Wire production email secrets through Forgejo deploy.
Deploy workflow now writes MAIL_* and APP_PUBLIC_BASE_URL from Actions
secrets into the server .env so Resend SMTP works after domain verify.
Document Resend-only setup, Forgejo secret names, and prod expose-token off.

Production email with Resend (operator)

BilHej sends password-reset mail via SMTP (Spring JavaMailSender). You do not need the Resend Java SDK from their onboarding snippet—only env vars on the server.

Security

  • Never commit re_... keys to git. Put them only in the server .env.
  • If an API key was pasted in chat or logs, revoke it in Resend → API Keys and create a new one.

1. Verify bilhej.se in Resend

  1. ResendDomains → add bilhej.se
  2. Add the DNS records Resend shows (SPF, DKIM; DMARC optional) at your domain registrar
  3. Wait until status is Verified

Until the domain is verified, MAIL_FROM=noreply@bilhej.se will fail. For a quick API test only, Resend allows onboarding@resend.dev → your own inbox—not for production.

2. Production .env (SMTP, not SDK)

On the server (file used by docker-compose.prod.yml):

APP_PUBLIC_BASE_URL=https://bilhej.se
MAIL_HOST=smtp.resend.com
MAIL_PORT=587
MAIL_USERNAME=resend
MAIL_PASSWORD=re_your_new_api_key_here
MAIL_FROM=noreply@bilhej.se
Variable Resend value
MAIL_USERNAME Always the literal string resend
MAIL_PASSWORD Your API key (re_...)
MAIL_FROM Any address on verified domain, e.g. noreply@bilhej.se

3. Deploy

Run Deploy to Production in Forgejo (pipeline only—no manual rsync).

4. Smoke test

  1. https://bilhej.se/logga-inGlömt lösenord?
  2. Email that exists in users
  3. Check inbox and spam
  4. Resend dashboard → Emails should show the send
  5. On failure: docker logs bilhej-backend-prod 2>&1 | grep -i mail

Fallback: reset links still log when MAIL_HOST is empty.

Local dev

Keep using Mailpit (docker compose up, http://localhost:8025). Do not point local Docker at Resend unless you intend to send real mail.
