resistant per PLAN.md section 14.6), lists folders, selects
INBOX, fetches messages F1's SMTP path already persisted - including real
ENVELOPE/BODY[] built from the actual stored MIME bytes via go-imap/v2's
own ExtractEnvelope/ExtractBodySection helpers, not reconstructed from
denormalized columns - and sets/reads flags via STORE.
- ImapSessionUseCase orchestrates auth, folder listing/selection, message
querying, and flag mutation against new Postgres repositories (auth,
folders, message query, flags) and a local-disk blob reader.
- A github.com/emersion/go-imap/v2 (pinned v2.0.0-beta.8) Backend/Session
implements 7 real methods (Login, List, Select, Unselect, Status, Fetch,
Store) plus a correct no-op Poll; the other 10 of the interface's 18
methods (Create/Delete/Rename/Subscribe/Unsubscribe/Append/Idle/Expunge/
Search/Copy) are explicit stubs returning a clear "not yet implemented"
IMAP error - SEARCH/EXPUNGE/COPY/MOVE, IDLE/CONDSTORE, mailbox
management, and APPEND are separate follow-up sub-projects per the
design doc's agreed ordering with the user.
Verified end-to-end with a real go-imap/v2 imapclient (embedded Postgres,
no Docker needed) driving Login -> Select -> Fetch -> Store -> List
against a message seeded through F1's real SMTP use case, proving true
SMTP-write/IMAP-read interop, not just isolated unit tests.
Built via 8 sequential tasks under subagent-driven development, each
independently reviewed, plus a final whole-branch review. Two real bugs
were found and fixed before merge, both exactly the kind unit tests with
fakes cannot catch:
- Store's UID-set resolution silently no-op'd on dynamic ranges like
"UID STORE 1:*" (the common "mark all as read" operation) after an
earlier draft bypassed the folder's real message list; restored to
resolve against real messages via the same pattern Fetch already used
correctly, with tests proving both dynamic ranges and non-UID STORE.
- go-imap/v2's server calls Session.Poll() implicitly before the status
response of nearly every authenticated command (FETCH/STORE/SEARCH/
APPEND/COPY), not just IDLE as assumed - a hard-stubbed Poll broke every
real command through this path; fixed to a correct no-op.
- List had zero test coverage despite being committed scope; added unit
tests for wildcard/delimiter matching plus a real E2E LIST assertion.
Known follow-up, not blocking: a pre-existing test-fixture hygiene gap
(hardcoded content_sha256 blob hashes with no cleanup, shared across
several Postgres integration test files including one new to this
branch) causes local-dev test collisions on repeated runs against a
persistent database - invisible to CI (fresh Postgres per run) but worth
a cleanup pass.
Merges an independent validation pass on F0/F1: a real end-to-end test
(embedded Postgres, no Docker required) driving a live SMTP session
against the exact server main.go assembles, plus fixes for three gaps
the test's own analysis found - folder/mailbox counters not updated,
mailbox quota never checked at RCPT, and the aliases table never
consulted for recipient resolution. See commits 097fa37 and 2f73898
for full details.
Per feature/3-f0-f1-validation's own gap analysis (commit 097fa37):
- InboundMessageRepository.Persist now updates folders.unread_count,
folders.total_count, and mailboxes.used_bytes in the same transaction
as the message insert (PLAN.md section 6.1 "++counters" was a no-op
before this).
- MailboxRecord carries QuotaBytes/UsedBytes; ResolveRecipient rejects
RCPT with 452 4.2.2 when a target mailbox has already reached its
quota (used_bytes >= quota_bytes), before DATA - never silently
accepting mail into a full mailbox.
- MailboxRepository.ResolveDeliveryTargets tries a direct mailbox match
first, then falls back to the aliases table (exact source_address
match takes precedence over a domain catch-all). One RCPT TO can now
fan out to multiple mailboxes; alias destinations that don't resolve
to an internal active mailbox are silently skipped, since outbound/
external forwarding doesn't exist yet. postmaster@/abuse@/dmarc@-style
aliases now actually deliver.
The E2E test's counters_updated subtest flips from a documented KNOWN
GAP (t.Skipf) to a hard assertion now that it passes, and gains two new
subtests (quota_rejected_when_mailbox_full, alias_resolves_to_destination_mailbox)
covering the other two fixes end-to-end. New unit and Postgres
integration test coverage added for all three fixes at every layer.
Verified: full suite green on Windows (unit + E2E via embedded
Postgres, no Docker needed) and via WSL Docker against the real
docker-compose Postgres (all infrastructure/postgres and diskstorage
integration tests, not just E2E). lang-lint clean.
Boots a real Postgres (no Docker), applies the real migration and seed,
starts the real go-smtp server wired as main.go does, and drives a live
SMTP session. Asserts: 550 for unknown RCPT, durable EML + row with
uid_next allocation, sha256 disk/db match, outbox event, blob dedup with
ref_count. Documents the counters gap (PLAN 6.1) as an explicit skip.
