head-ups #DeltaChat users! Want to help us testing the upcoming Delta Chat 2.X release? read here:

https://support.delta.chat/t/android-help-testing-upcoming-delta-chat-2-6-0-release/3922

@atlza De nombreuses familles (y compris celles avec de jeunes enfants sans smartphone) utilisent #deltachat avec plaisir. Nous recommandons d'utiliser les relais de messagerie instantanée par défaut, de réunir tout le monde dans un groupe et de jouer à un jeu comme 2048. Aucun numéro de téléphone ni carte SIM n'est requis.

Il y a des gens ici qui utilisent #deltachat ?

Qu'en pensez-vous ? Avantages/inconvénients ?

Je resterai bien pour avoir un système de chat sécurisé avec les enfants qui n'ont pas de téléphone et qu'un ordi...

Si on l'utilise avec son propre compte mail ça vient pas polluer notre boîte?

#chat

@pancake every post, comment and like in the social network is #e2ee thanks to #DeltaChat, the container super-app, but if you want forward-secrecy-secure ephemeral #p2p communications inside a Delta Chat chat, there is the "Live Chat" mini-app in the store (IRC style plus /me and "foo is typing..." support!!)

@delta

@Cappyjax the EU is constantly trying to break encryption with their "chat control" movement, just hosting yet another centralized instance of #Signal will not solve the real problem, we need a decentralized resilient messenger like #DeltaChat, #xmpp, etc.

@thecannaisseur

Nuestro servidor Undernet procesa unos 300 correos diarios correspondientes a la red de mensajería de DeltaChat @delta Hete aquí que sostenemos una serie de cuentas de correo de bots que sirven consultas para personas que acceden a la web a través del protocolo del correo electrónico que en algunos países, es más barato que el protocolo http/https. Es un servicio invisible, o casi invisible que mantenemos desde hace varios años y que fue impulsado desde el comienzo gracias a la iniciativa de @adbenitez@masto.es / @adbenitez@mastodon.social El tráfico de correos en el server, es totalmente cifrado, por la naturaleza de DeltaChat, pero en realidad no sabía con que magnitud se usaba hasta que simplemente puse un contador en los mensajes cifrados que deja pasar el anti-spam y desde el 14 de abril hasta hoy 14 de julio, van más de 25.000 correos procesados. Si sos una persona que usa deltabot@buzon.uy o juegos@buzon.uy dejame un comentario de aliento para seguir adelante. Personalmente no participo mucho en la red de DeltaChat pero la banco (en el sentido sentimental, no en el técnico... que de hecho, también...) La comunidad de developers es muy copada y siempre que me comuniqué con ellos, me respondieron al toque y evacuaron mis necesidades, son tremendos. Arriba. #deltachat #delta #chat #mensajeria

@Avitus @hpk @compl4xx @gaufff @cwtch @element @signalapp @delta what if your phone number or email does no longer work? did you try to install #deltachat in the last year? it has arguably the easist imaginable onboarding, much easier than signal or whatsapp (that grandma usually anyways only set up with the help of their grandchild :)

but sure, things can always be improved ...

@delta

Any hint what to expect next?

#deltachat #chatmail #webxdc

Good news! Our developments are back into full swing with major new releases expected throughout 2025 🥳

After the shock February dry-up of funding grants we recently secured substantial private donations, wonderfully helping to hit the ground running 🧡

#deltachat #chatmail and #webxdc developments currently use ~600k EUR per year to support a dozen experts and contributors, to in turn help the wider contributor communities, as well as to realize major new features.

#DeltaChat #Chatmail #ChatmailRelay @tech@mk.phreedom.club

@nomadmisha no worries. #deltachat has its own way of UX and UI. This poll is just curiosity about what other messenger's UX/UI people enjoy and what they'd like us to take cues from.

For refining #deltachat UIs and UX we are looking at many other messengers regularly. But we are curious. Which messenger UX/UI do you like most and suggest we take cues from?

@snosrapkungfu I recommend you to give a look at #DeltaChat the onboarding is way more easy and much less resources and disk usage

@babble_endanger I have a #DeltaChat / #chatmail server (https://arcanechat.me) with +4.7k users and it is using only around 1GB of RAM and the more important part, less than 10GB of storage! so I am using a cheap VPS of ~5$/month for it

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 :)

Hey folks. I've noticed #DeltaChat hasn't got a page in #Wikipedia. Do you know sources which would prove its notability so we could create a page for it?

