>>Where did you put the plugin? I can't get mine to work<<
I just downloaded it, unzipped it and ran it, and it worked.
I made sure that I set OSX Mail like this:
the incoming mail server is hotmail.com
the outgoing mail server is services.msn.com
the outgoing server port is 25
And I used this work around too:
You will need a Hotmail Plus account but this website has a workaround

I downloaded a file there and loaded it on. Didn't put it anywhere in particular, just ran it.
Hope this helps.
