#deltachat ist a community messenger much more than a monetary focused enterprise. Its offspring developments, the growing #chatmail and #webxdc efforts are also community grounded.

Is there any other cross-platform FOSS messaging project, implementing #RightToExit on many levels, putting all interesting and sensitive computation and interactions into end users devices, constantly and radically denying centrality/control of billionaires and big-tech, to the extent currently possible?
#chatmail #deltachat #Webxdc #righttoexit

Some of you may remember posts where we talk about #deltachat being hardened to work under bad and adverserial network conditions where other messengers fail. Examples were Georgia, Russia and Iran at the time. But hardened network handling can be useful also during non-political turmoil like currently in Spain where there are some reports that DC messages get through where WhatsApp failed .... https://sonomu.club/@icaria36/114417052677227592

In any case, wishing all the people in Spain and Portugal quick recovery!

@delta@chaos.social I've just have received a batch of messages from a friend with a timestamp from 5 and 2 hours ago. This is consistent with the idea that the messages are queued locally until the connections is reestablished.

#deltachat

yes, currently if your chatmail or email servers fails you wouldn't be able to get messages.

The reason why #deltachat might work better is because it has been optimized to work in bad networks where states are intentionally trying to disrupt communications. Maybe the power outage in spain causes more random network behaviour (eg DNS failures) which delta is pretty prepared to deal with. In any case thanks for the notice and all the best with restoring power!
#deltachat

Still... I guess even #DeltaChat communications would fail me if the data center of my ChatMail server would be affected by a power cut, right? Or is there some kind of redundancy?

No idea how accidental this #blackout is, but it's a good chance to think how to make your mobile phone still useful when a bunch of servers (including your default ones) go off.
#blackout #deltachat

There is an ongoing massive electricity power #blackout in Spain and Portugal. Some of my friends are reporting that not even WhatsApp is reliable, working for some contacts and not for others. I'm still trying to understand how this is possible, and maybe it has to do with the recipients'nearest telecommunications more than the WA servers.

Anyway, fun fact, the friends who reached out did it via #DeltaChat

Still... (next)
#blackout #deltachat

I feel like #DeltaChat is gaining momentum 🤩

if you have any questions about #chatmail relays or #deltachat apps let us know :)
#chatmail #deltachat

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.

"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 :)
#chatmail #deltachat

wie kann man 2025 bei "sicheren" Messangern noch an @delta #deltachat vorbei kommen?
bzw. allein die Geschichte um die Entwicklung wäre vermutlich einen eigenen Artikel wert.
vielleicht mal @hpk kontaktieren.
#deltachat @holga @Delta Chat

the other reason for not formalizing procedures completely is that the requisite parts are still evolving. #deltachat #chatmail and #webxdc efforts each have their own dynamics, and the particular dynamics have particular sub dznamics and all the borders are constantly shifting, renegotiated.

Sorry if this makes getting an overview from the outside harder. We do try to constantly publish about our considerations and all coding work happens in public.
#chatmail #deltachat #Webxdc

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/
#chatmail #deltachat #Webxdc

I think the "no SIM required" is unterrated. I use #DeltaChat to send links from my phone to my PC to read them later. The UI is better compared to e-mail clients. And so simple to install/run. Big love for the devs!
#deltachat

Today we are unveiling two brand new features by ... drum-roll ... doing nothing:

- No "AI" integration involved or planned. Consequently, you don't need to teach your relatives how to disable AI!

- No proprietary server components: servers are fast, efficient and freely replicable, no permissions needed!

Moreover, our apps are easier to use and onboard with than SIM/phone number based apps: Multi-device and Multi-profile handling is a piece of cake.

I'm planning on trying #DeltaChat, how important is it to try to distribute the load accross chatmail servers?
If it's worth distributing it, are there any servers in France?
The list from https://chatmail.at/relays does not include anything but I don't know whether it's comprehensive.

what are the "Delta Chat missionaries" saying? 🤔 I am one of the #DeltaChat developers and I don't think any of us claim Delta Chat is some "state of the art" perfect or "the best", "the fastest" etc as other messengers boldly do.

The selection of parameters of comparison in your messenger table is also subject to what you think is important, it is hard to be neutral, also it seems the "metadata protection" field is not completely correct for Delta Chat:

#deltachat

Das ist die richtige Einstellung! 😉👍

Jeder Messenger hat seine Fans – aber manche Communitys sind echt anstrengend. Die größten Missionare findet man mit Abstand bei Threema, dicht gefolgt von Delta Chat. Kritik? Undenkbar. Da wird sofort erklärt, warum du das Problem bist.

