I can recommend Stalwart [1] which is a complete mail service contained in a single binary, that doesn't really have any external dependencies, and is really easy to install and update.

I've looked (and tried) a few other projects in the past, but Stalwart was the easiest to setup, and I haven't had any issues with it so far.

It’s also what Thunderbird is using to build their paid email hosting. Seems like a very ambitious project mostly done by a single person – impressive!

Wow! I was just about to comment how email is the one thing where I wish something that didn't follow the unix philosophy existed. Exactly due to this, it is easy to set up a mail server but it is hard to think of all the things around it: spam, fishing, dmarc, dkim, spf, etc.

This looks really nice, especially also for saas projects.

I'm not looking to self-host my email, but this looks fantastic. It's making me reconsider the decision, hm. Thank you for this.

Has anyone compared Stalwart with say Mox or Maddy, in practice?

They all look about the same from a newb's perspective.
