From 833dc76c2ebc4c93d9f8402c09bf7e9e5aef7c58 Mon Sep 17 00:00:00 2001 From: Lucas Rayan Date: Sun, 2 Aug 2026 09:33:29 -0300 Subject: [PATCH 01/15] #21: make the auth service actually authenticate The F4 auth service issued a valid session for any email and any password, and accepted any non-empty string as a second factor. Reproduced against the router before touching it: an invented password plus the code "000000" returned a SUPER_ADMIN token that opened /api/v1/admin/dashboard. Passwords. Hashing moves from PBKDF2 to Argon2id via hash-wasm, which is what PLAN.md section 9 and the Go service already use - the previous scheme meant a password set through the mail stack could never verify here. Interoperability was checked in both directions before adopting the library: a hash written by alexedwards/argon2id verifies in Node and one written here verifies in Go. hash-wasm is pure WASM, so the multi-arch Alpine images need no native build. verifyPassword no longer falls back to comparing the password against the stored hash. That fallback turned every stored hash into a working credential: anyone with a database dump could authenticate by sending the hash back. Anything that is not an argon2id PHC string is now refused. Logins are decided against the database, with the failure counter and the temporary lockout of PLAN.md section 5.2. An unknown address and a wrong password give the same answer, and the unknown case still pays for a hash so response time does not enumerate valid addresses. Second factor. The TOTP secret is generated server-side, stored encrypted and never accepted back from the client - the confirm step used to take whichever secret the caller sent, so anyone could confirm with their own. Recovery codes are Argon2id, single-use, and consumed under a guard so two concurrent requests cannot spend the same one. App passwords are issued and revoked through real endpoints instead of browser state. Sessions gain a "purpose" claim. Without it the challenge token - handed out after the password but before the second factor - satisfied every check a real session did, which skipped MFA entirely. The dev seed carried a hand-written password_hash whose digest was 24 bytes instead of 32, so it matched no password at all. Nothing noticed while passwords went unverified; it is a real hash now. Verified with 30 tests, 13 of them against a real Postgres: wrong password, unknown account, pass-the-hash, wrong TOTP code, challenge token replay, lockout, single-use recovery codes, and the surface isolation that F4's acceptance criteria require.

There was no middleware and no guard in the layout, so /admin/dashboard returned 200 unauthenticated - only its data calls failed. middleware.ts now redirects both surfaces to their login when the session cookie is missing, expired, carries the wrong audience, or is a pre-MFA challenge token. It reads the claims without verifying the signature on purpose: the signing key belongs to the auth service and must not reach the browser bundle. That is sound because this is not the boundary - every /api/v1 request is verified for real upstream. Nothing served /api/v1/*. next.config.ts had no rewrites and there were no route handlers, so every call the pages made 404'd against the Next server, while AUTH_SERVICE_URL sat unused. A catch-all route now proxies to the auth service, forwarding the client address and preserving multiple Set-Cookie headers, which logout needs to clear both surfaces. Session cookies also move to Path=/, since a cookie pinned to /user or /admin was never sent with the /api/v1 requests that needed it. i18n existed only as files. The three bundles had perfect key parity and real translations, but no library, no imports and no switcher: the UI was hardcoded English and i18n.test.ts compared keys while the feature was absent. There is now a provider, a hook, a language switcher, and server-side Accept-Language negotiation that honours q-values and matches a bare "pt" to pt-BR. Logins, both layouts and the settings screen consume it; the admin pages still have English titles. The settings screen invented app passwords in the browser with Math.random and never stored them. It now calls the API, which returns the password once and keeps only its hash.

The security regressions this branch adds - wrong password, pass-the-hash, wrong TOTP code, lockout, single-use recovery codes - are all decided in the database, so without one they skip silently and CI would go green on an unauthenticated server. webmail-build only ran "npm run build", so i18n.test.ts never executed anywhere. It now lints and tests too, and the package gained the lint script it was missing. *.tsbuildinfo is ignored: tsc --noEmit leaves it behind and it is a local build cache, not source.

The subject, snippet, sender name and message-id columns have existed since the first migration, but nothing ever wrote them: every row went in with those fields NULL. A message list built on the database would have shown blank subjects for every message. Delivery now parses them once per message and stores them, decoding RFC 2047 encoded words so an accented subject is readable rather than raw. Parsing failures are non-fatal: a message with unreadable headers is still delivered, just with less metadata, because refusing it would lose mail over a malformed Subject. Worse, a message the spam filter routed to Junk failed delivery outright when the mailbox had no Junk folder - the sender got 451 and retried forever against a mailbox that would never grow one on its own. Delivery now falls back to INBOX and says so in the log. Found by sending a real message through port 25 against the running stack. The SMTP handler also swallowed the cause of any unexpected failure: the peer saw "temporary error" and the operator got nothing. It is logged now, which is how the missing folder was diagnosed at all. Also adds the JWT verifier the mail API needs. The tokens are minted by the auth service and verified here under the same secret, so the test fixtures are real tokens produced by that service: if the two implementations drift, this fails before the webmail does. Challenge tokens, wrong secrets, tampered payloads, expired tokens and the other surface's audience are all rejected. The dev seed gained the standard folder set, which is what a provisioned mailbox has and what the fallback above should not have to compensate for.

