This open letter explains how the XMPP standard offers a proven foundation for NTA 7532, supporting vendor-independent and interoperable messaging. By engaging with initiatives like NTA 7532, the XSF promotes open, privacy-respecting communication technologies and invites collaboration with Dutch healthcare stakeholders and the global XMPP community. [Read More]

MongooseIM is a scalable and efficient instant messaging server. It implements the open, proven, extensible and constantly evolving XMPP protocol, which is an excellent choice when it comes to instant messaging. To communicate with other XMPP entities, the server uses three main types of interfaces, listed in the table below. XMPP Interface Purpose Connection type Reworked in version C2S (client-to-server) Accept connections from XMPP clients inbound 6.1.0 – 6.4.0 S2S (server-to-server) Federate with other XMPP servers inbound/outbound 6.4.0 Component Accept connections from external components inbound 6.4.0 The C2S interface was reworked and improved already in version 6.1.0 (see the blog post), making it more modern, organised and extensible.