Phase: F1 validation

Merges the first F1 sub-project: a real :25 SMTP listener for the Go
protocols service with STARTTLS, Postgres-backed recipient resolution,
content-hash-deduplicated blob storage, and transactional persistence.
See commit e501cdc for full details.
Adds a real :25 SMTP listener to the Go protocols service, giving F1's
"Nucleo SMTP" milestone its first working sub-project: application,
infrastructure, and presentation layers on top of F0's domain-only
Clean Architecture.
- ProcessInboundEmailUseCase resolves recipients against Postgres and
persists accepted mail (blob dedup by content hash, transactional
UID allocation + outbox event, never sending 250 OK before durable
commit per PLAN.md section 6.1).
- Postgres repositories via pgx/v5 (replacing lib/pq entirely).
- Local-disk blob storage with content-hash dedup, rename-before-commit
ordering so a DB row can never reference a file that isn't actually
on disk.
- A local-file TLS cert provider for STARTTLS, with an ephemeral
self-signed fallback so a missing/misconfigured cert degrades
gracefully instead of crash-looping the service (PLAN.md section 8.4).
- A github.com/emersion/go-smtp Backend/Session adapting real SMTP
traffic to the use case: unknown recipients get 550 5.1.1 before
DATA, duplicate RCPT TO for the same address is deduplicated, TLS is
hardened to the project's required PFS-only cipher/curve policy.
- A dev-seed script and Makefile target for local testing.
Explicitly out of scope (separate follow-up sub-projects): alias
resolution, SPF/DKIM/DMARC/ARC verification, Rspamd/ClamAV, Submission
ports with SASL auth, DKIM signing, outbound delivery, and the real
Traefik acme.json cert watcher.
Verified live end-to-end via WSL Docker: the full compose stack (db,
redis, migrate, auth, storage, protocols, web) reaches healthy, and a
real swaks SMTP session is accepted and durably persisted with correct
sequential UIDs, while an unknown recipient is correctly rejected with
550 5.1.1 and zero rows persisted. Built via 10 sequential tasks under
subagent-driven development, each independently reviewed, plus a final
whole-branch review that caught and fixed a TLS-crash bug, a blob
commit-ordering bug, missing TLS hardening, and missing CI integration
coverage before merge.
Known follow-up, not blocking: email_messages' partition only covers
July 2026 and needs a partition-management job before 2026-08-01.
Verified live via WSL Docker (docker compose up --wait): every other F0
service came up healthy, but web stayed unhealthy. Root cause was two
compounding issues, both invisible to static review:
1. Docker auto-sets HOSTNAME to the container ID; Next's standalone
server.js honors that env var and binds only to it instead of all
interfaces. Fixed by explicitly setting ENV HOSTNAME=0.0.0.0 in the
Dockerfile, after Docker's automatic assignment.
2. Even bound to 0.0.0.0 (IPv4), the healthcheck's `wget http://localhost`
resolved localhost to ::1 (IPv6) first inside the container, where
nothing was listening. Fixed by pointing the healthcheck at
127.0.0.1 explicitly instead of localhost.
Full stack (db, redis, migrate, auth, storage, protocols, web) now
reaches healthy end-to-end under docker compose up --wait.
Merges the F0 milestone from PLAN.md: monorepo scaffolding, initial Postgres
schema migration, the Go protocols domain layer with unit tests, health-checked
auth/storage/webmail service skeletons, local docker-compose.yaml, language
lint, and CI workflow.
Stands up the LambdaMail monorepo per PLAN.md's F0 milestone: local dev
scaffolding (.env.example, Makefile, .gitignore excluding PLAN.md/docs/
.superpowers/), the full initial Postgres schema as a golang-migrate
migration, the complete Go domain layer for services/protocols (value
objects, entities, domain events - zero external imports beyond
github.com/google/uuid) with unit tests, health-checked service skeletons
for auth/storage (TypeScript) and webmail (Next.js), a local
docker-compose.yaml wiring all services together, a language-enforcement
lint script, and a GitHub Actions CI workflow.
Built via 11 sequential tasks under subagent-driven development, each with
an independent implementer + reviewer cycle. Fixes applied during review:
DomainName.IsPunycode() added to satisfy the promised interface; ioredis
default-import typing under NodeNext; next.js bumped 15.0.3->15.5.21 to
resolve high/critical CVEs; lang-lint.mjs corrected to not flag its own
banned-terms list; web service healthcheck added so compose --wait
actually waits on it; webmail Dockerfile's missing public/ directory:
protocols go.mod version aligned with CI's Go 1.22 pin.
Known follow-ups for later phases (not blocking F0): go-arch-lint isn't
wired into CI yet; live docker compose up and migration apply have not
been exercised in this dev environment (no Docker/psql available here)
and will get their first real run in CI, which does have Docker.
