@mray matrix is arguably the heaviest server state machine, as it keeps most objects forever (Block chain data structures), followed by WhatsApp and xmpp that keep lots cleartext metadata and finally signal which at least tries to keep all server state encrypted.

@fox84 @delta Chatmail is another sub-project of DeltaChat. Same team.

@fox84 it's driven by the #chatmail community, with a sizable intersection of #dletachat contributors. Around 30 operators are discussing further developments and there is a separate core relay dev team who enhances the relay setup emplate as needed and in scope of resources. Financial contributions welcome. https://chatmail.at

@fschulze no, queued/non-retrieved messages are simply lost. Wiped chatmail servers are a relatively rare event. And with some other resiliency oriented R&D occasional wipes could be tolerated and not cause message loss.

@ag1km currently, if you completely loose your relay domain, you can not move to another domain and are stranded. We plan to alleviate this soon. A big funding gap earlier in the year threw some of our timelines into chaos but we are recovering and regaining steam.

@mro should be fine if it can run debian 12

@ChrisUplus would be great if someone tried the ionos offering out. Sometimes cheap hosters block port 25 but if asking nicely they often open it. In any case, we will try to offer setup help (send a DM to establish contact) if needed.

@alandes Most #chatmail operators we know off will not hand out data without a fight. But there are other operators who are afraid of brutal prosecution and here it helps that there is not much data on disk in a chatmail server. No need to risk imprisonment or worse.
