I'm on the Pro plan and need outbound SMTP access for email validation, but all SMTP ports appear to be blocked on my deployment.

According to your documentation (https://docs.railway.com/reference/outbound-networking), SMTP should be available on Pro plans and above. However, when I SSH into my service and run your official diagnostic command, all SMTP ports are unreachable:

Results:

Use Case:

I'm building an email validation service that needs to:

• Connect to mail servers' MX records on port 25 for SMTP verification

• Perform SMTP handshakes to verify email addresses exist (not sending actual emails)

This is standard email validation - similar to services like ZeroBounce, NeverBounce, etc.

What I've Tried:

Verified I'm on Pro plan

Redeployed service multiple times

Tested multiple SMTP hosts (gmail, outlook, etc.) - all blocked

Confirmed UFW firewall is not blocking (status: inactive)

Request:

Could you please:

• Verify if SMTP outbound access is enabled for my account/project?

• If not enabled by default, can you enable outbound SMTP ports (especially port 25) for email validation?

• Let me know if there's a specific configuration or approval process needed for SMTP access on Pro plans?

• This is for legitimate email validation (checking if email addresses are deliverable), not for sending bulk emails or spam.