The API lands here instead, because the folder, UID, MODSEQ, flag and blob logic already exists and is tested in this service for IMAP. Reimplementing it in TypeScript would mean two implementations of the same semantics and two chances to disagree about what a UID means. Reads use a projected read model rather than hydrated aggregates, which is the CQRS exception PLAN.md section 2 carves out for webmail queries. Every query is scoped to the mailbox resolved from the verified session, never to an identifier taken from the request, so one account cannot read another's mail by guessing a UID - covered by a test that tries exactly that and expects 404. Sending reuses ProcessOutboundEmailUseCase, so mail written in the browser gets the same treatment as mail submitted over 587: send limits, DKIM signing, and the durable queue. The From address comes from the session and never from the request body; letting the body choose it is how a webmail becomes a relay for spoofed mail. MIME is parsed server-side because this service already depends on a MIME library. A message that will not parse still returns its raw text - an unreadable message beats an inbox that refuses to open one. Marking a message read updates the flag and the folder counter in one transaction, and only on a real transition, so re-opening a message cannot drive unread_count negative. Verified against the running stack: a message delivered over port 25 appears in the list with its decoded subject and sender, opens, marks itself read, is found by search, and a message composed in the webmail reaches outbound_jobs with the session's address as the envelope sender.

Both now use the API, including search, the unread badges in the sidebar (which were the literals "3" and "1", so an empty inbox still advertised unread mail), and marking a message read on open. The undo window now means what it says: the message is held in the browser and only submitted when the countdown elapses, so cancelling it means nothing was ever queued rather than trying to recall it afterwards. Message bodies render in an iframe with an empty sandbox - no scripts, no same-origin - and remote references are stripped until the reader asks for images, so a tracking pixel cannot fire on open. The previous sandbox allowed popups. The admin page titles and the language switcher labels now come from the bundles. The labels live there rather than in the source because PLAN.md R9 keeps non-ASCII out of code, and each language should be named the way that language names it. ADR-001 assigned the mail API to the TypeScript storage service; the reasoning for putting it in Go instead is recorded in PLAN.md, which .gitignore deliberately keeps out of the repository, so that revision lives only in the working copy.

It retired the live key and inserted a placeholder as ACTIVE - private_key_enc was the literal string "dummy-encrypted-key" - so FindActiveKeys then failed for the whole domain and outbound mail stopped being signed, with the real key already gone. Reproduced against a database before changing anything. The root cause runs deeper: the auth service derives its encryption key with a plain SHA-256 of the master key while the protocols service uses HKDF with its own info string, so nothing the auth service seals can ever be opened by the signer. Rotation therefore moves to the protocols service, which owns that vault and the real key generator. It retires the previous key with a seven-day overlap in the same transaction rather than deleting it, because mail already sent under it is still being verified. Domain onboarding had three defects in one function. It built the alias destination by interpolating the domain name into the SQL text, which was injectable; it reused one placeholder for a CITEXT and a VARCHAR column, which made the statement fail and happened to hide the injection; and it ignored its scope argument entirely, so any DOMAIN_ADMIN could create domains. It also provisioned postmaster, abuse and security, missing the dmarc and tlsrpt aliases that the published records point at - PLAN.md section 7.4b is explicit that reports bounce without them. The TLS panel returned fixed values: acme_status "VALID" and 72 days to expiry, whatever the process actually held. It now reads the certificate watcher, and a compile-time assertion keeps the wiring from silently regressing into "disabled". The audit log and the readiness scorecard were fixtures too, and their field names did not match the API they now read. Two tests failed and a third asserted a fabricated constant: one depended on test order through a shared fixture that had a second factor enrolled, one used a fixed domain name and so passed once per database, and one expected "records: 13" from a function that never touches DNS. All three are fixed, and the suite now passes twice in a row against one database.

