Mailu VS Haraka

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.

postale.io has an MX record that points to mail.postale.io, which resolves to an AWS IP address (probably an EC2 instance) and has Haraka listening on port 25 (if its SMTP banner can be believed)

I found that Zerodha uses Haraka and Karan–their DevOps guy, mentioned it is easy-setup and performant.

The next time this happens i'll move to a self hosted solution, like haraka or anonaddy

Haraka Like: Simple to hook into the processing pipeline Dislike: Node.js and had some issues with stability when I last tried it

Having another SMTP as a choice is cool but not as fun as something that is way more configurable (ex. Haraka), or API driven (a la Postal).

Look at Haraka: http://haraka.github.io/

For the record, I'm using dovecot (https://www.dovecot.org/) for IMAP and Haraka (https://haraka.github.io/) for SMTP.

I run my own mail servers for small projects, though for my main email I've actually switched to ProtonMail.

It's never been easier to self host your email with projects like the following around:

- https://foxcpp.dev/maddy/

- https://github.com/albertito/chasquid

- https://github.com/haraka/haraka

Of course the usual dovecot + postfix setup is great for learning even if a bit complicated.

Haraka (https://haraka.github.io/) is a plugin-based mailserver written in JavaScript. I've messed with postfix before but found Haraka easier because instead of arcane configuration files I can just read, copy, and tweak a plugin to suit my needs. Policies for receiving, storing, forwarding, and ignoring mail can be arbitrarily complex.
