Hello Railway Support,
we are running a production application on Railway where SMTP mail delivery is a critical functionality. Until recently, our application was able to send emails via SMTP.
Since a few days, this functionality has stopped working. Our customers are complaining because features that rely on email notifications are now broken. This is causing serious issues in production.
Could you please clarify what has changed regarding outbound SMTP traffic on Railway?
- Is SMTP (port 587 / STARTTLS) now blocked?
- If so, what alternatives or solutions are available to restore email sending from our application?
We urgently need to restore SMTP functionality, as it is business-critical.

Hey there! We've found the following might help you get unblocked faster:
- 🧵 issues sending emails - rails mailer
- 🧵 Email Configuration Fails with "550 5.7.1 Relaying Denied"
- 🧵 Nodemailer SMTP Authentication Issue (Error 535 5.7.8) with Railway Deployment
If you find the answer from one of these, please let us know by solving the thread!

Hello,
Outbound SMTP is allowed on the Pro plan, please do a full redeploy of your service for the new allow rules to take effect.
Best,
Brody

I can confirm that your application cannot do outbound SMTP, that should not be the case, going to raise this to the infra team.
