Related HN post 6 days ago about COI (Delta is discussed as well): https://news.ycombinator.com/item?id=19216077

So, does it clutter up my inbox when I use it? Or does it delete the messages on arrival? Or does it file them in a special IMAP folder?

This was also apparently asked the last time this was posted to HN and still isn't answered in their FAQ :(

Tried it a few days ago and it made a quite polished impression. I hope COI and Delta.chat will join forces and define a standard algorithm to convert e-mails to instant messages (and e2e encryption).

Otherwise, we might end up with incompatible clients within the same protocol.

They do use a common core: https://github.com/deltachat/deltachat-core

This looks really nice. Can't wait to try it out later today. Anyone with a gmail account can use it, and there is no need to install the app if you don't want to.

My main complaint about DeltaChat is that their threading model doesn't work with gmails threading model.

As a result when using it to message gmail friends their inbox is cluttered with a new thread for every single message I send. I haven't checked if it's due to the subject changing or if they don't properly set In-Reply-To/References, but its mildly annoying for my contacts.

Of course if they are properly setting In-Reply-To and References headers in the message, well then my complaint is really with gmail.

Is this the same as the COI protocol[1] that came up a few days ago?

I'll attend a meetup where the authors of Delta.Chat will be present tonight and will ask about this. It's something I was wondering about as well.

Will post an update here when I know more...

The COI FAQ says:

"We are cooperating with Delta.Chat for it to also use COI to provide more features, we are contributing to the C-Kernel of it."

Exactly, that's what I was told yesterday as well. They're collaborating on https://github.com/deltachat/deltachat-core
