Because of the ridiculous decision from #dovecot, replication between two servers won't be possible anymore.
I have - against all advices - ran my own mail server since 2019. It has served me and my family pretty well over these years.
Now it's time to migrate. And that's painful.
It looks like I'm going to Stalwart. Just to get the infrastructure ready - Foundation DB cluster, two Garage nodes for replication, Zabbix, etc, took a lot of time.
I hope #Stalwart will bit worth it.
Oh, and in case anyone is curious, here's what I am self hosting these days:
- Keycloak - OpenID Authentication Provider
- Nextcloud - Private cloud service
- #Vaultwarden - Open Source implementation of BitWarden server in Rust
- Sonatype Nexus - Artifact Repository I use for Maven/Containers/NPM/etc...
- #OneDev - An open source git forge similar to GitLab
- #Stalwart - Mail Server with lots of features
- #PenPot - Open Source alternative to #Figma
I've been working on the infrastructure for Launchpad023. Everything declaratively configured because servers should be cattle not pets.
I've put it up on Codeberg if anyone wants to take a look.

I can finally receive, send and reply to and with emails of my own domain(s)
That took 7 years of self hosting, a lot of research and, admittedly, a SMTP relay for outgoing emails, because the extra work to maintain a proper IP reputation (among others) didn’t seem worth it (yet ?)
Using Stalwart helped, being on K3S didn’t…
All that’s left if properly hooking up Postgres, some storage engine and a k8s configmap to track the Stalwart configuration file

I’m testing #LLM spam detection in #Stalwart mail and this one is the first and quite an interesting case of false positive. The email in question was a legitimate Apple annual subscription reminder for Telegram Premium:
advokatt
Francis Augusto Medeiros
Deven Phillips
sherbang
DocYeet 
alice 🪞♥️ 🎩🐇
El Pregoner del Metall
kravietz 🦇X-Spam-LLM: HARMFUL (The message impersonates an Apple invoice for a Telegram Premium subscription and includes suspicious/non-Apple account details ([email protected]) suggesting a phishing/fake receipt intended to trick the recipient into clicking support/cancellation links)
X-Spam-Score: ham, score=4.60
P.S. yes, I pay for Telegram Premium to be able to download tons of videos that later end up on video.echelon.pl without throttling
@reinier er is nog wel een nieuwkomer om mail zelf te hosten: #Stalwart. Heb het eens geprobeerd te draaien, maar niet doorgezet. Lag meer aan mij dan aan hen.
Recent hebben ze ook “Collaboration” features toegevoegd, wat contacts en calendars betekent:
https://stalw.art/collaboration/
Maar dit is dan wel iets wat je zelf moet gaan hosten, weet niet of je dat zoekt?
I’m just testing #Stalwart SMTP server and… oh wow.
The simplicity of the server that incorporates SMTP, IMAP, POP3, JMAP (!), spam controls, DKIM and dozen of other features is impressive.
Stalwart gains even more when compared with my traditional stack based on Postfix, Dovecot and Rspamd with lots of rather ugly hacks…
