Thanks for your assessment and the details related to Delta Chat’s functioning!
Maybe, but keep in mind that it was just one example of many. I’ve experienced such issues on five servers, small and large ones in different countries, both for sending and receiving. Also, I’m not connected permanently to the internet and mostly just connect once a day to check and/or send mails and messages.
Another example is that sometimes e-mails arrive several days later via IMAP while they’re already visible in the web interface.
Of course I can’t say if any of those problems is caused by deficiencies in the protocol. I just want to mention that they are common in my experience.
Exactly, I know him personally and we have shortly discussed that the projects could benefit from each other’s experience. That’s how I got the idea to mention the topic here.
All right, I was just thinking that it’s a protocol that can be expected to gain popularity as it’s standardised and working with IMAP as a developer is a pain (at least it is for me and I have heard similar opinions from others).
Once it’s more popular, I assume it would be reasonable for Delta Chat to implement it, if only to support JMAP-only servers that could appear then. Then we could also find out if a good part of the random lags and other issues would be solved with JMAP.
