Postal VS Mailu

It looks like I'm not the only person who has faced this. apache-based images require buster, for instance, and some docker images that rely on Ruby face issues too (for example, I decided to try setting up Postal but it looks like it's facing the same issues).

A great self-hosted pairing might be Postal https://github.com/postalserver/postal

Previously I’ve used Postal, which is not simple but okay. Can I do better? Isn’t why I’m writing this?!

This is postal: https://github.com/postalserver/postal

Try Postal.

https://github.com/postalserver/postal is my go to favorite.

Consider installing Mailu instead, which is a single Docker container with a full mail server and Roundcube on top. Very easy to install.

I've been using Mailu (https://mailu.io/) for years and have had no problems. I love that it has the concept of domain admins so that people can manage mailboxes for their own domains. DNS isn't automatic, but meh. Upgrading is easy (Docker + automatic migrations).

Mailu is pretty solid for personal use and is lighter on memory than Mailcow

While hosting mail isn't easy, Mailu and similar projects make it way easier than it used to be.

Mailu on a cheap VPS: https://mailu.io

Mailu. It’s a docker image that has the whole email system pretty much all done for you. If you don’t know docker, learn it it’s well worth it.

So as the title says, I'm trying to set up a dockerized mailu server. I've done the docker compose setup from the mailu.io site, except it doesn't seem to work and I'm not exactly sure why. I'm guessing I'm just not entering in some information correctly, but I don't know for sure. One thing I know I'm not sure on is the db url and what exactly is it supposed to be. I don't remember the exact error I'm getting, as I'm not in front of my computer at the moment, but I do know it was the admin container that wasn't working properly. Either that or I don't have my DNS set up correctly.
