It's an enterprise feature 😡

After more than three months of focused work, we are thrilled to announce the release of Stalwart v0.16. This is easily the most ambitious release we have ever shipped, with literally hundreds of new features, improvements, and fixes across every corner of the server.
#Stalwart mail distributes SLSA attestations 👍

These are basically digital signatures created automatically at build time on all binary artifacts from the project. The idea is that by verifying them - also automatically! - at downstream projects (e.g. OS packaging) you plug one possible supply chain attack hole.
@TheLancashireman @jwildeboer Sorry to step on your thread, but needing a 5-part series to self-host email is one of the reasons I stopped doing it. I only decided to take on the challenge again with the release of #Stalwart and honestly I'm so glad that I did. It's incredibly easy to run (a single Docker image), has an admin UI, helps you set up your DNS to improve your spam score, etc etc.
I know it's not for everyone. But I highly recommend it for first-time email self-hosters.

Bei meinem #CLT26-Vortrag hat noch gefehlt wie beim Einsatz des #Stalwart-Mailservers die per sendmail eingelieferten Mails noch ihr Ziel finden.
Die Lösung mit msmtp habe ich gerade dokumentiert - https://grupp-web.de/cms/2026/04/10/stalwart-mailserver-sendmail-auf-systemebene-wie-geht-das-zusammen/