Boosts appreciated. If you don't know sources, someone else might.

#DeltaChat evolved according to needs of people under repression and continues to do so. The more ignorant and exchangeable we make #chatmail relays, the less their operators have to worry. Having metadata-less, fast and cheap instant messaging relays, that can also operate when 99% of the Internet vanishes in a region, is a key goal. Some way to go still but, already now, is there any other real-world solution that provides better service in internet-repressed regions in 2025?

@feyter Matrix arguably has a different UX/UI focus than WhatsApp/Telegram (both morphing to social media and AI chat bots though) and Signal/Delta/ (both refusing AI shenanigans) but indeed, when it comes to decentralization, there is some overlap between #Matrix and #deltachat but then again also fundamental differences. See for example this little thread https://chaos.social/@delta/114728456492885546

We used to look closely at #whatsapp Usability/UX. Not anymore.

Meta is enshittifying WA to become a social media app, charging companies for access to followers, showing ads, and pushing AI slop down the throat of billions of people.

#deltachat remains all about pleasing private messaging UX. Resilient, secure and decentralized. Its trivial to get started as a family, group or little org. Its trivial to migrate between android, iphone, desktop, Ubuntu touch.

@gianmarcogg03 there is a lot of #telegram packs available, the bot supports: https://signalstickers.org/ look for telegram packs there, in the future maybe #deltachat will support #lottie (#ArcaneChat client already supports it) and you will be able to export packs from telegram, there is a bot in telegram that allows to export packs

@gianmarcogg03 it is easy to get it, there is a #bot in #DeltaChat that allows to get #sticker packs from #signal

just send the sticker pack URL shared in the post to this bot:

@Mastodon

@Mastodon I added them to #DeltaChat

btw, the mastodon banging on the computer with "error" on the screen when there is a mastodon error is a low-hanging fruit sticker material was expecting to find it in the pack :D

@fabi1cazenave I would also like that if you block a person in #DeltaChat, their messages simply don't get displayed in groups you share with them, but to be honest unlike in other apps you mention, in Delta Chat there is no public groups, all groups are private and ideally with close people you know IRL, but in practice me and others use it to have Semi-Public groups and there ignoring some stranger to avoid getting dragged into discussions makes sense

@delta

@fabi1cazenave #deltachat supports
1) muting a chat (but not a contact)
2) blocking a contact (which also prevents it from creating a group)
so it may not satisfy your need right now. Many people mute all group chats, and only allow 1:1 chats to cause notifications. Muting individual users might be discussed at https://support.delta.chat if you are interested.

@kyonshi people using classic email servers will be able to write to you, but if you really want to properly be reached in #DeltaChat with encryption which is required for people using public open-registration/anonymous #chatmail servers, you need to share your Delta Chat invite link or QR code, not only #email address

As a side benefit I now have a private server to run @delta on.

Wait, how do you reference that actually? I mean delta chat, which runs over email protocols.

I am available on delta as kyonshi@wilderland.ovh

(Which, as you might have guessed, is also my email address)

#deltachat

@ana_valdi

Ya veras que risas usar wasap sin saber catalán.

Pero el botón me sigue ahí.

Ojala poder prescindir. De momento a fomentar y difundir mucho #xmpp y #deltachat

@nthcdr #DeltaChat mode for #emacs, when? 🙏

@sl there is no evidence simplex is particularly resilient .. eg it's been effectively blocked in Russia even if you host inside the country. Matrix impls have dependencies on element servers (newvector) with widgets for example and even if you host a home server inside a country. With telegram and signal people use proxies ... #deltachat has first class support for managing proxies (shadowsocks/ss also used by telegram so one can use the same place proxies with delta)

We'd like to remind everyone that a self-hosted #chatmail relay is best shared in some wider than family circles. In crisis situations everbody does better when helping others.

A typical 1gb RAM chatmail relay VPS for 5-10 eur per month supports 50k+ daily users.

chatmail VPSes are stateless. You can wipe all disk state, reinstall and chatting will resume. Conversely, #deltachat does not keep or depend on any server state .Operators under pressure do not need to feel bad to hand over data.

