Hosted-in-, public chatmail relay:

https://chtml.ca

e2ee one-to-one and group chat; takes less than a minute to create an account and requires zero personal info; federated with all other chatmail relays; native mobile and desktop apps..

Feel free to experiment grab an account; PM me here or add the chtml.ca admin account if you have issues or need a hand

23 is the number of currently active #chatmail relays we heart about by now. Only 6 are listed at https://chatmail.at/relays to complicate ongoing state-level blocking attempts. Please keep setting up #chatmail relays -- and thanks to all the early adopters and carers!

July 2025 some key contributors will do sessions in #Lille, France at @passthesaltcon
and discuss the state of efforts to scale #deltachat #chatmail and #webxdc to billions of people and bots, without any central points of control.

For anyone wanting to try the secure messaging app #deltachat there is now a local Aussie #chatmail server at https://chatmail.au

"if your social media network can go down it is not decentralized" they say and rightfully so. Same is true for much other infrastructure ... Energy, water, internet utilities ... And of course messaging. If your messenger can go down it's not decentralized. During 2025 we aim to make #deltachat and #chatmail infrastructure in particular into the most resilient and mass-user accessible private messenging utility out there ... If it isn't already :)

Organizational note: It might appear that #deltachat #chatmail and #webxdc contributors are easily "on the same page". In fact, there are many ongoing controversial discussions in backrooms and public spaces. We are dealing with tons of user perspectives and feedback, researcher and developer stances, many UX/UI considerations, complex implementation and platform adaptation. We are internally allowing contradictions and complexity ... See also Ashby's requisite variety https://edgeofpossible.com/ashbys-law-variety-organisational-change/

Would it be possible to run a #chatmail server on a VPS with #OpenBSD, #FreeBSD or #NetBSD?

#chatmail relays can serve 200k+ users on a small physical machine, are easy to setup and even easier to maintain. Chatmail relays enforce end-to-end encryption and rely on cryptographic verification for interoperability instead of IP reputation and spam checking magic. Tomorrow (Sunday) evening, @compl4xx will give a hands-on setup workshop in Hamburg https://cfp.eh22.easterhegg.eu/eh22/talk/NXTPXY/

The trajectory of E2E-encryption is about de-platforming: There shall be no central machines that can control the edges/peers, and the social groups and virtual centers they freely form.

Our #deltachat R&D around #chatmail relays and #webxdc apps all aim to realize such a "zero-platforms" fully E2E-encrypted interaction model. However, this is *not* just about cryptographic cleverness. Rather it is about usable anti-authoritarian designs, as explicitly stated in January https://delta.chat/en/2025-01-23-webxdc-no-billionaires

Störung!

Das Hostsystem hat eine Störung.

@delta

Your chatmail relay is great for private conversations!
But it's also great for some Alertmanager infomails!

Easter/April offer if you are onboarding a small group of family/friends to #deltachat and/or want to setup a insta-federated #chatmail relay let us know about any issues. Just post on fediverse and tag us. In case of bugs/issues we'll see to privately set up a support chat to help sort out any issues, or file accordingly to our development tracker. We want Delta to work flawlessly for private chatting and to better understand any remaining irritations or problems. Thanks and enjoy :)
