eJabberd IM server

Do you need to run an instant messaging server which uses the XMPP/Jabber protocol? Check out ejabberd from Process One. Ejabberd is an open source, high-performance, robust Jabber-based instant messaging server developed and supported by Process-one. Using the Ejabberd server, you can build Instant Messaging services for a service providers or set up your own Instant messaging services. The server is probably the most scalable and the most robust Jabber server around but it is still not largely known.

Ejabberd is also cross-platform, distributed, fault-tolerant, and based on open standards for real-time communication. It can be suitable for small or large deployments on Linux, Mac OS X and Windows.

Process One can customize your ejbabberd server with extensions or entire applications to fit your specific needs. They also offer consulting services, support and training. They even have an Erlang support team who can help your system administrators manage your ejabberd application.
