Moohoo, dear community!
With the release of Debian 13 (Trixie), the question arises for you as administrators: How can you perform a smooth dist-upgrade from Debian 12 (Bookworm) – especially on systems running mailcow? A commonly overlooked pitfall: Exim.

Moohoo everyone
It’s time for another update.
This time, we’ve updated Rspamd to 3.11-2, upgraded MariaDB to 10.11, and moved our Docker images from Docker Hub to GitHub. Nothing too wild.
Important Fix: Dovecot & Netfilter
Previously, Dovecot allowed multiple failed login attempts within a single session without being properly detected by Netfilter. This has now been fixed.
In this blog post, I’ll walk you through the current state of the nightly branch of mailcow. The biggest highlight is of course the support for external authentication sources.
To make this new feature as seamless and user-friendly as possible, we had to introduce some adjustments — you’ll see what I mean.
But first, a huge thank you to everyone in the community who tested the nightly branch and provided valuable feedback. 🙌 At this point, most of the work is done, and we’re only expecting small bug fixes if needed. Some users have already adopted the nightly branch in production and are happy with it — which is fantastic!
