I already installed discourse in a server behind a firewall. And an HTTP proxy server was set up by
```plaintext
export https_proxy=http://192.168.1.2:3128
export http_proxy=http://192.168.1.2:3128
```
But I found that the email sending function is not ok. It’s always timeout, so, I guess it caused by the network setting.
Thanks for your time to read my issues. Any hints are very appreciated.

Your SMTP server is also behind the same firewall?

My SMTP server is the public service from the Internet. Do I need a sock proxy server?
