Thanks, but I'll prefer a decentralised, end-to-end encryptable, well established messaging infrastructure with a rich choice of user and transfer agents. It's called e-mail.Actually, matrix.org aims to be that as well. It probably doesn't yet qualify for "rich choice" (e.g. there is a matrix-client.el but it doesn't support encryption yet), but other than that, it's pretty much there.
The project currently lists many more clients (https://matrix.org/clients/), and here (https://matrix.org/clients-matrix/) 12 clients are marked to provide E2E encryption. The most used client is probably Element, formerly called Riot (https://element.io/). The link to its Linux version is not placed nicely visble, it is below the Desktop Clients for Win and Mac behind the comment "Also available on Linux", which points to a repository which can be used for installation and updates. This Element client works flawlessly.
Concerning the server, You could also run your own matrix server, if you cannot find a provider which you trust, it is all open source.
Good Luck, and sorry for having driving off topic. Marco.
