blabber.im

Preamble: In this article, I describe the installation and configuration of blabber.im. I wrote it in June 2021. Since then, new blabber.im versions were released. Today, some steps of this tutorial might differ. I will update this article soon. Update 2022-10-02: Trashserver.net has been removed from the list of providers. blabber.im is a good choice if you are looking for a free XMPP messaging app. You can get blabber.
