Last Notes npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat Telegram is an extreme security risk for its users, its developers and operators, holding data and metadata for over a billion people on central servers! npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat It's hard these days to find a unifying description, or know about all the people and communities involved in #deltachat #chatmail #webxdc developments. One shared sentiment probably is wanting to develop anti-authoritarian technologies and cultures around it, and being opposed to authoritarian tech policy moves in the West, chat control, age verification, prescribing Google/Apple control, enforcing digital app use etc npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat What do you think is unique about the #deltachat project in the realm of secure cross-platform messaging? npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…fm4q how so? npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat Reminder: There are no accounts in the classic sense anywhere with #chatmail or #deltachat. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…7k5d We are doing our best but mistakes like a wrong link or a misleading link happen. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…7k5d ups, thanks for pointing a bug in our home page! You are totally right to criticize that audits are not the same as security analysis. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat We don't think any institution or state has the right to prevent families and friends from private chatting, physically or digitally. But the Cyber Authority China (CaC) seems to take offense: npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…5pf5 sorry. we edited the original post, reads clearer? Otherwise drop a DM but please keep in mind we have a 500 char limit and dopn't want to rewrite the whole post :) npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat We’ve been busy building and releasing but it’s high time to share some major news: @sovtechfund is investing nearly €500K into #chatmail npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat #deltachat user profiles are private and invisible to the public. No one can discover you, or your children, via phone numbers or any other public handle. Chat profiles exist only on user devices. No PIN and no "SMS verification code" ever asked or needed. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…pqzv we strive towards making relay selection completely automatic, but for now we want to make sure it works at all, and smooth around the edges ;) npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…s63u If you add multiple relays to your profile and change between them, you will appear as the same contact, both in 1:1 and group chats. Internally since Delta Chat v2 all contacts in encrypted chats (the ones not marked with an envelope icon) are identified by their OpenPGP key, and it does not matter from which email address the message arrives, so when you switch to another address your contacts will likely not even notice unless they look in debug info. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…s63u You can switch the sending relay at any time. If you send a message and sending gets stuck because the sending relay is not reachable, you can select another relay for sending and keep sending messages. There is no automatic "failover" yet. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…e3gw the instructions were about adding a second relay. In the screen you posted you can just create a profile and then go to advanced settings. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…e3gw Are you doing this on the phone or on desktop? npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat This morning nine.testrun.org was briefly unavailable, some network problem. A good time to remind everyone to add a second relay to your #deltachat app: npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat "Popularity is overrated" is an often occuring phrase in our circles. Which is of course nonsense because only what is popular, counts, right? Only what everybody else does is a valid choice, right? #deltachat #chatmail and #webxdc are used in private places and communities that people are molding for themselves. We are just providing tools and approaches that work ... At least most of the time 😅 "Nothing works all the time" is another project mantra. Brb preparing the next releases :) npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…ns8p what do you mean with "delta chat advertising obsessed with protocol"? https://delta.chat/en/ and appstore description barely mention any protocol? npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…ns8p @nprofile…vcgd new protocols are fine. The point may rather be that contrary to popular nerd belief protocols are only one part of an effort. What distinguishes #deltachat from #xmpp is that one is a cross-platform mass-user focused app with a consistent UX across the platforms and using standards under the hood, while the other is a set of specs with many different implementations and UX approaches on the various platforms, and sometimes tenuous compatibility between them. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat the public #chatmail relay list https://chatmail.at/relay covers about ~20% or so of chat relays we heart about and have traces or hints from, and we definitely don't see everything -- which is how it should be :) npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat What if all public funding and all private donations to our efforts stop tomorrow? npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…dysu @nprofile…4e7w thanks for the praise, much appreciated. we are indeed constantly working to improve and refine UX. We hear you but need to work with 1/100th of signal resources. Our last release contained two big cryptographic and network layer improvements but then also a lot of UI goodies. In this section, in particular, we try to remind the crypto/network enthusiasts among us about the importance of user interfacing https://delta.chat/en/2026-03-31-zero#at-risk-user-needs-1-availability-2-telegram-3-security npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat First Signal, now WhatsApp is rolling out usernames -- to protect against the privacy leak of identifying phone numbers (except the tiny detail of phone numbers leaking to them). npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat After three intense months of work from more than a dozen contributors, #deltachat 2.48 releases are rolling. Maybe the most feature-packed releases ever? npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…063m we are lightly following its developments but are not impressed by its UI/UX, and also don't think they particularly care for resilience (they are blocked since >15 months in russia, and don't do much about it, for example), also they don't appear to care much for people with small data plans and bad networks, and rather tune everything for resource-rich always-connected users. They also appear to be going down the crypto-coin rabbithole quite a bit. YMMV. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat End-to-End Encryption is good but metadata protection counts as much. Names, group descriptions and memberships, avatars, who talks to whom ... npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…eld0 you can well use regular IMAP based inboxes and standard email servers. It's the mixing of cleartext and e2ee clients on the same email address that is problematic since years already, as it caused a lot of implementation work on our side, and still not nice UX in some cases. