Hello Railway Team,

I'm running a Chatwoot instance on Railway (Project: steadfast-harmony, Service: Chatwoot) and experiencing timeout errors when trying to send emails via Gmail SMTP.

Issue:

- IMAP connection to imap.gmail.com:993 works perfectly ✓

- SMTP connection to smtp.gmail.com:587 fails with timeout after 5 seconds ✗

- SMTP connection to smtp-relay.gmail.com:587 also fails with timeout ✗

Error Message:

"Timeout to open TCP connection on to smtp-relay.gmail.com:587 (exceeds 5 seconds)"

Current Network Configuration:

I can see that egress control is enabled with allowed domains, but Gmail SMTP domains are not included.

Request:

Could you please add the following domains to the egress whitelist for my project?

- smtp.gmail.com (port 587 and 465)

- smtp-relay.gmail.com (port 587)

- imap.gmail.com (already working, but to ensure it remains accessible)

Additional Information:

- Service: Chatwoot (chatwoot-production-b5cc.up.railway.app)

- Project ID: steadfast-harmony

- Using App Passwords for authentication (not plain passwords)

- IMAP is working fine, only SMTP egress is blocked

Thank you for your help!
