Hello Everyone,
I'm trying to install Mailman3 on an Ubuntu 22.04 server right now, and I've run across a few obstacles that I'd like help with. I've followed the installation instructions, but I'm having trouble in a couple places, so I was hoping an experienced someone might help me out.
This is what I have completed thus far:
- I used the apt-get package manager to install Mailman3.
- PostgreSQL was configured as the database backend.
- Postfix was installed and set up to function as the Mail Transfer Agent (MTA).
- Assemble Postorius, Hyperkitty, and the Mailman3 core.
Problems I'm Having:
Postorius and Hyperkitty Connectivity: I'm having problems making sure that the Mailman core is correctly connected to Postorius and Hyperkitty. I get a 502 Bad Gateway error when I try to access the web interfaces. Despite checking my specifications, I am unable to identify the problem.
Problems with Email Delivery: I'm also having trouble with email delivery. Although Mailman appears to be receiving emails, it is not appearing to be sending any out. I think there might be a Postfix problem, but I'm not sure how to solve it.
Generally Suggested Practices: Are there any particular security best practices I should be aware of when it comes to Mailman3 installations? I want to confirm that my configuration is both performance- and security-optimized.

I would be grateful for any advice or resources! It would be really beneficial if someone with a similar setup could share their settings or troubleshooting procedures.
Thank you in advance.
