#DeltaChat und #Threema sind auch super #Messenger und Alternativen zu #WhatsApp! Hier noch ein nützlicher Vergleich vieler Messenger-Apps: https://eylenburg.github.io/im_comparison.htm Ich lösche bald mein WhatsApp, yay!! Habe es gestern all meinen Bekannten und Verwandten dort angekündigt und siehe da: Viele nutzen schon Alternativen und ich wusste es gar nicht! :)

I keep trying other messengers, including xmpp which I also love, but keep coming back to #deltachat it's so snappy, clean and I never have any issues with keys/encryption ... it just works!

streamed yesterday: one-hour german #chaosradio @cccfr freiburg feature at @RDL with a deep-dive conversation about #deltachat origins, what it has and hasn't to do with e-mail, protection against server compromise, phone based compared to e-mail networking, how to conspire for baking cheese cakes, authoritarianism and sovereignty, protest and organization, how to arrange for shopping and checklists in chats ... and fun music :)

Die Einrichtung von #deltachat ist anonym, kostenlos und sehr einfach: App installieren, Namen eingeben und fertig! Neue Kontakte lassen sich per QR-Code, Link oder vCard hinzufügen. Ein weiterer Vorteil ist die Möglichkeit ein Profil auf einer unbegrenzten Anzahl an Geräten zu nutzen und eine unbegrenzte Zahl an Profilen auf einem Gerät. Außerdem können in den Chats Apps ausgeführt werden, um zum Beispiel einen gemeinsamen Kalender oder Einkaufliste zu führen oder Schach zu spielen.

Natürlich sind beide WA überlegen. Aber man sollte nicht vergessen, dass es sich um zentralisierte geschlossene Systeme handelt. Wer sagt, dass sich diese nicht eines Tages negativ entwickeln? Man wechselt von einem "walled garden" in einen anderen. Die Abhängigkeit von einem Anbieter bleibt bestehen. IMHO sind deshalb dezentrale Lösungen die bessere Alternative, auch im Hinblick auf Blocking und Zensur. Ich verwende #deltachat und kann jedem nur ans Herz legen, es mal zu testen.

Curious what it would be like to write bots for #DeltaChat? There's a blog post for that

Thanks for the reply! I created a profile on android in the default #chatmail and I used a new account in my email server (custom domain with infomaniak) for a second profile in mz Linux Desktop to check out how this works. I see #deltachat created a new imap folder in my email server and started adding emails there (as expected).

all issues from the ETH Zuerich security analysis were addressed.

There are more audits with the last one being on the Rust #OpenPGP library rPGP where also all issues were addressed.

Maybe even more importantly, #deltachat is focused on actual security outcomes for journalists, lawyers and activists in repressive countries. @Xeniax has done extensive user research and real-world testing. Many findings have been incorporated and addressed in Delta Chat.

Rather to my surprise I seem to have managed to set up my own chatserver, following (both) your instructions. I do have a follow-up question though. How security-hardened would you say the standard configuration is? Do you have any advice on firewalling etc?

Delta Chat is an impressive piece of work.

There is no shortage of startups and enterprises animated by, or outright proclaiming, replacing e-mail as the de-facto open internet messaging standard. VC Investors are forever fascinated by funding such endeavours. #matrix #simplex #slack etc are examples.

#deltachat endorses e-mail but reconfigures and repurposes it to serve for interoperable instant messaging. The #chatmail server network relays end to end encrypted e-mail only, and servers are reduced to dumb store-and-forward relays.

OKAY! NOW I think I got @delta to finally work as intended, lol. Took me a bit to figure out how to do that flatpak thing again but it's running. Drop me a comment if you want to chat with me there. #DeltaChat

Another #deltachat release highlight that we didn't tell about yet: De-duplication of attachments and media files. De-duplication means that if you share a larger file to multiple chats, it will only ever exist once in each sending and receiving device's storage.

Same for #webxdc apps -- so if you use the 650KB big "v86emu" app running 32-bit ISO images, it will also only exist once in storage, even if each instance in a chat creates its own realtime LAN. Mini-tutorial https://chaos.social/@delta/114161626183191989

Having lots of fun using Delta Chat. I've set up two accounts on my mail server, one for myself and one for my husband. We're both surprised at how fast it is compared to more traditional centralised chat apps like Signal. It's so cool to be able to self-host this and not rely on centralised infrastructure that is outside of my control.

Now I just need to convince everyone I know it's really cool :)

Finally finished moving all my two factor authentication accounts to TOTP app and can now uninstall Authy!

You can run it in Delta Chat, Monocles and Cheogram.

Some of the services that work fine:

- codeberg
- mastodon
- github
- npm
- microsoft

IMO, no. I know how big of a challenge it is to get a group to switch communications apps & in your situation I wouldn't.

I still trust #Signal & use it for my groups. If someone were just getting into using encrypted chat, then I would recommend #DeltaChat. I haven't experienced any buggy glitches, it has more upside & I love the community being built around it. It wasn't any harder for me to start using than matrix or mastodon.