Lo que más echo de menos de telegram en #deltachat es la posibilidad de poder enviar mensajes sin sonido. Por lo demás, para mí es un reemplazo más que suficiente.

@flan solo tienes que pedir a soporte que lo cambien para poder usar delta.chat

Lo que no se es si vale escribirles en castellano. En xmpp hay un canal en castellano y portugués disroot.es@chat.disroot.org

@andytseng.bsky.social take a look at #DeltaChat

@miriamkl signal is also centralized, and just as with WhatsApp that didn't have that AI for years, it could come to Signal in the future, better to go for decentralized alternatives like #deltachat

@pbg take a look at #DeltaChat it is decentralized, anonymous, doesn't require phone numbers, is offline-first, has in-chat mini-apps and collaborative tools, and it is much more easier to use than SimpleX etc.

Some people in #Iran successfully use delta with national email providers when outside Internet is cut.

#deltachat designs are #OfflineFirst using delay tolerant protocols. Messages are queued when a path is blocked. email servers are made for this and run at planetary scale.
Messages crossing the border may arrive three days later but they arrive.

Peoples can stay in private touch across time and space, to the extent possible in current breakdown times. Which is what delta is about.

We don't see, or plan, a place for AI in our software stacks. A few notes.

Some attempts to use AI tooling provided nothing of value in the chatmail-core-UI stacks that produce the #deltachat store releases on all platforms.

Some in the community AI-generated a base #webxdc app and fixed bugs afterwards.That kind of worked and was borderline useful.

AI is pretty boring. We have more interesting work to do: evolve private resilient messaging by improving UX, networking, encryption, etc

This week in #FDroid (TWIF) is live:

* #ArcaneChat #DeltaChat get a surge of users
* #PeerTube crowdfunds more features
* Swiss #Woz covers #FOSS (they even have a repo!)
* #AuroraStore improvements
- 2 removed apps
+ 4 new apps
+ 161 updates

Drop by https://f-droid.org/2025/06/19/twif.html

And some background on the current default:

The default of adding a new line came to be, because we were focusing on email at the time and there you can not delete an accidentally sent email.

Now we focus more on #chatmail and on there everyone uses #deltachat and you can delete and edit messages that were already sent.

Most other messengers use "Enter to send".

Should we change the default keyboard shortcut for sending messages in #deltachat_desktop #deltachat

The question is about whether the `"Enter"` key should create a newline or send the message.

The other shortcuts will stay the same:
- Ctrl/Cmd + Enter is always send
- Shift + Enter is always newline

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.

Ahora que algunos gobiernos se están planteando migrar a Software Libre. Estaría maravillosamente estupendo incentivar que, tanto servicios públicos como privados, abran sus comunicaciones y soportes de mensajería más allá de Wassap. Cualquiera me sirve: Signal, XMPP, Element, Session o Delta Chat.
#signal #xmpp #deltachat

Everyone returns to email in the end. We are there already. #whatsapp wants you to add your email to secure your account ... despite all the nay sayers and numerous well funded attempts and claims to kill #email not even WA can do it. #deltachat #chatmail and #webxdc are about deep collab between people, projects and operators to evolve email from within. It is not just about SMTP and IMAP and MIME and OpenPGP which are all exchangeable and can be improved ... Which we set out to do. Cheers.

Hi sou benvinguts i benvingudes.

You may setup "burner" phones for specific activities which may face repression including device seizure and forced unlocking. #deltachat does not require a sim card/number and works #OfflineFirst. Seek out wifi or mobile hotspots to connect. At best form or join affinity groups and pre-establish ephemeral chats so everyone can help each other stay safe. Group onboarding is trivial with delta. Note: Digital tools are only ever supplementary to the security coming from caring for each other.

@artfulrobot goodbye fellow 0.001% the other 99.999% of users have #Gmail, and other classic, ehem, "standard" providers that have crazy sending rate limits unusable for chatting and make it EXTREMELY hard to configure with 3rd party clients, since #chatmail and the new onboarding screen was introduced, A LOT more people was able to actually use #DeltaChat

I am also part of the 0.001% and I think it is ok if it is a bit harder for us but easier for the non-technical masses

Wow when did #DeltaChat on android get so hard to use?! I thought I "should" install it again because I like the idea and used it years ago. But the on boarding is like: what?

