Hi,

I received a hint that Microsoft would be announcing
a sender authentication protocol soon. 

Does anybody know what this is?

Funny thing is that I had been contacted by Microsoft
in march because of RMX, but they didn't give me a second call. 

Does anyone know more about this Microsoft thing?
