No hi ha res que pugui fer un administrador d'un servidor #chatmail (#DeltaChat) per a desxifrar els missatges que passen a través del seu servidor. Els missatges es xifren en els dispositius dels usuaris, el servidor chatmail només fa de transport dels mateixos. I l'aplicació DeltaChat xifra tot per defecte, no és configurable, no es pot desactivar el xifrat.
Ningú pot demanar a un administrador d'un servidor chatmail els continguts dels missatges perquè no pot fer res de res. 💪

Is there anyone hosting a #chatmail instance on a #BSD?

If yes, how was your experience setting it up and maintaining it?

#FreeBSD#DeltaChat #email #openbsd #netbsd

Amount of hours spent to keep a default #chatmail onboarding relay with 500k active addresses running: near zero.

Glancing at stats sometimes: two million messages per day. CPU and IO load at 20% max. 500gb raid1 ssd meandering around 60 percent full. There is room for various optimizations but no big need currently.

end-to-end encryption with metadata minimization is best if servers are boring. No clustering or enterprise license needed, no "SRE team" either.

Tomorrow at #CFC25 there are two sessions about #DeltaChat:

How to set up a #chatmail relay server, an easy way to make your first timid steps with server administration: https://pretalx.c3voc.de/chaos-feminist-convention-2025/talk/TWRT8X/

And an overview on #webxdc apps, and how they bring back computing to your social context, locking out the tracking companies: https://pretalx.c3voc.de/chaos-feminist-convention-2025/talk/9VMYAJ/

The webxdc talk will also be streamed, if you want to join remotely :)

Two of our teams just gave talks at the @passthesaltcon 2025 conference in Lille:

@Xeniax tells the story of "federated messaging" waves and her usable security research, emphasizing "availability" as a key issue

@hpk starts off with prioritizing usable security and walks through #chatmail transport layer security goals and #deltachat end-point security status, upcoming releases and prospective work on improving metadata and other goals

We are basically doing what #signal and in particular moxie refused to do or declares impossible: federation.

Both #email and #activitypub ecosystems are all about federation.

However, #deltachat is vertically centralized in that all UIs use the same #rust core which implements all networking, encryption, chat/group/message logic in a single centralized place. The now 40+ #chatmail mail relay network is driven from centralized code.

At each level replication and federation is built in.
