R²M

R²M, or Rusty Retro Messaging, is a third-party MSNP server written in Rust.

Status of the project

It currently supports MSNP11 and MSNP12, i.e. what MSN 7.0 and MSN 7.5 use, and has most protocol features working, including messaging and most contact actions.

The server is actually available for private testing, 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.

Open source

This project is to be completely open source, as such the source code is available here.

Future plans

Eventually, when Polyproto is more mature, this project intends to use it in order to turn into a federated service.

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