Back to the future with Delta Chat

Thanks to Andreas we recently discovered something great…

…and its name is Delta Chat!

Before you move away: No, it is not yet another messenger. Or is it?

It is something in between. Delta Chat uses email to transport its messages. Your email server.

Delta Chat does work with "autoconfig". Enter your mailcow email address and password and your are ready!
Delta Chat automatically encrypts messages using Autocrypt – no setup needed!
mailcow comes with a sieve prefilter to move all chats to the preconfigured DeltaChat folder (since commit 3dece1)
Communicate with any email recipient, every client uses their own email server.

So what do I need?
