R²M

R²M, or Rusty Retro Messaging, is a written from scratch third-party MSNP server.

This instance and "project homepage" is a private testing one, if you have a code you can register on the top right and use one of the patched installers here. Or you can point your client to this same domain.

Client support

At the moment the server supports MSNP8 to MSNP12, which includes:

• MSN 5.0
• MSN 6.2
• MSN 7.0
• MSN 7.5

Open source and self-hostable

This project is to be completely open source, and as such the source code is available here. Self-hosting it is possible with that code.

R²M is not affiliated with Microsoft in any way. It was created using publicly available documentation written by third-parties reverse engineering MSNP.