Aber hey, sollen sie ruhig über mich herziehen – die kostenlose Werbung nehm ich doch gern mit. Wenn sie sich schon aufopfern, um meinen Namen in ihren Filterblasen zu verbreiten, will ich da nicht im Weg stehen. 😁

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

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 :)
#chatmail #deltachat

Isn't it ironic that a messenger that utilizes email protocols under the hood is pretty resistant to spam? For decades most people equated email with "spam" and yet, here we are. It's not the email protocols that cause spam but the fact that email adresses have been used as identity. #deltachat is moving away from this email address-as-identity model towards a cryptography based model where only chat contacts know your identity, and email is "just" the globally federated transport.
#deltachat

If you are using #deltachat with a #chatmail profile with private contacts there is no chance you are going to get spam. Why?

1) Spammers can't contact you based on your phone number like with other messengers.

2) Nobody knows your private address or cryptographic key except your contacts. Without that spammers/phishers can't contact you.

3) if joining a public group with unknown members better use a second chat profile which you can mute/remove as needed.

Privacy and peace of mind.

@Delta Chat - a #security question.

I am doing some security revamping to my #Debian desktop. Apart from regular level (disk encryption, login password, KeePassXC), I am adding master passwords to applications that do not connect with KeePass. While I have my keys and credentials already store there, I cannot find any way either to integrate the #DeltaChat desktop client with KeePass, nor to add a master password.
Am I missing something, or it is just not there?
#security #debian #deltachat @Delta Chat

#DeltaChat is so much better than Signal when it comes to hardware support. Get this: when setting up a new phone I lose access to previous conversations and media DESPITE having a synced desktop app. Why?

Well in Signal your desktop client is not a real client! Switching hardware with #DeltaChat was quick, easy and successful. Every client is real.👍

Signal:😖

I do wonder why they fail so hard there, as they generally have things figured out, too.

#openpgp #SoftwareLibre #messaging #chatmail #deltachat

#openpgp traditions and #signal both bind a cleartext identifier, phone number or email address, to a cryptographic key. It opens up attack vectors as the servers/orgs controlling this binding can interfere.

#deltachat avoids such cleartext identity bindings by creating random #chatmail addresses, as transport only. The cryptographic key becomes the identifier and we want it hidden from the transport layer. Only people being in end-to-end encrypted chat need to identify each other, after all.
#signal #openpgp #chatmail #deltachat

yes, our whole project is about proving in reality (meaning: working code) that email protocols can be streamlined for instant messaging. #chatmail relays provide low latency always end to end encrypted interoperable messaging. The family of #deltachat apps work with the permission free chatmail relay server network but also with run-of-the-mill email servers. Just make sure to use a dedicated chat address and don't mix classic and chat email on the same address.
#chatmail #deltachat

Dieses Beispiel zeigt sehr deutlich, dass die Möglichkeit, mehrere Accounts in einem Messenger einzurichten, auch ein Sicherheitsmerkmal ist. #deltachat erlaubt eine unbegrenzte Anzahl an Profilen (Accounts) pro Gerät. Jedes Profil verfügt über eine völlig unabhängige Kontaktliste. Die hätten zum Beispiel ein Profil für Pressekontakte und eines für Regierungsmitglieder verwenden können. So wäre es wohl nicht zu dieser peinlichen Panne gekommen.
#deltachat

We are testing #deltachat with 8 users since Friday with a self hosted server.

The experience is excellent and people are happy, especially with secondary device setup.

So far we ran into a few small issues.

- one user had pushes on one device delayed (its push. Remember apples guarantees on delivery…)
- a gif didn’t post but only the first frame (iOS)
- taking a photo doesn’t add it to the message, using the gallery works (Android)
#deltachat

Was ich schade finde, @delta, dass es nicht möglich ist, bei "Neuer Kontakt" die E-Mail-Adresse eine*r anderen DeltaChat-User*in direkt einzugeben.

ZB eben, wenn eine Person sich eine automatisiert verschlüsselte E-Mail-Adresse über nine.testrun.org eingerichtet hat und mir diese (über einen anderen Kanal) mitteilen möchte.

(Zählt ihr bei den Subdomains eigentlich hoch? Also von one.testrun.org, two, three ... twenty ..., usw.?)

