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

Or setup a relay of your own if you feel like it. Or use a a dedicated chat email address on your own or any classic email server that has reliable service and no obnoxious rate limits or annoying spam handling. Cheers.

Our stance simplified: we want to make private communications available to anyone on the planet. Problem: governments everywhere tend to want to control and contain private communications. While Iran and Russia might be contemporary poster examples trying to control private communication, almost all of the "Western" countries have similar control-tendencies, EU Chatcontrol, UK Online Safety Act, US KOSA etc.pp. And we often call those out. Without private communication, things are bleak.

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 is a massive sense of uncertainty and panic, also from the government side. We hear of many people succeeding in using #deltachat and #chatmail relays, and are trying, to the best of our abilities, to help people set up communications so families and friends can stay safe.

Remote collab is fine and the default. We meet in person every few months in the black forest or other occasions/places. We can do 20-30 hours per week contracts with 4-5K EUR pay per month. Drop us a DM if you are interested. #FediHire

Don't believe those who loudly claim email can not avoid metadata! They are ignorant of our continuous works on minimizing metadata: DONE: - no phone number other identifying data needed - no cleartext "Subject" - no cleartext "To" - randomized "Date" - no IP addresses - group/avatar/attachment/etc metadata only contained in encrypted message parts Upcoming: - servers to never see cryptographic ID metadata - remove "threading" and auxilliary headers - experiment with Sealed Sender

#39c3 .ending .. quite an enjoyable blast, and thanks to all the wonderful people just dropping by to say "thank you, it all works very nice for us"! 🥰 Certainly raised team spirits :) This year around, apart from one #chatmail relay setup workshop we didn't do any registered events at congress. Pushing out releases, Illnesses and engagements in various other organizing prevented more public sessions. Next ones will be around #fosdem2026 where also several of us will be around. Cheers!

Iran may be on the verge of Internet shutdowns again. If you have friends or family in #Iran, now is the time to let them onboard for example with https://tiiiz.ir -- because using in-country servers helps to stay connected. If you need support for setting up a relay in or for Iran, send us a DM and we'll see to connect you with other knowledgeable operators. با آرزوی فردایی بهتر...

Relax 😎! GPG is not OpenPGP! Yesterday, vulnerabilities were published

gpg.fail

but they don't affect #deltachat or any other #chatmail client because A) We never used #gnupg for anything; we use the modern #rustlang #openpgp implementation @rPGP, security audited multiple times. B) #openpgp is fine, as modernized in #RFC9580, which already warns against several #gpgfail issues (gpg has not implemented that spec) Please spread the word that #gpg is not #openpgp ... Thanks!

Quite a few of #deltachat #chatmail and #webxdc folks are already and will be around #39c3 -- on-site you can join a group chat (or send us a DM upfront) where we announce dynamically scheduled sessions. You'll find us mostly around Komona but also other places ... for more info:

along with templates to replicate the setup, without needing any permission. Two weeks ago we thought there are 60 relays when a hacker handed in a 100+ list 😂 A bunch of knowledgeable folks are now maintaining track of health of the evolving global network, and supporting new operators. 💜💥🖤 thx also for all the support here on the fediverse! its been a wild year and #39c3 is in 13 days to top it off 😅