Create a profile.

What is one? I thought it ran on email? If I choose New it's apparently a service from nine.testrun.org 🤔 if I choose other I get to list "chat mail" servers 🙄 scan invitation code 🤔 and then finally I saw Classic Email Login. Classic? How about Standard?

Perhaps I was rushing but I gave up.

Today at DIFF in Freiburg: DeltaTouch running on PostmarketOS on a Steam Deck (with a Win7 theme), owned by @ell1e

A hand holding a lilac steam deck that shows a Win7 surface, with DeltaTouch running and shown in the middle. The active profile in DeltaTouch is named "Ellie", the topmost chat is with "Lothar" with one new message saying "hi", followed by the "Device messages" chat with two new messages, preview reading "Welcome to Delta Chat - Delta Chat l...", and the last one being the "Saved Messages" chat with no messages. The picture was taken outside, a parked bicycle is in the background.

#deltachat is secure against server-side group membership changes but for a very different reason than #signal which keeps encrypted group membership data in a central store.

Delta Chat has _no_ central store but implements a rigidly tested #p2p group membership model where servers play no role https://github.com/chatmail/models/tree/main/group-membership

Both signal and delta chat are safe against recently published attacks against #whatsapp that can add members to chats, breaking end to end encryption. https://arstechnica.com/security/2025/05/whatsapp-provides-no-cryptographic-management-for-group-messages

#whatsapp claims end to end security of content but:

- ties your identity to a phone number
- owns your identity
- can see who messages whom and who is in which group etc
- forces you to send local search in your private chats to Meta AI
- does not allow to disable Meta AI on the main screen

None of these problems exist with #deltachat devs and distributors. We have arguably the world's easiest onboarding process for a messenger that offers a Whatsapp style interface on all platforms.

@delta I love #DeltaChat... I collaborate with a small chatmail in delta.cuates.xyz

@ex_06 For now, #deltachat will stay focused on private messaging and rather serves as a decentralized alternative to Signal and WhatsApp although the latter is turning into a social media / AI app which we are not aiming to imitate.

@therainingmonkey

> but there are plenty of apps focused on "encrypted chatting

and even many more for unencrypted chatting and unencrypted email

> This feels a bit like #deltachat is abandoning the thing that made it unique!

and highly unused unlike many of the alternatives, since finding a good email provider for chatting is almost impossible even the PAID email providers have strong limits ex. #Posteo only allows 1000 emails per day (and they count per recipient in the To field)

Since June 1st there is a big sudden surge of new Delta Chat users and so far things are going pretty smooth. We are happy that our #chatmail infrastructure is holding up and that there is growing recognition that #deltachat is a ready-to-use and resilient chat solution. Some stats from the last days, a brief discussion of centralization risks and what we plan to do about it, also introducing a brand-new chatmail OpenCollective with a european fiscal host.

More chats, more carbon, less privacy 💬 Your #Whatsapp message might be costing more than you think.💡Time for a smarter switch: #decentralised, private, and low-impact ➡️ Enter #DeltaChat, the alternative instant messenger 👇

https://en.reset.org/decentralised-efficient-without-being-addictive-delta-chat-is-our-favourite-instant-messenger/

Comparing #XMPP against #email protocols is too limited. What sets #deltachat apart is *vertical integration* and being driven by UI/UX considerations. Cross-platform Apps and Bots use the Rust core library which connects with #chatmail relays and classic email servers based on a higher level API -- abstracting over SMTP, MIME, #OpenPGP etc. See https://chatmail.at

#webxdc apps in turn use an even higher level stable API abstracting over email/xmpp/... see https://webxdc.org/docs/

Hi @delta 👋

I am making updates to https://delightful.coding.social/delightful_activitypub_development and bumped into this interesting #SMTP to #ActivityPub proof of concept. Just a heads-up to make you aware, in case it is interesting for #DeltaChat in some way or other.

https://apubtest2.srcbeat.com/apas.html

Considering that both #XMPP and #Matrix re-invented #decentralized communication while #email was already there, makes #deltachat more interesting.

