I did have some problems sending a report through msn about a build with luntbuild. It turns out that the library used for msn uses an old protocol. There is a jar file in the directory WEB-INF/lib called msnm.jar. You can download a newer version from the following website:
I downloaded the msnm-lib.tar.gz file, this file contains the jar file msnm.jar. After copying this new jar file over the old one everything works fine.
Now we have a nice message in our msn client. Cool
