wildduck VS Mailu

Nodemailer author here. I now publish all my libraries/tools (like Nodemailer) under some permissive license (MIT, MIT-0, ISC). This gives the opportunity to use such a library without issues, and the end user never knows about these tools anyway. For example if I build a OSS software and commercial software that both use such library, then it is easier to manage it under permissive license - I don't want copyleft licenses turning up in my commercial software even if I'm the owner.

For OSS applications, I use EUPL (eg. https://wildduck.email/) or AGPL copyleft licenses. The license does not stop anyone using it as an application, but at the same time people are not free to copy, rename and sell it either.

Even though I have self-hosted things individually (eg: my Ghost blog on a RasPi connected to my home WiFi), something which I've always been concerned about is the separation of all these services, since they must have APIs and access rules. What's an ideal way of setting up a multi-service server like this, and what security policies should I implement. Additionally what are some must haves that you have running on your servers?

I understand self-hosting is a huge labour of love, and I have no qualms in investing time/effort learning :)

The largest WildDuck installation manages 100k+ email accounts with around 300TB of stored emails. So it does not always have to be one of the old and tried softwares. https://wildduck.email/

or install https://wildduck.email or mail in the box type of server, just host it yourself. Wildduck web interface allows you to make unlimited alias already.

I want to create an email service. I want to use MongoDB as a storage option. I want to store every email in a that DB but I can't find an email server technology that supports that. Are there any technologies that support that out there? As far as I could go only wildduck supports that but I don't like their documentation, setup, ecosystem, and more, so I'm looking for an alternative technology.

I use: https://github.com/nodemailer/wildduck for Mails.

I had noticed this/similar feature on wildduck mail server. Checkout the Advanced Security section there, might be what you are looking for.

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.
