Mattermost Installed, but not loading in browser

Alright, sounds good!

What’s your server operating system, if I can ask?

Distributor ID: Debian
Description: Debian GNU/Linux 10 (buster)
Release: 10
Codename: buster

Well, to start with, from a command line, run sudo apt-get install postfix -y

Postfix is already installed.

Ahhh okay, my apologies. Have you setup a SMTP relay on the server then, and given it a subdomain of your primary domain? For example, smtp.example.com

this is really good, thank you for sharing with us

You’re most welcome, and welcome to the Mattermost forum community, we’re happy to have you!

I’m not so worried about the IP address issue.
