* feat(mail): support gzip compressed email storage in D1 raw_blob column Add ENABLE_MAIL_GZIP env var to optionally gzip-compress incoming emails into a new raw_blob BLOB column, saving D1 storage space. Reading is backward-compatible: prioritizes raw_blob (decompress) with fallback to plaintext raw field. Includes DB migration v0.0.7, docs, and changelogs. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: gzip fallback on missing column + decouple resolve from handleListQuery - email/index.ts: gzip INSERT failure now falls back to plaintext INSERT instead of silently losing the email (P1: data loss prevention) - common.ts: add handleMailListQuery for raw_mails-specific list queries with resolveRawEmailList, keeping handleListQuery generic - Replace handleListQuery → handleMailListQuery in mails_api, admin_mail_api, user_mail_api (only raw_mails callers) - Add e2e test infrastructure: worker-gzip service, wrangler.toml.e2e.gzip, api-gzip playwright project, mail-gzip.spec.ts with 4 test cases Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: address CodeRabbit review feedback for gzip feature - Use destructuring in resolveRawEmailRow to truly remove raw_blob key - Narrow fallback scope: only fallback to plaintext on compression failure or missing raw_blob column, re-throw other DB errors - Clean unused imports in e2e gzip test Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: add try-catch in resolveRawEmail to prevent single corrupt blob from failing entire list A corrupted raw_blob would cause decompressBlob to throw, which with Promise.all in resolveRawEmailList would reject the entire batch query. Now catches decompression errors and falls back to row.raw field. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(mail): align sendAdminInternalMail with gzip storage path sendAdminInternalMail now respects ENABLE_MAIL_GZIP: compresses to raw_blob when enabled, with fallback to plaintext on failure. Added e2e test verifying admin internal mail is readable under gzip. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(e2e): match admin internal mail by body content instead of encoded subject mimetext base64-encodes the Subject header, so the raw MIME string does not contain the literal subject text. Match on body content (balance: 99) which is plaintext. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(e2e): add WORKER_GZIP_URL guard and length assertions in gzip tests Address CodeRabbit feedback: - Skip gzip tests when WORKER_GZIP_URL is not set to prevent false positives - Assert results array length before accessing [0] for clearer error messages Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(mail): narrow gzip fallback scope and fix webhook query compatibility - sendAdminInternalMail: separate compress vs DB error handling, only fallback to plaintext on compression failure or missing raw_blob column, rethrow other DB errors (aligns with email/index.ts) - Webhook test endpoints: use SELECT * instead of explicit raw_blob column reference, so pre-migration databases don't 500 - Docs/changelog: clarify that db_migration must run before enabling ENABLE_MAIL_GZIP Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(telegram): use generic Record type for raw_mails query result Align with other query sites — avoid hardcoding raw_blob in the TypeScript type annotation so the query works with or without the column after migration. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor(models): add RawMailRow type and unify raw_mails query typing Add RawMailRow type to models with raw_blob as optional field, replacing ad-hoc Record<string, unknown> and inline type annotations across webhook test endpoints, telegram API, and gzip utilities.

E2E Tests
End-to-end tests for Cloudflare Temp Email using Playwright and Mailpit, fully containerized with Docker Compose.
Prerequisites
- Docker and Docker Compose
Quick Start
cd e2e
# Build, start all services, run tests, and exit
npm test
# Clean up containers and volumes
npm run test:down
npm test runs docker compose up --build, which:
- Starts Mailpit (SMTP on :1025, HTTP API on :8025)
- Builds and starts the Worker (wrangler dev on :8787)
- Builds and starts the Frontend (vite dev on :5173)
- Builds and runs the E2E runner (Playwright), which waits for services, initializes the DB, and runs all tests
The exit code reflects the test result.
Test Structure
| Project | Directory | What it tests |
|---|---|---|
api |
tests/api/ |
Worker API endpoints — health check, address CRUD, send mail via SMTP |
browser |

Frontend UI — login, inbox view, reply with HTML, XSS sanitization |
Services
| Service | Container | Port | Purpose |
|---|---|---|---|
| Mailpit SMTP | mailpit |

| Mailpit HTTP | mailpit |
8025 | API to verify captured emails |
| Worker | worker |

Test Results
Test results and HTML reports are exported via volumes:
e2e/test-results/— test artifactse2e/playwright-report/— HTML report
Configuration
The E2E worker uses fixtures/wrangler.toml.e2e with:
E2E_TEST_MODE = true— enables test seed endpointDISABLE_ADMIN_PASSWORD_CHECK = true— allows unauthenticated admin callsDEFAULT_SEND_BALANCE = 10— allows sending without admin approval- SMTP pointed at Mailpit container (
mailpit:1025)