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…j4kk @nprofile…zjzz @nprofile…tpt8 could be possible. Maybe discuss/check on https://support.delta.chat? npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat The last two weeks saw a dev gathering in the black forest from several in #chatmail, #deltachat and #webxdc communiities, also joined by @nprofile…zjzz and @nprofile…tpt8 folks. The tech demos and hacking results we presented to each other, were pretty mind blowing and tracing a path to very interesting futures, delivered in working code, not just some grand plan. Let us just say for now that we are getting to the fun parts of an age old http://testrun.org motto :) happy equinox! May the tides turn! npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…selc is this friend using FDroid or Google Play install? Which version of Delta Chat? Can your friend try "Settings -- Notifications -- Force Background connection" to see if it that helps? npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…xs6q audio message playback improvements are coming or available with 2.43 which is rolling out. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…aejy For chatmail relays default message size limit is 30 MiB. We don't know if anyone changes it, but even if you change it your recipients need to be able to accept it as well and have inbox large enough to accept such files. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…aejy If you have enabled VPN system-wide, as shown e.g. with a key icon in the status bar on Android, then there is nothing else you need to do to make Delta Chat use it. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…aejy Delta Chat does not have any special proxies, it supports SOCKS5, HTTP(S) proxies and Shadowsocks. Tor works. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…dd4h It is already written at https://chatmail.at/doc/relay/getting_started.html#minimal-requirements-and-prerequisites that "build machine" needs key-based SSH access to the server. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…e40t luckily, an estimated 99.9% of users don't need to buy DNS or a VPS to use delta chat -- and probably around 98% don't even know what these TLAs mean :) npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…dd4h If your SSH key is password-protected, run "ssh-agent bash", then inside the shell unlock the key with "ssh-add", then run cmdeploy npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…p36c we are not abandoning email but de-prioritizing cleartext email. IETF-standardized protocols remain in use across the board, including modern OpenPGP based standards. We are "encryption first" and use the email system for encrypted decentralized communications. Many different server implementations and operations work just fine. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…du6u sure, email addresses as human recognizable handles are nice! We do have discussions to re-introduce email addresses for this use (tell someone your contact address and that's it, no QRs, weird links etc.) but it will be about establishing end-to-end encryption. It's not a current prio but it's definitely something that we can think about and do. FWIW https://securejoin.delta.chat already implements automatic secure hand-shaking for establishing E2EE. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat Our strong focus on end to end encryption and zero metadata does mean that one of the original project notions of "you can use delta chat as a lightweight cleartext email client and your contacts don't need to care" was deprioritized since some time now and remains available rather for specialists only. It used to be encrypted mail that was hard to do and only for experts. Delta kind of reversed this. Now it's hard to do cleartext. But you can self host your mailbox addresses. No changes there! npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat some insights from #deltachat forum gardening 🌸 npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…dysu you're not doing anything wrong ❤️ "@nprofile…cwnm", so called "mentions", are not implemented yet, but discussed at https://support.delta.chat/t/direct-mention-on-groups/185 npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…xxh4 there are several teams and project areas and wider contributor circles. So it's hard to give a unified answer as we haven't discussed it widely yet. In any case anyone submitting to key repos needs to sign off personally on it, and it's human reviewed and merged. AI slop issues and PRs and "security findings" are usually closed immediately. Generally there is a lot of skepticism and critique on using LLMs, training data etc but also curious experimenting in various corners. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…fyvh Annoying sync times/processing after longer offline times is a known problem for heavy users of delta, and you are not alone having it. So far it hasn't been prioritized because focus is still on removing obstacles and making it easier for people who freshly join. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…7q8k yes, you can use dedicated mail boxes on your own server and it works with chatmail relays and other email servers. Proper TLS and dkim is needed, typically. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…y3sx could you expand what you consider bashing here? It should be fine to point out differences in architectures and how identities are handled in messaging systems, no? npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat #DeltaChat breaks the one app, one ID rule of phone-number-based apps by supporting multiple chat profiles. This allows for true private messaging where you can keep a public identity for the Web or Fediverse separate from a private one for family and friends. Managing multiple selves is a new experience for many, but it is key to digital autonomy. We are working to make multi-profile handling even smoother in upcoming releases to ensure switching contexts is seamless. (3/3) npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat The total privacy of #DeltaChat has a trade-off: there is no global directory. Connecting for private messaging requires a direct QR scan or using an existing channel to exchange invite links. The hurdle is often the readiness of friends, family, or those around you to switch. However, once connected, the app is an enjoyable daily driver. It is about moving to a space where you cannot be found by strangers, but can still enjoy modern, reliable chat with those who matter. ... (2/3) npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat While platforms like #Matrix or #Signal manage user identities on a server, #DeltaChat and #Chatmail are not platforms in the classic sense. They operate without a central registry, meaning there is no central gatekeeper to grant or deny access. This setup for private messaging naturally complicates invasive age verification. Without a public registry or user discovery, there is no technical hook to verify users. #Chatmail also enforces E2EE by rejecting all unencrypted data. ... (1/3) npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…et8j not easily. Conceptually, operators have no way to send unsolicited messages to their users. It's not quite 100% true yet but we are working on making it so. We are also going for multi-relay support which means that the downtime of a single relay out of three you might be using, does not matter. Chatting will continue unimpeded. Please see the Fosdem tallks we posted about earlier, especially this one: https://fosdem.org/2026/schedule/event/3F9VTU-deltachat-chatmail-relays-multi-transport/ npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…gry0 maye try again. A looooooot has changed. You don't need an email address, and in fact users don't need to understand or know the email system is relaying messages. