docker-mailserver VS Mailu

I can recommend Docker mailserver (it also works with Podman). It is already pretty lightweight but you can even make it lighter and it has an active community as well as regular updates.

Use https://github.com/docker-mailserver/docker-mailserver or mailcow . They both provide reasonable default setup for spam detection and even UI for adjusting settings.

Check https://github.com/docker-mailserver/docker-mailserver It has almost everything in a single docker image. Email is not the easiest to implement with container(s), but that project has managed it.

I set up docker-mailserver[0] Monday in ~6 hours, most of which were me trying to be fancy using podman instead of docker and dealing with SELinux. But then again I did choose it over mail-in-a-box for just that level of customization. Obviously I can't tell how reliable it will be in the long run yet, but since it's using the classic Postfix/Dovecot stack I expect it'll be pretty stable

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. 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.
