Hello!

I installed Smartermail for Linux on an on-premises server using Ubuntu 24. The installation is very simple, and it runs as expected.

However, when I perform the same installation using a cloud server (in my case, OCI - Oracle), the Smartermail web interface does not work.

I believe it has to do with some internal adjustment on the VM, because unlike using an on-premises server with a public IP, the cloud VM uses a private IP with NAT to a public IP. All the firewall and IP routing settings are correct (especially since I run dozens of servers in this same environment, including some Smartermail installations, but on Windows).

The problem is likely some configuration on Linux... I remember having the same issue when I installed an Antispam on Linux, but a specialist made some adjustments to make it work. I'm not a Linux specialist, so I’d like to know if anyone has experienced this and how I can resolve it.

Thank you.