I think #deltachat will be the first decentralized instellar messenger with subspace encryption.

Yes, building magic wormhole with iroh direct connections would be cool! Currently magic wormhole traffic is all relayed via a server AFAIK.
Iroh is open source, and you can self-host a relay. And iroh runs on mobiles. E.g. @delta does all of those things and integrates an #iroh relay in their #ChatMail server. And #DeltaChat runs on mobiles.

I'm going to have to install a DeltaChat server now, don't I?

My only issue with #DeltaChat is that it's not compatible with #ProtonMail or #Tutanota. I think that's more of an issue with Proton and Tuta than it is DeltaChat, however.

#deltachat is geared towards private group chats. In small groups technical moderation is not so important. A subset of people can always create another chat simply and continue there. Technical admins can only help so much. Maybe it's even the admin that is the problem?

There are >100 people chats e.g. from #38c3 or #fossdem25 that work quite fine. But YMMV

If you want Telegram-style channels with public subscription, then yes, some administration is needed.
#38C3 #deltachat #fossdem25

Yes, I've just checked, and there is a message delete function.

How it works in terms of group moderation I'm not sure.

My basic understanding is each group member has the same rights/power.

I am unaware of an 'administrator' function though.

"but the email addresses are still exposed"

I can change my email address to another random one in the client -- even to a different chatmail server -- and all my chats will keep working. As soon as you send a message to your peers they will update to your new identity. This is a feature called AEAP -- Automatic Email Address Porting and hopefully soon we'll see a mechanism implemented that automatically enables forwarding of your old address to your new address (to not lose messages from people who don't know about your new identity yet), and then #DeltaChat can enable functionality to automatically rotate you through new anonynmous identities transparently.

The downside of our project approach was that we often got experts being very dismissive on re-using email and #OpenPGP ... and there still is some opposition which often subsides when actually trying #deltachat and #chatmail, looking at security audits and our strong usable security focus.

There may also be surprising upsides. The UK "Online Safety Bill" which attacks end-to-end encryption integrity seems to not apply for ... e-mail. Because everyone knows, e-mail is unencrypted, right? :)

After trying out #deltachat and #arcanechat, I've discovered the #webxdc app store. My Dad loves #Sudoku puzzles, and I was tempted to play some competitive Sudoku with him. What assurance is there that there are no sketchy apps in the webxdc app store? Can these apps break out of their little jail, and root my phone? What would the #infosec community say? There's somewhat of a thread on the "threat model"/security of webxdc here (but I think it still needs more scrutiny):

WebXDC threat model?

Hi, I’ve just came across this WebXDC idea through its implementation in Monocles Chat (which does not appear to be working at the moment, but that’s another story).

I think the only remaining feature I care about in #DeltaChat is better support for large attachments but that's a harder problem.

The comfy feature I'd like but has security implications would be link previews. There's a bot you can add to a group chat which will produce the "quick view" or whatever of a page which is a static HTML snapshot but traditional link previews are nicer as it's rendered as part of the original message.

Besides the security implications of it there's also the uphill battle of sites breaking link previews because of AI scraping concerns so they whitelist iMessage/WhatsApp/Telegram access which screws everyone else over. I see it with Pleroma sometimes -- links won't get a preview because they 403/404 or just don't include the meta tags
#deltachat

Decentralizers, attention! :)

Last #deltachat releases introduced stable #p2p group membership not found in any other messenger. Members can add/remove peers also while being offline, and when everything comes online again, everyone has the same consistent membership view. We formalized and ran a simulation model using #TLA+ (invented by Leslie Lamport of vector clock fame):

https://github.com/chatmail/models/tree/main/group-membership

and a complementary #pytest model with more corner cases tested here:

allez je fais de la pub pour #Deltachat c'est du mail chiffré mais présenté et aussi rapide que de la messagerie instantanée. C'est fédéré (c'est juste du SMTP dessous), les serveurs sont très économes en ressources, ça marche même avec des fournisseurs d'e-mail traditionnels (pas tous malheureusement). Le cœur est écrit en rust, il y a des clients modernes pour iOS, Android, Desktops.

With #deltachat #chatmail and #webxdc developments we aim to instigate a new modern foundation for secure E-Mail and a resilient Web without platforms. We are building a kind of #minecraft system for modern decentralized messaging.

But who are we building it for?

For all who need reliable trustable means of modern private communication.

While our work needs hackers and experts it's not designed for them. @tante raises interesting and important related thoughts https://tante.cc/2025/03/03/who-is-free-software-for/

Who is Free Software for?

For a while I have been arguing that maybe there are some issues with the whole “Open*” movements, their founding myths and ideologies (see for example my talk at Fluconf). This criticism comes from a place of love.

the server is using around 1GB of RAM, CPU is almost unused, and only 1.4GB of storage used for encrypted user volatile data, that is around 1MB per user on average!

the cost of self-hosting a #chatmail server for #ArcaneChat / #DeltaChat is really low! and you don't even need to trust the server operator or even the VPS provider if you are selfhosting since all is #e2ee and safe against #mitm thanks to the green checkmark in chats
