Delta ChatOrganizational note: It might appear that <a href="https://chaos.social/tags/deltachat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#deltachat</a> <a href="https://chaos.social/tags/chatmail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> and <a href="https://chaos.social/tags/webxdc" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#webxdc</a> 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 ...

Das teure im Monat ist die IPv4. Die kostet um die 5 Euro. Daran ist nichts zu andern. Für den gleichen Betrag läuft der VPS insgesamt bei Hetzner mit Windenergie. Dazu von mir nur noch ein 🤷🏼‍♂️

Peter VágnerPlaying with various technologies tonight. Managed to setup a brand new debian 12 systemd-nspawn container. Now looking through various documentation and other internet sources to combine it to a working <a href="https://fedi.ml/search?tag=chatmail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> relay server. The thing is I only have a single IP address on the host system so I need to adapt it so the nginx running on the host either redirects or proxies to the container. Plus I guess I need to share the certificate in some way so postfix and dovecot can use it too.

DIGITAL PRIVACY .DIY<a href="https://gladtech.social/@avoca" class="u-url mention">@avoca</a> <a href="https://mastodon.au/@josephb" class="u-url mention">@josephb</a> is there a specific reason to have one in AU? You could use netcup or whatever else is out there (cheap). Spend your 70 yearly instead.If speed is the reason we're currently testing our <a href="https://fosstodon.org/tags/chatmail" class="mention hashtag" rel="tag">#chatmail</a> server in Germany and clients are in New Zealand etc. You can't really tell any difference. You send a message and it arrives ;) And law is also better in Germany as in AU.Or is it just: Because, why not! ;)

Delta Chat<a href="https://chaos.social/tags/chatmail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> 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.

Delta ChatThe 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 <a href="https://chaos.social/tags/deltachat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#deltachat</a> R&D around <a href="https://chaos.social/tags/chatmail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> relays and <a href="https://chaos.social/tags/webxdc" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#webxdc</a> 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 <a href="https://delta.chat/en/2025-01-23-webxdc-no-billionaires" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://delta.chat/en/2025-01-23-webxdc-no-billionaires</a>

DIGITAL PRIVACY .DIY<a href="https://chaos.social/@delta" class="u-url mention">@delta</a> Your chatmail relay is great for private conversations! But it's also great for some Alertmanager infomails!<a href="https://fosstodon.org/tags/alertmanager" class="mention hashtag" rel="tag">#alertmanager</a> <a href="https://fosstodon.org/tags/prometheus" class="mention hashtag" rel="tag">#prometheus</a> <a href="https://fosstodon.org/tags/deltachat" class="mention hashtag" rel="tag">#deltachat</a> <a href="https://fosstodon.org/tags/chatmail" class="mention hashtag" rel="tag">#chatmail</a> <a href="https://fosstodon.org/tags/monitoring" class="mention hashtag" rel="tag">#monitoring</a>

Delta ChatEaster/April offer 🐣 if you are onboarding a small group of family/friends to <a href="https://chaos.social/tags/deltachat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#deltachat</a> and/or want to setup a insta-federated <a href="https://chaos.social/tags/chatmail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> 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 :)

Delta Chat<a href="https://mastodon.ie/@Tina" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@Tina</a> do you mean <a href="https://chaos.social/tags/chatmail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> relay servers when you say fastmail server by chance? As to electron desktop, a) it's pretty fast and all networking and encryption is done by chatmail core Rust library, while the rendering part is blocked from any network access b) there is a Tauri version in development but not quite there yet. If that's the blocker maybe check back in a few months. Cheers.

Delta ChatIf you are using <a href="https://chaos.social/tags/deltachat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#deltachat</a> with a <a href="https://chaos.social/tags/chatmail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> 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.

Better late than never! :)- Key management is automatic through <a href="https://chaos.social/tags/securejoin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#securejoin</a> and <a href="https://chaos.social/tags/autocrypt" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#autocrypt</a> protos- <a href="https://chaos.social/tags/chatmail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> relays form an end-to-end encrypted email enclave interoperable with any e-mail address using proper end-to-end encryption. - RFC 9580 "cryptorefresh" is rolled out in current releases and will be activated soon. One to go? ;)

Blake LeonardI might fire up Android Studio and take a swing at building the most basic <a href="https://infosec.town/tags/chatmail" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> app possible (sign up, add contacts, send and receive messages while the app is open, remember all of those things). I'm claiming the name ThetaChat. I will let you know whether I succeed before sleep.

Delta Chat<a href="https://infosec.town/@blake" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@blake</a> 1) Many people want end to end encryption by default and only. Signal has dropped SMS chats three years ago. Mixing cleartext and e2ee is problematic from a usable security pov 2) Several <a href="https://chaos.social/tags/chatmail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> operators in repressive situations/environments want to be sure their servers do not contain data that can hurt people. Strictly requiring end to end encryption helps. 3) We use IETF standardized protocols for interoperability and discuss with other MUA devs and help where we can.

Blake Leonardabsolutely wild <a href="https://infosec.town/tags/deltachat" rel="nofollow noopener noreferrer" target="_blank">#deltachat</a> / <a href="https://infosec.town/tags/chatmail" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> idea: MLS-encrypted XMPP message packets, as the email body

Delta Chat<a href="https://chaos.social/tags/openpgp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#openpgp</a> traditions and <a href="https://chaos.social/tags/signal" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#signal</a> 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.<a href="https://chaos.social/tags/deltachat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#deltachat</a> avoids such cleartext identity bindings by creating random <a href="https://chaos.social/tags/chatmail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> 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.

Delta Chat<a href="https://fosstodon.org/@AAMfP" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@AAMfP</a> <a href="https://fosstodon.org/@goose" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@goose</a> <a href="https://fosstodon.org/@dammn" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@dammn</a> yes, our whole project is about proving in reality (meaning: working code) that email protocols can be streamlined for instant messaging. <a href="https://chaos.social/tags/chatmail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chatmail</a> relays provide low latency always end to end encrypted interoperable messaging. The family of <a href="https://chaos.social/tags/deltachat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#deltachat</a> 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.