A missing JWT_SECRET fell back to a constant that is published in this repository, so any deployment that forgot the variable would have accepted session tokens anyone could mint, including an admin one. The auth service now refuses to start without a secret of at least 32 characters. The test suites set it through vitest config, because ESM hoists imports and an assignment inside a test file runs too late. Session cookies were issued without the Secure attribute: it is driven by NODE_ENV, which compose never set. Behind a TLS terminator that is a downgrade waiting to happen. Nothing created the first mailbox. A fresh install has no domain and no account, and every route into the console needs one - so there was no first login. There is now a create-admin command, which also provisions the standard folders and the four system aliases. It is a deliberate command rather than a bootstrap on boot: creating an administrator as a side effect of starting a container is how a deleted account quietly comes back. Also: the production images were shipping compiled test files, since the build compiled everything under src. A separate build config excludes them while lint still type-checks them. Documentation. README.md covers what this is, how it is put together, and what is not finished - stated plainly, because a mail server that half works loses mail. docs/DEPLOYMENT.md is the Coolify path in the order it has to happen, starting with the three prerequisites no code can satisfy: outbound port 25, the PTR record, and the DNSSEC delegation. docs/OPERATIONS.md is the runbook - health states, certificates, backups, reading a delivery failure, DKIM rotation, and an explicit list of what is not automated. .env.production.example replaces guessing which of the dev defaults are safe: none of them are. docs/ was gitignored as a place for internal notes; only docs/internal/ is now, so these guides ship with the code.

Open a support ticket asking for outbound SMTP +to be unblocked, and say what the host is for. + +If the answer is no, LambdaMail can still send through a relay: set `RELAY_HOST` +and friends, and the relay is added to the published SPF record automatically. +Receiving is unaffected either way. + +### 2. Reverse DNS (PTR) + +The PTR for your public IPv4 must resolve to `PRIMARY_MAIL_HOST`, and that name +must resolve back to the same address. This is called FCrDNS, and Gmail and +Outlook will refuse or spam-folder mail without it. + +**The PTR is set by whoever owns the IP block — your VPS provider, not +Cloudflare.** It is usually a field in the server's control panel. + +```bash +dig -x 203.0.113.10 +short # must print mail.example.com. +dig mail.example.com +short # must print 203.0.113.10 +``` + +### 3. DNSSEC — only if you want DANE + +Signing the zone is a prerequisite for DANE. It is enabled in the Cloudflare +dashboard and needs a DS record published at your registrar, which is manual. + +Skip this for a first deployment. DANE stays off under `TLS_MODE=traefik` +anyway, and turning it on without understanding the rollover is the single most +effective way to make every validating MTA reject your mail permanently. + +### IPv6 + +Either configure it properly — AAAA record, matching PTR, and covered by SPF — +or leave `PUBLIC_IPV6` empty. Half-configured IPv6 is a common cause of +rejection, and empty is a safe answer. + +--- + +## Step 1 — Point DNS at the host + +Two records must exist before the first deploy, because Coolify's proxy needs +them to obtain certificates: + +| Type | Name | Value | +| :--- | :--- | :--- | +| `A` | `mail` | your public IPv4, **DNS only, not proxied** | +| `A`/`CNAME` | `mta-sts` | the same host (may be proxied) | + +The `mail` record must not be behind Cloudflare's proxy. SMTP is not HTTP; +proxying it breaks the mail ports and hides your real address from the +certificate challenge. + +The rest of the 13 records are created by the service once you give it a +Cloudflare token, or you can add them by hand later. + +## Step 2 — Create the application in Coolify + +1. **New Resource → Docker Compose**, pointed at this repository. +2. Coolify will read `docker-compose.yaml`. Leave the compose file alone; all + configuration is environment. +3. Under **Environment Variables**, paste the contents of + `.env.production.example` and replace every value marked `CHANGE`. + +Generate each secret separately: + +```bash +openssl rand -base64 36 +``` + +`LAMBDAMAIL_MASTER_KEY` deserves particular care.

Fix anything it flags before going further — +particularly an RBL listing, which will not fix itself. + +## Step 4 — Create the first administrator + +Nothing else creates a mailbox, so without this there is no way into the +console: + +```bash +make create-admin EMAIL=you@example.com PASSWORD='a long passphrase' +``` + +This creates the domain if needed, the mailbox as `SUPER_ADMIN`, its standard +folders, and the four system aliases (`postmaster@`, `abuse@`, `dmarc@`, +`tlsrpt@`) that the published DNS records point at. + +Then: + +1. Sign in to the webmail at `https:///user/login`. +2. Go to **Settings** and enrol a second factor. The admin console requires + one and will refuse to open until it exists. +3. Sign in to `https:///admin/login`. + +## Step 5 — DNS records + +With a Cloudflare token set, the service reconciles the zone on start and every +six hours after that. Watch it: + +```bash +docker compose logs -f protocols | grep "DNS reconcile" +``` + +It is idempotent, and it never deletes records it did not create — anything +unexpected is reported as a conflict rather than overwritten. + +Without a token, add the records by hand.
