I'm using Stalwart. For clients I'm using sterna on mobile and aerc on the desktop. I'm using JMAP instead of IMAP. One thing I really like about Stalwart is that is using JMAP to update its configuration. It is currently a little rough, but I do think it will much better in the end. It allows one to have a declarative configuration of resources like Folders, tags, aliases, sieve scripts, etc.
\nThe installation recommends you to use curl | sh - (no, thanks), but the script is well written so it can be used to learn how to setup Stalwart. Given how much care went into the installation script, I really do wonder why they don't also write down a document. Their docs as another comment mentions are verbose and not very useful. I've yet to figure out how to tell its spam filter about a false positive.
Stalwart does its best to work out of the but you still need to troubleshoot things (e.j. use https://www.learndmarc.com/ to check your configuration). There are things like reverse DNS that Stalwart can't help you setup.
\nUpdating Stalwart so far has been a breeze. Just download the new executable, unzip and restart the service. There was a big change from 0.15 to 0.16 but so far no manual upgrade process has been needed.
\nBesides their docs, their support portal is mostly an LLM answering questions, which as one might guess is not very useful.
\nSome small QoL changes I'd like to see:
\nSo far my experience with Stalwart has positive. Its a good way to start self-hosting email, but I do worry about how much they are pushing LLMs into their main product. I may end up moving to another server later.
\nOne thing I'd like to improve later is having a jmap based syncing tool. Similar to https://github.com/elizagamedev/mujmap. (While reading the mumap code and dependencies I was surprised to learn that notmuch is not thread safe).