The fact that DC didn't invent a new protocol for #InstantMessaging and just used the protocol which was already there, and also that how far has it gone, is mind blowing.

At first when I was chatting with @treefit, I already was developing a Matrix client(#chooj) for #KaiOS and it was the only decentralized IM which I was using and investing resources into. I was skeptical but then I thought it would be a good idea to invest into DeltaChat, as well as Matrix. His argument, of course, wasn't good. He was arguing that we need multiple options in the case one of decentralized IMs fail. However this convinced me to give DC a try.

But now, I see that DC has very unique advantages no other messenger has. Their moto is "playing the long term" game. Unlike Matrix which suddenly exploded, DC moves very slowly. As an advantage, DC is much more consistent, hassle free, has less bugs(in my experience) and has better UI/UX than many Matrix clients. But it has got several disadvantages. Matrix has tons more features which DC hasn't got or has added them just recently such as editing messages and reactions. And it is not yet suitable for public groups, like the ones we've got in the Matrix network.

Overall, if you want secure chat with friends or family or other people you trust, DeltaChat is a very good option and the experience is very good. And I haven't seen something like #webxdc in any other IM. However if you want something like #Discord guilds for a community, Matrix is the way to go.

BTW, DC currently lacks funding, thanks to what #Trump did with #OpenTechnologyFund(#OTF). If you can help in anyway, financial or otherwise, it will be extra valuable at this point.

Edit:

BTW, here are websites of webxdc and DC:

https://delta.chat
https://webxdc.org/

Edit2: Make sure to check WebXDC, apps shared in #P2P deltachat groups or DMs.

#IM #FOSS #Messenger #MessagingApp #opensource #opensourceIM #freesoftware

@pixelschubsi @treefit

The point is that DeltaChat didn't invent a new protocol, start something from scratch and write the software for it from the first line. As there is a saying:

Good programmers write programs from scratch. Great programmers find an already existing program and use it as a base.

#DeltaChat didn't invent #Email, #PGP, #autocrypt or new technology for #webxdc. Even WebXDC's real time channels don't use a technology invented by DC.

our friends over at @rpgp just published a monster milestone, humbly tagged 0.16 😍 with

- streaming decryption and encryption

- post-quantum-cryptography

- API streamlining.

#rPGP is a full Rust implementation of #openpgp which counts among the fastest and most compliant implementations today, and includes security audits. Note: #deltachat uses a restricted subset of OpenPGP, and follows best practices (eg using the same ed25519 keys implementation as #signal) https://github.com/rpgp/rpgp/

Mensajería instantánea

De una conversación tecnológica:¿Da WhatsApp (WA) información a la policía?

El entendimiento general es que WA no da contenido de comunicaciones a la policía.

Da metadatos de comunicaciones a la policía, y los metadatos que da son sustanciales, ya que cosas como el nombre del grupo, descripción e icono son considerados «metadatos» por WA (no por Signal), e incluso contenidos de su agenda (y las agendas de sus contactos) se consideran metadatos.

Les defensoras de Signal señalarán que Signal no considera «metadatos» cosas como el nombre de grupo, la descripción o el contenido de la agenda.

La gente acostumbrada a servicios decentes como los de riseup, autistici/inventati, nadir, sinodminio, disroot o aktivix, siempre preferirán protocolos descentralizados donde cualquiera puede configurar su propio servidor federado, como delta.chat o xmpp; son los mejores.

Idealmente hospedados por colectivos decentes.

@tanja yes, there is a pre-discussed concept for sealed sender maybe along with sealed recipients while we are at it. Base idea is to use fixed-format alias chatmail addresses for recipients and allow unauthenticated sending from noreply@chatmailserver to such fixed-format alias addresses (which #deltachat devices learn about through chatting).

La idea de pasarse a XMPP ya como que me remata, porque todo el trabajo de pasar a tu entorno recae en el que lidera la propuesta y para eso hay que tener entusiasmo y fuerza.

Tuve una época en la que estuve usando #deltachat con el correo electrónico y si hay que hacer esfuerzos en promocionar sistemas (en mi opinión) es en el correo electrónico. Mecanismo que empezamos a perder porque todo el mundo tiene uno, todo el mundo lo necesita, pero nadie quiere pelear por el suyo. Igual que con el fediverso.

