SMTP port 587 timeout, is outbound SMTP supported on Railway?

[ravichandra-eluri]

Description:

I was building a notification service and kept getting i/o timeout errors when trying to send emails via SMTP on port 587. Took me a while to figure out it might be a platform restriction and not a bug in my code.

A few questions:

• Is port 587 blocked on all plans or just the trial?
• Is there any plan to support outbound SMTP?
• What is the recommended approach for sending emails from a Railway service?

Based on the Railway docs at https://docs.railway.com/networking/outbound-networking#email-delivery,

SMTP is only available on the Pro plan and above.

Free, Trial, and Hobby plans must use transactional email services with HTTPS APIs. SMTP is disabled on these plans to prevent spam and abuse. However, even when SMTP is available, we recommend transactional email services with HTTPS APIs for all plans due to their enhanced features and analytics.

They also showcase examples with email services like Resend and SendGrid.
