Install Discourse for development using Docker

Hello, although everything seems to be working after following this tutorial on an Ubuntu 26.04 machine, no emails appear to be sending.

I did start d/mailhog in a dedicated terminal, and I can see the HTML/CSS code of the email sent after a test user registered, but the user receives nothing at the email address I provided…

What did I miss, and how can I fix it? :folded_hands:
