Request to enable outbound SMTP/HTTP for email service integration

Question

Hi,

I'm running a Laravel application on Railway that needs to send emails via Mailgun. Currently, all outbound connections to email services are being blocked:

* **SMTP connections** to `smtp.mailgun.org` (ports 25, 587, 2525, 465) — timeout
* **HTTP API calls** to `https://api.eu.mailgun.net` — connection refused

Both SMTP and HTTP transports fail with connection timeouts/refused errors.

**Current workaround:** Using log mailer, which only logs emails locally and doesn't send them.

**Request:** Can you whitelist outbound connections to Mailgun's SMTP and API endpoints, or provide guidance on how to enable outbound email delivery on Railway?

**Service details:**

* Service: house-expenses-backend
* Framework: Laravel
* Email provider: Mailgun (EU region)

Thanks, Muhammad Zahid

SMTP is only available on the Pro plan. Alternatively, you can use a HTTP compatible transactional mail service, such as Resend.