@rohden Heh, you caught it :) Indeed bots running some LLM for audio transcription or image generation exist. But they are not part of the UI/UX of #deltachat itself, or of its #chatmail core Rust library. Bots and #webxdc apps are behind extension points where we intentionally don't control or even know what people use.

@sommelier @kuulman from the core teams there are no plans to go for ntfy any time soon. #deltachat on #FDroid doesn't use any push notifications and generally works fine in background, and is the best option privacy wise. See e.g. https://mastodon.social/@ati1/114578258005467162

If you haven't seen it, we detail the current state of privacy of google/apple push notifications here https://delta.chat/en/help#privacy-notifications

By design, end-to-end-encrypting #deltachat and #webxdc apps only need ephemeral transport. It's a big deal. Let's compare:

- #matrix home servers maintain a cryptographic forever-chain of cleartext social-graph metadata.

- #WhatsApp servers maintain cleartext metadata visible to Meta.

- #Signal keeps encrypted metadata, hosted at GAFAM

#chatmail relays do not persist any social graph state, also not in encrypted form. A key goal of our designs: chatmail operators can sleep well at night :)

@bjoern @chfkch @delta well it shows that the #deltachat core library can run inside of a home assistant add-on. the same core library is also used for writing bots.

So should be possible, but I don't know #HomeAssistant development enough to say for sure. Like can I expose actions from an add-on, that you can trigger from the home assistant UI, or would I need to extend home assistant itself for that?

The last two days saw the number of push notifications spike. Sometimes 80K Google Play push notifications happened per hour, while the baseline was more around 10-20K. These spikes probably indicate Internet availability. #deltachat is offline-first: you can write messages and attach media, create groups, use #webxdc apps, setup a second device etc. all without any Internet. Once it returns queued messages are sent out and cause push notifications. #OfflineFirst is crucial for resiliency.

Alt...

a graph showing "Direct push notifications for the last hour" On the X axis it starts around May 24th 7:30pm and goes until May 26th 7:30pm. On the X axis it goes from 0 to 80K notifications for the last hour. There are two plot lines: - Apple push notifications which are in the range of 7K and 15K notifications in every hour. - Google Play notifications which is between 10k and 80k notifications per hour. There are around 5 spikes that go up to 70k or above 80k notifications in every hour.

Thank you for the clarification of the verification process and the link to the documentation explaining the process.

#deltachat Desktop can now run on #Firefox and Safari, entirely avoiding #Electron and Chromium! It's an intended side-effect of the "porting Desktop to #Tauri" effort led by @treefit which aims to provide a non-Electron packaged version of the Desktop. Here is a video and deep dive into what's working on regular browsers now, and what's missing for a full Web version: https://delta.chat/en/2025-05-22-browser-edition

For those wondering about Microsoft Recall because of #Signal's blog post about an option to block screenshots on Windows: #deltachat Desktop on Windows and MacOS have an option to disable screenshots in "Advanced" settings since beginning 2025. It's not enabled by default because we first need to work hard on drafting a big blog post about it .... just kidding :) We'll see if we change the default. We certainly agree that Microsoft needs to change their AI-grabbing and privacy violations.

Don't forget there is now an Australian chatmail relay/server up and running folks.

Help spread the load and increase Delta's geographic foot print.

You know it make sense...

@farooqkz @delta #deltachat does not even have encrypted data. only providers may have encrypted data. in case of #chatmail they are ephemeral by default, however. also, there is no group state or things like that

Transparency report: #deltachat gave out data for the following number of users in the last years: 0, nada, zilch.

granted, it helps to not have data to begin with :)

#Telegram is the exact opposite: they have _all_ the data about users, message histories, contacts, group and channel memberships, phone numbers, media files, bot interactions etc .... all in the clear on their central server, ready to be grabbed.

@pixelschubsi @adbenitez we use #chatmail to indicate a minimal mode to operate an e-mail server, namely as an ephemeral store-and-forward relay. On top of chatmail relays, #deltachat provides *always* end-to-end encrypted messaging and minimizes metadata visible to the relay.
Relays forget messages after download, or if a second device is added, after some set number of days. This ephemeral e2ee-only mode is indicated by "chatmail" see also the intro of https://delta.chat/en/2025-03-26-edit-and-delete-how .
