punkero.orgThe relay assets have been added to Codeberg in a new repo, nothing special just the odds and ends used to run the VPS and service, couple of scripts, etc.
Mostly reused bits & bytes from my personal Forgejo forge.
The relay has been updated to the Chatmail release 1.11.0, all 88 tests passing with a remote relay (the tests are quite comprehensive in simulating actual, real chats).
Another new Debian 12 kernel was released fixing more CVEs, the relay was rebooted and retested, working as expected. Kernel devs keeping us safe.
Added a '-f file' option to cmrelaymon (0.0.2 tag) for dynamically loading the environment file used by systemd, a better way of debugging instead of 'set -a; source ...; set +a' (and it won't pollute your current environment)
I made a widget to monitor the relay service endpoints, designed to be used with an upstream like healthchecks.io or similar
The Info page has been juiced up a bit to outline the relay VPS details. I found the hardest part in setting up a low cost yet resilient relay to be which high performance DNS service to use.
Gcore DNS was chosen over Bunny DNS specifically because Gcore hosts the 2 nameservers in 2 different AS routes for internet outage fault tolerance. Bunny uses a single AS for both endpoints, so a single BGP config error could take them both out at once. SPoF
Relay operators: Debian 12 kernel 6.1.0-45 was recently released and ready for upgrade. Fixes a ton of CVEs.

To enable Audio/Video calls in DeltaChat: go to Settings -> Advanced and enable "Debug Calls". Ensure you grant Camera and Microphone access in your device settings and are running the latest app version.
Relay operators: if running a firewall, AFAIK the UDP port range is not currently static so one has to open all non-privileged UDP ports (1024-65535) for the TURN relay.
https://punkero.org is one of many chatmail relays, helping to provide encrypted, decentralized instant messaging for everyone. Anonymously.
If you are new to "chatmail", the concept is straightforward - take the fundamental protocols developed for email infrastructure and leverage them for use with fully end-to-end encrypted, instant private messaging.
It's super easy to get started and use, not to mention reliable, fun and open source.
DeltaLima 🐧There is a new Chatmail / Delta Chat Relay in the hood 😎
Happy chatting!

RC 🌳Have been playing with and looking closely at #deltachat for the past couple of weeks. Very impressive.
I set my own #chatmailrelay here for those who want to give it a try: danneskjold.de