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…aejy of course delta chat supports end-to-end encryption and a pretty solid and audited form at that. See https://delta.chat/en/help#e2ee for more details. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…m6h0 congratulations! You have done an incredible job showing and living the power of free and open source decentralized infrastructure and culture! We are very grateful and humbled that you could put to use our now years long efforts on providing decentralized resilient #foss messaging infra and apps, for anyone to use, inspect and modify! Wishing all of you the best of luck, health and safety! npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…8ht9 No, that's what the long-term fallback key is for. That will be used, if no recent rotating key is available. This way, you avoid unable-to-decrypt errors, while still protecting against store-now-delete-later in most cases. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat It took a while but it's shaping up nicely :) Post-Quantum Cryptography and Reliable Deletion, better known as Forward Secrecy, are going to become available in 2026 in #deltachat. For more details, including the recent #fosdem26 talk recording: npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…432y when you loose the last copy of your chat profile then the identity is gone and unrecoverable. However, you can always create a tar file in settings - chats and media - export, or you can setup a second device. Each device is autonomous and does not depend on the original one. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat Our second #FOSDEM talk is about to start: Hocuri talks about the upcoming #multirelay profiles, which use more than one address to exchange messages! npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat Now in the #FOSDEM live stream: Holger Krekel introducing #autocrypt2, a mechanism to protect against store-now-decrypt-later attacks, to be introduced in Delta! npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…2786 thanks, really nice background image btw :) npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…2786 you might have fun with some of the retro-games available via "attach app" npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…7gnc yeah :) we reverted a recent change to make it work again. More info would be very helpful in fixing it, so we can do the change properly this time :) npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…7gnc thanks, we will look into it.

You can also go to settings/chats and media/export backup and then on the other device import that file via "i already have a profile" from the startup screen. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…q45s you can also get a link out of a QR code and ingest it on the other side via paste. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…g0nf well, chatmail has higher rate limits, but then several hard restrictions: only end-to-end encryption allowed, only strict TLS allowed, only strictly validating DKIM allowed. Not sure this counts as "less restrictions" overall :) npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…g0nf maybe take a look at the front page https://chatmail.at/ and follow links from there if you want to know more. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat #iran mostly shut down now their own state-aligned national messengers that they previously positioned as alternatives to Western messengers and Telegram, especially for when the internet is nationalized and locked down. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…m7ms proton via a proxy some people managed to get working. But we don't recommend it. And with tuta you are probably right. We just got a question from someone about using tuta with delta which is why this slipped in 😅 in any case we do value their privacy focus as well. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat PSA We are happy about the wealth of privacy focused classic email providers (proton, tutanota, posteo, mailbox.org etc) but they are not geared for instant secure messaging. Do yourself, family and friends a favor and use delta with any of the many https://chatmail.at/relays npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…qrmx we doubt it. Better use any of https://chatmail.at/relays would be our recommendation. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat Our stance simplified: we want to make private communications available to anyone on the planet. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…9q3v yes, channels scale in ways that group chats do not. In channels, the message size is constant no matter the number of recipients. In group chats message size grows with the number of members. In both cases, if a message is delivered to a hundred recipients on a relay, it will only take disk space once. So overall, channels should have pretty good scalability characteristics. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat Abdanan, January 7th 2026. A 40K people city in Iranian mountains where people took over all police and government buildings, as far as we gather. Internet blockades are happening intermittently in various forms. There a massive sense of uncertainty and panic, also from the government side. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…n8na currently, #deltachat works everywhere, including china where it's a kind of secret tip on remaining securely connected when cross borders. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat several people reporting lately that #deltachat has become their main app: They are now spending more time in the chats, also with web apps, than in any other app. It may be a turn to more private communications when social media has become more toxic, obnoxious and dangerous in many places? npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…s8xx nevermind, maybe we just wait for the "0days" then, and leave your generic comments alone even if misleading. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…s8xx Is it too much to expect a bit of precision in your analysis and statements? Doing some click-bait comments like "their code: disables TLS security to support legacy 1024-bit RSA" is very misleading. The *opt-out* to allow 1024-bit RSA is for real-world people that can not change anything about the fact that the server they are using only offers RSA1024. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat @nprofile…s8xx please read more carefully the source code. You are in the "else" branch of "if strict_tls" and strict_tls is True by default. npub16zxpwcght62n7q4j88uj6ynehdqfzk572rues3y2tshr0vehfwjq2v4ynp Delta Chat We are looking for an experienced Android UI developer for https://github.com/deltachat/deltachat-android.

Better ask other people of the author of gpgfail.
