Hi Railway Support,

I am hosting a FastAPI backend on Railway.

SMTP emails are not working.

I tested the connectivity from the Railway Console.

1. DNS resolution works:

python -c "import socket; print(socket.getaddrinfo('smtp.gmail.com',587))"

This returns Gmail IP addresses successfully.

1. HTTP internet access works.

2. But TCP connection to smtp.gmail.com:587 always times out.

Command:

python -c "import socket; s=socket.socket(socket.AF_INET,socket.SOCK_STREAM); s.settimeout(10); s.connect(('142.250.4.108',587))"

Result:

TimeoutError: timed out

I also tested with two different Gmail accounts and different App Passwords.

Could you please verify whether outbound SMTP traffic on port 587 is blocked or restricted for my Railway service?

Thank you.
