Replace all Postmark references (POSTMARK_API_KEY, POSTMARK_SENDER_ADDRESS)
with SMTP configuration (SMTP_HOST, SMTP_PORT, SMTP_USER, SMTP_PASSWORD,
SMTP_FROM) across documentation, deployment config, template, and test.
- README.md: architecture diagram (Postmark → SMTP) and configuration table
- docker-compose.yml: POSTMARK_* env vars replaced with SMTP_* required vars
- .env.template: POSTMARK_* entries replaced with SMTP_* entries
- test/integration.sh: POSTMARK_* test exports replaced with SMTP_* test values
Adds a test that validates the fix for the web UI crash when
VITE_NOTIFIER_RELAY is not set. The test exercises the guarded
pattern (ternary guard before calling normalizeRelayUrl) that
prevents the TypeError crash on undefined input.
Closes mailship-4ic
The web UI crashed on load when VITE_NOTIFIER_RELAY was not set
because normalizeRelayUrl(undefined) calls url.match(...) on the
undefined argument, producing:
TypeError: can't access property 'match', A is undefined
Fix: guard with a truthy check before calling normalizeRelayUrl,
and early-return from loadAlerts when NOTIFIER_RELAY is undefined.
Fixes bead mailship-4ic
- test/integration.sh: runs full E2E flow against fresh server
- pnpm test and pnpm test:server scripts added
- Root endpoint handles missing web UI gracefully (returns JSON)
- database.ts reads DATA_DIR env var for test isolation
- .gitignore updated for test artifacts