Klar könnte sie mir auch den generierten Link über einen anderen Kanal schicken, aber die Mail-Adresse fände ich einfacher zu versenden.

#DeltaChat
#deltachat @Delta Chat

Gerade mal getestet:
Ich kann von meiner regulären E-Mail-Adresse (TLS-verschlüsselt) an meine DeltaChat-Mail-Adresse schreiben.

DeltaChat zeigt die Mail als "Chatmail" an, kein Problem.

Aber DeltaChat verweigert die ausgehende Mail, weil sie an den Empfänger nicht PGP-verschlüsselt werden kann.

So stellt DeltaChat sicher, dass die (ausgehende) Kommunikation darüber tatsächlich nur E2E-verschlüsselt möglich ist.

Das muss halt beachtet werden, wenn eins die eigene E-Mail-Adresse für die Nutzung mit DeltaChat verwenden möchte.

Ansosnten bietet DeltaChat ja aber nach der Installation die Möglichkeit, sich eine automatisiert generierte, verschlüsstelte System-Mail-Adresse einzurichten.

Und schon kann verschlüsselt kommuniziert werden :)

DeltaChat ist "mehr", als ein reiner Messenger.

Er verfügt über einen "XStore", über den neben kleinen Spielen weitere In-Apps genutzt werden können, wie zB
- To-Do-Liste
- Shopping-Liste
- Zeiterfassung
- Rechnungs-Aufteilung
- ein Mastodon Archive Reader,
- kollaborative Dokumenten-Bearbeitung
- gemeinsam nutzbare Kalender
- Umfragen (nicht geheim)
- und viel, viel mehr.

Edit: Link ergänzt
Hintergrund zur Funktionsweise der "In-Chat-Apps":
delta.chat/en/2025-01-23-webxdc-no-billionaires

Super-genial, gerade für Familien und Gruppen!

DeltaChat ist demaßen niederschwellig, dass es fast schon lachhaft ist:
1. Installation,
2. Account mit automatisch E2E-verschlüsselter E-Mail-Adresse erstellen,
3. Chatten.

- keine Rufnummer nötig,
- keine Logindaten,
- minimale Metadaten,
- usw.

Genial einfach. Sicher. Schnell.

Testet ihn doch mal:

we hear you. Changing messengers is serious work. There is no need to rush if you just moved to signal. It's a fine choice. For the time being, it would be suicidal for the US corporate operators of signal's infrastructure to use their power to compromise it. They could loose tens of billions of revenue with customers outside the US if they did. Maybe just consider #deltachat your insurance and a thing to eye mid/long term. Email will not go away anytime soon :)
#deltachat

Du weißt das, ich weiß das, alle #DeltaChat Nutzenden wissen das … mein Zitat war die übliche Antwort darauf, wenn man jemandem diese App vorschlägt.

Es ist immer das Problem einer kritischen Masse. Und Influencer:innen können an der Promo für DeltaChat nichts verdienen, also lässt sich diese App / dieses System nicht zu einer kritischen Masse pushen.

Zum Glück ist DeltaChat für alle Platformen verfügbar und nicht wie #Briar nur einer kleinen Gruppe zugänglich.
#briar #deltachat

Currently testing our new #chatmail server.

WE LOVE IT!

Thanks @delta
It's so simple!

A new project is underway and Chatmail (DeltaChat) will probably be part of it (still testing).

Coming from Matrix, it is a blessing that these options are finally available (see picture)!

Seit einiger Zeit gibt es Chatmail-Server. Diese EMail-Server sind speziell für #DeltaChat konfiguriert. Sie sind schnell und nehmen nur verschlüsselte Chatnachrichten an. Das Problem ist also erkannt und gelöst.
Aber auch bei normalen EMail-Servern merke ich im Alltag keine Verzögerung. Es muss nur klar sein, dass der Versand von sehr vielen Nachrichten unter Umständen durch Ratelimits verzögert wird. Das könnte in Gruppen mit hunderten Mitgliedern der Fall sein.

Dear fans of messenger comparison sports,

How does it factor in that on #deltachat there are many apps that can be used in a chat without requiring a login or even a privacy policy ... And the apps all work like cryptpad but automatically and without requiring any server side hosting?

Editing documents and checklists and calendars are all safely end-to-end encrypted without a server and anyone can write new #webxdc apps permission free.

Which other cross-platform messenger offers this?
