# Email + Integrations Audit (EM-01-19, IN-01-29) — agent #7

**Headline:** Broadly well-implemented. Primary issue: missing SMTP timeouts on sales transporter (HIGH — risks worker starvation). Plus 8 medium gaps in portal-email portId scoping, digest catalog key, receipt scanner config, presign TTL.

**Counts:** 0 critical · 1 high · 8 medium · 0 low · 30 passing

## 🟠 HIGH EM-XX: Sales transporter missing SMTP timeouts

- **File:** `src/lib/services/sales-email-config.service.ts:331-337`
- **What:** `createSalesTransporter` builds nodemailer transport with no timeout options. Compare `createTransporter` in `src/lib/email/index.ts:26-37` which uses `SMTP_TIMEOUTS = { connectionTimeout: 10_000, greetingTimeout: 10_000, socketTimeout: 30_000 }`.
- **Why it matters:** Hung SMTP relay can stall send-out indefinitely. Email queue concurrency=5, maxAttempts=5. Without socket timeouts, one stuck TCP connection holds a worker for nodemailer's 2-min default × 5 retries = 10min/job × 5 slots = whole pool blocked for 10min by a single flaky send.
- **Suggested fix:** Apply `SMTP_TIMEOUTS` constant to `nodemailer.createTransport` in `createSalesTransporter`.

## 🟡 MEDIUM EM-05a: Per-port branding not threaded into portal activation/reset emails

- **File:** `src/lib/services/portal-auth.service.ts:163-164`
- **What:** `issueActivationToken` and `issuePasswordReset` call `sendEmail(email, subject, html, undefined, text)` without the 6th `portId` argument. Without `portId`, `createTransporter()` uses global env SMTP. Branding is threaded into HTML via `getBrandingShell(portId)` but the SMTP transport falls back to global.
- **Why it matters:** Multi-port deploys: portal auth emails for port B go through global env SMTP, defeating per-port SMTP override.
- **Suggested fix:** Pass `portId` as 6th arg to `sendEmail` in both `issueActivationToken` and the reset send.

## 🟡 MEDIUM EM-07: CC/BCC not supported in main `sendEmail`

- **File:** `src/lib/email/index.ts:54-68`
- **What:** `SendEmailOptions` lacks `cc`/`bcc`. Sales send-out path also lacks them.
- **Suggested fix:** Add optional `cc`/`bcc` to `SendEmailOptions`. Low urgency.

## 🟡 MEDIUM EM-11: Bounce-to-interest linking not implemented

- **File:** `src/lib/services/sales-email-config.service.ts:13` (header comment)
- **What:** `getSalesImapConfig` exposes IMAP creds but no BullMQ worker reads IMAP. Failed deliveries don't update `document_sends.failedAt`.
- **Suggested fix:** Wire BullMQ recurring job using imapflow to scan inbox for bounce NDRs, match against `document_sends.messageId`. Phase 7 §14.9 deferred.

## 🟡 MEDIUM EM-16: Notification digest uses wrong catalog key for subject resolution

- **File:** `src/lib/services/notification-digest.service.ts:161-169`
- **What:** Calls `resolveSubject` with `key: 'crm_invite' as any` because `'notification_digest'` is not in `TEMPLATE_KEYS` in `src/lib/email/template-catalog.ts`.
- **Why it matters:** Admin-set CRM invite subject override bleeds into digest emails.
- **Suggested fix:** Add `'notification_digest'` to `TEMPLATE_KEYS`; update digest service to use it.

## 🟡 MEDIUM IN-11: Presigned URL TTL fixed at 900s for portal downloads

- **File:** `src/lib/storage/index.ts:240-254` (`presignDownloadUrl`); `src/lib/services/portal.service.ts:350` (`getDocumentDownloadUrl`)
- **What:** `presignDownloadUrl` defaults `expirySeconds=900` (15min). Sales send-out correctly overrides to 24h. `getDocumentDownloadUrl` calls without expiry → 15min default.
- **Why it matters:** Portal users opening their doc list and clicking after >15min get 403.
- **Suggested fix:** Pass `expirySeconds: 4 * 3600` for portal download links, or sign on-demand from API.

## 🟡 MEDIUM IN-21: OpenAI receipt-scanner module-level instantiation, no credential health check

- **File:** `src/lib/services/receipt-scanner.ts:4`
- **What:** `const openai = new OpenAI();` at module level reads `OPENAI_API_KEY` at import. SDK throws on first call when unset; catch returns zero-confidence empty result. No admin-visible health check.
- **Suggested fix:** Guard `OPENAI_API_KEY` upfront with clear error. Add a health-check endpoint similar to `checkDocumensoHealth`.

## 🟡 MEDIUM IN-23: Receipt OCR ignores per-port config; hardcoded `gpt-4o`

- **File:** `src/lib/services/receipt-scanner.ts:19`
- **What:** `model: 'gpt-4o'` hardcoded; per-port `getResolvedOcrConfig` not consulted; `aiEnabled` flag does nothing. Module-level singleton OpenAI client.
- **Suggested fix:** Accept `portId`, call `getResolvedOcrConfig(portId)`, check `aiEnabled`, use `config.apiKey` and `config.model`. Branch on provider for OpenAI vs Anthropic.

## 🟡 MEDIUM IN-24: Stale "pdfme" references in comments/seed

- **File:** `src/lib/db/seed-data.ts:807`, `src/lib/services/document-templates.ts:573`
- **What:** Comments still reference pdfme even though the rendering path was removed; `tiptap-validation.ts:8` confirms pdfme retired. `document-templates.ts:648-652` throws ValidationError for non-EOI templates.
- **Suggested fix:** Update comments to reference pdf-lib AcroForm fill; remove "pdfme" from seed-data description.

## 🟡 MEDIUM IN-29: Umami `testConnection` throws instead of returning typed result

- **File:** `src/lib/services/umami.service.ts:80-101, 292`
- **What:** `loadUmamiConfig` returns null gracefully; all public APIs return null when unconfigured. But `testConnection` throws `CodedError('UMAMI_NOT_CONFIGURED')` instead of returning `{ ok: false, error }` like `checkDocumensoHealth`.
- **Suggested fix:** Return `{ ok: false, error: string }` to match Documenso convention.

## ✅ Passing checks

- EM-01 per-port SMTP override (`getPortEmailConfig` in `port-config.ts:136`)
- EM-02/03 default send-froms cascade (explicit `from` → `cfg.fromAddress` → env.SMTP_FROM → `noreply@${SMTP_HOST}`)
